P2j Vti head P08 cam tech | info | by SRDmotorsports 

Thanks brother! One thing sure I’ll be the same I won’t be a jake zyrus 😂 stay safe and blessed man!

​@@SRDmotorsportshahaha.. this Jake Zyrus joke.. love it..

I’m sorry now I still laugh after I reread my comment hope it doesn’t offend anybody 😂 I just meant il be the same as me 2yrs ago vs now 😂

yes i agree on the thermostat stuff it is why alot are susprised i get 13-14km/liter city driving and i aint stock

Nice… keyword “vti cams and valvetrain” heheh that’s strong 110whp in Autoplus ! That’s a strong ph12!

hey the six letter word might have the video reported thats why i didnt say it 🤣 But yeah the example of the red lxi i said on the video? was from my area and its just sad to imagine how much he spent only to lose by 3 cars vs his friend right? i mean just giving more awareness to give people better value for their money... Thank you for checking this out and thanks for laughing at that 🤣 as i was when i had to write it in words lol

@@SRDmotorsports it's very sad to imagine losing to 3 cars anyhow you made me laugh tho, Man such a great content though I love it, keep doing what you do SRD!

@@omar_alanany ahaha thanks man i had to keep it humorous cuz it was a sad incident i mean after a month? red lxi owner sold it 🤣

@@SRDmotorsports so sad that he sold it real quick! Ahahahaha man I'll stay tuned with your contents, I love your channel! GodBless

@@omar_alanany thats when we found out it was on a 4.7 fd he had to declare it so the price is fair so we were like "hmmmm" lol

Oh thank you Daddydave!! Nice from Norcal ftw Actually you termed it better than I did! Injector “phasing” is the word!! Thank youuuu

relate meaning? they push u to that? lol kidding glad this helps ur future plan dude!

@@SRDmotorsports trial and error chief with the other project. End up, cries per gallon 🤣 Sure it does help 100%

@@midnightkaiju just dont repeat the expenses x2 but keep the learnings then yes yes

Hahaha wow thanks man glad the videos helped! I too am kinda tired of “Lodi” vlogs that sometimes actually promote new enthusiasts that are ALWAYS prone to budol Oh no I didn’t say that lol

Nice an Eg hatch? Nice engine for sure it’s prolly still on top shape

my example was the same a red Lxi was 3 cars slower than a stock d15 done by a local shop 🤣

Thank you!!! actually thats the main reason for this video because i realized my other videos? can be found elsewhere as far as info sharing but this local scenario has yet to be explained anywhere to avoid future money wasting moves and to explain other people's dilemma actually on the video i did talk about the head on the latter part the vti head we ported to be a straight vti but on tuned ecu? surprisngly it only lost by 1 car testing vs a 20camlobe engine so when u think about it? malakas na vti un ah 🤣 so in that sense ur bone stock vti may be better with a proper tune and rechipped ecu so thats good

@@SRDmotorsports Thank you once again! With this I gained knowledge and at the same time saved a bunch of peso! To more subscribers! 💪🏼🙌

@@rinanligan9445 thanks too! this atleast lets me know we share correctly :) perhaps just a cold air intake on ur vti aside from ecu tuning will be worlds difference in performance

@@SRDmotorsports wow! Though I am currently using a stock airbox with k&n filter. Will HKS do the job? 😅

@@rinanligan9445 yeah those kinds work well

Doesn’t bolt up cuz the top most bolt is misaligned but possible, But the camgear side is still off that’s where everything went off, so to correct it by the distributor means it’s camgear is off by half a tooth or vice versa as mentioned on the vid

Well I'm shit outta luck smh, guess I'm running slow/high on fuel for now Now that I think about it, a coil on plug conversion deletes the ICM and coil, so that would solve that issue. No?

@@tayvonrose2528 nah man still can solve it somehow I mean get a timing light and see where it’s at… and try to get it to 16btdc And if it can’t reach it then check the camgear cuz they both connected to the same thing “the cam” and the dizzy u will see something making sense by adjusting

@@SRDmotorsports lol, I thought timing the dizzy with a gun is a given. The tuner/builder mentioned in the video never did that? I've seen some people slightly bore out the bolt holes to get the timing right.

@@tayvonrose2528 if they did or didn’t? Prolly didn’t cuz was that slow and they too cool to ask me lol Yes file the bolt hole if need be, just to get it atleast “close”

P08 cam and p08 camgear on a p2j head makes it “half tooth” off or 4.5degrees off adjusting 4.5deg via adjustable camgear = fixes timing but injector phasing is still “off”

Thanks man! Need time to work on a personal sohc but soon for sure hehe

yes sir! with your level of work? the p08 will be amazing after some magical touch from you :)

That’s fine granted ur p2j still uses the p2j cam

Thats what i thought, its just that the distributor is fully advanced but still couldnt hit the timing mark

Well 1 tooth is 9degrees , half tooth is 4.5deg If 16btdc is having the distributor centered ? And full advance can get us up to 22-24btdc And u are maxed at the distributor to see 16 ? It could be a tooth off? or maybe the vms gear is for a z6 like most and you are a Y series so it could be a little off

About damn righhhhhttttt it is! It was maxxd out and cant even reach the 14 mark or even the 12 so that could be it. Vms could’ve been made for a z6, Just a query tho, the mechanical timing cannot alter the setting on the ecu right?

@@elijahcarmona8487 yeah it can’t

thanks man!

The series we are doing now is actually p6fd1 too

yeah i think "links" youtube dont allow but yes mistabone's suggestion was sa correction on lets say d15b7 or ph15 lx (not lxi) saten its half tooth off din vs esi... so to get it correct you do what he says only thing sa p2j / p08 issue i shared on this video is... ok once that is corrected? is the quench distance correct if not then like my esi video? lower comp still made more power... then after that? solution to swirl port for economy? so see after all that its alot better and simpler just slap a whole p08/z6 head right? cuz LFT and even Speedfactory coulda chosen a y8 head na p2j but didnt hmmm

and that is also why i touched up on "distributor" timing is impacted by cam timing... as you see Transzex/mistabone gave valuable inputs and you know locally its always p2j p08 cam mods and camgear dilema (some dont even see whats wrong) but none ever notified possible distributor issue that impacts fuel economy and even performance btw the red lxi i mentioned on the vid? also had 4.7fd lol and natalo pa din 🤣 only found out when it was "for sale" had to declare it to up the value lmfao

Man! tbh im rather excited myself for finding a "reason" ibaba ung engine lmfao! but more importantly Im glad the direction corrects itself like as i read my channel description? it stays true as we know alot changes mood/contents once you know? "pira pira" lmfao Im just glad its helping itself stay on course... as my SRDmotorsports actual shop continues to function and do its usual work? the goal sa channel is like Skunk2's or even Stephan Papadakis' stuff like you continue to race and all but the channel is to share "new" work or just update on whats going on "in-house" which generally for me is just fun x2 lol

right as i came up with that "build series" of my engine? automatically told my colleague "we can dyno on stock p08 intake then re dyno ported p08 intake and finally on ported skunk2" and then final finally ITB loool see? the fun for myself?🤣

@@SRDmotorsports i agree, like KG garage that I follow on here sa YT as well. They get into details of what's going on, even sa driving/how to drag race. Doing it for fun and to help people that are starting pa lang

@@SRDmotorsports It's always fun busting local shop myths and lores hahaha

@@mikodelacruz yes yes i agree! not sure nga if theyre the same "kgbuilt" from ht days but yeah i mean the shop itself is still functioning "normally" here and prolly not this year ulit but next year will def pursue completing the "north series" mostly this year maybe if theres an event in oct/nov/dec will def race or do runs but for now prioritize dyno and in-house developments

Yeah so that’s like a d16y8 so that has the correct cam yes so now just econo flowing ports Once u have it ported or can flow slightly better than a stock p08 head

thaaaaanks bud :)

hahahahaah good point on the wd40 i hope they notice!! hahahahaha thanks man and same i cant wait for March on the new Discovering Slovenia series

@@SRDmotorsports :) Who know, WD is just a Mercedes with almost no opponents. :) Yeah, today is March 1. :)

@@RRRRefuelRideRace yes exactly maybe wd would tell us why advertise? everyone uses us already hahaha

@@SRDmotorsports Would be nice. :)

Oh wait that’s a harder question LOL! Lemme think about that and get back to u in a bit

@@gregypadz9341 same problem, u will never get the cam timing correctly… others think they can fix it by way of adjustable camgear and distributor but u can get the lobe center correct for the engine however your injector firing sequence would be off as it relies on the distributor lets not forget the y8 style head is ECONOMY aka ECONO as its promoting swirl (kaya saliwa ung ports) a US magazine did an article ones… a fully ported vti head done by Alaniz was just a lil bit better than a stock P08 head so if it’s vs a ported p08 head then it’ loses more

On locking vtec… sa pinas it’s often confused and misconception is sagad sa todo lol locking vtec is fine if u have no need for it and it’s a race engine and u got ur main lobes dialed in and the engine design is suited to run best at that… Now locking vtec to MASK a problem that can’t be fixed? that’s mas Malala pa sa stupid if u think about it

@@SRDmotorsports thankyou for the info sir 🫶🏽

@@SRDmotorsports haha ok sir copy that 🤪

@@gregypadz9341 no problem sir! sayang kase a lot of vti or Lxi saten get worst because they do urban legends myth mods pero one vti we rebuilt (may series dito) Did 112whp on stock ecu stock everything pati header stock sa dyno what a stock zc do? 130? Pero nka header na un at nka box… so sayang potential ng vti and Lxi sa totoo lng

Thanks man! Hope this gives more awareness to locals ftw!

Glad and hope it helped! thank you 🙏

Yes sirrr!!! This is free Gold!!! More power to your channel and SRD shop.

Oh thanks so much man! Likewise and stay safe!

a USDM d16y8 is single vtec just like a p08 the main difference is the d16y8 20camlobe the cam timing is correct for a p2j head and distributor that is the issue locally they use a p08 cam when its a Z series like d16z6 and it is off by half a tooth so p08 internals is correct for a p08 head and incorrect for a p2j head a true d16y8 from the US will use the same vti distributor and being "centered" gets you the correct timing on the timing gun

@@SRDmotorsports I bought it from a dude from tatay and I had no idea if it was from japan or US but it has a stamped p2j-4 code. Is it better from the stock p2j local head? And also it had no issue with the stock timing but running it with the stock ecu which was p2m made it like it was hesitant when maintaining speed usually with 2000-3000 rpm. By the way I'm running it with a zc side dipstick block.

@@iancarlosalvador1972 u ran it on ur stock distributor? p2j is head casting so the only difference with a usdm d16y8 is the rocker system and camshaft an adjustable camgear can hide the problem so the timing seems correct... like i stated on the vid if ur injector firing sequence/timing is off? it will run erratic or abnormal... sadly a guy from Taytay pm'd my page asking about such and says they have a whole p08 head but wanna "try" this way forst and i said theyre wasting their time just run the straigjt p08 head... now we dont know if there wasnt a p08 head 🤣 but he didnt have a rechipped ecu so when they ran it? they said it seemed to run out of steal or fuel at 2-3k rpm... odd same? maybe they gave up and just sold it... this was pm's months back u can check... a d16y8 usdm head the cam cap (the cap on top of the rockers) the LMA or lost motion assemblies are tilted slightly forward i mean it is vertical but it tilts forward a bit a p08 d16z6 is straigjt up vertical LMA and u can tell if its a p08 internal converted local vti

@@SRDmotorsports Yes it had an issue but now it was solved by having a chipped and tuned ecu, it was a long and learning journey for me because most mechanics I have asked cannot pin point the main problem. I bought so many parts that didn't need to be replaced 🤣 like fuel pump, injectors, high tension wires and it came to the point that I bought an adjustable fuel regalator, isn't it crazy 🤣. But in the end someone told me that a programmable ecu will solve my problem and that's definitely the answer! At last 😁 The last time i saw the LMA are slightly tilted and are not protruding like the ones with the po8 head. Maybe it's a usdm one. I can relate with your videos, I even done porting and polishing my head before by just watching on youtube. I wish I had watched your videos before but I came out too early 😂 I was using that p2j head since 2018. And had it ported by myself before it was installed. Your videos are great help, keep it up sir!

@@iancarlosalvador1972 aha!! if its slightly tilted then def its a usdm one thats great! and thank you for observing the video and commenting and liking if ever... thays always a big help and all the comments? indirectly sparks new ideas for future content... imagine in the beginning my best thought was just 2-3 vid ideas lol and as the comments go forward , ideas come up and i realize i can do this, share that, share this lol so it does help

The upgrades mentioned still doesn’t fix the issue when u think about it… so most likely a bare p08 head might help better cuz u can turn the adj camgear to time it yes as per belt and crank/pulley relation but the distributor side also moves and throws off the injector timing

@@SRDmotorsports i still have the P08 distributor and will install it. If that will not fix the issue i will find a head right away and take it to you for porting :)

@@Doctorstressmusicchannel do u still have the vti valvetrain and cam? If u do… re installing that can let u afford time as I can see and asses the difference “while” u scout for a p08

thank you!! see even in the car scene "marites" exists 🤣

@@SRDmotorsports hahaha Lol 🤣

Not quite, as the pistons stick out 0.022” or a little more than half mmm and the p2j head has a quench chamber… When I get a chance to make a build series of my Ph16 ESi I will devote all the available specs and measurements of the ph12 pistons and calculate compression on most

@@SRDmotorsports Thanks! That was quick 😅 btw, I have a ph12 engine and planning to convert it to efi. I just saw a ph16 with p2j 20cam lobes for sale, my original plan is just throw a straight po8 head on my ph12 block. Any suggestion on which road should I take?

@@istbreezy don’t get that p2j head as it did what I said not to do on this vid? Maybe that’s why they are selling hahaha Better idea? Get a p08 intake manifold Injectors, rail and throttle iacv etc And esi distributor Turn ur ph12 into an efi ph12 without changing heads

@@SRDmotorsports oh! yeahhh 😅 thanks man! Looking forward on your upcoming vids. Kinda excited to see how much power will it get rebuilding an engine.

@@istbreezy definitely me too!!!

oh thaaaanks whoa nice to know he loves this :)

Double check the engine usually when it’s overheating it’s hard starting or won’t start A lot of times the dash gauge doesn’t show it goes up cuz needle got stuck

@@SRDmotorsports well the gauge go to half way like normal and the fans cycle on and off the thermostat stuck so I took it out have to replace a new one but I don’t think that the issue.. can it be timing?

@@DharamSingh-or3re it could be but if it’s timing then even when cold it should be the same

@@SRDmotorsports ok bro I’ll check it and see but cold it starts fine

@@DharamSingh-or3re alright btw what injector are you using?

Rechipping is done on obd1 ecu only not the vti ecu so the stock one can’t…. Need to get a rechippd ecu + conversion harness to run on the vti

@@SRDmotorsports how much does it usually cost sir? Para di ako mataga. And reco shop sir near san mateo rizal or marikina.

I get all my ecu stuff and work from ECU Later he has an FB… or his personal fb Joel Jasper Enriquez

Also check the VTi rebuild series we did here the white one , had good gains even on stock box

well if ur vti is done like that yeah i think finding a p08 bare head might do wonders for you... cuz it might be harder to find a straigjt vti head but either way both could work well if on tuned ecu

@@SRDmotorsports Can I just transfer may P2j internals to a bare head P08 Head?

@@jmotovlog20 u mean the p2j current that has p08 internals transfer to a bare p08 head? if possible might need line bore on the cam journals but yes definitely possible

@@SRDmotorsports Yes, my P2j Head has P08 internals when I bought the car. It also has d15b block. That's why I can relate so much with this topic 🤣 especially on that camgear issue that take some money and time to be solved 😪

@@jmotovlog20 yes in this case better to find a p08 bare head indeed vs vti

thanks for the question! actually pardon if the video made u feel half hearted on the p08 what i did mean is if its a "whole p08" head then yes good move! not the vti head + p08 internals mod our locals do but on ur case since its an Lxi the main obstacle here is the lxi has a 2 socket ecu so an adapter isnt possible most likely the safest route is bring it to a local shop that wires well like Noli from marcos hwy... so u can run a rechipped ecu because anything on the engine = you would benefit more if nka rechipped ecu na... personally if you would ask me? id choose a rechipped ecu for tuning + port my lxi head that would be good enough plus more fun to see ur vti friends get surprised ur lxi is as fast as them 🤣

@@SRDmotorsports Same situation as ian here. Question is how to find Noli of Marcos Hwy? Or can your shop do this reshipping of the ecu because i would be interested. Thanks!

@@benj_md oh Noli of Marcos hwy is JCauto electrical hold on lemme see if I can scout his link for you guys

Im sure you can but, you might need the vti distributor and other things, is the p2a an lxi head?

I've check in google that p2a is a non vtec head 1.5,my distributor i believe is for vti upon checking on youtube.

@@rhuel3142 oh i see i see

Thanks much.😊

@@rhuel3142 no worries :)

Yes definitely possible

@@SRDmotorsports for now i just don't know what cam gear to use the one on p2a or the one from pm3 head. Hope you can help master. 🙏🏼

@@christopherryanjacobo4746 camgear has to match the head , and the cam of that head

@@SRDmotorsports ow i see. So instead of usung the pm3 cam gear, i should use the p2a cam gear and change the timing belt from 106T to 104T is that right master?

I don’t think the pm3 cam wil fit the p2a head

yeah with the correct camgear setting and tunable ecu excellent na yan and good injector timing

yes on the dsm i kinda remember that... the polyquad is quite decent though migjt be hard for us its also why i knew Endyn knew what was up on their "rollerwave" pistons

​@@SRDmotorsports I just watched the video again and found it nice that you discussed quench. 🍻 Something interesting I remembered 16 years ago from H-T: "With a D16A6 head and D15B2 (flat PM3 pistons coming out of the deck about .028") I ran 87 octane, full timing and as lean as 18:1 air fuel ratio without audible knock in any gear. it was around 10.2:1 compression and I could be in 5th going like 40mph at 1500, hold it in full throttle and still no marbles in a coffee can. it had exceptional low rpm torque." Interesting that he had no part throttle pings (I'm thinking it's due to the additional chamber volume of the A6, but then again I am no automotive engineer but I think Mike B. knew his stuff very well and was TOO's student). Another interesting build was this (except for the bad part throttle pings that they had to drive carefully in stop and go traffic): Y8 head with y7 cam towers and rockers + PG6B pistons with the slight dome milled off + Colt tri flow camshaft; probably the quench pad was too tight Too much of a good thing can really prove to be bad sometimes haha

@@findtherightbeat yes Belben rocked!!!! just he got too fond of his Rottler (boring machine) so it stole some of his attention from engines and more on machining 🤣 on the quench stuff not to say i know more than them but quench distance on paper is never the same in reality like example mls headgasket is 0.037" but in reality wen torqued and compressed its 0.030-0.032 that alone is enough to throw the goal away and ping galore happens but then again too tight is a diff ping... prolly a punch 🤣 but real world have tried 0.040" tight no damage and 13.8:1 no ping on blaze... it happened cuz we ran out of e85 for a month 🤣 same engine than went 12.1 on e85 way back maybe it worked cuz the pr3 head was milled 1.75mm lol making the chambers like a GSR chamber with quench

@@SRDmotorsports Last I checked, Belben works for Glock and is into 4wd crawlers. but real world have tried 0.040" tight no damage and 13.8:1 no ping on blaze... ⬅ Was there anything out of the ordinary or interesting on the datalogs you had for that engine (EGT, etc.)?

@@findtherightbeat not mucj as it wasnt mine :( the engine but it did show -0.1 vaccuum at 114mph hahaha hence i realized we need "moar" lol

thanks so much! for appriciating it man!

@@SRDmotorsports yeah man I learn alot on your channel. I wanted to ask, is it possible to hit 160whp with the stage2 cam(63442)? all other supporting mods taken into consideration

@@vince.r oh definitely i think with today's tunability and tuner's capabilities its definitely reasonable

Then the distributor won’t bolt correct it will be max advance distributor but only 10 timing or 8 And then if full retard it will still be 21 timing Why? Kase the camgear side is still “talon” half tooth

I remember last year someone shared this video in their FB and a local shop was against it and said they know how to make it work? Okay lol Then we find out the customer posted the timeslip after a race and it ran 17.871sec hahahahhaa wow an Avanza is faster lol if that’s correct then a stock vti being faster is wrong?

​@@SRDmotorsportsswap dizzy internals or I believe the d15s will bolt up.

@@--OpT.OuT-- yeah but that doesn’t change the “spot” where the crank trigger sensor is and the sensor that triggers injector? So it gets all too complicated.

@@SRDmotorsports how would anything be different if say your running everything z6 OBD1 except for the bare head. Z6 cam with z6 gear z6 dizzy internals in y8 case OBD1 p28 . Absolutely nothing is changed except for the head casting. Isn't that correct?

Follow up question sir. If mag throttle body ako na 70mm is it okay po? Kasi p2j vtec 16 cam lobes is for economy "vtec-e" mas lean ang setup. Iniisip ko baka sa sobrang laki ng throttle body at lean effect baka bumigay makina. Or is it okay? Just have a proper tuning and it will all be good?

i think this set up makes it unique... Ph15a (lxi) block and p2j vti head pra shang australian d15y5 na wala saten hehe this might work better than converting it wrongly with P08 cam

@@Charlie-uu8so ung sa throttle i think more problem is 70mm maabot ung butas ng iacv eh so inde sha pde but a b16 60mm throttle no problem and yes vti head add mo programmable ecu is big help indeed

Thank you po 😁

@@Charlie-uu8so no worries :) thanks sa comment an feel free to comment again when u got updates :)

Yessss as explained on the video , the p08 is timed different on the distributor end than the p2j and sure u can fix it with an adjustable cam gear but your injectors are still timed incorrectly so if they are charging labor it’s a good move cuz it means ud keep paying 😂 Any chipped Ecu should be good if tuned properly or run the stock p08 ecu on the p08 head but being tuned will be tons better and safer

@@SRDmotorsports My plan before is to use p08 internals on my p2j head (that 6 letter word still on my mind😂). I'm lucky that I've watched your video, whole plan is changed now.

@@maehatano5804 thank you for peeps like you guys :) it makes all the sharing worth it :) Actually the Lxi head is okay naman i think if possible to have it rewired to be able to run a tunable ecu it will do wonders + this lets you run either a y8 vti or p08 d15 intake manifold that would also mean u can switch to a b16 throttle for improved response :) and that might be perfect for an awd

@@PJworks well definitely not the p2j internals P08 head = 20camlobes

​@@SRDmotorsports Hi, I hope you get to still read this. I did get what you meant by the P2J head with P08 internals having issues, your explanations were very eye opening, thanks so much! My question is: I now see some sellers locally selling P2J head with stock 20 camlobes (not P08 internals), maybe this is from a US version (D16Y8 perhaps?)? If that is the case, will this new P2J 20 camlobes version have NO more issues, as presented in the video? Its cam gear looks similar to the local P2J (Civic VTi) and not P08 cam gear Is this version truly "bolt-on"? No issues with stock VTi distributor, timing, head gasket, ECU, etc?

@@King-pv1du yes if it’s a USDM d16y8 head then all the known issues disappear and u use a y8 style camgear or like skunk2 has markings for z6 or y8 but the distributor issue and phasing is all good Only diff now is when u buy let’s say crower stage 2 ? Don’t get the crower 63442z get the 63442Y cuz that’s also the reason why they did two diff cams Sadly locally people sell the y version the 63442y and just says u just adjust the camgear? Sure and it’s back to the same issue I talked about on this video… And u know madami nka ganyan or sellers here and see the results none ran good most even went to Mfactory gearsets and still needed to be feather weight to run decent = ultra slow

Yep :)

It wasn’t the head, it’s what the locals do and try to make it as if it’s a d16y8 by slapping on a z6 camcap/rocker and z6 cam which is called a P08 here… Hence the term “locally” oh and they can dyno but they ran 17.871sec I don’t think we need to see a dyno of a slower than stock civic Again this explanation is for the locals who keep junking stuff by attempting to make a z6 cam and rocker set work on a y5 or y7 it is I think as the d16y8 never came locally just US. sounds like comprehension is needed?

@@SRDmotorsports Quick question, I recently ported a p2j was planning to run d15b vtec cam and gear on A6 block running a p28. You think I'll see much gains over say a factory z6?

It will be fine if the p2j head runs it’s proper cam? Like a p2j / y series cam? I mean in that sense it does work real decent,

@@SRDmotorsports I'm running OBD1, p28 16 degrees timing not 12 plus I'm working with what I got.

@@SRDmotorsports thanks for responding man I watch your videos all the time

Nah man all is good def no problem hehehe I def see where ur coming from… …a little thing to note the head casting has diff angled tangs for the distributor… so to get 16btdc it might be off position , and by then we know the 2 other sensors like cyp and tdc is “off” and that’s the injectors reference point on firing… Def all good questions man… it helps the readers visualize too so you good man
