D17a2 y8 intake manifold swap info 

I really dont see how this would be a performance upgrade, the y8s ports are different shape.

@@slowazzes1972 on the exhaust side yes, the intake side is exactly the same. The airflow is also way more direct than the stock manifold that comes the y8. The flanges are different that's about it

If they were any different then this wouldn't work at all. The exhaust ports are different yes, the intake ports are not. I actually have both heads in my garage right now and can confirm this. The flanges and gaskets are different because of the y8's bolt pattern and the d17's age chamber, you just have to modify 2 holes on the flange by extending them by maybe 1/4 of an inch and making the coolant port on the manifold work as the new egr chamber. It does work as a performance mod the airflow is more direct and doesn't have to travel as far. The rpms don't hang after shifting gear and the overall throttle response is better. If this wasn't a performance mod for the d17 then so many people wouldn't have done this to them in the first place. This has been a must do thing for d17's for so long you have articles on forums that go back more than 15 years about this specifically. This is one of the first mods anyone's ever done to the d17 its even been thing for so long its featured in articles on how to make the engine perform better. How have you not heard of this and why are you acting like you know shit?

Keng Vang were you from?

RudyborjaEM2 I’m from Minnesota. Lol

RudyborjaEM2 you still make them? Need one

@@ADM1TGAMING yes I do. Email me at rudyborja1981@gmail.com or hit me up on Facebook messenger Rodolfo Borja

You block off the y8 iacv holes with screws and lock tight. Then use a tb from a y8 automatic or d17 tb or k20 tb...in order to use d17 you need to mod 3 bolt holes and port match the tb. Using k20 tb only need to mod 1 bolt hole and port match the tb. The automatic y8 tb bolts on, not port matching...now you can also go another route. Using the manual tb from the y8, you add a hose to the y8 intake manifold vaccum port and you match a flat metal plate with 2 fitting hoses where you can bolt on a d17 iacv and wala

RudyborjaEM2 I have a 2003 Honda Civic EX and it's leaking water through the intake manifold what can that be

Email me at rudyborja626@gmail.com What injectors are you using, what tps are you using, what throttle body are you using, is the map sensor sealed right, is the iat sensor on, what manifold gasket are you using??? Email me so we can possibly meet on the weekend. I stay at south el monte

rudy simple questions 1 do i use a y8 intake mani gasket 2 do I use y8tb gaskt or d17 tb gasket

Austin K email me at rudyborja1981@gmail.com your probably using the wrong cable bracket

Those 2 line are coolant lines. Its function is to warm up the throttle body for below freezing temperatures. So i live in California. I dont need coolant getting my throttle body hot. So I can plug up the lines or just connect them together

ah so i can just connect them how it supossed to be?

RudyborjaEM2 you reckon this will work with d16w7 ep2 let me no half way thru

Joe Gent not sure whats engine is a d16w7

RudyborjaEM2 it's ep2 1.6 5 door model identical to this have a look it's d16w7 is an e vtec

Joe Gent ok then, if its identical to this engine, the y8 intake manifold swap should work as well. but you still need to mod intake manifold

RudyborjaEM2 yes modded the inlet manifold had to drill and tap the metal and possibly change the fuel injectors .

beastlierect95 you need to switch the two outside wire of the tps. Leave the middle wire.

beastlierect95 email me if you still can't figure it out.... rudyborja1981@gmail.com

RudyborjaEM2 can you help me I have done this with k24 tb starts but won't idle I can rev it though

@@bratt4478 $100 to modify it...$200 to install it

Technically yes you would pass smog but there's two phases on the smog there's also a visual inspection all depends on the smog person if they like you or no if the guy knows that car comes with a plastic manifold you will not pass you but if he doesn't he will pass you on small grills in Cali you have to put the same year of your car or newer parts so you can't go backwards on Old parts but not everybody knows about cars like we do they might not catch the manifold difference because the single cam and they all come with it or he might know that that was supposed to come with the plastic manifold I'm currently voice texting because I'm driving hope everything sounds okay without commas and periods

Ive got a friend that can look past visual but not the cel

@@daltonjmurdock no cel

So do you use the d16 gasket or the d17

@@daltonjmurdock yes I use d16y8 gasket but the paper gasket not the metal gasket. Because you need to mod the gasket a little for the egr port

you need your mechanic to whats this video and others video's other people have done and Google it....on Facebook ask the 7th gen civic guys for the links

corbin parvin you can leave it stock or use the return system

D16 injector intake manifold stock rings and added hardware o-ring...Whatever seals....take the injectors with the manifold to fine what works

And make a bracket to hold fuel rail from moving

you need to modify the y8 intake manifold to fit

Cody Fritsche doesn't matter

RudyborjaEM2 cool thank you

RudyborjaEM2 so you can put this on an automatic?...

it does make a difference. the high flow, d16 flows way better than the d17. the d17 has too many loops and turn before entering the head....the d16y8 is known for the best d series stock intake manifold flow. the throttle response feels better....if you just have intake you notice very little...if you have alot of mods like me upgraded cam and ect... you'll notice a bigger difference.

@@RudyborjaEM2 very late here but I wanted to ask a question since you mentioned on a stock engine it's not gonna do much except improve throttle response so my question is my car has a 4-1 header and a complete aftermarket exhaust system without the catlytic converter so is it worth it for me doing all of this I wanted to do this a long time ago but I live in a country where is very dusty so aftermarket air intake systems are not a option as they suck in quite alot of dust as comapred to factory airbox but since I have another car now and don't drive the civic on daily basis I will put a aftermarket intake on it now but will the mods I have compliment the manifold in making any power or it's not worth it?

@@FB6K24Z7 its worth it. But buy the k&n intake filter. There washable. And don't drive in dust storms. The K&N filter clean sells separately

your not going to use those, just cap them off...email me a picture...rudyborja1981@gmail.com

corbin parvin i use the d16y8 intake manifold gasket....if you wanna buy the thermo gasket, buy the d17 one

when I first install the k20a3 si or rsx base model 270cc injectors, I had a fuel return system so i adjusted my fuel pressure low at 25 psi or 30 psi with the fuel regular and running stock ecu...but I had a air/fuel ratio gauge to help me...now I got the k20 after market injectors FIC 650cc with the Kpro ecu

+RudyborjaEM2 I switched back to stock injectors and now my idle is jumping up and down is it because I don't have coolant running through the iac valve ?

+Austin K I forgot to cap off the extra port on the egr outlet

well I'm using stock d16y8 bare intake manifold and the fuel rail, injectors, regulator and fuel lines....im using all the stock d17a2 sensors and throttle body except for injectors...but you can use your stock d17a2 fuel rail and injectors, instead of you d16y8 fuel rail and injectors

I'm currently using the stock k20 throttle body...

+RudyborjaEM2 excellent! thank you. also, can this be done using the automatic y8 manifold? or do you have to use the 5spd? perhaps it doesnt matter?

+Marshall McGaughey it's actually better to use the automatic one, because of the hole on the back...5 speed has a hole for the IACV. d16y8 automatic has no hole and the IACV is on the throttle body.

lo puedes encontrar en un gonke...el carro civic ex 1996-2000 tiene el y8 maniful...lo necesitas que modificar

y esta dificil, que mas arreglos tengo que hacerle aparte del cambio del manifold

+benjamin lopez pues los hoyos para los tornillos los nesecitas modificar en los dos lados....se usan todos los sensores del d17

Nicolas Dujardin should be the same

$300 plus shipping?$25?....$100 for install . I live in USA California in L.A.

soundsi like a good deal, you post it on eBay ?

Chris Coonjah yes I post on eBay, only when your ready I'll post

craigslist lol

it go by the intake manifold craigslist or junk yards. if you want to buy it already modified that cost from 175 to 300 but you want to hit me up if you're interested

D16y8 gaskets for intake manifold and throttle body or if you go k20 then k20 gasket

RudyborjaEM2 thanks bro i had another question, Yo rudy what about the coolant line coming from underneath the intake manifold its a bronze like tube with a rubber smaller hose with coolant but do i put it with a tee to the thermostat housing going to the back of the manifold

@@DEATHVALLEY_915 email me rudyborja1981@gmail.com or hit me up on Facebook messenger Rodolfo Borja

RudyborjaEM2 im lookin for you on fb but alot of people come out with your name

RudyborjaEM2 what does your profile picture look like b my name of fb is Sirr Christopher Montana

Google shopping, on ebay, craigslist, crower.com

melbatoast1985 yes you can, just buy k tuned top hats for injectors and plug the return line or put a fuel gauge on it.....email me for a picture.....rudyborja1981@gmail.com

thanks bud it just seems simple enough and the manifold online is like 35 bucks so why not right, if using a larger throttle body would you bore out the inlet of the manifold or will it make a difference? like an 75mm b18 TB?

melbatoast1985 70 or 72 is the biggest you can go on a stock d16y8 intake manifold and skunk2 intake manifold 72-74mm....I don't think they make 75mm

melbatoast1985 you will lose power if you go too big on tb if you got no cam or port and polish

sorry i meant the 72mm but yea i'm not much for making videos on my car and my car was only made for canada anyway so i think people would get confused why my "civic" has an acura logo on it. although i did make a short film. watch it comment and like it lol any way when i got the parts together i'll post a video and keep ya posted.

Not really....I rarely get ramdom missfire like once every 3-4 months

I didn't delete the egr, its still functional...if you delete egr you need Kpro or AEM ecu

thanks, i started to create my own one with all of your informations, i'm from france and we have different y8 manifold with differents holes, when my em2 start if it works i'm gonna upload a video :)

RudyborjaEM2 i finished my y8 manifold, you can see my work here www.japancar.fr/forum/Sujet-Em2-MK2-Photos-p3-Retour-a-la-maison?page=3 it works perfect, i just using different holes because we have different y8 manifold in europe ; )

PWNED good job. Im on Facebook Rodolfo Borja and there's a 7th gen society....subscribe me im going to make a new video soon

thanks alot ;)

You can but you need to be tuned. You can use the d17 injectors with stock d16y8 fuel rail with top hats and the fuel regulator plugged or use a fuel guage in place of plug

RudyborjaEM2 thanks dude. I have a 04 es1 auto working on finding a 04-05 ex as a parts car so i can manual swap. I got a buddy whos gonna get me a y8 manifold

You also need the subframe from a manual car and axles

RudyborjaEM2 i know i have read the forums, thats why i was gonna get a complete car for parts instead of trying to junkyard part it

5-15hp and it depends on what other mod you got done to your engine

Yes you can do this swap on automatic D17

it depends if your mechanically inclined power tools are necessary

the map is on the k20z1 throttle body but when you run the stock d17 throttle body the map will be located on the back of the y8 intake manifold where the y8 iacv hole is located

explain your self better a2? d17a2? You mean for vtec?

Seriously just you basic bolt on and you add the y8 intake manifold swap with stock throttle body like 5 hp...now the d17a1 has no vtec and has 115hp. Now the d17a2 witch has vtec has 127hp. No now you subtract 127hp vtec -115hp non vtec =12hp vtec gain serious no pedo. Now you can get more power just like any other car does by adding more performance parts like cam or pistons ect...I installed the Skunk2 intake manifold from the 92 thru 00 honda civic single cams. Now just like the d16y8 gains when they add the skunk2 intake manifold, the d17 will gain as well seriously.

RudyborjaEM2 so to add more vtecs go after Wisco pistons + rods assuming? Skunk2 y8 is better than just a y8 stock from a d16? ( also I have a2) also 7th gen I drive the 04 civic ex

@@1800BusterCheeks any performance part is better than the stock part. If you're doing pistons and rods you got to know what you're going to do are you going to go and they are you going to go boost once you figure that out you know what type of Pistons to get it doesn't add more VTEC it has more power

@@1800BusterCheeks email me if you have more questions rudyborja1981@gmail.com

RudyborjaEM2 I get yah that yah can’t add more VTech unless u swap the synchro’s? ( assuming ) and still unclear about that but the things u add just add power such as for starters real cold air not ram air full exhaust headers cam lifters rods pistons ect... definitely saving the email if I send ??? I’ll label them as Honda 7th gen or something along the lines.. I just been recently hitting junk yards and had happen to stumble on this

It would fail the visual inspection.

honestly d17 injectors with stock fuel, you need to add o-rings and Mickey mouse a bracket to hold it in place....I like better stock d16y8 fuel rail with d17 injectors with k-tune top hats and d16y8 o-rings, this way fuel rail bolts straight ups.

+RudyborjaEM2 haha mine has been running running rich for some reason even though I replaced the Map, coolant temperature sensor ,air intake temp and the o2 sensor and I've been getting like 22mpg so I've been thinking about doing a y8 throttle body swap to add more flow . what are your fuel trims and what's your gas mileage

+nope nope my fuel trim is stock with stock ex ecu and if I really religiously go 65-70 on the freeway I gotten 39mpg 400-450 miles on a 11.2 gallons one fill tank

+nope nope check your thermostat and clean your throttle body...where does your car idle at? rpm...you might have a vacuum leak

RudyborjaEM2 do you have a stock exhaust?

is it easy to install????? and how much hp gain are we talking about????

I've only seen guys in Thailand use y8 tb...I've used both d17 and the k20 tb before....y8 is 56 mm, d17 is 57mm and k20 is 66 mm...if you want to try the y8 tb, you would need to use the automatic y8 tb, because the idle air control valve is on the tb like the d17 and you will need to switch some wires around on tps and map maybe

Oh ok ill just keep it simple

RudyborjaEM2 You still sell them ?

No its easy...its a bitch to fit the skunk2 intake manifold on witch I currently have on right now.

Did you have to move that brake line , the hose fitting that's for the egr keep hitting it

+Austin K you just push back the AC line and the power steering line bending them back a little bit and you're good

+RudyborjaEM2 and I just made a new gasket out of cork do you think that is good enough, why do people advise against using the y8 gasket it seems like its better because it's thicker and transfers less heat

+Austin K I always use the y8 gasket. it matches up with Y8 intake manifold better then the d17.

you just remove all nuts and bolts, don't for get to remove the two bottom brackets...btw you need a racket wrench 12 mm...it's really easy

RudyborjaEM2 is hard i was trying today to remove it because i m doing head gasket on my ex 2002 the nuts is hard to remove no space for nothing omg all ready remove the 3 bolts fron the batton brakets

+pavel1809 go buy a ratchet wrench 12mm

RudyborjaEM2 all ready have tools

thank you for you help i ready remove it

yes
