MPFI Complete Dyno Runs - 88-91 Civic & CRX 

So what do you all think of the MPFI gains!?!

This was the best series I've ever seen. I suck at wiring, I mean I am terrible but the way this was explained I really feel like I can do it my self

Great swap guide , lots of valuable information makes me a lil more comfortable about doing my swap

Rite on!!!!! Totally worth the effort!!! Such a dope series, I love it!!!! Still cruising the older videos :)

Another cool addition to your channel Jon. I appreciate the detail and the split screen comparison you did to show us the difference in performance from the manifold swap. Awesome! It'll be interesting to see what kind of improvements the future intake and exhaust mods will bring when you dyno it again.

This is an amazing channel for any Honda fan! I dig knowing that there are others like me, 96 Accord EX Was my first car and I still have one.

Just wanted to say Still loving the channel and enjoying the content! You give off such good vibes! This is one of the only channels I try to keep up with!

Good job John,so happy it all worked out.time to get my wagovan back on the road! keep up the great work! 👍✌

don't see too many videos like this about the good Ole manifold swap, none at all to be honest. great video man once again!

Great looking cars!! I fell upon your channel because of your toyota pickup lowering DIY. I am in the market to maybe buy one as a daily. But I really gotta give you props on the amazing job you do on all your cars. The attention to detail on the small things is awesome. I love these little cheap cars that will really run forever if you just give them a little attention. There is something so satisfying with making all the little things work properly and then making little subtle mods to make to make the car look so much better. Thumbs up to you!!

Awesome, just finished a rear disc swap on my 91 sedan and waiting on parts for my own mpfi conversion. This series has really got me amped for the result.

Wow! This was SUPER interesting, and encouraging, too! I cannot believe the mileage on your car! And, to think that it still makes just as much power as it did when new, this is incredible. I doubt that any modern car -- 26 years from now -- will be able to brag the same way. Honda of the 90s, TRULY built incredibly reliable machines, that also are a riot of fun to drive. Truth be told, I feel relieved and foolish after watching this video. See, I have just a tick over 100,000 on my '91 Si. Everyone around me says that this is low, "for its age." Next to YOUR mileage, though, it has me thinking that this engine of mine is still just a baby, with lots and lots of life still left in it. It'll probably outlast *me*. (I keep on top of all maintenance, and I use only synthetic oil. I will be switching to synthetic Rotella T6 at my next oil change, so I expect to enjoy many more years of motoring.) That's the relief part of the equation. I feel foolish, when I think that I was worried about how much more life I have in this D16A6. Haha. I didn't need to worry at all, it would seem. I am learning so much about my car, thanks to you, Jon. I will continue to eat up any videos you post in the future.

All week waiting for this video, very good video, greetings from spain

Your doing it right...back to factory, then explore as you gently mod "up", baby steps and have fun!

another great video Jon your the madman!!!

hell yeah man good to see vids again..

Another great vid

Man ur videos are tip top. From GA!

And this is why I only get notifications from your channel.

I know its an old video, but im about to be doing a d16a6 swap in my hatch. All that I've got to get is a distributor and then do it all. my poor d15b2 was already low on power and it finally decided to let go. But honestly this video series helped a ton in figuring out everything that i needed. But i ended up getting an si harness too instead of extending all the wires

Your my favorite RU-vidr. Keep it up man

just picked up a 90 4door. with the same set up. fun lil car.

hey, i love watching your videos because i have an ef hatch as well. i have a parasitic power drain, and i'm not sure how to diagnose the issue.. I've replaced the door switches that control the dome light but that's about it. thanks!

Man,Honda has so many different engine setups and variations it's crazy. They're all over the place with part numbers like PR3,PR4,PM7,PM6,P08,PLC,....I sell auto parts in Jamaica so it's been cool learning the various part numbers from different Japanese makes especially Honda. Theirs is very logical and they make it easy to get items like head gaskets,water pumps and timing belts. As I'm sure you've come across all sorts of technicalities with these. It's fascinating though.

that's 1 clean wago. mpfi is the way to go.

thanks

the only dpfi to mpfi that actually shows how to wire. i gonna start mine but im going odb1 with a z6 head wish me luck

Damn wish you had this up last year when I was doing my MPFI swap. :) I went obd1 because I had all of the parts I needed sadly I still have a check engine light on for my O2 heater... Awesome video's Jon keep up the good work!

The best dpfi to mpfi video or write-up on the the internet bro great series!! Always enjoy your videos man. btw is there any reason your not running the traklites on your track car? I just grabbed a set of Traklite Gears 15x7 in arctic white for my ED Sedan was wandering how you like em??

Nice series, seems like it gained a lot of drivability.

This was totally sick man! I guess that means that on a good day you're making over 100hp to the crank, my 2006 Scion xB makes an astounding 82whp! And it's heavier than your wago as well, so nice

Need some videos on that Toyota Mini Truck, Subscribed!

At the end of the day, the dyno just measures peak power numbers. The 0-60 definitely got quicker and it pulls stronger with the mpfi.. merging on the freeway is less dangerous now with more pep

Fun pr4 fact i got from HT a long time ago when i LS swapped my ef: The 90 PR4 (PR4-A01, A02, L01, L02) integra ECU and the 91 PR4 (PR4-A10, A60, L10, L60) is that the 90 version has an external PA sensor and the 91 version has an internal PA sensor. I forgot which year ecu i used to make my ef run better lol

hope you can help me on my wagon 1991 b20 swap I'm getting rich on gas plus my temperature needle is not working I would like to know the wiring diagram for temperature sensors and fan switch thanks so much and you have already helped me with the distributor harness thanks for your videos !!!

jon im so waiting on u to drop a b20vtec into one of ur 4th gens!

That was a fun video! I'm not sure about a 2.5" exhaust though. Wouldn't that effect the scavenging too much of the post combustion?

hey Jon what transmission are you running . there's a cable transmission with a shorter gear that would help. and the d16y8 intake manifold would help with power also

Love watching your videos bro and subscribed to your channel. From Texas Also! 1 question how you hitting those rpm's with that stock B2? I have a fresh stock reman B2 in my Ef and I'd be afraid to go past 4000 bone stock including the exhaust mani

i know what you mean about working alot i got a job and i own a buisness nothin but work but in my spare time been tryna get wago going strong and your vids help tons. you do good detail vids and you have fun in between. cant learn this kinda stuff on haggatd garage.

I'd like to see how much more hp your wagovan would make with an exhaust intake and retune. I miss my old ex sedan EF I got lucky and it had the MPFI from the factory. I recently put a short ram on my ek to me it feels like it made a difference in response it use to lag alot before the short ram helped it. How much did the dyno tune run you?

Loved when everyone got all excited at the dyno that shit was so funny! What camera are you using?

So glad you posted the dyno results cuz now im going straight to a high comp b20 instead of wasting my time with the manifold swap.

Instead of an MPFI swap, I put a Weber 32/36 on the DPFI manifold (I milled out the plenum to accommodate the airflow of a 2 barrel), used a 1984 civic distributor, and I chopped out my ECU. It blows the DPFI setup out of the water, and it is pretty competitive to the MPFI swap, even with my 4 speed.

i would have liked to see if there was any power difference between the pm6 and pr4

U need to replace that AC with a universal parallel flow condenser because R134 was design to work with parallel flow. The condenser u have will definitely give u high head pressure when it 80-100 degrees outside, and it will not get cold after 100 degrees. If u had a PFC Condenser your AC will get super cold even when its 105 degrees outside. FYI the bigger the better.

Hello Jon! I'm from Moldova, I have a Civic ED6 with d15b2 DPFI. I have the opportunity to put a D15Z6, will I encounter more obstacles considering it is with VTEC? Or is it better to leave the old D15b2 block with the L3 gearbox and put only the cylinder head from the d15z6 with the intake and the ECU d15z6? I'll have to pull cable for VTEC ... Thanks buddy! You're doing good videos!

awesome, I've been curious about the gains made for a long time. makes me reconsider spending the time to mpfi my daily ef. one thing I'd suggest is maybe 2 1/4 exhaust, 2.5" is pretty overkill for a lower rpm non-vtec and sohc. Might hurt the low/mid rpm power.

would an exhaust and intake take it to 100+

nice gains! it would've been interesting to see the dyno difference between the 2 ecu's tho, there must be something different about it And you want to do a short ram air intake, but if you drive in hot weather that might get you less power, since the car already dropped a bit when it was hotter with the airbox, maybe it might be a good idea to get a quality air filter for the oem airbox ? because the short ram will only be getting warm air from the engine bay, unless you build your own airbox with ducts and stuff ? I wonder what the result is going to be :D great vids bro !

hello friend greetings from mexico I have a doubt that car is the multiple of admiration? and what parts did you occupy to bring the convergence? I'm interested in doing the same to my ef

Hey Jon, I was watching your series, and I was wondering if you have a parts list somewhere so I know what i need to do this swap?

I just watch this whole series and my only problem is would this whole conversion work on a lx automatic or no because I really wanna do this to my car been rewatching videos but idk if I can do it with my automatic car please get back to me

i have a 1988 wagon i need to do this conversion and also a stick conversion as well i have a 4door ef that was also auto but converted to stick can i just use same stuff to fit my wagon?

Hey bro can you do a video on how to replace a timing belt, tensioner and oil seals. Thanks.

still no honda but still great, cheers

I have a 90 wagon and my turn signals will not work at all fuses are good only thing I could think is the switch do you have any info on this subject

so was this off of another D15 or D16? I am trying to do this to my 91 civic hatch.

Hey Jon I was wondering if you could she'd come light on my problem. I bought an eg8 the engine was swapped with a D15b2 and has a MPFI swap as well. Only problem with mine is the car runs at about 1500 RPM and runs super rich. But other than that runs good. Do you have any idea what to look for on what could be the culprit? Thank you in advance. The new channel name is awesome

Jon, I've watched this build series a plethora of times and I believe I am ready to take on the conversion myself, only problem is parts for these cars around here or the "ef" are very hard to come by(I'm the only guy in town with ef). I had one chance to meet up with some sketchy dude off our most local honda page, and the stuff he wanted to sell me weren't even for an ef... on the same note, I love watching your scrap/junkyard vid's! If I seen them cars at my junkyard I'd faint literally. Basically my question to you is would you ever be down to sell me multi point stuff for my sedan??? P.s. absolutely sick video series, they inspired me to try it on mine!

+Garage Built Hondas I'm working on swap a 98 B18b1 acura integra engine into my 94 Honda civic DX coupe. both are automatic setups. I heard that is a plug and play swap. but my question is; do I have to do some re-pin at the passenger side shock tower plugs? or is totally a plug & play swap.. I want to keep it OBD1

I want to do this to my wagon. How much do you think the total conversion would cost?

Could I just a SI harness, manifold, distributor, and ecu. I not comfortable doing that much wiring.

Hey man, recently a few of my coolant lines on my dpfi decided to give out and ripped. Have been considering this mpfi swap but have an auto 90 Civic LX sedan, just wanted to know if I do decide to give this swap a shot would I need a different ecu?

I have a pr3 on my 91 civic and it idles at 2000 rpms then drops to around 1500 rmps. Still trying to figure out why it idles so high. Awesome channel by the way, always watching your vids.

need help finding a video on chipping a obd0 pm9 ecu anyone???

did you have any issues upon first start up?? I did the swap to my 89 dx hatch it started like 5 times but i had to keep the gas pedal on the floor to keep it running. but now it wont start again. it just cranks and cranks

How is the D15B7 rated at 102hp stock? B2 should be 90hp.

you should do a 1/4 mile run, im very curious

hey man I’m having a fuel issue with my civic wagon that I’m doing a mini me swap on. it was originally dpfi so in addition to the vtec head swap I’m doing an obd0 to obd1 conversion with the dpfi to mpfi. I’ve got the p28 ecu, bought a jumper harness and got everything swapped and plugged in. It’ll crank and start for a second but lacks fuel and dies. the fuel pump primes when I turn on the key. just can’t figure out why the fuel pump won’t turn on with the car

I need to get another wagon ASAP :(

How the I make my Honda Civic 91 lx more horse power

how did you get those ecu , s to rev so high in between gears

can a obd0 pm9 ecu be chipped

oh just wandering have you seen the boostedboiz channel?

Throw an A6 cam in there with a Y8 gear.

Hi, question did you get better mpg or worse?

hey what's up I got 89 dx I'm looking to do the same but watching most of your dpfi to mpfi and others I'm really scared to touch anything as far as wiring but I've pretty did mostly everything to since I had it

are you selling any of your cars?

Is there a big mileage difference?

time to swap in a a6 cam

Por dicha vi todos los vídeos hasta el final. No podría invertir tanto tiempo y dinero para ganar tan solo 10 HP en comparación con el Dual Point, el D15B2 tiene 80 HP stock. Es preferible tener el motor original en óptimas condiciones, poner un buen intake de alto flujo y un buen exhaust de alto flujo, les aseguro que gana igual o más caballaje.

MPFI swap is always great, but 91hp is not that impressive number. What about making video series on a Z6 head swap?

now put a JRSC (10 psi) and some water injection :)

pr4 ecu map is for an LS b18a by using it to run a d15 it is running too rich for the fuel map that the d15 needs, same deal goes for the b20 except it's going to run lean, both of which will cause excessive heat in cylinders and potential for detonation also higher carbon build-up, for d15b2 engine you'll need a pm5 or p04 ecu, get your HP and TQ back to the 92hp/88tq it should be there's a vid on my channel of my d15b7 with a z6 head vs a Mustang GT my vid shows how a single jingle is supposed to run here it is : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qBm0BgXKgrI.html

Can you sell me a mpfi kit for my 89 civic dx hatch

I made 115 with my dpfi. You had to have had something else wrong maybe

What rim and tire size do you have in your ef?
