Ill start off first by introducing myself, I am Max and currently building a boosted H22. That will be going into a 95 Civic EX.
First thing I have to find out is if my wiring harness that came from the importer is going to work.. Since some things are cut. Here are pics. ( Notice there is a a pigtail that is cut off... Inside the covering there is, I would say about 200 wires. They seem to be after the firewall grommet so they would be inside the vehicle. What are they for? Will this harness work in the car?




Now back to the engine... Its a 92-95 OBD1 H22a. The list I have ordered or parts at my house.

Eagle rods and pistons (9.0 Comp)
Skunk2 Valve Springs and Retainers
Crower Stage 2 cams w/ skunk2 cam gears
Skunk2 Intake manifold w/ Skunk2 68mm TB
880cc Injectors
AEM Fuel Rail
2- 255lph Walboro Fuel Pumps
Hasport H22-95 civic mounts
Koyo Radiator
Stage 2 axles

Now this is where your help would be much appreciated...What else do I need?

ECU= Hondata?
And anything else ill need PLEASE LET ME KNOW!

 

now i dont know much about turboing cause im more of a NA type of guy but you might need the engine sleeved depending on how many psi your going to boost. but yes tuning is very very crucial if your going to boost. after the engine is put all together i would drive that thing like a baby to the tuner shop cause you might really hurt the car running with the stock ecu.

 

Oh yes I know how crucial tuning is (had a boosted rsx type-s). Yes that was another thing I was wondering.... for 14-16psi of boost with LOW comp pistons.. is it a need to sleeve? It wont be driven untill on dyno being tuned.

 

Might want to resize your pictures. Cool project.

 

No one? PLz need help.

do you know what kind of pistons you'll be using? the h22's have a different material used for the cylinder walls. you can research in the prelude forum, hyrbrid forum, FI forum. but with 14-16 i think you'll need to resleeve it.

 

i didnt see a car ut cool ecu

H22s have carbon reinforced sleeves, not friendly for 14-16psi. You are going to need to get re-sleeved if that is what your aiming for. If your gonna go this far with a build, the reliability and piece of mind is worth the extra money to be bulletproof. I see you wanna turbo the H22 which is fine, but your definitely using the wrong cams. Most aftermarket cams have too much overlap and while that is ok for NA applications because it lets the motor breathe, on your turbo application the pressurized air will push right around the exhaust valve, resulting in lost cylinder pressure. I believe your best bet for boosted cam choice would be the JDM Type S cams. I am not an H22 guru, but I know just like most people that in a B-series the most common and best power producing cam is the Type R variants. I would suspect the Type S cam would be similiar. Perhaps someone with boosted H powered cars can chime in on this. Also why on earth are you using 2 255lph walbros?? One should suffice for whatever your trying to go for. 1 Walbro 255lph is capable of supporting 500-550whp. You have not said one word about turbo selection, but if your trying to be in the 14-16psi I am guessing your looking at the GT28RS because that turbo is most often in it's sweetspot with that pressure, depending on application. I think you should post what your trying to achieve instead of trying to throw together some combo that is most likely not going to do much but be a drain on your wallet and leave you with less than desirable results.

This is a link to a relatively local and well known tuner in PA, there are the H-powered dyno charts he has posted up on turbo setups. In one article he mentions that H22s are very restricted in the intake manifold/throttle body/cam area, he suggested the Skunk2 70mm throttle body, Skunk2 intake manifold, and Skunk2 stage1 camshaft, I see you have stage2 so maybe you should contact him further about using those cams, or flipping them to someone else and going with stage 1s. Also of note are the log manifolds are something to stay away from as well. There is a lot of power to be madeup with an EL style manifold. Just thought I would try to clear up an errs on my part. Don't wanna spread any wrong information like half the douchesilos on this site.
