Jdm H22a Turbo, no power
Yes i have stock internals and cant afford the other stuff yet bla,blal,bla.. but shouldn't this motor pump out more power than 230 crank hp at 8 psi before it knocks on 98 octane pumpgas?
I really tought that this setup should do 300whp+ well tuned but it didnt.
Civic 96 EK
92 h22a jdm prelude
525 inj
255 walbro pump
t3/t4 to4e turbo
3" downpipe, the rest is 2,5"
no bigger leaks
Aem ems
My tuner is good, but not very known with either honda or AEM. He said probably to high compression..
Im trying to solve the problem and i know if it's not the compression, it can be allot of other issues. Anyway, something is restricting it heavly,
-Is it my compression that's way to high? it reads around 230psi. hope its that easy.
-My next thought is that the AEM EMS is reading some wrong values or restricts it somehow, im not very known with the sytem either, temprature shows 205f on ems and the water that exits the motor reads 190f on external sensor, stock dasbord gauge is aslo at normal levels, so tempratur "should" be good.
o2 sensor on AEMpro is red.
-wrong startup calibration? the one we started with was from a prelude 96 h22a
-bad turbo?
I hope someones has an idea of what it might be, im out...
I'll sure post this in the EMS Form to..

Re: Jdm H22a Turbo, no power
You should be in the 300 whp ballpark with your setup @8-10 psi. You'll see a wide spread on claimed hp due to dyno and correction factor differences but it sounds like something is off on your setup. You definitely shouldn't be getting any knocking @ 8psi on 98 octane. I'm running 10:1 and am around 545 @ 23psi. (sleeved, Arias pistons)
Ringlands are the weak link on stock h22s but with proper tuning 300 hp+ shouldn't be a problem. Under acceleration AFRs should be in the 11.0 - 11.5 range and timing should be dialed back. Good luck.
