first off i was wondering if any one could tell me the compression ration of an h22a????? i plan to put this into a 94 hatch.... and boast it... also can any one tell me what is the safest amount of boast i can run through the motor??? without doing internals... and finally what type of transmissions do u guys have on ur motors..? im not sure if u can swap them out like the d and b series motors... kinda new to the h series... i would appricate any help... thank a lot...

 

Compression is 10:1 IIRC. For boost, 10 psi is already pushing it, due to the weak ringlands of the H-series engines in general. You need a heck of a tuner for 10 psi. Something around 6-8 psi is okay for stock internals.

If I remember correctly, F-series trannys and H-series trannys are interchangeable.

All this stuff is in the FAQs link at the top of the page.

 

USDM 10.4:1
JDM 10.6:1
Blue Top JDM 11:1

10psi not even a good tuner could accomplish. I think 8psi is pushing it even with a spot on tune.

 

lol "boast"
"stop boasting about your boast!"
na>boast

correct.

 

so would u suggest changing the transmission out??? to an f-series???

 

depends on how long you like your gears.

you say you're "boasting"....so i assume you want a long geared tranny...in that case an h23 or an f22 trans will be good. the f22 might be a little too long. md23vtec used an h23 tranny on his turbo beast. pm his ***.

but yeah, that's kind of cut and dry basics. do more research dude.

 

thanks for the info guys .... sorry didn't wanna sound retarded or anything but im not gonna lie i dont know **** about the h-series... just thougth i would see how it would work out in my hatch...

 

USDM h22's are 10:1 CR, not 10.4:1.
Regular JDM h22's are 10.6:1.
Type S and SiR S-Spec's are 11:1

That being said, visit the forced induction section of the forum and start reading, search search search, then search some more.

 

10psi should be fine on a stock motor as long as u have a good tune

haha I highly disagree. well depending if its basic greddy, fmax, drag t3/t4 kit. I have seen upwards of 14 psi. Not saying its the safest thing but it definatly can work .

don't be such a women, i have been boosting 11psi on stock honda pistons at 9:! c/r for 2 years. everything is A-ok

 

i dont feel like starting a new thread for this cause its a simple question, but while we are on the subject of h22 internals, im buying an h22a4 block off a friend for cheap, just needs new pistons. Im just gonna put stock pistons back in it for now till i save up enough money for the boast i wanna run, but do all non-pistons from 92-00 work?
