I was wondering how reliable a turboed h22? I would think its not very. 5psi on that motor. I would think about maybe 300 at fly. With good tuning and every thing so still my car will out perform it until the end my 8 valve head will flow about 350 hp before need bigger valves. If i spent the money and time on 16 valve conversion shiti dont even wnat to talk about the number possible...

 

what?

a h22 can take 7-9psi no problem. Assuming you dont dog it keep it maintained.

 

From the information that I have gathered, H22 tend to have weaker rings.

 

not sure if it makes a difference. but depending on the year h22 as well. 93-95? or 96? cant remember. they were closed deck. might help in a turbo application.

 

A turbo H22 will kick your car in the face. H22s take to boost very well.

 

man, ive heard both sides of the story.....h22s are good for turbo, h22s suck for turbo.......


give it a shot and let us know how it works out for you..........

 

turbo ludes

 

Actually, from the information that I have gathered, the H22 dont take to boost all that great. They seem to have weaker ring lands and the rods arent that strong with pressure. Also, the cyclinder walls are thinner that the B series motor

 

for reference.. here is a list of everyone who has donated info to preludeonline.com. a spreadsheet of Who's motor has blown. and who's has not blown, their setup, and what died.::::

21. marksaccord95 8psi, turbo, hondata
22. bluluder 7psi, turbo
23. ummm yea 7.5psi, turbo, mf2, 8.5:1 cr

its almost 50/50 most likely due to driver error, etc etc. just gotta the standard precautions.

 

and ya. your correct abotu the ring lands. but thats mostly due to Detonation, pistons would fix this (aftermarket). but as you see, ppl w/ the J&S or other precautionarys havnet blown.
