I'm saving up to an H22 or H22 type-s for my hatchback si. and it will be turbo'd. Can someone tell me the ups and downs of both motors if I were to go turbo and what you think I should do?

 

type s is a waste of money if you want to go turbo. with fi, you want lower compression, not higher (usdm h22 = 10:1, jdm h22=10.6:1, type s=11:1).

So which is it?

 

if you did run just NA, the higher comp. but since you are going to turbo that **** you wanto lower the comp some but not to much like down to 10:1 witch would be fine then run about ~8+ lbs and it would be nice....

 

couldn't I go with the type-s and just use a thicker head gasket?

Of course, you are spending more money on something you don't need. You don't need the higher compression pistons or the better cams. Save your money, get a USDM H22 and spend it towards your turbo parts.

 

a turbocharged h22 in an eg is more trouble than I would go through. but if u are gonna boost, go with lower compression like everyone else said

 

I'm with everyone else, an H22 isn't usually the first choice if your going to boost. Personally, if it were me, I'd pick up a newer, clean, B18B. I'd then build-up the internals for boost.

Your choice though...

eveyone does this....build the single slam and then boost!

 

have fun wiring that bitch up and spendin money sleevin that ho b4 boostin it.(shitty cylinder walls)(well atleast all my friends had shitty cylinder walls)

 

Personally i would go with the h22 because of the lower compression than the type s motor. The cylinder walls are really not the problem if you want to run around 5-7 psi. The ringlands ussually go bad on the h series motors. My friends has been running his h22 and 8 psi for 7months now and has had no problems. But then again it was very well tuned. If I were to boost any more than that on my motor i would go all out on the motor first. I would have the block blueprinted and sleeved go forged pistons and rods and all new valve train. But thats just me i like to know my setup is going to be reliable1

 

Yeah, I think I will just get a USDM H22 unless I find a JDM H22 for a good price, I found all the info I need, type-s's are good for all motor but I'm not interested in doing something like that, thanks for the help though.
