i was wondering if it was possible to turbo a h22 with type s pistons that is bumped up to 11:1 compression. if not what would i have to do without sacrifceing the type s pistons.

 

you can use the type s pistons, but it isn't recommended, unless you tune everything very precisely...11:1 is a very high compression ratio to use in any turbo application, and i don't know of too many cars (other than indy cars and turbo diesels) that use such high compression when turbocharged...

 

thanks, thats what i thought but i just wanted to make sure

 

You could try to use a thick headgasket to help lower compression but it wouldn't drop it to 9:1 or anYthing

 

Proper tuning is key for reliability and efficiency.

 

It is possible but with high compression, you will have little room for tuning error. However, you would make some good power if you boost type-S pistons.

 

so pretty much i would have to have someone that really knew what they were doing to tune the car, to make sure i dont blow it.

 

I would suggest that you do a different motor for turbo because 11:1 compression with turbo isn't reliable for daily use. You have a very slim chance of getting it tuned right (not saying it can't be tuned for it) before it blows up. If you had it tuned just right and a spark plug went bad it could mess up everything.

 

so you suggest to just go with the h22 without type s for everyday use. but what do you suggest for daily/drag strip driving. not street racing but like the 1/8 mile tracks and 1/4 mile tracks.

 

For drag get a crx or civic hatch and drop a h22 into with boost.

 

If you are going all motor the type S is good. If you want to turbo go with another H22 and lower the compression to around 9:1. 9:1 is ideal for turbo. You can run more boost with it which compensates for the lower compression and there are no risks of high boost if it is a built 9:1 with boost.

 

thats what i want is high boost. thats why hopefully when i get money the motor is getting sleeved. so i guess im going to shoot for 9:1 compression.
