Re: B18A1 compression

sure why not but it shuold handle boost pretty well also. the b20 head is also very similar to the b18 head if not the same...the b16 trans will be great with it as well.

Re: B18A1 compression

it will run fine, it's just not ideal if you are trying to make any power naturally aspirated. basically it would be slower than a stock ls. with a c/r that low you should definately be boosting it.
