ok, I've searched almost every site known to man that has anything to do with boosting H22s...I have never found a definitive answer to this question, some people say yes and some say no on every thread and it'll probably happen here...
Will the 1g DSM mani's ports match the h22's? If not what other cars have the same ports???

 

well here is you definitive answer.. NO the h22 port nore the bolt holes on the dsm mani line up

the h23 ports line up to the dsm mani and some exhaust stud holes need to be redrilled ie moved over alittle.

so it doesn't fit the h22 but will fit the h23 with some modification.

take this as set in stone, and stop searching i have personally tried this and it will only work for a h23.

 

ok, thats all I needed, someone who has actually tried it...theres too many "my friend" or "this guy I know" info...thanks!
