someone had this done just makin sure its possible ? is it ? with out problems

 

??????

 

i've never heard of it but i know someone had put a k20a tranny on a h22 w/ some bracket.

 

Why not just get Prelude Type S pistons (11:1) and put them in there?

 

Exactly which RSX pistons are you talkiing about? Base RSX compression is somewhere in the 10.x:1. RSX Type S are 11.0:1, and Type R are 11.5:1. I guess as long as your H22 has an 86mm bore then it wouldn't be a problem.
