I have my 1994 GA16DE turbocharged at 9psi with stock pistons, I'm looking for pistons to at least make 15psi, here in Puerto Rico some guys use vitara pistons on Hondas, Do anyone knows what piston can I put on my car?

 

knowing the ga very well i regret to inform you that there are no pistons that will drop the compression ratio sorry.. (i have one myself so i feel your pain)
