9:1 mostly stock sr question

[626ls1240sx]

I'm currently rebuilding my engine and I havent found an answer in regards to what I need to do to run 9:1 on my motor.

Mods are just 87mm 9:1 supertech pistons and a 1.1mm head gasket. Stock turbo and everything else. Do I need to change anything since I'm going to run 9:1 pistons?

Not technically, just make sure you have a way to tune the motor for the higher compression.

^^ +1. IIRC, there will be more potential for detonation with the higher compression; so like he said above, you will need a tune.

+3...engine management and tune will be key!
