I have a 98 type R and I was wondering your feedback regarding getting oversized pistons with higher compression. I also want to install a jackson racing supercharger. I want to make sure I don't ruin the motor. I don't have alot of experince with cars so any feedback will help. [/b]

 

I hope you are not joking, but don't increase the compression, you will never be able to run pump gas without detonation. 10.6 to 1 is high enough. If anything, keep it the same, or lower the compression.
