Not sure how much power you will gain. I put a 0.5mm 10.25:1 Wiseco in mine a couple months ago. I didn't notice a big difference but it seems to have a lot more torque than before, but then again it was smoking like a stack to start with. After searching the net for a few hours, I found the best deal on Amazon.com actually.

My brother in law has an '85 350x that is all stock and runs great, no smoke at all.

My brother has an '86 with the 10.25:1 piston, K&N and DG exhaust.

I have ridden both machines enough to really know how they run. I can't say how much or how little the K&N filter and DG exhaust help my brother's '86. But I can say the difference in snappyness and torque is very noticeable over the bone stock '85.

I believe the 10.25:1 piston is a good upgrade for the 350x.
