Hello,
I am playing around with the Idea of installing lower comp pistons. My question is, if I dont plan to run more than 10 PSI of boost, would I be required to resleeve the Cylinders and upgrade the rods... or can I jsut install the LCP......

Thanks
Beroz

 

mods could u please change the title to - Is resleeving a must?

 

I don't like the idea of putting aftermarket pistons in to a motor with aluminium walls. With that being said, it's possible, but there is a special coating which is required to get it to run correctly. JE is capable of doing this, but they won't unless you talk to them about it.

It's actually possible to run 11 psi with stock internals, with engine managment and good tuning. I don't trust this setup at all, but it's been done before.

Lastly, Mike Simon and have been doing some research on what you can and can't get away with replacing in an S2000 motor. We are both convinced that sleeving it is a must, as well as aftermarket pistons. I think that if you're going to spend the time to get your motor rebuilt, you should do it right the first time.

When you rub aluminium with aluminium it attempts to bind together.

It causes this to happen:
