CP Pistons

[pepsi21463]

Has anyone used these in their DSM? I've searched around here and dsmtuners and can't find anything. I'm not trying to decided if I want them since I already have them in my car, just curious if anyone else has them and what they think. I'm doing a CP Piston and Manley Rod combo, just wanted to see how rare that actually was, if it's even been done yet

Moved to Parts Talk.

It's been done. Gas ports on a forced induction engine isn't necessary, though, and could even be detrimental. I think you can get them without the gas ports.

You can do gas ports but it has to be done a certain way. If you don't know what your doing then ask for the pistons not to have them
