Pistons

Since I like running higher CR's for my street-ish stuff for a wider torque band, I like these. And I've run hyper's with a turbo rally engine at 14-15 psi boost with no issues before. They are lighter so you should count on a bottom end re-balance.

BTW, my son and I put KB hypers in his 340... so far so good. With SCAT rods, this combo shed considerable weight off of the crank.

But, important question: What is your planned engine usage?
