type r pistons

Ok so I got factory ITR pistons going into a b18b1 ls motor with only an intake and a header full exhaust system. What kind of gains am I looking at as far as horsepower torque top end and bottom end speed if any noticable gains at all. New to the engine building so...

CTR pistons would probably give you the bump that you are looking for if you plan to stay N/A.
