Now if your building a engine with cast pistons or 4032 forged pistons I believe they are still needed. Ive seen the power differences of SR20DET and 4g63 running cast pistons with and without oil squirters. Theres an obvious difference in durability where the oil squirters show better results. A 2618 forged engine however won't care either way regardless of rpm and hp simply put.

It's certainly possible to make power without them, but I would rather have tighter tolerances, extra piston cooling, and extra lubrication.
