Piston oil squirters

[B0oStEr]

I've been told the r32 rb25de doesn't have piston oil squirters nor do the rb30 motors.

I was only aware that they are used in the rb26.

What about the r33 rb25de/det or my rb20det for that matter?

How important are they if you use forged pistons?

All of the DET's have block mounted piston oil squirters, other RB's have conrod oil squirters. The extra oil cools the under side of the piston, if you ceramic coat the piston crowns the conrod oil squirters do a totally satisfactory job:cheers:

PS; you can fit oil squirters to SOME other RB blocks but it is hit and miss (depends on casting thickness) and is a pain in the ass job that needs special tools.
