Just wondering what I should set my PTW clearances at when running a JRSC with RS machine ITR replica pistons.

Ive searched and came up with .0015"-.0018" but those seem alil tight for an FI application.

I tried to contact RS but the phone # has been disconnected, I emailed too but dont have much time to hear back. Any help is greatly appreciated



Just for the record this was much easier with my JE pistons on my old turbo GSR

 

RS pistons are cast aluminum not forged like JE, CP etc. Cast pistons expand very little that is why you do not need such a large PTW clearance. .0015" will be fine.
