Pistons

[StevenCJR31]

Hi, can anyone here tell me if rb20det and rb20de pistons are the same or are the na pistons higher CR ?

I think they are different, according to this post by simon they are anyway.

EDIT: just checked and RB20DE/DET bore and stroke are the same, and i believe all RB headgaskets are 1.3mm, so that really only leaves the pistons to be different. Check on JE/CP etc website and have a look. I CBF doing that for you

Head can be different as well.

I'm of the opinion that the NA pistons are in fact different to the turbo ones.

Im of the same opinion as GTSBOY that the na and turbo pistons are different. Na pistons different to gain a higher compression ratio. What do you plan on doing? Can always run a thicker head gasket to get the same compression. Although not ideal.
