Out of a 22R. Anyone know what piston this is, stock or higher compression? I was told they were TRD racing pistons from the guy I bought the truck from. But have found that he didn't know what was in it. Isn't there normaly a stamp somewhere if they are + .020 .030 or shuch? these don't have any.



Check out the timing cover.

Thats what my stock pop ups looked like. Seems if they arent marked as biggier then just measure and look at factory specs. But my hunch if the guy is shady then they are just stockers.

Are there any good deals on high compression pistons. Only found some LCE ones for $588 a set with rings. I plan on running propane and want to be at about 11.0 - 12.0. sugestions

Those look like cast stockers to me.. They're cast for sure!
What happened to that motor?

It depends on which block you have (early or late) - but I've found some KB pistons for about $275 in various compressions:

I believe they are the hyper-whats-it pistons, better than cast, but not as good as forged. They may have different clearance requirements over the stockers.

What are you doing with your motor? Why not use the stockers ($<100) and cut down your head for compression?
Custom pistons are $500-$600.
