WTB : 4-6 STD EM Forged Pistons
Posted by: jazzworkerbee ()

I know, I know, they’re as rare as hen’s teeth but after finding two stock forged TRW 145 pistons, I’d be a fool not to check the forum to see if I could find four more. Well, does anyone have any that they are willing to part with?

Thank you,

You might have checked the earlier threads on this topic before buying those. The seller advised me that he could not locate others. Those are correct 61-63 forged pistons made by TRW. Since you have a sample for scanning, you probably can have more made pretty readily. I decided to go with stock pistons when I could not find any 2156 pistons anywhere.

Thanks. I spoke to that fellow and those are cast pistons. I’ll just have to wait.

yes, you might have to wait a long time to find some other pistons to make a set.

I'm wondering if it might be cheaper to find some longer rods that might work with some LM 164 cubic inch forged pistons? Or just get a long stroke crank and make it work?

I went through this same conundrum a few years ago... I tried to find a pair of either early forged pistons or a pair of early "Hitech" pistons which are supposed to be as strong as forged. After a long search, I gave up and bought a pair of Clarks "Premium Grade" cast pistons. I would have much preferred to not do that, but I have had those pistons up to 22 psi, numerous times now and have approximately 12000 miles on this goofy set of 4 "Hitech" pistons and a pair of "Premium Grade" pistons with zero problems. Moly rings with a good ring gap, good safe timing and fuel air ratio for the load with the idea of staying well away from detonation and not going much past 20psi is probably more important than the piston construction.

Right... I don’t expect to ever find all six, but I figured I should try as I continue to solve other problems here and there. Who knows, I might get lucky or someone on this forum may find some in a box that they’ve had in their garage for 20+ years.
