[Supras] JE Pistons

[Fred]

Either way I have to buy pistons, stockers w/ rings  will cost about $570, 
forged JE w/ rings about 170 more. Do you think forged are a worthy 
investment? My machine shop is urging me to go forged. I have a  similar set 
up to Bernies and probably many others,  including the HKS filter that is 
going in the round file. I think the forged are lighter, 296g not sure on 
the stock piston weight, can't find the spec.

57 trim performance techniques, cooleeze pipes, stock IC for now,  550 lex 
w/reg bolt, greddy boost controller, 3" elbowless defcon dp, 3" hks exhaust, 
no cat needed here in WA.
