Part #: SC7452 (5SFE Crank with 3SGTE Block)
those wont work, they are for a 3S-GTE block. stock pistons will be fine at low boost < 250HP -------------------- 2001 Celica GT-S Turbo

QUOTE (Smaay @ Apr 28, 2009 - 6:23 PM)  stock pistons will be fine at low boost < 250HP  I suppose the stock pistons are fine at those power levels. Supershannon77 has been running 285whp and 300ftlbs (thats 320+hp and 345+tq) for about a year now and still no issues. The stock 5s has been proven time and time again to accept 15+psi without ANY issues.....It really should be just about written in stone that the 5s pistons are safe at 15psi and sub 300whp (remember thats about 350hp at the crank.) --------------------
