OneHotLexus Posted December 19, 2003 Share Posted December 19, 2003 I have heard that the SC300/400 comes stock with forged pistons. Now I can't remember where I heard this or I'm thinkin I might could have dreamed it, I dont know. So that's why I decided to ask ya'll. Any replies are appreciated. Thanks!

UCF3 Posted December 19, 2003 Share Posted December 19, 2003 I haven't heard that before. Since the SCs are using one of the Toyota Supra engines, it's possible that you can get forged pistons. Quote Link to comment Share on other sites More sharing options...
Sadistic Posted December 19, 2003 Share Posted December 19, 2003 From what I deal with, they all list the Pistons for the GTE, which since the block is the same from what I undersand, they SHOULD still work.. someone correct me if I'm wrong on that.. Not sure about head clerances though.. Weisco 8.25:1 Compressin CP Forged 8.5:1 Compression JE/SRP 8.5:1 Compression That's what I have listed without digging too deep.

AWJ Posted December 19, 2003 Share Posted December 19, 2003 The factory OEM pistons are indeed forged and resin coated. I know this as fact in the 2jz-ge inline six from 1992 to 1997. Anything above and beyond that, I'm not sure on. But think they are forged pistons into the the last model year. There is a performance specs. thread pinned up there that has all the details of the 1993 SC300 that basically holds true across all model years with the exception of a few body style que changes, creature comfort option addtions, and the introduction of vvt-i in 1998. Here is an excerpt: 225 hp forged steel crank - held by seven main bearings a two piece oil sump that actually adds rigidity Acoustic control induction system (ACIS) varies the length of intake runners - long at low revs and short at high 5 speed manual or 4 speed auto with ECT 10.0:1 compression ratio High strength hot forged connecting rods with oil jets Resin coated pistions - large valve diameter 1.23 hp per cubic inch Quote Link to comment Share on other sites More sharing options...
Lextreme Posted December 20, 2003 Share Posted December 20, 2003 Sorry to inform you. I have opened up few 1UZFE (SC400). The pistons are NOT Forged. They are casted with special coating. I am not sure about SC300 and 2JZGTE motor. Quote Link to comment Share on other sites More sharing options...
