I run a torsen LSD for many years on my SC400...It drives just like the stock open end differntial....Mine came out of the 1995 Supra tt (auto)... I don't know which ones are compatible with the SC300's....
dcoydad - I am running the stock 1uz-fe V8 motor on the nitrous... I've pushed 350whp and close to 500 torque...Probably run in the high 12's would be my best guess, although i've never timed it... I've modified everything on this SC400 mine...LSD, exhaust, headers, intake, ECU piggy, electrical, lowered, etc... It's good to go and has good off the line traction for an SC4.....
I don't lose too many races just put it that way....
How's your lowend power the 2jz? The knock on the 2JZ's is they are a bit gutless out of the blocks with turbo boost.. I've got a friend laying down 1200hp on a 2jz powered Supra with a huge single turbo setup...He had to run a nitrous shot just to get the turbo to spool and get the car moving from a dead start....It's a track run monster that fly's in the low 9's.......
