Yeah, sorry about that I usually mention replica. The LS7 doesn't put out the power that Kevins turbo ls4 does and although the LS9 does, it costs about $25,000 the last time I looked, plus they are a lot harder to fit transverse in a fiero. Anyway I would still have the input shaft problem. When you say just a lambo replica you should understand that it has custom wide suspension,13" brakes and the turbo ls4 which should have the same hp as the lp640 with a few hundred less lbs and no power loss through the front differential, so it should be able to perform as well as a real lambo without all the maintenance outlay. Even though I'm having problems with the 4t65e hd, I'm pretty sure it's going to be cheaper to solve than a broken lambo tranny.
