thanks for the comments, my concern is that it's a unibody with a frame bolted on the front for the motor (i haven't actually looked yet though but this is what my research says, i'll look before i make any decisions), i'm afarid the first time it gets traction with 300 lbs of torque the back half of the car is going to pretzel on me. Looking at it last night though, i might be able to weld in some frame on the inside and have it pass through the interior, there is quite a bit of room for this i think. Then i can hang whatever rear end i want from that frame as it comes to the back of the car. will this work? can i build a frame like that and have it support all the power to the ground or am i asking for more trouble? I don't want to stick a big motor in but never be able to floor it, that would be lame.....
