Burnz

K, I have a 1988 RX-7 GX, it's a canadian model. Nobody seems to know hardly anything about them, and I can't find anything on them. someone on here thought it is the same as the American SE. All I know about it, is it has 4 lug wheels, was 5 speed transmission, and naturally aspirated.

So, it would seem that it does NOT have a limited slip differential. I've got a 400 Horsepower engine going in this car, so that's an extremely large letdown. I can't be doing peg-leg burnout's in this thing, and it's not going to hook up.

So, what I need to know is, are the dimensions of say a Turbo II or GXL rear end the same as the ghetto open diff. in my car? I'm getting a driveshaft made right now, so it does matter. And how big of a swap is it to change differentials?

Any info. is appreciated... THANKS.
