Ok, i have done something that i never thought i would ever do...Im cheating of ford with a chevy. Well, i have decided to sell all my 302 stuff and go with the LS1 swap just because it is so light, and has so much more power than the 302. Now, i have some questions. 1)Is there a bolt up rearend that will hold 350-400hp? 2)How hard would it be to bolt up a corvette diff? 3)I want wider wheel wells, so i was thinking of maybe a minitub. Im guessing it would be easier to mount up that corvette rearend right? thanks. Sorry if this question has been posted to death, i just didnt find any useful info when i searched.

VQ30DET -> 260Z Has it been done? 1 2

I've been considering a few different engines for a swap into my zed, and one interesting option is the VQ30DET. And yes....that's VQ, not VG. It's from the Nissan Cedric's and Cima's AFAIK. Being and all alloy V6 I'd imagine it would have the weight advantage over the RB's and VG's, and would give a better weight distribution than a straight 6. So has anyone heard of this swap being done into an early zed, or any other comments on the idea? Edit: They are quite well priced too..... AUS$2700 for a front cut.

differences between L28 and L28et 1 2

hey guys, i was wondering if someone could explain the differences between these two motors. as i understand, the L28 comes in 75-78ish 280zs, and the L28et comes in the 79-83ish 280zx turbos? they are both straight 6's, but what is different between them other than the turbo (or lack of)? i understand that the L28et has about 31 more HP than the L28? is this correct? My application is im trying to figure out what i want to do with the engine in my 280z. ive been told by people on here that putting a turbo on a L28 is a little more than worthless, and that i should just swap in a L28et...if i swapped in a L28et, i would rebuild it first...and if im going to rebuild the L2…
