I thought I was the first to do this swap, but now I see I'm not. So, are either of you planning to sell swap kits?
The stock 300ZX differential assembly and axle shafts are strong enough until your 60-foot times get to the 1.6 second range. I'm also going 4L60E. Which oil pan did you use? And which exhaust manifolds?

Damn I was hoping to at least get my 5.3L in my Z before anyone came along and stole all my glory lol. Well looks like a great build man. I currently own 2 86 300zx!
Oh and to let you know Im doing the same exact swap into an 86 300zx, but I'm going with a t56 and the turbo Im going with is the Borg Warner s475 83mm turbo.
If anyone needs any help also I can help also! and just to let everyone know now there are about a total of 6-7 z31 owners doing this swap now!
Another thing the best oil pan to use for this swap is the Auto Kraft oil pan as it does not sit lower than the stock crossmember and allows you to sit the engine as low as possible and as far back as possible without oil pan modificaion!
One last thing also if you guys are looking to swap rear ends go with the s13, q45 and z32TT hybrid rear end, thats what I have and it's strong, it consists of s13 subframe, q45 diff, one q45 axle and one z32TT axle

Still no good gearing that way. And the diffs are still way overpriced, with too few choices. I'm going with the Ford 8.8" from a '90 Thunderbird. Gearing choices range from 2.73:1 up past 5.38:1, and there's a dozen different styles of differentials, all under $600 each. The T-bird was 28-spline stubs, but with a 31-spline diff, the later Mustang Cobra stubs are a direct fit. There are also billet inspection covers and billet mounting brackets available for the Cobra, and these directly bolt to the T-bird version also.
Also, that AK pan is $400! I was thinking more like $50 for a used production pan. I have much better uses for $350.

as for my rear end I want to see how it all holds up to the power and if it goes quickly then I was thinking of doing the same sort of swap from the TBird!

you should be able to register no problem now, I think it was because the forums were going through re-development!

I'm doing a similar swap right now. I'm putting a LQ9 iron block LS3 single turbo(custom 78mm billet impeller Precision) in a 1990 300 zx. If you're looking for some suggestions on the turbo piping - shoot me your number and I'll give you a call to discuss. I did a ton of research on mine and I've pretty much got it sorted out.
