Guest Ejk240 Posted September 17, 2006 Share Posted September 17, 2006 Hello everyone, I am new here to hybridz but i think i can get more information here than i can on z31.com. Anyway, i just bought a 1993 Thunderbird and it has a 5.0 HO motor/AOD transmission in it because for about 6 months now, eversince a guy next door put a 350 in his 300zx, i have wanted to beat him in a drag race with a ford powered Zcar.(my stock turbo 300zx wont cut it). since i took the turbo motor out of my 1984 turbo and put it in my NA 300zx, i now have a car to put a ford small block in. So i was just wondering if anyone has done a EFI swap(I've seen a carb'd one), this is my first question. Now my second question is if anyone here has ever put the 8.8 rear end out of a thunderbird up under there Zcar. This would really help because i know that my rear end is open differential and the thunderbird on is trac-lock. FYI: I also have experience in fabricating because me and my dad race a 1972 pinto with a 351W with a 9 inch rear to back it up, so i might not have alot of troble with the motor mounts. And i am also planning on, after i get the v8 set up right, driving it back and forth to NC State University next year. I am also trying to join Wolfpack Motorsports(http://clubs.ncsu.edu/motorsports/) I will apperciate all information greatly. Quote Link to comment Share on other sites More sharing options...
b__sosick Posted September 17, 2006 Share Posted September 17, 2006 DYNO TUNE YOUR z31 it has timing problems i PROMISE. upgrade the intercooler, turbo, injectors, exhaust, throttle body, intake mani, and i promise you'll get your boy with the 302 z31. :] you'd be surprised how far dyno tuning can get your car. it might be expensive but once you see the power increases you'll forget about it.

rudypoochris Posted September 18, 2006 Share Posted September 18, 2006 Not sure about Z31's but I believe there are both s30's with the EFI swap as well as s30's with Ford 8.8" around. I personally think your idea is good one compared to upgrading the stock motor. It would take a considerable amount more boost and modifications to the stock unit to make it beat even a stock Chevy 350 (depending on year I guess).

Guest Ejk240 Posted September 19, 2006 Share Posted September 19, 2006 Hey, Thanks for the comments. But i have ran the question of the 8.8 rear by some of the people in Wolfpack Motorsports here at NCSU and they said that it shouldn't be a really big problem adapting the 8.8 rear end to my 300zx, except for making the mount for the differential and the half-shafts. Another thing i found out about the efi 5.0 swap is that, when i get the 5.0 in the car and get everything running properly, I could easyly put a 351W in its place, roller perferably, with little modification.(Just slightly bigger injectors, a new MAF, and a efi lower intake) This is just information for anyone who wants to know. I apperciate the comments. Quote Link to comment Share on other sites More sharing options...

Not sure if a 5.0L HO intake will bolt up though.... might just get a bronco EFI intake. Quote Link to comment Share on other sites More sharing options...
LMoore56 Posted September 19, 2006 Share Posted September 19, 2006 The 351W has a 1 inch taller deck, which in turn makes the intake, right around 2 inches wider than the 302. The main journals are also larger on the 351W, than the 302 also. So the 351W oil pan will not fit a 302 either. Quote Link to comment Share on other sites More sharing options...
