And I saw some rebuild kits on ebay like THIS, are these good ? Because if it can hold this amount of power I don't mind paying for rebuild once every ~15k because I won't be driving too often.
I know the brakes are better on the twinturbo, but are these necessary or just recommended ? What about the diff and ignition system ?
Thank you again for taking your time !!!!!!! 
L.E: What are the exact differences between a TT and a NA beside : brakes, turbo, tranny...do na's have ABS or Airbags ? |
What's up man? Welcome
Glad to see you're so passionate about the best car in the world -SUPRA
Take a look at this technical article:
www.mkiv.co.nz (check under technical section. A wealth of information on the Supra helped me a great deal. I'm also in the market for one - I desperately want/need it
I found great deals in it's homeland of Japan so, I'll be getting a JDM spec - oh yeah!
The w58 N/A tranny is capable of 260rwkw (I think that's 360HP) whilst the TT's auto A340E is capable of more at 350rwkw (+-470HP) and the king V160 6 speed TT tranny is capable of a whopping 500rwkw + (750HP)!!!
Definitely the one to go for if you're running that power. N/A is great and very affordable. However, the Twin Turbo is the undisputed king and ultimate Supra MKIV - if you could possibly afford one, please buy it. If you really cannot, set up a careful budget for your N/A Turbo conversion - if done well, the 2JZ-GE can produce massive power as well. It's just much more costly of course.
As for differences between the two, the article will have you covered there. Suspension wise, the TT came with Bilstein shocks, better ABS system, traction control as standard, spoiler control. Since you will be buying an export spec in the UK, the brakes are bigger than the N/A's. If you're buying from Japan, 93 - 95 Supras had the same size brakes for both TT and N/A. If you're pushing much more power than standard, upgrading them is a good idea with bigger rotors or at least slotted ones with better pads to match. If not, the Supra's original brakes (TT, especially) are very, very good in road or track scenarios.
Best of luck bro! Keep us posted...
