single turbo
 

Do you know where i can find a Install diagram, so i can install one of theses things in my supra? I'm buying one from ebay, and i'm sure that it doesn't some with one. And ideas?:sadwavey:

Hmmm...honestly never worked with an ebay turbo kit. I'd recommend you don't get your expectations too high - it may not fit right. Hopefully you know folks that can weld/machine/port/etc it to work & fit correctly before you do your final install.

Alternatively, consider not buying the one from ebay, and getting a higher quality kit like HKS or Sound Performance...

Here's a write-up that you may be able to use...

I have an non turbo supra. i noticed the port for the oil return but it is not open. What do i have to do to access it, is it just a punch out like a freeze plug or do u know. Also what fuel delivery mods do i need to do? All your info is much appreciated.

The n/a isn't really suited for turbocharging, and requires a lot of mods in conjunction with the turbo addition. About the best advice I can give you is to save up for something like this:
Boost Logic Stage 1 NA-Turbo Kit :: Turbo Kits :: 93-97 MKIV Supra NA :: Toyota :: Boost Logic
