i'm gonna start my single turbo manifold and i would like to know whats the smallest turbo that i could use on my na motor and also if i get it used ,from what car? thanx guys!

 

Why are you looking for the smallest turbo? If you are going to be buying a used factory turbocharger, why not get once suitable in size for your application, since there isn't a big price difference?

Off the top of my head, maybe a CT26 found in a MKII MR2 or MKIII Supra, or even a Powerstroke unit from a Ford 7.3L Deisel truck.

If you plan on upgrading to a good performance turbocharger in the future after your setup is working, make sure you choose a turbo to start with that has a comman flange size, such as T4.

 

just use the stock 13B turbo its fine..

 

well i'm gonna start looking for a nice used one! hey what about a turbo from a saab? , i know it sounds a lil' crazy but i'm just having fun w this project and i will not spend a lot of money! thanx guys!!!!!!!!!

 

The turbo Saab's used very small T3's, mostly with 40trim Exhaust wheels, and .48 a/r Exhaust housings, which are WAY too small for pretty much any rotary application. I'd pretty much stay away from any straight T3's, unless you're going for near-instantanious spool and a very compromised top end

 

thanx!!!!!! i' still working on my project!
