So right now i have a turbonetics t3 turbo that is oil cooled and not ball bearing vs a t-25 turbo that i have as well that is water and oil cooled and ball bearing. both brand new and im building a ls to boost and only shootin on 200-250 whp range and not really lookin for high rpm range. what turbo should i run ?

thanks,
shaun!

 

The t3 is considered small for a d16, so a b18 would really suck with a t25. Chances are its a super60 T3, so you'd probably get 250whp with 7-8psi with a decent exhaust. The a straight t25 is about 200max (safe for the shaft), and a t28 will be like a fast spooling, high-rpm-sucking t3.

Cliffs: T3 or bigger.

 

T3/T4 done.

 

Telling him to get a T3/T4 does not really help when he has already narrowed his selection down to the two turboes that he already has.

To the original poster: Which GT25R do you have, Garrett makes atleast four different versions of it. The same thing goes the T3, which T3 are we talking about?

It is hard to help out without more information. . .

 

thanks guys
MrMoe:
The t25 is from a turbo specialties kit.
