Gt 28/76r On Rb25det?

[Jamie88]

Hey guys got a good opportunity to swap my highflow 25 turbo for a garrett gt 28/76r as my mate wants a smaller turbo for his 4cyl. Now this poses the question on how to go about mounting it on my rb25. This turbo has an sr20 flange on it (T2??) so its gonna have to have the flange on the manifold changed. Im guessing its gonna have to go highmount and just get the exhaust shop to change the flange for me? Any ideas guys?? Let me know. Also cant remember if the turbo is oil and water cooled, so how would I go about the different lines? Braided is obviously the right way to go.

Any help would be great

Your hi-flow would/should be a better setup than a GT28

IMO its a waste of time

I think you can get/make up an adapter flange but its alot of mucking around

Haha that would look funny high mounting that pissy little turbo!

Waste of time.

Visually a GT2876R is not a small turbo, look pretty much like a GT3582R or a T04Z with a little turbine housing - but they are a piece of crap. Stick with the high flow.

I agree with Lithium....the 2876 has a big ass comp wheel being spun by a relatively pissy exhaust wheel.....its a mismatch of a turbo IMHO.

As above the GT2876R is a bit of a missmatch turbo. the compressor wheel is too big for the small turbine side. Garret even give clues to this on their web page for this turbo where they say;

* Best suited for unique applications such as asymmetric turbo installations

* Not recommended for general performance applications

IMO your better of going a GT3071R where the turbine and compressor sides of the turbo are better matched.

Ok thanks for your help guys Il tell him not to worry.... Appreciate it. And visually the 2876r is not small
