GN 3.8 swap - Third Generation F-Body Message Boards

Hi All,

I am new to this forum but not to the car world. I was heavily involved in the import scene with my eclipse but have now acquired a 1992 camaro RS with a 3.1L in it (5s manual).

I would like to swap a 1987 GN T engine into it. Should I start with a long block and build from there or try and find a used engine? Or try and build up my current motor and put a turbo in it? I must have a turbo V6, the V8's are nice but I like the gas mileage of a 6

. I have read on the GN forum that the GN motor doesnt accept manual tranny's, is this true? If not what tranny can I use for this engine? What am I looking at price wise for doing this build? (I can put the engine in myself) Any info would be great or just point me in the right direction......

TTAs started with the GN V6, but had different heads & (i think) different turbo.

So you'd probably be better off starting with a short block & going from there, so your not having to tear down (like the heads) & buy new/different ones.

Welcome aboard thirdgen.org.

There is a tech article on this topic linked from the thirdgen.org homepage.

The GN's & TTA's had TH200-4R's behind them.
