Ive searched google and google images a bit with no good info yet so ill ask the only non musclecar forum im proud to be part of...

The GM 2.9, 3.7, and 4.2 are similar and im thinking about working with all 3 of them in my garage. I am putting a turbo 4.2 in my IROC-Z , the Hummer's 3.7 is having a supercharger made for it right now and I want to put a 2.9 in a sandrail.. Id like to know if the supercharger can be taken from my 3.7 engine and swapped to the 2.9 or even the 4.2.

Pics of the blower will be posted when available.. Im the guinea pig for the kit. Details include a billet scroll, billet compressor wheel, self contained oil and ball bearing operation.

Any info or links are appreciated, thanks!!
