I would want to use an NA Series 2 3800, not a supercharged one.
The Isuzu 3.2 V6 in there now makes 180 hp and 180 lbs of torque. It would be nice to bump that up to 205 and 240...

3800 would most definitely get better mileage

You can but you will only be able to mount the rail down with 3 studs. The F-Body rail as 1 stud in a different location. Plenty of people do this without issue though.

205/230 is the power of a stock FWD L36, 200/230 is the power of a RWD L36 from an f body

Thanks for all the input on this. I'm going to do some more research and see how feasible it really is.

The F-body has a metal Upper, which is supposedly not quite as good at producing power as the composite upper of the FWD versions, there might also be some exhaust differences.

Look at all the variations for the 3800 even with the FWD sector, 205 for H-bodies, 200 for all W-bodies with the exception of the Intrigue which only got 195....how? Who knows.

didn't know that

a bit off topic but was the non-composite also prone to failure too :?:

The f-body intake can flow better, supposedly. That is my understanding. I think you probably lose the 5 hp due to the smaller plenum size. Nothing that can't be fixed with a little cut and weld action

The plenum size probably isn't that much smaller since a large portion of the FWD L36'* plenum is filled with the intake runners themselves.
The RWD TB is significatly smaller than the FWD though.

I have both the RWD and FWD UIM/LIM in my garage. If anyone has any measurement questions just let me know. (except for volume stuff, that takes a while)
