now some guy told me i could put an eaton m90 supercharger off a grand prix or t-bird with a 3800 V6 engine in it on my 3.1l V6 firebird.......can anyone please tell me if this is true or not

 

You could, but it would be difficult and require a lot of custom parts.

 

well now i heard that even if i somehow bolted it on that it would "blow" my engine...does anyone know if its been done before.

 

u should look in the v6 section, chances are u will find the info u want in there

 

The 3.1 and 3.8 are totally different engine families.

 

the t-bird m90 is a yes...

There is a coupld people that have installed a t-bird m90 in a fiero so obviously it will have room in a f-body. The M90 is a awsome supercharger and has the Potential to blow your engine being that a M90 can produce 20psi with out damage to the supercharger but the 60v6 may not take it. I have a M90 from a t-bird and I have played with the placement in a v6 firebird and there are tons of options and keeping the AC as long as you have a welder and can get your measurements right. Though I gave up on a boosted 60v6 because it is more cost efficient to go hybrid 3.4/w 3500 top end and stock 3.4 pistons for 11-11.5 cr and about 300-340hp. I will be using the supercharger on a 3.8 for my monza and adding another m90 for a drag beast.

 

i have a couple questions....would u recommend i use an m90?i also heard that in 91' grand prix's came with 3.1l w/turbo(i no it's fwd)or how about the cobalt ss supercharger do u no if those r any good....and if not those do u know of any supercharger i could use for it?

 

the cobalt supercharger is an m62 and is to small.

the tgp's had a t25 turbo and made 205 hp with a turbo that was way to small

the m90 is the easiest option for mounting and installing over a turbo.
and yes the motor can take it
