will a L32 Eaton supercharger v6 3.8 from a Grand Prix 2004 bolt up to a 2004 ss Monte Carlo v6 3.8 series 3? Thank you for your time

 

You will need more than just the supercharger if your car doesn't have a supercharger already. And fyi the 2004 Monte Carlo is a series 2 not series 3.

Google search "3800 top swap" or "3800 gen v swap" for more info

 

Thank you very much , my 2004 ss Monte Carlo is supercharged I took the nose cone to a high performance shop and was told it was a series 3 m90 Eaton v6 I bought this m90 used Eaton supercharger in excellent shape so I could get it on the road b4 I can afford a new one. Will the Grand Prix supercharger still compatible looks identicle to mine! Thanks again

 

On your 2004 Monte Carlo SS — The m90 is a GEN 3, but the engine itself is a SERIES 2, 3800.
On a 2004 Grand Prix — The m90 is a GEN 5, and the engine is a SERIES 3, 3800

You can upgrade your L67 to the GEN 5 blower, but it's not a direct swap. Here is a link that outlines it pretty well: The Eaton Gen V supercharger faq / swap thread!! (genv, gen five, gen 5))

Conversely, you can just get your GEN 3 blower ported and see similar gains.

 

throttle body is different on gen 5 eaton m90 how can I make this work you were right thank you am desperate any suggestions
