Im attempting to replace my blown 3.8 on my 03 Monte carlo with a Supercharged 3.8 out of an 04 Grand Prix. Please...someone say they done this successfully. Im having a heck of a time.

 

Series 2 supercharged 3800?

 

Its been done before, at least on the 98-03 GP side.

The two big things to fix will be the TB and fuel rail.

The L32 rail is returnless, but you should be able to use L67 rail and injectors.

The TB, most do a N* adapter and swap to a cable N* TB.

Also I want to say MAP and EVAP are different too. MAP you should just be able to use the L67 MAP and EVAP is generally blocked off and run off the TB adapter using the L67 stuff.

Yep, 04 GP would be a S3 / L32.
