Supercharger for a 2007 Pontiac Grand Prix base model (3.8 L26)

Asked by Apr 29, 2009 at 05:36 PM about the 2007 Pontiac Grand Prix Base

Question type: Car Customization

I have a grand prix 2007 base model engine (3.8 L26) Is there any way I can supercharge it without top swapping it with an already supercharged engine? I've seen after market turbochargers for an L36 (2004 and under) and its basicaly the same engine but 2005 pontiac grand prix's and up are in the 2 series engines. Does anyone else know my options?

If it was my car, I would not reccommend adding a turbo/super charger without strengthening the internal components inside the engine as I believe the supercharged engine from the factory has stronger internal parts. Typically to do a significant modification and to get the most out of it would usually require upgrading other components, i.e. higher flow injector, reprogrammed PCM, exhaust and possibly so on.

What you want to do is a top swap. You'll need several parts from the L32 motor, including throttle body, lower intake manifold, cylinder heads, fuel rail w/ injectors, valvecovers front and rear, harmonic balancer, idler pullies, brackets, tensioner, etc
