They take very well to mods. They have a more efficient blower, and an arguably better bottom end and heads. Things to watch out for:

Fuel Injectors - Smaller than 97 - 03 GTPs and max out around a 3.4 - 3.3 pulley

The fuel system also isn't pressure regulated meaning pressure stays constant rather than bumping up 1lb for every lb of boost.

So, if I want to run smaller than 3.4 I need bigger injectors? Is there a way around the non pressure regulated fuel system? Can you fix this or work with it?

All these guys are on stock injectors.
PCM's are now good to go. (supposedly)
I have the compG so the ride is pretty stiff.

Yeah.. They say you can drop to a 3.2, but that is maxing out the injectors.

Dont get me wrong I know that will happen. I just wanted to show it can be done w/o any issues. Just to be safe stick with 3.25 as the lowest on stock injectors
