Not too sure on this, but I would say the computer and wiring harness. Plus
possible a dash change if there are extra gauges (like a boost gauge) or
other idiot lights.
OR, don't they make aftermarket superchargers for the motor that is already
Seems like a waste to me...BUT you gotta love guuys who like to throw money
at thier cars. There are a couple guys here that are really knowledgable
about the new OBD computer systems. You could ping the alt.trucks.chevy
group and get the gearheads over there a shot too.
I would go with the aftermarket Paxton and be done with it!
Why hop up a Grand Prix (I don't care for the '97 to '03 GP styling)? If I
were him, I'd sell the GP and buy a low mileage cream puff '81 to '87 Buick
Regal grandmother car and put a Garrett turbo in it, a new chip, and some
nice rims (make it a Grand National clone), or drop in a small block Chevy
with some hop-up mods in it. More smiles per mile plus it'd hold its value
longer. The '81 to '87 Regal is one of the best styled cars in GM history
in my opinion (better than the Monte Carlo, Olds Cutlass Supreme) and has a
lot of hop-up potential.
