My Nephew wants to beat my Marauder

[Bradley G]

I got a Text yesterday from my Nephew who @ age 27 just went through Chemo for cancer,
He said in celebration of his last treatment he bought another Gran Prix 2006 this time a 5.3 V-8.
He asked me what mods he could do on it to make it really fast.
He said his goal is to kick the Marauder to the curb:eek:
I actually added the last part but he did say something about eventually beating me in a 1/4 mile race.
I looked on some Pontiac forums to see what are the popular mods for GP fans.
Looks expensive!

Just lift and let him win.

My stepdads friend has one but the only mod he has done to his car is 100 shot of nos :) but he did give me this link for him to sign up.

Nice car he has there. Last summer, I tried racing a guy in one of those and he wasted me!

Can't wait for the eaton swap!

The 5.3L GP's have minimal potential with just bolt-on's unless they do a heads or cam swap. The GTP's with the superchargers on them are a different story. There is a group of those guys around me that have them running low 12's and 11's with minimal work.

Yep, the 3.8L s/c V6 can be worked a lot more. With tuning, intake, pulley swap and exhaust I've seen some run low 12's with no problems. Just a pulley swap and tune really wakes the car up.

Just a pulley swap and tune really wakes the car up.That is what he had a couple years back and it had some issues with leaks and such so he traded on a car with warranty
