Thread: Should I Buy a GTP or GXP

I'd say, go with the GTP every time, unless you MUST have a V8.

With the prices I have seen on GXP's, you could probably build a 400+hp Turbo GTP for less money. The insurance for the GTP will be cheaper. The GTP will be better on gas. I would also imagine an L67 will be cheaper to maintain and last longer, all else being equal.

As for the transmission... yes, it has to deal with more torque, but also, I've heard many times that the aluminum block LS4 transfers heat to the transmission more readily than the iron 3800.

I'm not saying the GXP is a bad car at all, but for 11K ... you can almost get a real muscle car with RWD. The GXP just doesn't seem like a good value.

The LS4 has DoD and doesn't require premium fuel, and has a higher EPA est MPG.

Other than that, get a GTP

Bro the ls4 most certainly does require premium fuel. I ran 91 and even 89 for awhile until I knew and saw more KR then I would of liked. Premium fuel...not really much of anything
