LS4

As much as I hate to say it one of clubgp's members did a really detailed write up on this, if I recall correctly.
I say do it! I want to do this, but I have to get my 97-03 car first.

Click to expand...

it would be a sweet swap....just power wise there are better options (TURBO)
 
yeah, it would be for a coolness factor and that is pretty much it, you could build a 3800 motor for prolly about the same as buying the ls4 complete engine and trans and all parts to swap it.
 
I would like to see a pregen with the GXP setup... but overall the GXP sits to be the nicest riding Grand Prix made.... The ride, the interior, the quickness, the sound... its endless. I have magnaflow exhaust with the K&N intake, which was how I got it from the dealership! Turbo... Wouldnt even want to do that with the trans in these cars... otherwise the LS6 cam swap with 1.8 rockers seems to be a sick setup. Cant want to hear more plans from you guys here.
 
I've got a 07 GXP, 12/08/08 after my 2000 GTP got totaled:(:( I got to admit I wasn't sure about it I was looking for another GTP, I had a lot done to my GTP, but I came across the GXP and thought that was pretty damn cool. So I guess I will be startin' over.
 


thinking about getting rid of the 06 GT and getting the GXP what are yous guys seeing in HP gains and 1/4 mile time with them?
 
Mid to High 13's Stock I assume...they are rated @ 303HP from the factory...so I would say...maybe 260-275WHP?
 
they run a 14.1 in the quarter stock but i was wondering what HP gains people are getting with mods and 1/4 mile time witht he mods
 


pick up some of the honeycomb wheels from 97-03 bodys they are 8inch wide and they arent that much. What mods have you done so far?

16 will not fit over the breaks in the front :( I have just air intake, iat relocate, 160 stat and other bs now I have been shopping for some spray:) I want 12's but work has been bad so I don't want to blow money yet. Any input would be nice... We will see.
 
I must have missed the article on the rareity of the 07 GXP, I've got an 07 that's midnight mettalic blue, with a production date in january, I've been wondering about how many 07's were produced in this color, I only know of 2 other people with the same color on other sites, it's gotta be rare
 
I was looking at a wet system for the car, but now work is bad so I may have to hold off for a bit. The iat relocate is where you move the iat sender from the tb and I put it farther down the air intake to cut down the false readings from the heat off the cross over. The iat is also a faster reading one then stock, so it helps keep my timing up.
