You may want to checkout this artical from hotrod about the Caddy Hot Rot Fabricator modifications - including turbo kits up to 2000HP

http://www.hotrod.com/techarticles/e...rth/index.html

They say the engine will turn a reliable 8500 RPM and with cam/head work can make 500HP+ at 7700RPM.

Here is some guy who puts Northstar'* Fiero'* - not sure if they also mod the engine.

I am glad to have found your site, the first thing I installed was the K&N filter and a set of Flowmaster mufflers, what a great sound!! I have been corresponding with Domestic Performance to get a set of headers and a computer upgrade, both I was told are on the horizon. They also are looking into making me an air intake upgrade. I have searched CadillacForums for more advise with no luck. Any other idease would be greatly appreciated. Thanks!

Scott, Any word on PCM for the GXP'* yet?

Scott

Out to the side of my posts it says LE member and I have a GXP, can't figure out how to change that? Any help?

Its a post count ranking system, its not indicative of your car.

Thanks Jim! I guess I just showed you all that I am the "NEW" guy to the club. Does Scott from Intense have performance parts for GXP'*? I would like to get another source for upgrades, the only one I have found so far is Domestic Performance. So far, I haven't had any luck getting much of anything because the car is so new. I want to put my car well into the 300 HP range, just need to know where to get the parts?

Anyone have any luck finding more ways to upgrade the horsepower on the GXP' yet? Haven't heard back from anyone lately.

1) K & N Air Filter - part number 33-2063-1. The folks over at Edmunds.com say this is an exact match and will fit our cars. I haven't confirmed this yet, but plan to order one soon.

2) PCM - I don't know how much opportunity there is here, but we'll start working on this one next week, and we should have PCM'* available by the end of June.


Today I added 33-2063-1 K&N filter: BadSSEI, I too noticed that when I first compared my 03 SSEI to 04 GXP on take off there was no comparison, SSEI hands down. Then I realized that you couldn't just stomp on the peddle, you had to ease on it. Today, with more air added and turned off traction control it'* real close but a different take off. GXP
glides 0-60 whereas SSEI jets 0-60. I don't want to mess with the computer just yet. Let the newness wear off some.

Thanks
