he made a comment that the transmission is broke, i guess the chain broken in it.
but yeah seems like a good deal, throw TEP transmission in that it would be a beast.

That is pretty cool and a very good deal...

I would pay his asking price just to yank the supercharger setup off the engine and junk the rest of the car...

guys....I am the owner of the 2005 gxp with the blower installation and it sounds like there are some folks with some questions. My phone has been filled with txt messages asking questions on the install. I am happy to help answer some questions and hopefully sell my installation so I could move on to my next project. Are there any takers?

I am very curious how you got the custom blower pieces as well as reverse rotation rotors, and what machining was done to make the LSA ports fit onto the cathedral heads. Any pics you have of the process would be great!

the rotating group you will need come from an aftermarket roots blower such as a Roush or SLP kit. You will need to get the correct side drive for the install. I believe I used a left side input shaft. The cover and drive shaft and pulley were made specifically for this installation. Use a solid drive coupling to go from your input shaft to the driven rotor. That blower Inlet was made by modifying that LSA style front inlet. I also used the LSA injectors and rails. There is some internal machining on the blower housing you will need to do to accommodate the correct airflow path for the ZR1 lid. That adapters I made were faulty crude due to the limited vertical height. The blower also gets machines to fit to power steering pump in line with the forward ports. A remote reservoir is required. That pump housing was also modified for the move along with the addition of 2 more idler pulleys to support the new belt path.

I have to ask. How has this gone unnoticed to the LS4 community? This is most likely the only supercharged version of our cars with the LS4. This is kind of a really big deal . Seems like a lot of work was done and a lot of engineering to get this all together, not to mention quite a few bucks. Has this car been under wraps since you built it, closed hood type? I really wish I had the money, its priced right for the taking and whoever gets this I hope they tear it apart and post some pics so it can be duplicated . Good luck with the sale, post back here and mention to the new owner about this forum please. Cheers!

FWIW I am the one who bought this car.

The trans just needed a new input drum which i had laying around in a parts trans, so $35 in gaskets/filter and its up and running. Had a few other small issues i had to take care of (brakes, wheel speed sensor wire, etc...), and been playing with the tune a little as well. I picked up a stainless ZZP downpipe for it as well as it still had the stock one. Once i get the tune updated to my liking and the new downpipe on I'll throw it on the dyno and see what it does.

Good job on the purchase, sounds like you have some experience dealing with this transmission already so you are way ahead of the game.Hope you are active here, post some pics of the car as you progress with it also. Sounds like the car found a good owner.
