I don't know anything when it comes to buying aftermarket stuff for Vettes. My neighbor has a brand new C6 and he wants to twin turbo it with this kit and wanted to know what I thought. Anyone have a clue if this kit is crap, or a legit upgrade?? I told him to go to Lingenfelter but he is on a budget.
If they make turbo kits like they make videos he may want to look elsewhere.
Gary, I recommended that he just bolt on a Magnacharger for now. At least you know what you are getting with that kit. You had/have a vette right? What do you think?
Yeah, in a motor trend i have, the LPE C6 ate the diff when launched with drag slicks on it. Wheres he gonna use that much power. +1 ont he head and cam car.
He is aware of the hood change with the Magnacharger, which is a turnoff.
Chad, I agree. A good motor package probably is the way to go. He is looking for a good 600-650hp to the wheels and that is about it (atleast for now, you know how that goes). I'm not into Vette's, but the car looks pretty good. Actually upgraded to Z06 wheels and breaks which is nice.
East Coast Supercharging has a Paxton based kit, with a single front mount intercooler setup, available for the C6. They are a very reputable company and I think the kit is around $7g. They have their own custom bracket that almost eliminates belt slip.

Buyer beware on the SVS TT Vette system. It seems to work good on some cars but I know of some Vettes that are not pleased.
If he honestly is wanting that HP -- TT is really the only way to get it for the Vettes. Understand he isn't wanting to put the money out, but you get what you pay for. LPE is really the best to go.
Go with the TTIx kit. I just switched from a top-mount single turbo to the TTIx on a destroked LS7 motor in an '03 Z06. Car ran 11.0@ 140+ at 10psi with a break in tune. The kit will support 900+rwhp and fits like an OEM application. It comes with cast manifolds (read better than the fabbed stuff). Price-wise they can be had for 10K or less. Install is reasonable. Only thing needed for big hp applications is upgraded fuel system. PM me and I can send some pics of the engine bay.
Just realized that this is for a C6...I believe that there is some work being done to make the TTI kit for the C6, but nothing official yet. If you have to do something now, go with the APS system. The system quality seems to be pretty good. My only misgiving in the base kit is the turbo sizing, which I believe are GT28 or GT30'S. They are working on fitting GT35R's, but nothing final yet.
The quality of the APS stuff is middle of the road, but FAR better then most the stuff i see companies try and pass off. They focus their marketing on a few of the higher quality components of the kit and the completeness of the system - which with all due respect is very complete. Some of the parts that get less attention they use some pretty hokey Home Depot looking stuff - but nothing that is going to sacrafice reliability.
You can trust a properly installed APS system to make good reliable power, but make sure you get it from a DIRECT APS DEALER and have THEM install it - their customer service is known as TERRIBLE in other communities and their RELY on their dealers to do it for them. If you do not have the kit installed by one of their dealers, you are absolutely on your own.
APS was actually banned from the largest Z community because they have a sales guy that liked spamming every FI related thread with APS marketing... but they got their nutswingers and AE's still taking care of business.
As much as APS as a company has annoyed me in the past, their products are always complete enough to cost effectively build safe power - which im sure is their goal. Some customers have given me APS stuff to put on thier cars, and while I am never excited about using it (pretty boring and conservative stuff) - you dont have to worry about it falling apart or blowing the engine.
Going by the video, it seems like a poorly designed turbo IMO. Unless you like the off/on turbo boost. An aggressive head/cam/headers/bolt-ons/tune will give 150 RWHP, so that puts him at about 495-500 RWHP. The LPE SC kit puts out about the same. Therefore, he is still a good 100 - 150 RWHP short. I guess you could add Nitrous to the mix.... Maybe a high boost Centrifugal blower/intercooler might be able to achieve those numbers? If 600-650RWHP is a must, seems like TT would be the best route. I just don't like the way the Vette pulls off/on in the Video. Or be happy with 500RWHP and go with a proven package (Cartek head/cam, etc...) + no hood mod, then add a little Nitrous.
The C6 APS TT kit is nice. I guess turbo sizing could start to become a concern for any of the bottom mount kits (LPE, TTi, APS) if your HP goals are high enough (over 900 rwhp). Only T3 based turbos will fit down there so HP would be limited to around 1100rwhp MAX with the biggest of T3 snails in place. Anything over 900 rwhp should really consider using T4's IMO.
