Twin Turbo C5 So does anyone know of any twin turbo C5 kits out there?
I'm aware of the Lingenfelter kit but it seems a bit high at $23,000. Are there any turbo kits that compare in price to like a $7,000 Magnuson kit? STS is talking about a custom twin set up for about $8,500 installed and tuned. Twin T3/4s, intercooler, injectors ,pump, tuning, etc. What else is out there in that price range that includes tuning and install?
Thanks.

Turbo tech makes a pretty robust kit now for the C5's.
The Stage X
http://www.turbotechnologyinc.com/co...er_systems.htm
I have seen a car run with the kit on it, pretty cool and transparant. When I seen it it trap over 137 mph I had to check it out. Based on a standard C5 weight it had to be making well over 700rwhp. Rumor has is that it was stock displacement and pump gas driver. Never did talk to the owner.

TTi X I don't think this kit is very proven at all. There are about 5-8 kits being built and two or three that have been re-built. It is a new kit that has yet to run a consistant number or make it thru a complete season. If money is an issue get the TTi stage one and you will have a street turbo car that isn't that fast. If you have some cash sent your car to LPE and have a proven consistant turbo car. I am not bashing the TTi X but it is what it is, and proven it is NOT. Trying to save a little cash could cost you big cash later on think it thru before you decide.

Thats Odd,
I was investigating going to a C5 and was looking at the kit late last year. I know I had seen several posts on multiple forums and there is atleast 20 of the X kits out there. I have not seen any posts about "rebuilds" only a couple of small fitment issues. It uses cast manifolds,bearing turbos,stainless hot parts and gates so I cant imagine any issues. Also it appears to me the core design is based on the Stage I kit that has been around for a long time that you concider proven. Can you point me to any real reliability issues? C5s are getting real cheap up here.

The Burgundy Vette steps out and moves. Pump gas daily driver to and from the track. It's at home on the street, the highway or the track. It's just a fun car.

Verdad Gallardo There are many more than 7 or 8 Stage X kits in production. Keep in mind that not everyone with a turbo uses online car forums..
The State X was out last year. I personally know several people with the kit.. All of them are happy with it..
I know the guy with the Stage X that did the 137 MPH pass mentioned above. That is a 346 ci motor with very average 270 CFM flowing heads and a mild turbo cam. That was his first and only pass of the day (kicked out as he doesn't have a roll cage). That pass was also medium boost (13ish).. The Stage X will flow 18 #'s on a 346 ci!.

I was through making power before the Design was maxed out on my car. Granted we only made 740/725 at rear on what I have been told is the most conservative dyno being used by a Vette Tuner in California. The place that tuned my car last year had a Grand Opening, with Free Dyno time all day..probably about 30-50 cars hit the rollers that day. I quit running the dyno after 2 hours because it was getting old. Most people who dyno'd there cars were dissappointed because they had just dyno'd at a local shop down the street....about 20-30hp more on those other dynos. The main part to me about the dyno is getting ZERO KR and a GREAT AFR...the power should be a result of that.
So take it from a TT owner or other owners not a bunch of people with fluff information.
I'd have to recommend the TTi StageX kit. I don't own a C5TT... so shame on me for even THINKING about commenting

No offense Shinobi, but people that "know" turbo cars don't pimp dyno numbers by saying they ran on the "most conservative dyno" around. It's like claiming more power from a Type-R sticker. That is "fluff" information by any standard. 
A dyno is just a tuning tool and everyone all ready knows that different dynos will give you a different number under all the same conditions. Claiming to know what that difference might be on any given day would be pretty silly.
The PTK kit may turnout to be a good option for some and you may have a nice setup in your car now, but until it's got some track times and the MPH to back it up the dyno numbers, the sheet is still just a nice piece of paper.
I don't have to see the dyno sheets, or own a car with the TTi X kit to know how well they run. I've watched a few of them run at the track and on the street. I've lined up against them at the track. That's a good enough test for me to speak with adequate experience on the matter. I'll look forward to the opportunity to speak highly of the PTK kit once I see one in action too.

To answer the original posters question.. About a turn-key TT for $8,500.. The answer is no.
You will need to add fuel upgrades (injectors, pump, etc) + drive line. I don't think you're going to be joining the TT club for under $15K. Sorry

a car should dyno the same corrected numbers also. I like number becuase that is potential, it takes out driver error, traction, suspension, you know you have the power, then you just gotta figure out how to get it to the ground
