APS which kit?
Not sure if it makes any difference or not ,but I just received an e-mail from Phil at Dyno-tech concerning the C5 twin turbo kit from APS. He told me that they use the C6 kit for the C5 because the C6 kit has duel ball bearings to support the main shaft in the turbos and the C6 kit also keeps the car emmissions compliant. Has any one heard about this? I know APS is running a special right now, but is this the kit that you really want? I still want to go with APS, but just a little confused and want toi do the right thing

Peter from APS comes on here and says he doesn't even like the ball bearing turbos he uses in his OWN C6 kit.
WTF???
I don't know.
I'd just go with the ball bearing turbos if I ordered any TT kit.

The C5 kit uses T3 flanges vs T25 flanges you will want the T3s and the new turbos even though they are non ball brg are going to work very well. There is no doubt a dual ball brg turbo is a nice feature but I think a lot of people are overly concerned about this. These turbos will probably live longer than most will own there vehicle for, plus we have 350+ cubic inches of displacement. So there will be very little differnce in spool time it may actualy help the car hook up better, and I doubt if there is more than 150rpm difference.

As stated~ we use the C6 Corvette TT systems on the C5 Corvette applications we build here for many reasons: We prefer the dual ball-bearing turbochargers of the C6 Corvette turbos over standard C5 Corvette journal bearing designs, the factory brake cooling ducts of the C5 Corvette are retained to be fuctional using the C6 Corvette TT system and the C6 Corvette TT system allows high-flow catalysts to be implemented in the exhaust stream within the factory heat-sheilding of the exhaust tunnel to maintain some kind of emission compliance, where the C5 Corvette system does not. Lastly, the Garrett turbochargers have proven themselves over time in many of the LPE car's built since 1999.
But doesn't the C6 kit have smaller turbo's due to increased compression and higher hp on the C6's?

The turbos used on the C6 Corvette TT System are the exact same units that was first intially installed on the LPE "650 packages" a number of years ago, which spool up to speed by approx. 2200 RPM- they are not intentionally produced "smaller" for any application. The C5 Corvette units are a bit larger, at the expense of a longer spool-up time of approx. 3200 RPM.
We chose to use a turbo system that encompasses the best overall performance area under the curve for the street applications they were intended for. The cars are overall much quicker, they are emission compliant, they retain the brake cooling ducts, the fit/finish is excellent and they spool-up very quickly.
I've had extensive, real-world, hands-on training/experience with turbocharging the Corvette vehicle platform when I was with LPE and we spent a *LOT* of man-hours sorting out what worked best overall.... I've relied on that experience to build highly powerful and reliable TT package cars today now that I own my own business.

Phil posted that the larger turbos spool at 3200 instead of 2200. (1000 rpm difference)
After driving a few LPE turbos,
I got to tell you that the turbos spooled FAST and was PERFECT for the street.
The lag was virtually non-existent.
Even if you gave up a little on the top end,
I'd still choose the smaller turbos.
Especially for a car that is going to see most of it't time on the street.

Don't the APS kits delete the Air Pump from the C5's (I'm presuming it's the same on the C6 kits too), thus making them non-emissions complaint anyway???
As for the spool, I'd almost prefer a little later spool time. Having the turbos spooled and cranking out a ton of TQ at 2200 RPM means a lot of tire smoke if you're not pretty cautious. Having them come on at 3000ish RPM give you more of a chance to be moving when the power kicks in and a greater chance for traction.

I agree with what you say . Area under the curve is key. 
What do you think drove Peter and his team to spend so much effort in redesigning the kit for the C5? (unless the thought was that a re-designed cheaper kit would sell better in the C5 market vs. a more expensive option for the C6 boys).

That is correct. However, we implement the A.I.R. injection into the C5 application as another effort to maintain emission compliance. The standard C5 TT system does NOT have this, nor does it have any room under the car's tunnel for catalyst installation without *major* exhaust/wastegate re-location fabrication.

Believe what you wish..... We have C5 systems here now, as we placed a huge order just before the shut-down and just before the sale many of you participated in......
