APS TT turbos
Figured I'd post here as this gets more traffic. I'm having a hard time finding any replacement turbo's for this kit. So looking to see if any of the forum members have some laying around they would like to get rid of? Original replacement turbo's or upgraded ones. TIA!

APS C6 (base, non Z06) kits came with a GT3076r CHRA and custom hot and cold side housings. You can order a replacement CHRA through any Garrett dealer, but if the housing is damaged, you have bigger issues.

Did APS not use like a TD05 chinese clone or something for the cores ?
how badly cracked are the housings ? Often cracks never really do any harm. Is that the only issue with them ?

Precision sells replacement turbos for that kit and has there own exhaust housing they cast back when DKT was trying to sell them. Some of them are a little different depending on which kit you have, but found they could fix you up with just about any of them. I don't use the whole kit, but I do use the manifolds and DP's I run the Precision 6766's

I get that, but apparently APS changed the kit a few times so you cant assume everyone has the same parts. One of the many reasons I got rid of the kit.

I believe early on they used a Mitsubishi CHRA as well as the Garrett parts and a mix of others. That's why I prefer to confirm part numbers and tolerances before saying something will fit.

Just to clarify because the internet becomes a resource of stored information, the APS C6 kit only ever used a Garrett 3076r center section. Similarly, their C6Z kit only ever used a Garrett 3582r center section. Greg is absolutely correct that there is/was a Garrett 3076r center section that was easily replaced into the APS C6 housings. Unfortunately, 10 years ago Garrett had a bunch of versions of the 3076r center (700177-7, 700177-10, 700177-11, 700177-12, 700177-13, etc..), although not sure what they offer today. They did vary by slightly different compressor wheel and turbine wheel combos. A little bit of google searching of the 700-177 lineup would show lists of the variances in Compressor and Turbine inducers/exducers.

Not exactly what I was saying but I would agree if you simply look at the one GT3076r option on the garrett website you would not get the scope of how many GT3076r CHRA's actually exist. For example, ATP turbo has 9 different options of CHRA for GT3076R on their website today. If I bought a 700177-5010S from them today, it would match up with a 700177-0010 from 1999. Same would go for a -5011S and a -0011. The part #'s have evolved but still cross reference and have the same wheel specs. I should be heading down to Orlando in a couple weeks and will pull a set at Next Level Performance and measure the wheels to figure out exactly which 3076r cartridge APS used. I think he has an old take off set and a new set there I can look at and update back in this thread. My guess would be -0010, or new part# 5010s. Maybe Greg has some paperwork laying around still showing which he purchased as replacements.
