APS Turbo Specs.
I've tried to dig up this info, but I read in a magazine that the Yellow Drifting Z (I'm sure you've all seen this yellow/black Z it's run by some guy that's famous blah blah blah professional racing blah blah blah . . . ) and it said he had the APS TT kit and it uses GT25R Ball-Bearing Turbos.
So they are GT25R's? I asked Peter from APS and he said he didn't know the specs.
Thanks

Any thoughts?

With certainty, the cartridge for the ST setup is a standard, off-the-shelf gt35r (aka gt3582r) cartridge ($970 shipped from AGP Turbo).
Can't ever seem to find any documentation on the housings, however.

The Single Turbo kit uses a larger Turbo then? Interesting they would do that . . .
First of all we need to find the housing for the Twin Turbo kit . . . . compressor is probably (like 99.99% certain) custom-made to APS specs. as well
Thanks guys.

Going by the trend . . . GT35R housing hybrid for the Single Turbo . .
GT71R Hybrid for the Extreme kit . .
If the normal TT kit uses smaller Turbos than the single, I'd say something like a GT25R Hybrid? Using the housing of a larger Turbo . . .
Thanks for all of your help. I hope to crack this mystery soon.

The smallest unit Garret makes that flows 50 lb/min or more is the GT3076R. Not even the GT2876R or 3071R will come close... GT3076R map attached also..

Hmm I don't see any turbos in Garretts catalog with the same A/R config on the compressor and turbine side that flows over 50 lb/min. They could be using a smaller compressor housing and machining it out but that would be weird. it would increase the A/R of the compressor no doubt. Still the highest flowin GT28XXR compressor Garrett makes is only efficient to 48 lb/min. Not over 50. If someone measured the inducer and major diameter we would know for sure.

That said, I pretty sure someone was a shade over 700whp on stock APS turbos, marluci (sp?).
