Help me understand this Turbo - Paging John @Vitesse
Okay, so from what I know of this turbo, is that it is a modifed Vitesse Stage 3. This was on Special Tool's car for his 577hp dyno glory run. The goal is to run this on my 3.3 Hybrid Stroker build, with a 500rwhp goal. I had this turbo apart today and measured what I could. Any further help and opinions are welcome.
Comp housing is Garret A/R 0.60
Comp Inducer - 61.38mm
Comp Exducer - 82mm
Which calculates to a 56 Trim.
Turbine housing is Turbonetics, 8cm^2 and also a 10cm^2. The 8 housing has a stamp, but the 10 does not. Any way to make sure, can't see exactly how I could measure that.
Turbine Inducer - 64.2mm
Turbing Exducer - 56mm
According to my math the 8cm housing makes for a 0.57A/R and the 10cm makes for a 0.73A/R.
Supposedly there is other porting work, titanium shaft, ect.. John do you remember any other details? Is this turbo cartridge or DBB?
Opinions guys?

Will,
Between 2004-2006 ST used different turbos. These turbos were built and modified to meet ST's specific goals. Some of these turbos were 1 of. I don't think this was the turbo used for the 577hp run.
Back then 2004-2006 we did not use DBB. It was a few years later before the DBB became an option.
The #10 turbine housing does not have the "10" visible the same as the "8". It just have a mark (where the "8" is on the #8 housing! If you send me a picture, of the mark, I can tell.
Regardless, depending on your goals, this turbo may not be a good match for an all out 3.3L. If you want to get the most performance out of your 3.3L, you will need a larger turbo.
A 3.3l 951 sounds awesome. Hope you start a dedicated build thread.

John, message me a good contact. I will snap a picture of the turbine housings and send them to you.
Appreciate your input here.
A dedicated thread will be started soon, as I hope to have the block and crank out this week for machine work.
