The Billet 6262 & 6765's we're referring to which are the subject of this thread also have great spool...but 'relative to high-output turbo's'. They won't spool quite as quickly as a 35R DBB... but can make much more power...

GT35R DBB... for the power level you just referred to thats the perfect/fastest spooling turbo... excellent for road racing, auto-X...

It is??? News to me. Goodfellas was actually built in IL. Not a single thing to do with precision. A guy named Jess put it together for me. He left that company so I use another. To be honest I have a few places that can make them. If there is one thing I don't like about precision it's their unwillingness to do anything that isn't off the shelf.

My intakes are ported as big as one can go without going j-port or bridge. I mean big. A little bit on the exhaust. I guess the exhaust is the deciding factor when turbo spooling is consideration.
What do you mean by nice power? I have nice power now. I want a little nasty power.

Well I'll let ya know how the billet turbo is. I just ordered the GT42R 71mm Billet from Garrett. It will take awhile to get as they are backordered.

Nice choice Ernie. I had that turbo on order until Precision decided they didn't want to produce it in JB anymore, and I didn't want to sell my kidney for the DBB version. Looking forward to seeing it in action.

Why you ask?? because those turbos are cast version wheels just made in billet.. they do not use the same aeros as a PTE wheel.. Its the same Bulky Cast wheel in billet.. Not a turbo i would choose personally.. Just my advice..

Good luck with that turbo.. The wheel may be billet but you will NOT see the gains you see from the Precision lineup.. Just my .02..

You guys should do more research. The billet wheel turbo's do make more power. For instance, the 71mm GT42R will make the power a 74mm would. Also Precision doesn't make their own wheels. PTE and the other companies don't have the R&D facilities to actually test a product before release like Garrett does. THIS is why the Garrett is the better turbo.

"No noticeable gains in performance can be seen when testing a machined wheel vs. a cast wheel of the same design."
The only way to increase power potential of a specific compressor wheel is to change the aero, which is to machine the compressor blades longer (closer to the base) since billet wheels are stronger than cast.
Where is this research stating that Garrett has changed their minds about Billet and in such have released a new 71mm wheel?
Nowhere on their site does Garrett offer a Billet version of their 71mm wheel

Well, according to Garrett: http://www.turbobygarrett.com/turbob..._Machined.html
"No noticeable gains in performance can be seen when testing a machined wheel vs. a cast wheel of the same design."

I was simply suggesting that you are missing the boat by not using Precision Billet lineup.. I dont care where they are made or who makes them for PTE.. The bottom line is PTE turbos are making more power Lb for lb than any other turbo on the market.. Try making 920whp on a 67mm t3 with any 4cyl car.. IT AINT HAPPENING..
Also, anyone who believes a BARELY lighter Compressor wheel will increase spool is wrong.. The turbine wheel dictates the spool based on turbos with the same size compressor.. below is an example of why the billet turbo from PTE is superior in aero.. Look at how much more surface area is on the billet turbo.. Thos 2 turbos are identical compressor size yet 1 makes 180whp More.. If you take that 6765 and just change the wheel to billet from cast there is NO SIGNIFICANT GAINS IN HP.. The billet turbo below has shown over 20% more HP.. You cannot deny PTE's new Billet Lineup..

Ive spoken with 1 of the lead engineers at garrett and their main issue with competiting with Precision Billet Lineup is they must pass OE specs.. That is not something that can easily be done.. Luckily for PTE they dont have to follow the same guidelines in creating monster turbos.. As much as Garrett would love to create a RACE turbo it still must be a turbo that can pass OE Guideliness for Stress and reliability.. And yes the have tested several companies " Race " turbos at OE levels for reliability and they blew apart and sent parts across the test room..

Im gone for a day and I miss a good discussion.
Its not hard to get it in JB, you just hafta know how!
Yep, its rated for about 900hp. Not any advantage to the billet wheel!
They dont always update their site, but its available. Ive seen it already.
Like Mike said, its the updated aero designs. You could gold plate a compressor wheel of the same design but it wont make anymore power. PTE doesnt machine their wheels, but they did design them in house. Engineering software these days is amazing 
Their 71mm billet is rated for 900hp, the 74mm is rated for 1000hp.
But we know very well that you can beat the crap out of the PTE billet turbos and they will hold up just fine.
They already have some out. 71mm, 94mm, 98mm, 102mm...

This is correct.. In 99% of applications you can beat the **** out of them without an issue.. I dont know too much about OE requirements and what they did to the turbos to cause them to come apart but i might be abuse thats seen on a Cat truck motor that we would never use the turbo in that application anyway..
