Man this thread is full of poop. 35R 1.06 T4 out performing 500R's, 500R's not flowing as much as 35R's 6262's being the best thing going etc etc. About the only thing I've seen that makes any sense here is run the .81 housing not the .96 from scorpion. The rest is just conjecture on most peoples part. I'm keeping my judgment till I have some more 62 feedback. The billet stuff is nice but if your not going to run higher P/r's then it may not be the big end all. Put simply so far from what I've seen it produces no more extra power and doesn't "hit" as hard at moderate boost levels (Comes on smoother). That is on a very apples to apples comparison more so than many I have seen so far. How apples to apples?? Same engine, same manifolds, same exhaust, same exhaust wheel and turbine housing, same fuel system, same IC.... it goes on. It dynoed no more power, came on a bit smoother or less aggressive, but didn't drop off up top. Everything was logged as far as temps and conditions go. On track comparisons so far have been showing little if any improvement against the other cars. But other track events will give more data shortly.
The comparison was done on a 35R circuit car. We had precision upgrade the 35R comp wheel to the 62billet wheel. (they offer this) To try and pick up a bit more efficiency and ease of install. Again it showed no difference all the way up to 23psi other than it was less explosive to come on. Even AIT's stayed pretty much unchanged. I do have confidence though that with the 65 turbine (or even possibly the 62) and a T4 housing on the back side it would perform better than the 35R T3, and better than a 35R T4 at anything over 20psi.
So in the end at this point here is what I have to offer to this.
I think they a good turbo's.
I think they are proven to make power.
I think the benefit they offer is bigger power in a smaller lighter more responsive setup. (ie potential to make 42R type power in TO4Z size frame.)
I think they are good if your planning on running 20+ psi consistently.
Also as I said I am holding out on my full final judgement as one apple doesn't make a pie.
Yes elliot, it is my understanding garrett screwed precision, the same way they screwed my friend two years ago who was the biggest MD in the country for over twenty years. It was all political bull.

Be interested to see what kind of power curves you guys get.
I'm pretty glad I stuck with my 500R.....with the new engine, new portwork, and tighter setup (ie no exhaust leakage) my spool time is much improved from before

Well, who really knows if it's an upgrade? Sometimes the newest, 'best' things aren't all they're cracked up to be.
I stuck with my 500R because in my personal experience, it's been a bulletproof and reliable performer. I was told most of these billet turbos are manufactured in China, and that was reason enough for me to take a 'better safe than sorry' approach.

Plus don't knock something just because it's new. I think that the idea behind getting more "fin area" due to machining is worthwhile to test out at least. No matter which way you look at it, if you can effectively and efficiently produce more power with a smaller overall sized turbo, why go bigger? I can understand people being skeptical about it, so we need to see some solid numbers thrown down.
And yeah, everything else is fabricated and assembled in the US I'm pretty sure.

I was just thinking of this thread when i happen to check back on the forum to see it had been bumped up again* 
...after recently being witness to a couple of different Supra and 2JZ powered vehicles putting down ~850rwhp with a single T4 Billet 6765 with the small'ish "S" comp cover at high boost I couldn't help remember thinking what this beast of a turbo would do on a properly worked 13B w/ a large street port or HB with Q16 & A/I at high boost (33+PSI)!?!? I have no doubt this turbo could put out near GT42R power levels only with SIGNIFICANTLY better response and area under the curve... The billet 6765's litterally have road course capable response/boost characterists but with straight-line only/drag strip power potential! Looks like you may have your cake and eat it too...
Now for the love of god, when is someone here with a fully built 13B with a big fuel system gonna slap one of these suckers on and test the it on a rotary already!?!?

Now you guys have me wanting to pull the trigger on a billet turbo 
I'll get some dyno #s out of the 500R and take it from there. I definitely need something road-race reliable, I plan to spend some time on Thunderbolt Raceway soon

Correct me if I`m wrong though, but the 500R is perfect for what you intended it for, 500whp road racing right? Yeah, the billet might be able to do more, but it doesnt necessarily mean it can do it more efficiently, with equal or less spool, nor is it the turbo for everyone, just a new option. I like to think that its like when the GT line came out for Garrett, was it the perfect turbo for everyone? no, but it is an improvement in the right direction and presented that many more options. Ill be running a billet 67 hopefully before the end of summer and Id like to see what it can do for the 550-600whp range if everything holds together.

May seem a stupid question but here it goes. I am finally getting tired of the twins I guess. I have been reading about singles and there are so many options, especially with hybrids. If I go single I figured I may as well try billet. Does anyone know how the spool on these billet turbos compares to the 99 twins?Maybe some recommendations on size/ A/R ratio? I am looking to make between 425-450 rwhp with the fastest spool I can get. I appreciate any input and dyno charts are appreciated.

for that power, a plain old BB 35R would be more than enough, and likely cheaper than the Billet version. I would imagine spool would be better on the Garrett too, being less surface area on the compressor

I realize the billet is more money. I'm not really worried about that aspect. I just want a turbo that spools as soon as possible and can provide the 425-450 rwhp. Basically I figure the smallest turbo that will flow enough for that power would be fastest. I have read about hybrids spooling faster. Like the t3/t4. It seems from reading this thread that the billet allows more flow at high rpm due to the thinner vanes. Thus more flow from a smaller turbo is possible. My eninge has a very large port so it will flow alot of air and I think may be too much for the stock twins.

What do you mean by nice power? I have nice power now. I want a little nasty power.
