yeah and the oil-less setup is alot more, I beleive the retail on a billet 8079 TBB oil-less was around $2400 shipped last time I called, but dont quote me on it! I get them for cost though, so ill have to check i didnt write it down

So what kind of pricing for the oil less 7271 with basic compressor wheels and like with. 1.00 a/r
For just 600-700rw for remote mount
I just got real interested
I hate e oil pumps and mechanical scavenge pumps cost more than the conventional turbo itself
I would def pay to run a reliable remote setup without a e oil pump

$2400 is outside my ballpark! I picked up my pt88 for $1270 shipped new in the f.s. section. Looks like i'll be sticking with it and spool wont be an issue with 10:1 cr & 402" i'm sure. Thanks for the info. Maybe one day when the budget isn't so tight i'll have one.

like I said thats retail price. Case in point I just got a new billet 6768 TBB but with oil, and retail was like $1800, I paid $1170 or so. I think the 8079 oilless will be around $1800 for me to buy but cant gurantee it till I call in

Hmmm intersting two 70 mm up front on a vette 1000 HP +. I want to see these things punished befor i drop a dime. I email them with no response on how much heat they can handle. This wuld be a great solution to my dreams of a tt vette rearmoutn for front mount. I HATE PUMPS!!!!!

I've had pump fail before
Not a good thing due to electrical gremlins

well im waiting on repsonce for them, but might as well ask here as well, what would be a good oil-less version of a T70 with a more conservitive .84 or .91 ar? Im trying to do a rear mount turbo and if i could get one of these oil-less turbos that would be AMAZING!
THeres so many different kinds of turbos on there website i dont even know where to start. No need for one of those race billet ones for me, but does anyone know what would an oil-less would run equal to or better then a T70?

what specific t70 are you looking to compare to? an old school T70 Q trim would get beaten handily by a 6768 comp turbo, while a 7068, 7071 would make a solid 100whp more. remember that a TC76-TC78 turbonetics would be compareable to a 7268 comp, so you can go from there.

I would suggest a CT43- 7071 with a 1.0 AR divided housing. That should spool similar to a old T70 pretty easy, and gives you the option to add a spool valve for full boost at 2500rpm in the future.

Just an example, I have a billet CT43-6768 ball bearing on a stock 2jz with a 1.0 A/r divided housing and a spool valve. In 4th gear i can floor it from idle and have 20psi before 3000rpm and it will make an easy 600+whp with very low backpressure

Go with the larger ar. Using a thripple ball bearing will put way ahead of the game as far as spool time.

I was under the impression that with rear turbo settings, anything over .84 A/R will lag pretty bad.
I was looking at this one for starters. what do you guys think?

i am glad to see such a good response on here about these turbos.my comp looks awesome i hope it performs as well as it looks.

I'm very interested in the oil less versions. I've had some people come to me to build em a remote setup. But after that last pump failure I'm reluctant to build another. Buy these oilless units change my mind.
If u do the math the oil less turbo costs less or comparable to conventional turbo with e oil pump and less headaches and chance of oil failur.
Fu(k the turbo, I'm worried about the engines bearings in case of oil pump failure.

This thread is relevant to my interests....

I really want to see how these hold up.

+1 on that. I want to put together a rear turbo setup the first time right so that i dont have to hunt down oil leaks and have to worry about check valves and blowing smoke out the tailpipes and all those other horror stories i keep hearing about lol

Interested to know if they can make them in T6 flanges.

Would any of these happen to be compatible w/ the TD06h housings seen on the APS twin kits?

Grr

iTrader: (2)

if you send them your housing im sure they would be able to tell you if they can machine it to work, I have thought about that myself. Otherwise they cast their own housings so it wouldnt be too hard to make them new

I believe that number is for a stock heads/cam/cube motor, not really a universal rule for ALL rear mounts.

Apocalypse

Go with the CT34 7071. If you compared it to a T70 there really isn't any comparison. The It would spools faster and make more power than a T70.

Very interesting. I'd like to see an 85mm oil-less unit with a 1.16A/R with a spool valve for a rear mount .
