I can get my hands on this kit pretty cheap. And need to know how much RWHP i can get with this kit.

Im also getting a new engine that can handle upp to 35 psi.

So how much boost pressure can the turbo handle?

If there's eny one that have eny info please let me know.

Oh and it's going on a FD

700+ is what I found. Yikes!!!

45psi

The greddy td07 25g is capable of 550-600hp. From there you would wither need to go with a t7833d or a t8833d. I have all three turbo if you 7wish to buy one. Email me for pics. cwebb77083@yahoo.com

I say good luck getting that kind of HP out of a 25g

Sorry for the bad info. I *did* know it was a 25G... I typed Greddy TD-07S in google and looked around. Found a few sites with cars sporting the turbo. One of them said 700 something... Sounded fishy, but figured I'd share since it's all I could find on the setup...

Greddy:

T67:
The T67 isn't used on supras very often, its a TD07-25g turbo, more
commonly used on MR2s... its capable of right around 600 rwhp, and spools
similarly to a T66, so most people choose to go with either the T66 or
T61. Again, on the upper limit of streetability.

Ok, i think i might go for it. But how much psi can the turbo handel?

can it take 28psi without braking?

jantore- Where do you plan on running 28psi? Drag car? For the street most don't run over 18psi unless there is water injection involved. Once you get past that much pressure some kind of race gas is needed.
I know on my TD07-25g with a 17cm turbine housing I have enough fun trying to keep the rear tires from spinning at 15psi, can only imagine 28psi...

jdhuegel1- I thought the T67 used the TD07 comp housing and 25g compressor but used the TD06 turbine?

sub-zero- how much hp do you think the 25G is good for?

45psi- you are talking BHP, not RWHP right? 550-600rwhp seems a bit much for this turbo.

45psi

I mean the td07 25g is capable of 550-600 crank hp. Sorry for the confusion. It would not be necessary to but 28psi on this turbo. If your looking to hit 450-500, 20 psi should do it for your car.

jantore

setzep the 28 psi was the max i would want to push out of the new engine. Im building a drag/track car with alot of rwhp.

Got a freind helping me. He got a 750rwhp supra.

So i think i have gotten the answers i need. The TD07-S won't give me the rwhp i wan't.

Then i might go for the SR motorsport stage 5 turbo kitt. But it's 1500 US$ more expensive. But that's peanuts

45psi

I can have you a t78 or t88 within 2 weeks for 2800 US dollars.

jantore

thanks but no thanks, did just get an even better deal on the TD07-S turbo kitt, so il go for it

Could very well be. I'm not sure... Just did a little looking around and posted what I found. Apologize if it's not accurate.

Is the TD06 and TD07 turbine that big a difference? I'd have never guessed if so. There are so many different sizes I hardly know what is what anymore!!

ludeowner

I'm not sure what the size difference is, but I remember reading a long time ago on another site that the TD06 turbine is equivalent to a T3, and the TD07 is like a T4 turbine. So a TD06-25G might be like a hybrid T4/T3 turbo while a TD07-25G would be like a straight T4 turbo.

setzep

One of these days I'll get around to taking my compressor and turbine housing off to take some measurements. If I remember right the TD07 turbine is just a hair larger than a p-trim turbine wheel.
