Greddy T-67 25G VS. HKS 3037S

the 35r can suport@650whp at its utmost limit (if the engine has the works i.e. cams ported head, standalone)
the greddy t67 is a mitsu 25g hybrid @500whp (maybe 550 at it's utmost limit)
IMHO the t67 is easily compaired to the 3037s as far as power goes. The 3037 gets the edge with the ballbearings. At a ofset in cost ofcourse.
Highest for the 35r off the bottle.
Marco passante 590whp
EVO III down under 575whp
AMS 35r varient 615whp
Highest 25g off the bottle
Jun 565whp
Norris design 575whp
Earl hinds 600whp
Havent found any high numbers for a 3037
sr20 boards car made 507whp
heresay on talk board 550whp
if you have a link to a powerful 3037 car please show us.

there is a guy on the mr2 boards that made 615 whp with just about everything under the sun and 25psi on a 35r. I think he could squeeze a little more out of it running higher boost.
I have or zero experience on the 3037s. Probably because of price.
My comments were more geared towards the 35r
I was unaware of those cats making 575 to 615 whp on the t67.
WOW impressive, learn something new everyday.
I am assuming were on the 10cm^2 housing?

The 3037s is like a supped up 50trim. Nice but overpriced. The turbo I would like to try is the hks3240. But man the price is stupid.

Thanks. I haven't decided on anything at this point.
I think I need to post a new thread for myself.

Thanks for the info. I appreciate it.

Again, you state that journal/thrust bearing turbos are more reliable without quoting any documentation.
JUN has a well documented relationship with Trust/GReddy. I highly doubt that they are going to state that HKS/Garrett dual ball bearing turbos are better than the Trust units they use.
Garrett Dual BB turbochargers power most of the top WRC, CART, and LeMans cars. Several top Import Drag cars also use Garrett turbos, including the NHRA Sport Compact Hot Rod Championship won by Marty Ladwig with a GT40R. The drag racing turbos are most like the turbos one would by off the shelf. More info can be found at the two links below.

As for BB only spooling a little quicker, your example actually makes a pretty strong argument for BB.
7.35psi more boost at 3000 RPM is a significant difference. The initial response of the BB turbo is obviously better. If we had a chart of boost over the whole range, then we could probably extrapolate more data. i.e. the point at which the 2 turbos overcome inertia. A similar comparison of larger turbos would be interesting.
Also, is the BB turbo you reference a dual ball bearing?
Jon,
The GT35R comes in two flavors:
Compressor:
- Wheel Dia - 82mm
- Trim - 56
- A/R - 0.70
Turbine:
-Wheel Dia – 68mm
- Trim – 84
- A/R – 1.06 or 0.82
The only difference being the A/R for the Turbine side. 1.06 or 0.82.
The HKS 3037 comes in several sizes that are smaller or in between the Garrett sizes.
The GT30R is more closely sized to the 3037. See the link Mak posted for more info on the HKS sizes.
All the manufacturers make suitable turbos for most applications. It often just comes down to preference in kit manufacturer, price and availability.

His car is very impressive, but he has a long list of mods to support that turbo. He actually gets his front wheels off the ground when he launches that car, I've seen it personally. He actually has a GT42 now and a 2.4L motor and looking for 800rwhp on his MR2 
I had that same turbo kit on my MR2(GT35R) with almost the same supporting mods, actually got it from him and was hoping to break into 9's in my MR2 but after a few motor rebuilds I gave up
Heres a few pix of my setup
And last my little sleeper
