Does anyone have any experiance with the HKS ball bearing turbos. specifically the HKS turbine GT3037S 56t. what is approximate HP at 15psi with this type of turbo on a streetported 13b. All I know is that the spoolup time is minimal and "the power potential" is excellent (from what I'm told), which is pretty self evident.

I would love to know the Garret equivalent or if it will make a promising future rotary project :P..... Any opinions?

kinda small for a single! run twins~

The smallest GT series that can be run as a single is the GT3040 and you have the run the largest ex housing in order to make good power. Like Soul Assasin said.. use twins for GT3037 or smaller.

GT3240 or 3540 provide the best single turbo matching.

Use the twins, but it'll cost ya big $$$

Some of the Supra guys have talked about stepping up from the twin 2835s to the twin 3037s, which should be interesting since they have been making around a 1000 at the crank with the 2835s.
