Well after a long wait, I have the car on the road and its quite a set up. I went with the S372 turbo with the .90ar. I had Jim of JPR Imports in NJ and his awesome fabricator Keith make a manifold for the turbo and a 4inch exhaust. I ended up running two walbros in tank. The car currently is seeing a full 12lbs of boost at 3800-4000rpms in 4th gear with a rough tune and conservative tune and pulls really hard. I have so many pics of everything but dont know how to post pics! I'll have my buddy post them up for me. Thanks to everyone for the help and great direction, im very excited to see what this car is going to put down at 20psi.

Well the 90ar is a hit for me as I was looking to keep the car below 30psi. The car hits 20psi at about 4500rpms and pulls really hard to my redline of 8500rpms. My buddy has a 550whp 240 and my car pulls on him. Its really fun to drive and such an exhilarating ride. Im looking at going with water or meth injections and more boost.

Really interested in know what your 20psi dyno numbers look like bro...
Looks like the S372 worked out well for you, I think with the .90a/r you should have a great power curve to 24-25psi, beyond that you may see some boost drop toward redline... but you can't use over 24PSI (~600rwhp) on the street anyway, 99% of the single turbo's Supras out there won't see you at 24PSI on the street either...trust me.

Is the .90 a fully divided housing? Sounds like that BW s372 is a good spooling turbo for it's size. You're reaching 20 psi prob about 400 rpms sooner then me. Mine isn't ball bearing or anything though. I plan on adding a 4" exhaust and a divided housing to hopefully gain some quicker spool too. Even a couple hundred rpms would be nice.

I took these 2 quick videos from the passenger seat a few days ago. They're definitely not the best, but you can atleast get an idea. He currently has it backed down to 15 psi. I couldn't keep the camera still in the first vid and in the 2nd video, he bogged down in 3rd because he just spun through 1st and 2nd (was a little cold out though).

Im in 4th gear when getting 20psi at 4500rpm. I run 20psi on 93octane and 11.5AFR and 12 degrees of timing. Its pretty conservative as I have not been on the dyno and 4th gear pulls on the highway are hard to tune at 140+mph! haha.
It is a .90 divided housing and 4inch exhaust. The car is very loud! The videos that Brian put up do not serve the car justice and they are at 15psi.

I just dynoed my car the other day and we made 471.4whp (uncorrected)@ 12psi with the Borg Warner s372 with 1.25 A/R and a Cosmo Half Bridge. I will be ruinning 26psi soon, but just going to break in the motor for a bit more with the low boost.... This turbo is Wicked and spools faster then my T88H
