Hey guys.

I designed a set of turbochargers for the Supra TT for sequential and non sequential operations. It is almost identicle to the RX7 stage 3's. I did lots of machine work to make it happen. The stock supra turbochargers have really weak shafts and no one has come out with anything for them. I have sold a few sets to Speedforsale and they are the only ones pushing the product. It is expensive but there is 450 dollars worth of AN fittings to make them work on the car. The oil feed and drain is located on the bottom of the turbochargers, so custom lines and fitment is needed for the coolant and oil lines. Other than that, you put the heat shield around the turbochargers and they look stock! BTW I had a customer about a year or 2 ago dyno my first set and it made 597 RWHP at 28 psi of boost.

Bryan,

What would be the possibility of making/modifying a Manifold to work better with your FD BNR's in sequential mode??? I, for one, would either purchase them new and/or send in a manifold for core in a heart beat.

I wouldnt bother with doing a custom exhaust manifold. There isn't much you can do with the stock exhaust manifold. The turbine housings will only flow 425 RWHP worth of air flow.

Out of curiousity, 425rwhp measured on what kind of Dyno?

I know Rich did 421 back in the day at 17.5psi.. I'm currently pushing 325rwhp at 16psi on a dyno-dynamics brand dyno. The difference in number between Dyno-Dynamics and something like Dyno-Jet ends up being like 15-18%..

Should I expect to see my top end power in 100rwhp, or closer to 40 (add 18% and I'd be making 383 "American" rwhp)???

I don't know much about the differences between the dyno calculations. I just recently built a rew with non sequential stage 3's. It made 370 at 14.5 psi. The car trapped 120.X mph in the 1/4. The math works out pretty even when entering the numbers in a 1/4 calculator. Maybe you ought to go to the drag strip and run it to see the mph, then you will know how far off the dyno is...
