So my goal is to be able to make 350-400whp in my 13b miata. I have a HTA3582r but i want something smaller. I have been thinking of doing a BW s256sx turbo. The turbo flows 55lb and come in 1.00a/r, 1.05a/r, and 1.22a/r. I want to road race and time trial the car. I am very new to rotary but i am not new to turbos. My last miata that had a built motor made 350whp on a evo16g 20psi that i tuned myself. I sold that car and bought this car for a few reason. One reason is the rotary revs out higher then a BP motor will as the BP motor has high rpm vibrations that crack, loosen, and shatter stuff on the motor. The next reason is it weight a lot less then the miata motor.

So let me know what you guys think i should do. the motor in the car is stock but i have another motor that i am building with RA super seals and port work.

here is the link to the BW turbo i was talking about.

I can't say anything about the BW turbos, but the T04S, T 60-1, T 62-1, and T04E in 57 or 60 trim are all good choices for that power level with a quick spool.
