Obviously you will need a engine consisting of all brand new parts, and built correctly. This is the biggest key to fast spool.

Although if you set your power goals lower, a GTX3071R would spool faster, and on a race gas only tune & higher boost maybe make 350rwhp...

There are several variations to the same theme, here is another one that absolutely flies:

--------------------------------------------------

Power: 370 HP and 300 TQ to the Wheels at 16 PSI of Boost

- 13Brew (2 rotor turbo out of a 3rd gen RX-7)
- 9.7 high compression Super Lightweight rotors
- Racing Beat Street port
- Ceramic Apex seals
- Garrett GTX3076 Turbo
- Tial 52mm wastegate
- Motec boost controller
- Tial BOV
- 7parts Stainless Manifold
- Coast Fab. 3" Race Exhaust
- Motor built by Jim Mederer of Racing Beat
- 7Parts Custom Intercooler
- Racing Beat Aluminum side housings
