For competitive road racing/time attack on E85 and/or built motor, twinscroll 7163 is the call and for very high output the 7670 or 8374 make sense. As a rule of thumb - twinscroll spools faster and makes more midrange torque, but slightly less top end than singlescroll
-For a street/strip/highway build, singlescroll 6758 and 7163 are the call. Singlescroll spools little later (less torque) but makes more top end HP. As a result of the softer torque curve, singlescroll is usually more foregiving on the drivetrain. If you build your motor in the future it will allow for the optional 0.85 a/r with a built motor (whereas twinscroll is 0.80 a/r)

Thanks
I think to me single scroll be better.
do 7163 keep power over 7400rpm?
I really happy to see Full-race brz kit and i hope you tune it on dyno with record setting result .
I like your first ecu tune be on 9psi. I like 9psi because it is exactly double power (250-260TQ) and 9psi is safe for stock engine.
Do you tune with ecutek or you plan to tune with other ecu tuning like motec M1 or Haltech?
it seems ecutek has less than full control over DI.
In my idea all thing in this kit (between all other turbo kits) seems to be perfect to me but the only thing i like to be better is FMIC look.
Crawford FMIC is alittle more beautiful.
Do you give customer option for crawford FMIC?
