This kit will fit your needs sir, but you will need to upgrade a few things on the car. For example injectors, fuel pump, E85 sensor, FMIC etc.. Also, you will need to think about stock ECU w/piggy back and fuel cut mod or standalone.Long time member on here - I finally picked up a 6spd turbo supra from 2jzmotorsports in utah early this year.
It's completely stock except an HKS ti exhaust and megan racing downpipe 2jzmotorsports installed before I took delivery.
Strongly interested in your long running STU turbo upgrade. I'm located here in Washington State - plan on having Ishii Motorsports do the deed if I move forward.
Powerwise - I would be happy anywhere from 450whp - 500whp. What's most important to me is keeping the stock like driveability - hence I'm not interested in large singles or extensive mods.
Would the STU turbo v4 be the best fit for what I'm looking for? I think so - but wanting to confirm.
I don't have a FMIC - still on stock SMIC - which I think should be adequate for what I want in my power goals? It sounds like above 500 whp would require FMIC, injectors, ECU mods.
