Overall Impression:
This Supra is one of the coolest sounding “street” cars I have been around. It idles like a cam’d up big block V8 at idle, but has that sweet distinctive 2JZ sound while running. This set-up made very good power considering it’s still fairly basic. Custom intake manifold, larger throttle body, larger intercooler and charge pipes and race gas tune are in the future. Should be able to see around 1000-1100whp at 40-45 psi! This is a solid high 8 second 1/4 mile car when completed down the road, but will still be able to drive on the street.

Overall Impression:
Dotted red lines are baseline pull at 18 psi with a street tune done by the previous owner. Solid red lines are custom Evans Tuning tune with 20 psi of boost. Huge gains!

Overall Impression:
This engine desperately needs cams! There is easy 150 whp+ in larger cams! Boost was kept off of wastegate just to get a basic tune done before building the engine.
Large dip in graph was the auto transmission upshifting during the pull. Was nearly impossible to make a pull without the transmission upshifting during the run. For a 100% stock transmission/converter this is making about as much power as it can take, and in fact run to run it was not consistent due to slippage from the converter. Also, could not get more boost out of the wastegate due to low psi spring.
Anything more than 13-14psi we experienced bad ignition misfire. Needs a HKS DLI, or other ignition amplifier. Power was decent for stock cams, but 272′s would pick up a ton of power.
