Most likely not.

If your ecu measures air via pressure (aka "a MAP sensor") then that ecu probably won't know what to do with positive pressure...since an n/a engine rarely produces that condition.

If your ecu measures air via airflow (aka "MAF"), then it's *possible* your ecu will know what to do with the extra air getting pushed into the engine with the turbo...but only until you run out of fuel. However, you can't *only* upgrade your injectors to ensure you don't run out of fuel, because then your ecu will squirt too much fuel under all conditions. Together with a simple fuel controller (like an A'PEXi S-AFC), this might work.

Oh, I'd be remiss if I failed to mention (as I have in other threads) that slapping a turbo on an n/a Mkiv does NOT result in anything close to the car you'd get if you started with a TT to begin with. Brake rotors, calipers, ABS ecu, engine, ignition, suspension, transmission, differential, etc., etc., etc. are all MUCH, MUCH better in the Mkiv TT. If you really want to end up with a car that has all of the capabilities of the Mkiv TT, you will NOT get anything even remotely close by putting a turbo on an n/a. It's FAR cheaper to sell your n/a and buy a TT, if that's what you really want.

Other members of the forum please feel free to contribute here...I've never owned an n/a Supra, so it's not my area of expertise.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
