I have a 96 4Runner with the 3.4L and I just ordered the TRD S/C. I read somewhere that the n/a supra (93+) is a direct plug and play with no other electronic issues. Is this true? If so, is an afc or other fuel control device absolutely necessary for noraml driving? I also plan on finding a smaller pulley which would affect the fuel as well. Who makes them?


Any info is greatly appreciated. Thanks in advance!

No other fuel mods are ABSOLUTLY necessary for normal driving. Many people run the S/C (like myself) w/o any additional fuel mods and have no trouble at all. If you want more performance, which is what i am gathering from your desire to run a smaller pulley, then yes you should probably add fuel mods. Which ones to add and in which order to add them? Sorry i cant help there.

Get 300cc+ injectors and a more powerful fuel pump. That'll keep it from going lean. Do some Dyno runs though, to make sure it isn't lean and isn't rich. Lean will overhead the exhaust manifold.

Eventually, get intake and exhaust headers. And you might want to look into an ECU piggyback or a new ECU all-together.

You WILL need a piggyback to control the bigger injectors. Otherwise you run the risk of washing down the cylinders from running too rich.

..and, it may won't start at all.
