Correct me if I'm wrong anybody, but from my understanding on 4runners its less expensive to supercharge it and you get more out of it. In fact i don't even think you can buy a turbocharger for a runner.
Yeah, somebody may make a turbo out there for our engines, but the TRD supercharger is the best option we have for extra power. Anything else I would be wary of. BTW 4runwinchicago, are you sure you're running 285/75/16s on a non-lifted 4runner?
