maybe you would never put a SC on a 4 banger but that doesnt mean others shouldnt. you can go the turbo route if you want. but you're going to be the one who deals with heat, fitment, overboosting, spool, boost leaks, or whatever problems that are commonly associated with turbos...
PS: centrifugal SC are crap imo, only rotrex is worthy as a consideration.

Is the Tundra a 4 banger? Like I said, of all the S/C'ers for Imports (mostly 4 bangers), I have yet to see one out perform a properly configured turbo setup on the same car.
Turbo's, especially Dual BB have minimal lag when a competent tuner specs out the engine and setup. Key word here is "Competent". You run a bigger A/R on the turbine, it will effectively move your peak torqe and change up your power band. Tuning the car via the dyno with a tuner who knows what he is doing, can deliver a flat torque curve for you. Like I said though, the turbo has to be Matched to what you are trying to do. Peaky torque curves are fun for the street. Flat broad ones are ideal for the track.
S/C is not more efficient than a properly matched turbine. Not in the Import 4banger world. Proper Wastegate size = No overboosting. Heat is a byproduct of both S/C and turbos, no difference there. Either can suffer from boost leaks...it's called a vaccum leak.
