In general, is it an acceptable practice to attach a performance enhancing turbocharger to a stock engine without changing anything such as pistons, or crankshafts?

Also on a side note, if my main preference was to accelerate quickly and then to stop accelerating at a certain velocity, would it make more sense to search out a turbo charger thats focus is on the low rpm range, or the high rpm range?

I have a 1995 acura, non-v-tec, 1.8 litre b18b engine, it seems to me that the acceleration on my car naturally kicks in at high rpms, but not so much in the low range.

 

we made 312 whp on a stock ls turbo last night. only mod is rod bolts. its all in the tune
