a friend wants to supercharge his supra

[Supra2NR]

calm down bro,

were us discussing it, jus questions and suggestions
no harm done to anybody..... yet lol

but i was reading about this and supercharger does have its perks
one important thing is the emisions, cuz they spill out less toxic air than a turbo
they're easier to turn street legal

im thinking of getting a jdm 1jzgtte or if im lucky a jdm 2jz but the problem is those engine has twins and none of the emissions goodies, so im looking at running with 3-4 cat converters so i can make my car street legal

but you produce more horses with a turbo, if tuned right

so i cant really tell which one is better cuz i dunt have either and i am going to get a turbo so i am in favor of the turbo

and unless i get both of them in my car and do a lab-reseach on them i really cant tell which one is better
