new to supras and cars per se
 

anyways i found my first car a 1990 supra and ive been learning more and more about cars, supras mainly. but do mkiii's come stock with intercooler?

If its turbo they do.

Well thats good news. is a swap really needed then from stock to aftermarket?

if youre going to mod the car to get big power then yes as the stock one wont keep up not to sure what the limits are for a stock int but im sure someone on here can tell you

I have read that the stock intercooler is pretty capable.. I don't think you would have to upgrade it untill 350+ hp..

Again this is just what I have read and I don't have any actual experience with it.

good to know. Whats a good turbo to upgrade with, that wont need anything else to be changed a t3?
