turboing n/a supra risks?!

[Tommy88]

This is my girlfriends cousins name who has a 89 supra n/a and wants to turbo it
(i know nothing about toyota i am a subaru guy)

So in his case would it be better to turbo or to swap...better=to easier cheaper

In my subaru 2.5 rs if i were to turbo we could only run 7 psi 10 psi would be pushing the limits now i know that this is a v6 so maybe it could take more boost and be a stronger engine but i am not sure... this summer he will be bringing it down and me and him will be taking on some tough tasks to his car... he will have 4 to 5 thousand dollars to spend.. would it just be better to do basic mods exhuast intake pullies groundingmods or is it worth the hassle of turboing...

thank you for all that can help
