Ahhh just saw the 14psi bit, so it fits i guess.

Keep the standard rad, get a grs front mount intercooler, give it a really good service, take it to a tuners and get them to set it up. You will see a very useful 170-180 brake on a standard healthy turbo, providing you have a cam with lobes still attached and good compression (check both of these when you service it).

Good luck and have some fun
