88 wagon potential

hello. i'm just wondering if anyone out there has any relevant information for me. i just acquired a 1988 suby wagon with the n/a ea82 carby engine. i am willing to spend around 2500-3000 grand on a conversion. i am a mechanic so labour is not an issue. i would like a turbo enigine maybe a wrx donk but i also want minimal fuss installing the (fabricating parts and such). i live in australia and have access to importer's. if anyone has any information it would be greatly appreciated. cheers
