1984 mitshubushi lancer turbo engine

Hi, I'm just after a bit of info about the 1984 lancer turbo engine. Ive just been offered the complete package engine, box, loom, etc for £250 and was thinking of fitting it into my chevette project. All i want to know is what mods can be done to the engine ie 16v head from later model without breaking the bank balance. Many thanks
