Hi, i currently own a LH Torana (173), and want more power. The engine is currently stock with a 2" sports exhaust. I was either thinking of doing up the 173 red motor or buying a v8. Im not all that keen on having to change the gearbox, diff ect, if i put a v8 in though. I was looking to spend $2000- $3000 with doing most of the work myself.
Has anyone done up a 173? What sort of power do they produce? Is it just a waste of time?
