No front coupe brakes wont fit because coupes and hgt,s have a different hub carrier. the rear disks will fit and will look good but you wont notice any improvement.
Why change oil pump?
I've had 2 rear disc conversions done now (naturally on different cars) and have to say performance wasn't really affected on the first car (Brava) but the Bravo was quite noticeably better but that was down to worn out drums and shoes.
You'd be better off investing in a decent disc and pad set.
