Might sound a silly question but here goes..........
Will any parts from a sport gearbox ie centre diff and rear casing fit onto my turbo gearbox??
A friend has a sport gearbox from the same year as mine but has a 5th gear fault where mines has a fault on the output shaft area and this may be a quick fix.........well maybe.....but worth asking

I have a centre diff and casing from an MY98 WRX for sale. Its from a TY752 box and has 1:1 drop gears so you would need to check if yours is the same.

You could try calling David at API for advice.

my car is a 97 uk impreza, will try dadid api later but if anyone knows feel free to leave a comment
