Good to see you back but bad news with the gearbox bud

Google your ty ##### number off the white sticker on the bell housing to find out your ratio .

And find out what "R" number your current diff is (either a R160 or R180 ) .

If your lucky enough to find a 6 speed with the same ratio and diff type you'd only need ....

6 sp Gearbox

6sp Cradle /mounts

6 sp Gearknob/linkage

And 6 sp prop .

As the newage 5 speed box's

Clutch , slave,starter,fly, shafts,speed sensor ,front shafts are all compatable with 6 speed box . So if the ratio and diff type are the same you can leave everything original from the prop back and the flywheel forward on the car

If you can't find the right 6 speed you'll need the all above plus it's matching diff ,shafts and rear hubs (possibly brakes and discs as well)

Think that's the last year they used the male driveshafts on the front ,so they're might be other differences .

mine was out of a 04 uk sti with the Prodrive performance package (the Ppp is a bonus as you get a short shift gear linkage)

I've found 1 st and 3rd seem to be shorter than my old UK turbos 5 speed set up but I've dropped about 500 rpm @ 70 mph in 6 th [emoji41]

If it's not broke .....upgrade it 😊
