Hello all,

I have a bugeye impreza with a reasonable amount of mods on it with regards to the handling and braking. I'd like to change the gearbox and diff to a shorter ratio one for increased acceleration at the expense of top end.

Am I correct in thinking that a my01 bugeye has a final drive of 3.54? Or something very close to that.

Would I be right in thinking if I changed the gearbox to a p1 gearbox which is also a ty54 gearbox but with a final drive of 4.44 I would achieve better acceleration?

Any thoughts or hurdles I've missed please post!

Thanks

It would give faster acceleration (I'm not sure the P1 is 4.444 though)
However you will need the correct rear diff with the gearbox as well.

P1 is 4.44 (front and rear) with a 1:1 transfer box, as is the STiv etc (same box)

Ok,. thanks for the confirmation.
Either way you'll need a 4.444 diff then as well, as the bugeye uses a different ratio.
