As per title can I use any classic gearbox in my 94 RA as long as its a 4.111 like the original? I was planning on removing my RA box and saving, then buying an STi box with different ratio's to use in it on track.


Cheers in advance

Thought the RA ran a 4.444?

No The early RA's are 4.111 and the later RA STi is 4.444 as you suggest

I thought early RA boxes were 3.9, don't suppose you'd get rid of the box once removed?

I have a 93 WRX RA. Best swap is TY752VB3FA from 95 STI. Has improved double cone 2nd gear synchro as well. Straight swap 4.1:1 diff.

94 STI RA had 3.9 diffs. very rare ratio in classic only fitted to that model.
WRX RA had the 4.1:1 diffs as fitted to normal WRX.

Your info is not at all correct fella...

The MY93 WRX RA and M94 WRX RA uses a 4.1 FD

The MY95 WRX RA/STI RA and MY96 WRX RA/STI RA uses a 3.9 FD.

Absolutely correct... just refreshed my memory via the tranny chart. Must be old age...
