Now the question is should I stick with the same box or is there another one I could slot in

Quick question... According to the chart, I assume we use the JDM figures..? Just need info on a box for an MY01 WRX. If it helps the number on it is TY754VN2AA. I assume it's a 4.44 ratio but you know what they say about assumptions...

Cheers guys

OK maybe not... I see thats its US and a 3.9... My bad :P

Yep the 01 wrx bugeye is 3.9 final drive.

Seemed an appropriate thread - could anyone advise the gearbox and diff ratios on the AUDM MY07-MY09 GT-Spec B / Sti gearboxes?

Thanks.

i did some searching on here and being reading two different threads on this trans code (TY754VN1AA). just want to know what ratio this box is, cause some threads are saying its 3.9 and others say 4.44. anyone know

help would be appreciated

From my mega super awesome google charts its a 3.9 with 1.1 drop gears (3.54 rear diff).

I'd be double checking with a guru like Doug @ STechnic first.
