has anyone swapped a 6 speed in to a gb270. Already broken my gearbox once and now looking for a bit more power so will need to do something with the box. Any ideas or suggestions???

thanks

oh currently running about 330ish bhp

 

Providing you use a UK 6 speed box fitting will be a doddle.

No need to mess about with rear diffs. Just a straight forward swap of box and prop shaft.

Even the 5 speed clutch and flywheel will fit.

 

really!!!! if its that easy it'll be coming out real soon

 

It's a doddle. Worse case senario will be the axle stubs at the front of the box in which case you can buy them from subaru then it really is a straight swap.

 

Be carefull to check what rear diff is in your car.


IIRC it is not the same as a 6 speed jobbie, as the later hawkeye 2.5 WRX based cars use a 4.111 diff.

You would be best off getting a later 6 speed out of a 2004 onwards STi, which will allow you to use your front driveshafts, and then get a R160 UK rear diff out of a pre 2006 UK WRX car.

That should make for the easiest swap.
