hello i have a 94 uk impreza turbo and first gear has started knocking so have seen a box model no. ty752vb3ba which i have looked up on another thread and worked out it is a my93 ra box was wandering if this will fit in my car any help appreciated thanks ...

I'm not sure about fitment, although I don't see why it wouldn't.

But bare in mind that the RA box has much shorter gearing than
your current UK box, if you do alot of M/way driving it's not ideal !

A blinding 0-60 and it's stronger.

Not to mention hair trigger response in any gear.

Think:
1
You will need to change the rear diff maybe (check the ratio)
2
The RA came with a 7500 rpm red band (8ooo ?) and with the ratios you will need them Your UK turbo does not come with such a high rev band.
This will mean the gears will 'run-out' even faster than the stock RA.
3
I had a RA box in my competition Sti v3 for 3 months before ripping it out.
Driving it on the road will buzzz your head and fuel costs will rocket, but it sure will accellerate and pick-up in ANY gear!

cheers graham will check the ratio of the diff and will probably give this gearbox a try and rebuild my uk one in my own time and keep car on road and see which i prefer thanks again Rick..

As above.

It will go like **** but be terrible on motorways.

Thrashing the nuts off at 70mph.

wormeo

the motorway limit is 70 i never go faster than that thanks mate

leonpoole

You will definatley need the rear diff. I know because i done the same gearbox change to mine

wormeo

Tomorrow call David at www.apiengines.com
Tell him '911' sent you (he might still talk to you after!)

far easier way is to use your UK crownwheel/pinion in the RA box and bolt your centre diff onto the back...............

have done loads of these types of conversions and far easier job than swapping the rear diff

ok thanks think i will have a look at swaping the bits rather than getting the diff thanks for the help guys
