My gearbox has failed on my 94 STI. Can anyone help me source a replacement. Will a UK spec gearbox fit and take the 300 + BHP of my car.

Thanks for any help anyone can give.

CAB,
I don't know how much you were proposing on spending on a replacement box, but I know where you can get hold of a Prodrive SII gearbox for £1300+Vat. That should stand up quite comfortably to 300BHP. If you're interested I'll give you further details.

You may want to try Scubidu in Carlisle who break Impreza's - alternatively another company advertises in Motoring News about breaking Subaru's

It is unlikely that a geabox is broken in a write off. You probably can find a WRX/STi box in one of those places.
