dont want to stick another 2nd hand one in it, so was wondering if anyone else has upgraded theirs and if so with what?
Can you tell us what is happening to the box? Is it a stripped gear, or is it worn synchro's (crunchy gear changes)?
IIRC John Bradshaw ran a stock box for quite some drag events without managing to break it. His car was running well over 600bhp, and used drag slicks/ prepped track, so I too would be surprised if road tyres/tarmac would give enough grip to damage the gears.
