is a standard gearbox good enought for a 1800 engine?

yep

all i needed to know cheers

Yep, until it breaks......:P

hehehehe

Standard box will be ok, had modified box in my Baja behind a 1835,managed to break that and was going to cost big dollars to fix. Went back to standard at least in future if they break a hell of a lot cheaper and simpler to fix yourself.
