im looking for info for my build i would like to know what would be the best diff 7" or 7.5" and what would be the best ratio and which gearbox mt75 or type 9 5 speed or 4 speed thanks

A good starting place is probably what engine you would like - Do you have any preference? Car engine or bike engine?

Are you going to be using a donor car, or collecting part individually? Will the build be sierra or mx5 based?

well im going down the sierra route but hoping to put a 2 litre zetec in it as im only just starting i need a lot of tips and help i suppose

This site will certainly help with regards to fitting a Zetec, http://toyne.org.uk/zetec-engine.html

I would go with the type 9 box as gives you more room for your feet,


Good luck with your build and have fun.

The book chassis is meant for the 7" diff, but if you had a 7.5" one, you could easily make the diff mounting plates a bit wider to accomodate that.
