hi all,
can anyone tell what the difference between the two, and how it would affect the build

cheers

mark

Not sure about the physical differences but the MT75 is a much stronger box - good for around 400 bhp iirc.

cheers razman,
so it dont affect the build in any way then

Oh yes it will

The box is slightly bigger.

What engine are you using ?
The Mt75 will handle more grunt.

To get mine in a bookish chassis I moved and changed a few bits.

If you're building to the Champion book then the MT75 might not fit, it's wider so you'll need to lose some room in the footwells.

It's stronger.

Has a integral bellhousing.

It's aluminium cased (lighter ?)

I'm not sure (someone who knows will correct me) but I think the box needs a different type of prop too, the box doesn't have a sliding input like the type9.

well the car im looking at is a 1991 2L twin cam but dont know what box its got on it

MT75

so thats good then?

I've got an MT75. The only real down side is that you will be stuck with the ratios it comes with, not a problem for my set up, but if you wanted to change to a close ratio or higher first gear ratio then you will need a type 9 and a few hundred £.
