My focus 2.0l mk1 petrol grinds into 2ND and 3RD. lookin to replace the box. is an st box an easy mod? or a diesel box?
or does anybody else have any ideas of a decent mod to do?
thanks ppl

 

focus 1.8 Ib5

less trans loss (ib5 avrages 15% where the mtx75 is 17%) and you get shorter ratios so better 0-60 but lower top speed (ib5 still good for 135+) and you can fit the 1.8 flywheel at the same time which is lighter so you get a free reving engine.

but its not a good box for high power (ie 250bhp+) but good for lower power cars

you would need
pair of drive shafts
gearbox
flywheel
gear cables
gear selector (gear stick)
and the rev switch plug from an ib5 (im pritty sure thay differ to mtx75)

 

thanks great info. only running at 131bhp.

 

Standard then, thing I would ask myself though is why did Ford fit the MTX, if they could get away with fitting the IB5, like they did on all other petrol models (Barring hot models) there must be good reason?

If those ratios are short I dread to think what the MTX is like, I have always found the IB5 to be tall gearing.

Because ford use what ever box thay have to hand, like in the mondeo and fiesta st both same engine but fiesta uses ib5 mondeo mtx75.

First is alittle bit taller but every other gear is shorter than a mtx75.

 

its an awquard job changing the box, had it out once to do the clutch ( not keen on doing it again) but its getting realy bad now. i think ill stay standard to save the hastle. thanks for all your advice folks!
