Default MK3 xr3i gearbox interchangability

Hello all

I have a mk3 xr3i, 1983 model which I have been fettling for the past year. I have got all the body work structurally sorted, and will probably get it sprayed later this year.

Just one thing I need to sort it now is the gearbox which is noisy on the overrun. I have been looking at a cts box but at £600 they are a bit much for a bog standard engine on a car covering less than 2000 miles a year.

Mk3 boxes are getting hard to come by, and I fancy dropping the final drive slightly to get more relaxed motorway speed driving.


I have been looking at mk5 boxes as they have the same mounting but am not sure which models would fit ...from zetec engined models, starter position and all that.

Any advice on what to look for would be very appreciated.

MK5 ESCORT BOXES DO FIT STRAIGHT IN...... YOU NEED THE EARLY ZETEC VDERSIONS THOUGH(STARTER MOTOR AT THE FRONT!!!) IF YOU ARE AFTER THE LONGEST GEARING POSSIBLE,YOU NEED TO GET A GEARBOX OUT OF A MK5 DIESEL MOTOR.JUST REMEMBER TO FIT YOU MK3 GEARBOX MOUNTS TO THE MK5 CASING!!!!!!!!!!!!!

OH I FORGOT, IF YOUR MOTOR IS A 4 SPEED, YOU NEED THE SELECTOR OUT OF A 5 SPEED MK3 OR 4

i think mk5 1.6lx's can do 60 in second gear. which is handy. and all the diffs and stuff for RST's fit in em too.

thanks chaps

so something like a j/k/l escort, even with a zetec engine will fit the bill?

Thanks
