diff ratio??

[400watson]

Could somebody please tell me what the correct diff ratio is for a mk1 mexico 1600 x-flow! Also the best ratio to suit fast road?? thankyou for your help, Mark.

I think they were 3.77:1

 

Fast road ratio all depends on whether you'll be running a 4 or 5 speed box.

 

My escort runs a 3.9:1 diff with a 5 speed...

 

If you're gonna keep yours 4 speed then I'd keep the same diff ratio

 

But that's just me

3.77 diff in a mexico...3.54 Rs 2000....,.Both slightly higher for top end and motorway stuff..3.89 and 4.1 for traffic light racing
