Timing belt advice please
 

My bug is overdue a timing belt, just wondering if there is any benefit in buying a Cosworth timing belt?

And also is it good practice to replace the water pump too, or have been told a load of cobblers?

Is there anything else that needs could do with being replaced while the belt is being done?

Water Pump, Tensioner and Idler Pulleys - Gates Kevlar (they make Cosworth anyway) Belt and you could uprate the belt guide for a CNC one (Roger Clark, CDF, Cosworth etc.)

just about to do this myself for the first time...
So whats the advantage of the Gates Kevlar belt at well over a hundred quid compared to a normal Gates belt at 60 quid and why change the guide?
:wonder:

a normal gates belt will do fine,unless your running a lot of power through it.your standered guide will be fine too.

Std guides can deflect enough to allow the belt to jump a tooth or two the CNC ones don't.

The Kevlar belts are stronger than std and do not have as much give in them especially if running high power/rpm.

Std car = std parts, uprated car = uprated parts!

Well worth doing the tensioner, water pump and idlers while it's all off though.
