Ben Ive been down this road myself...if you are going to use the truck everyday then yes it makes sense to change the unit however for the odd trip and odd weekend its cheaper to leave well alone as you never get back what youve spent..I spent £4000.00 fitting a Cummins into a Zil 157K and yes it ran well but for all the times I used it..Id have been better spending the 4K on another truck!regards from a very cold North-Northumberland.malcolm
