Is it easy? what are the basic steps to fitting, what has to come off?

water pump , balancer , timing cover , fuel pump , timing chain

i couldnt use std fuel pump on mine but im told i shopuld have been able too , i used twin electric pumps

put on gears - should be instructions , you have to check endfloat and time it properly
put show back together

easy - i wouldnt use a jp gear set though , there got too much clearance in them and i had heaps of wear in only a few thousand kays , i went back to chain

another tricky thing is timing cover as it is usually put oin before sump , and can be a pain
