the 8v is slowly dying, and I've got about 3000 miles to cover during the summer holidays and I'm pretty sure the car wouldn't make it as it is.
Dying?
I thought it was running like a beast, and making nearly as much as an ABF?
It was, but since I had that oil leak it's been running a tad flat.

3000miles! you youring the uk or something? 
cant believe your loosing the 8v though 
Going to the most northwestern part of Spain, then down to Portugal, then over to Madrid, then back to north west Spain, then back to the UK. I'm calculating about 3500 miles or so.

+1 even if this is the case I cannot see the point of fitting an ABF, your going to need a lot of parts plus wiring to sort, a lot of work for very little gain plus harder / more expensive to tune.
Not that hard fitting an ABF, remember that the golf 3 was meant to have the ABF ass standard, so everything is pretty much there.
ABF is far more tunable, at an expense, but worth it.
