I wouldn't really think there is a need to run water injection in the UK, I would use BP Ultimate fuel, which is 99ron I think. I wonder why the 4e-fe was not labelled a 4e-fhe by toyota, as far as I am aware the 'h' stands for high compression.
Cheers man, finally going good!
Not much of an update, but I have finally clocked 1000 miles since the rebuild.
