alright fella im in the same boat as you fella i was thinking of dropping in a rs 1800 engine as it wont be as good on juice but it will shock a few people
in my situation i had sold my series 2 as i do go karting so i really needed a bigger van also i was doing about £40 to £50 in juice a week but if i put the rs 1800 lump in then ill only be doing about £30 a week ,were on the diesal i do loads of miles on £10 i wa thinking about putting a slighter closer ratio g/b in to help it out as the gearing is so long
