I had planned to build a short stroke, blown 1000cc to use in sprint and hill climb series. Classes ran up to 1.4 and over 1.4 with a 1.4x for forced induction. I had planned to use an MED billet 970 crank but in the time it took for me to save for such an £££ item MED stopped selling them
Truth is I don't have the time to commit to a full on race season, and hill climb looked to be a way to have fun and rag my mini when commitments allowed. I do about 5-6 track days a year in my MINI so I guess it would be nice to have the option to use the Mini for circuit racing too.
I'm therefore kicking the idea of a EFI 8 port around instead. My question is, to the racers out there, what sort of usable power can I expect from such an engine? What size piston and stroke would work best? Would it be the sort of engine that needs lots of revs and need a 4 bolt main or would it be a low down torque thing?
I'm thinking of the Minispares 8 port EFI cam, which is a 310 I believe, on an A+ 1275 block with cylinder liners. I already have the ECU, SC gearbox and want a pre-verto clutch. I'll probably get the crank, rods, pistons & clutch from MED or Swiftune and have them balance the whole assembly for me.
Oh and it has to be something fruity!!
