I think u r starting off on the wrong foot using an a14, its a fair bit thirstier than an a10, but if u are using a 1200 body the a10 might not be viable powerwise?. Tho i think a stripped out B210 would come close in weight to a B10.
id look at a free flowing exhaust, and least restrictive air intake with cold air induction. the high comp is good,
programmable efi will allow better dyno tuning and lean running on closed loop, an improvement of say 12:1 up to 14:1 air/fuel ratio in highway cruising, thats if u want to spend that amount of time and $. Its possible a tiny main jet coud achieve the same if u can experiment with an a/f meter.
friction modify the motor with slick50 or nulon, likewise the gearbox and diff.
run 50psi in pizza cutter tyres,
also if u r really keen, make up an aerodynamicr front nose out of say perspex, fibreglass of even carbonfiber, and reduce drag underneath with a flat peice under engine bay going as far back and as tidy in meeting up to all edges as possible.
look forward to the results of this project.
