Needing to do a gearbox change on my early 1600 Mk1 plan to fit a Mk2 1.6/1.8 box (stronger internals same as Challenge cars now using) but !, the Mk2 box has a drive for an electronic speedo, obviously not compatible with my wire driven Mk1 speedo, has anybody carried out the conversion & how did you get round the problem, thanks in anticipation (the next question will be has anybody got a good Mk2 gearbox lying around to convert into pound notes ?) I know Autolink etc have them but if I go to Andrew I will end up with a 6 speeder, oh joy !, B Rgds, Paul H, Bicester.
Curborough test day just before getting very close to the 1600 record, even more joy !
1999 1600 MX5 Racing Green (18J) currently standard apart from K & N induction system, Mk1 seats, TR Lane cage, Honda Civic wheels & a few internal refinements for comfort. Apexi big throttle body & six speed gearbox waiting in the garage for next years blitz to start hillclimbing again.
