auyt Posted September 20, 2020 Share Posted September 20, 2020 I'm considering changing the gear box to the 5 speed however the chassis would need considerable mods, however has any one done this mod or is it worth considering a different gearbox.yes there's are lots to change, I'm not naive to what's involved. Just looking for alternative gearboxes. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted September 20, 2020 Share Posted September 20, 2020 Mk1 MX-5 box is sweet though adaptor plate and prop would need to be custom, location of gear lever may not align either...ratios will not be perfect for a 7, speedo calibration / drive will need looking at as will the location of the rear mount.or Ask Steve at Tracsport to build you a box with proper ratios that will fit, with his Tracsport semi helical gearshttps://www.tracsport.com/gearkitsoptions on 1st and 5th gear ratios.
