Petes MK1 Race Car - Can he fit a 6 speed Mk2 Gearbox?

Pete is a real MX5/Roadster enthusiast and as such owns all version of the car. He's also incredibly unlucky with his cars which suffer from just about every ailment we have come across (and a few we haven't - yet). With your help we can keep all his cars on the road and the smile on his face so please come in and see if you can help.

THESE ARE COMMON AND GENUINE PROBLEMS WITH REAL ANSWERS - WELL WORTH A READ

Petes MK1 Race Car - Can he fit a 6 speed Mk2 Gearbox?

Postby MrChrome » Sat Oct 27, 2012 8:10 pm

Pete's latest idea is to fit a MK2/Mk2.5 6 Speed Gearbox in his MK1 race car.

Will it fit?

Yes, it will fit.

However to carry out a complete conversion he will need the plate between the engine & box from the 6-speed as there is a slight difference to one of the bolt holes for the starter.

Also ideally he'd use the MK2 starter as the MKI starter will only mount using 2 of the 3 bolts. The MK2 starter is lighter than the MK1 version which is useful in a race car.

The mechanical speedo drive needs to be moved from his old gearbox as the 6-speed has an electronic drive (easy job - 1 x bolt).

The connectors to one of the switches (neutral or reverse, I can't remember off hand) need to be changed to a different type, again an easy job.

And before he does anything he needs to check the race series regs to make sure a 6 speed box is allowed.
