Thinking about converting to sierra gearbox for 1098 minor

[ssnjimb]

Hi

Iam thinking about converting my minor to the 4 or 5 speed Sierra gearbox.

There are some earlier type 3 4 speed gearbox's about that are cheap do they have any benefits over the 5 speed type 9

What type of work is required to convert.

what parts are needed. Should i buy a kit and then source the gearbox seperately.

Can't see the point of spending all that money - and all the hassle. Just stick a 3.7 diff in the axle - works well.

If you've got the time and money, it's worth it.
A 3.7 with standard 1098 id fine except on hills where the gap between gears is too big.

Plenty hills in Scotland - it works fine on my car, although the engine has been 'improved' somewhat.

I'd go along with that. The Ford box is a little bit porridge like, compared with an MGB gearbox or the Spitfire overdrive box in my Midget (That's a great box and if I had the time, I'd like to fit one to the Minor). However, the Ford conversion is available, it takes into account the Minor steering rack and it works. The standard Ford box has a tree pulling bottom gear, with quite a gap to second.

I would agree - if it didn't cost the thick-end of £1000 to do the conversion!

I will start saving my money up for the conversion kit first. Jamie

The 5 speed kit does not cost 1000 if you buy a second hand box it comes in at less than 500 and that is using brand new conversion parts.
