5 Speed Conversion.

Post by **d_harris** » Wed Apr 30, 2008 9:56 am

Okay boys and girls, I've tracked down a suitable 5 speeder type 9

and I'm trying to work out what I am going to need in order to fit it.

Obviously I'm going to need to do something about the bellhousing, I'm guessing the clutch will need to be changed - for what I don't really know. And I seem to recall something about the crossmember too.

Any Ideads for the next step?

Does anyone have an idiots guide?

there are kits available from the major supliers.

I think about £500 is what it costs for the bits. Type 9 feels nice with a quick shift also, but another £50.

mine has a birmingham kit with different release bearing and a sierra 1.6 clutch.

Spotted that,

But I've already got this 'box (well, still have to pick it up....)

I'm looking to fabricate as much as humanly possible to keep costs down

I like the (sic) 'Supacharger'!

Prospective buyers of the Fiat box should be aware the top gear ratio is 1:1. ie - It doesn't have any 'overdive' capability and so gives little advantage over a normal 4 speed box. I suppose in a highly tuned engine with a very narrow 'rev' band - the 5 speeds may be useful - but a normal or mildly modified engine copes fine with the normal 4 speeds.

Just out of interest, has anyone every tried fitting one of the OD boxes from a triumph/MG in a Minor?
Are they massively too big?

There must be a cheaper 'bodgers' way other than throwing loads of money at sierra conversions.

Have you seen the price of an OD Triumph 4 pot OHV box though?

Sierra ones are a lot cheaper (or used to be last time I looked a couple of years ago). It's nice to have a couple more gears at the flick of a switch (till the wires short and electrocute you every time you touch the stick) but they're heavy, quite bulky and pretty complicated.

The plus side is there's no need for a custom bellhousing, but you do need the Marina flywheel and probably back plate.
