how hard is it to fit a mgb overdrive box into a b series marina

[wfb]

You will probably need the mgb's engine back plate and flywheel and there is a bit of cutting to do on the marina's tunnel. Try asking on the marina forum or have a look at this link. www.dep-o.co.uk/features/morris-marina-pt1/

Quite. The Marina uses a very similar gearbox to a Dolomite/ Spitfire, which is very small. The transmission tunnel is integral to the floor and tiny, so options are very limited.

The Spitfire overdrive 'box is a closer fit but still requires cutting the tunnel, as well as changing the input shaft on the gearbox and shortening the prop.

It's probably easier to start with a Dolomite in the first place!

thanks for the info
ill keep it as it is then i just sold both my dolomites as i wanned something diffrent lol

What about a Rover LT77 five-speed box, could that be persuaded to fit?

I have a ford type nine 5speed gearbox on the Marina 1275 engine in my Morris Minor so I guess the same box could be fitted into the Marina?

It's still a reasonably involved conversion (bellhousing, gearbox crossmember & propshaft mods as I recall), but type 9 does fit in the transmission tunnel- although the gearstick is in the wrong place, so you still need to do a bit of cutting.

The Triumph Spitfire 1500 and 1500/1850 Dolomites use essentially the same gearbox as the Marina.

I did fit a 1500 Spit O/D gearbox into my Marina Coupe and had to raise the transmission tunnel by 50mm as on the overdrive version, the gear selector shaft runs over the top of the overdrive unit and into a housing mounted on the top of the main gearbox casing.

I have switched over to a Type9 Ford, it will fit without cutting the tunnel other than the gearstick comes up about 100mm further back.

There's a guy on EBay selling modified Type9 boxes with the gearstick remounted 100mm forward, so perfect for Marina, Dolly or Spitfire.

If funds allow, that's got to be the best option I'd have thought.
