Does the V6 manual gearbox mate up to a Vauxhall 2 litre red top engine?

Maybe looking at a kit car project!!

It would go even better with a V6 Engine    (Couldn't resist, sorry  )

Diesel 4pot boxes have a different belhousing... Trouble is all the bell housings are integrated to the casing, which complicates matters somewhat... Think 6pot diesels are a different box altogether

4 pot petrol manuals might be easier to get hold of...

I believe the GM bellhousings were the same between the 4 pot and 6 pot X series engines so yes, I reckon it would fit. Might need to do some digging for a clutch that's the right depth.

Then again, I think the gearbox ratios are pretty poor for a kit car. The Omega manual has a very short 1st gear.

will fit, straight bolt on to red top

Don't Westfield et al do a suitable bell housing conversion for the XE to MT75 or Type 9 Ford boxes

T9 is big, heavy, weak and (now) expensive. The gearshift isn't very good either. About the only thing in its favour is that different gearkits are available.


MT75 is basically Ford's take on the Getrag 'box that Vauxhall used, and doesn't have a separate bellhousing.


I'd use an Omega 'box from a four cylinder car as the ratios are likely to be more suitable than a V6 one. And it's a bolt together using readily available, cheap and standard parts.

The ideal box for a red top is the 1800 manta berlineta gearbok and sump, there was a conversion kit to fit fu*k boxes to the red top. Googly is your friend.

Like a manual Omega then ....... 







(I've only ever driven one manual Omega - a 2.5 diseasal for a couple of miles   )

I agree on all counts but don't underestimate how poor a powerful, lightweight car will be on Omega manual gearbox ratios.

Here are the Omega ratios:

http://www.omegaowners.com/forum/index.php?topic=90453.0

3.95:1 1st gear is a joke, so certainly give the V6 gearbox a wide berth.
3.81:1 on the 4 pots might be bearable but you might well hanker for an upgrade, especially if you tune the engine.

I have an MT75 in mine. First is 3.61:1 and is still pretty much a waste of time. It hits the limiter around 30 MPH. Limiter is at 7500 RPM! 0-30 takes no time at all, assuming you get some traction! You probably spend more time getting 2nd than revving out in 1st. 2nd takes you straight to 60 MPH.

That's with a 3.62 diff ratio and 15" alloys.

I would say go with the T9 despite its' weaknesses. Bellhousings for the GM engines are available, all the standard Westfield bits - propshaft, etc. will work, as it's a well trodden route, and you have an upgrade path when you've had enough of the ratios or when you tune the engine beyond the standard box's capabilities..

If it's just going to be a road car on a budget, I'm sure the Omega gearbox is possible but:

1. Use a 3.6 or taller diff, and be prepared to regard it as a 4 speed box that starts with 2nd.
2. Make sure it'll fit the chassis tunnel. I'd bet that the Omega box is shorter than the T9 but much wider.
3. Make sure you know the cost of adapting propshafts, engine and gearbox mounts, clutch actuation, etc. to suit it. It may be a false economy anyway. 

BTW: Mitchell Cotts now make an MT75 with bolt-on bellhousing, but the cost is eye watering and still no alternative gearkits for sensible money.

Good luck with the project, though.

Thanks for all the comments. Reason I was going to use a V6 manual box was I have one So it is free!

I know the ratios are crap so are MT75 and Type 9 without going to the expense of new gears.

Just trying to use up some of the bits from my old 2.5 Estate.
