Expensive....but very nice.

[DaveJ]

Yes, I have the 5 speed version with overdrive 5th. Very nice, very expensive and very noisy, being straight cut, and dog engagement.

The good side is you can go up the box without using the clutch. Full throttle gear changes are possible if your engine management has a suitable input. You can attach it to an Opel CIH engine, using a 4sp alloy bell housing and a 1" thick spacer plate between gearbox and bell housing.

You have a sequential gearbox in your Opel? Was it hard to install?

Here you go, direct from Dave's own webpage:

Hi Dave,


It's very nice !
My problem is:
I want to keep the gear stick in the original position.
the distance between the motor and the stick is +- 515 mm.
If the command is hydraulic, you can put the stick where you want.
But is it like this????

[DaveJ]

No, it isn't hydraulic.

But you can get the gearbox with the stick located in 2 or 3 different places. You can also buy the gearbox with a short or long input shaft.

Where did you get the adapter plate?

i picked up a T-9 a some years back out of a Merkur XR4Ti and i was promised a trace of an adapter plate that came out of England but that was like 4 or 5 years ago

i had be thinking of using the T-9 case and just getting the Quaife gear set for it

thanks

It came out of an old Manta B rally car, fitted with a Ford T9 gearbox, behind a 2.0L CIH engine.

It must have been machined up by someone, but I don't know who.

It is the only one I have ever seen, but then I've never seen another Opel with a T9 gearbox fitted, except mine.

Apart from the plate, a small amount of welding is needed on the alloy 4 speed bell housing, so that decent sized holes can be drilled and tapped for the fixing bolts.

It should be pretty easy to copy from the pics on my web site, if the fabricator has a T9, a 4 speed bell housing, and an old CIH block to work with.

The machining part is just so the plate misses the housing for the front bearing on the T9 input shaft.
