Thank you Magnus for the link, from what I read on the web the 2.6 XR4ti T9 have a different shaft that doesn't work on the 1600 Xflow but will make more research. The price is really good otherwise, hope it fits.

What about the different imput shaft lengths?

Most kit cars are designed for either the short input (4 cyl) or long (6 cyl) European T9 transmissions. The T9 transmissions most commonly found here in the USA are the Merkur XR4Ti type, which have a unique input shaft length midway between the European 4 & 6 versions. Scorpios bound for our shores, 99% of the time, came with automatic transmissions. Using a XR4Ti T9 can pose problems due to this odd input length. It often pays to purchase the right transmission from the kit manufacturer or recommended installation kit for your car

The T9 from a Merkur will not fit in most Caterhams. You need the longer input shaft used on the Sierra.

Hello Doug,

Just what I thought, big difference in size. So, well now I know I have to find one from a sierra, still wonder if I need a short input or a long input, from what I understand caterham or kit car in general use the long shaft transmission so for my 1600 xflow this is what I should look for, I wonder how I can be sure without removing the whole tranny to measure it.

Best to all of you,

I would check blatchat for more information.

Call or email Caterham, they are usually very helpful.

What transmission do you have now?

Yes I will email caterham and see what they come up with.

Thank you Doug

I have a 4 speed transmission right now and on the freeway a 5 speed is a must have.

I was wondering if a Volvo P 1800 E tranny and rear axle would work on the cat because the electronic overdrive was really a blessing and built like a tank, I had 5 coupe P 1800 over the years and loved the 4 speed + overdrive very much.

Maybe we can find an after market overdrive to put on the 4 speed used on the caterham but I think I am stretching it.

Best,

I don't think there is enough room in the transmission tunnel for the Volvo transmission with OD. plus everything else you would need to make it fit make it not worth the effort.

Check with Steve at SPC http://www.spcomponents.co.uk/

Usually better to call as some of these guys don't do email well.

I have often considered swapping in a T-9 into my '62 for the same reasons raised in this thread. So much so, that I have a T-9 on the shelf in my shop. But I haven't gone forward for a number of reasons. I will attempt to highlight the primary issues, below.

But first, for basis of comparison, does anyone here know what is the correct T-9 input shaft length, so that one can validate it with a tape measure, face of transmission to tip of input shaft?

Also, besides input shaft length, there are a few other factors that need to be considered to make the trans swap work out in the end. does anyone here know the answers to any of these issues:
1) Transmission to bellhousing bolt pattern.
The bolt pattern on the T-9 is not the same as that on the old Anglia/Cortina/Escort gearboxes. I'm not sure of the transmission designation, but some of the later Escort 4-speed transmissions have a bolt pattern that is common to the T-9. But not the Cortina and Anglia boxes. IIRC Caterhams with the T-9 use an aluminum adapter plate to match up the bolt patterns and to accomodate the correct input shaft length.
2) Input shaft pilot diameter and number of splines. These both may or may not be different than the older Anglia/Cortina units. If different, this could result in the need for a different pilot bushing in the cranksaft and also possibly a different clutch plate to fit up the T-9.
3) Clutch actuation and starter motor location. Obviously there is a bellhousing configuration out there that somehow mates a T-9 to a Kent engine. However the starter needs to mate to the flywheel gear teeth and you will need to be able to actuate the clutch. Many of the Caterhams that I have seen with the T-9 have a cable operated clutch. This would require some additional attention to adapt or convert to hydraulic.
4) Driveshaft Yoke. The output shaft of the T-9 has a different spline config than the Anglia / Cortina box. So besides the T-9 transmission you may need a new driveshaft yoke and then modify your driveshaft accordingly.
5) Shifter placement. This may require fabrication of a new trans tunnel cover to make the final installation complete, after any transmission mount issues are finalized.

Quantum Mechanics in Oxford CT repairs and sells T-9s. I purchased a seal/gasket kit from them, and I know other Seven owners who have had their T-9 refurbished by them. You'll want to speak with John Esposito.

You are really the best all of you gathering info and thank you very much, after reading some of the post it seems to me it is not worth it to go through all the trouble just to get a 500 rpm lower on 5 gear, I was expecting a 1000 rpm gain.
So it would make sense to wait and get a 1700 cross flow with the T9 attached to it and swap the whole thing. I missed one set for $3500 on ebay last year so we can find some around.

Thank you anyway to all of you.

Ron,

thank you very much for your thorough break down of all the things to do. very instructive indeed.
Did you have time to look at the pix from your seats in my lotus? matching colours hard to beat.
