My S3 has a five speed manual fitted which makes a massive difference.
Good luck with the conversion and take more pictures !
Aaaah! Then that makes sense, using a nice leggy fifth gear to use the torque. Are you using the Rover derived box or a Getrag item?Good luck with the conversion and take more pictures !
I'm wondering if you could use the ZF 4HP22 (non swithcable) from the old 7 Series?
One of my two XJ-S's was a V12 manual using the old four speed Massey Fergusson box* and that was a real weapon. 100 mph off any motorway slip road............then into fourth. :-)

To be honest I'm not sure. The previous owner fitted the box and I never thought to ask and I haven't even looked. I have a feeling it's the Rover derived box, but I'll find out.I'm wondering if you could use the ZF 4HP22 (non swithcable) from the old 7 Series?

In an ideal world I'd rather it was a four or five speed automatic but I remember looking into these a few years ago and the cost was prohibitive.
I used to have a V12E with a fuel injected Rob Beere engine (400+ hp) - that was quite impressive and had an American gearbox fitted - excellent bit of kit.
The GM400 auto was the weak link on the V12 - the ratios were never really right and they had a propensity to stop working around 50-60'000. Mine failed at 65'000, was rebuilt, failed again for the next owner and was replaced by a new one from Jaguar - which at £950 (in 1990!) was only twice as much as a crap rebuild.
The five speed used on the XK was the Rover derived box. The Getrag was used on the 3.6 XJS.
