Does anyone have an idea of the cost of converting a 928 S4 to a manual transmission?

I understand that a different subframe is required but that the conversion itself is simpler than most.

I've read about a company in the states that makes a kit so you can use the Corvette 6spd transmission, think the cost was around $6000

Might be worth talking to Paul Anderson in Gloucestershire, I think. He races 928s and has converted several to manual transmission.

I would think one of the main limiting factors is the number of available gearboxes and associated bits (unless you're thinking of a non-original).

+1 on talking to Paul Anderson (928spares.co.uk) if you can get hold of him as he does have the experience and might even have the parts.

Also not sure why it would be easier than other cars, you still have to change the firewall/pedal box to install the clutch etc.

I'd herard either correctly or incorrectly that the apertures in the firewall are already there for both LHD, RHD & manual & auto (I assume with grommets in place for any unused openings).

I'd have thought that a Corvette six-speeder would be stronger box than the original which can experience considerable wear to the second gear synchromesh even on a car in a standard state of tune.

Thanks for the responses.
