Hi Richard,
The extra 500cc was obtained by increasing the throw of the crank. In most other
respects the 2500 is similar to the Mk2 2 litre engine - there is a substantial weight
penalty for the increased throw on the 2500.

You will need most of the GT6 or Vitesse runningh gear to do the job properly (and
safely).

Neither. Some people have used the 2500 type box, but the gearbox output flange will
sit higher than on a Spitfire or GT6, so you will have an upward offset in the
driveline. This means that the propshaft no longer has the optimum straght run front
to back - possibly not a problem but a factor that ought to be considered in getting
everything as vibration free as possible.
The best solution is to use the Vitesse/GT6 gearbox, though I suspect you ought to
uprate the overdrive to a J-type as the D-type is at it's limits with a 2 litre engine.
> Engine and gearbox mounts - does it bolt straight down to the same mounts?
Soe of the big Saloon engines did not havbe the Vitesse/GT6 mounting bosses drilled so
you would need to do that. The mountings themselves are not the same as the 4
cylinder, but they are readily available for the VitesseGT6 - are you beginning to
spot a pattern here?......
> What else would I need to complete the job? I assume:
You really are best off starting witha scrap Vitesse or GT6 as there are so many minor
(and major) components which are essential for a project like this. The front and rear
brakes are different (as is most of the front suspension), you need the correct
radiator - to do this without a donor would need a substantial budget just to obtain
the raw components.
If you want specifics about this kind of conversion then drop me a line off-list and
I'll put you in touch with a couple of friends who drive 2 litre and 2.5 litre GT6
Convertibles,
Cheers,
Bill.
