Gearing - the standard box has pretty long ratios, adding ~1,000 rpm to each gear would make them intergalactic.
Also, the engine is going to come on cam from around 4,000 rpm, then scream past 8,000 before fuel cut forces you to grab another gear.
Long gears are not going to work here - they'd take forever to get into the power band, and when you change they'll drop you out of it again, a recipe for frustration.
The stock box is, frankly, somewhat of a pain here- it requires a fairly hirsute press to get the gears off the shafts, and of course back on again.
Albins (in Skippie-ville) make gearsets which can be swapped in, should you have an Esau edition press in your workshop, and said gears are helical so should be fairly mild mannered.
There is also the option of straight cut gears from the likes of Guard, but I'm uncertain that I could cope with the noise (beyond what would undoubtedly be the hysterical first drive).
We did look at using the GT3/turbo box, but the different dimensions make this very difficult (and conversations with companies such as Quaife revealed that they'd tried and failed to convert their Cup box to work with M96 variants), so modifying the stock box appears to be the way forward.
Current plan is to dyno the engine, then extrapolate the required ratios from the shape of the curve that we get, in order to drop into the power band each time another gear is selected, then order a stack of suitable gears from Australia.
Somewhat undecided as to whether it would be a good idea to make the whole box very short, or leave sixth as a much longer gear for cruising on the motorway.
