D motor cycle style shift drums are very simple, you wouldn't need anything more than a control cable.

My MR-S has a steering wheel shifts, its a hoot but
the setup is very complicated if something goes wrong.
There are hydraulic pumps, solenoids, ecu and hoses
that run this system and motorbikes are mechanically
operated which is infinitely better simpler etc.


Years ago I wondered if one could use the strong drag
harley davidson aftermarket boxes onto an A series
they are cheap and stronger than some japanese boxes

140 ci or 2.3L twin has a fair bit of torque!

175lbs!!!!!!

torque rating is the key element and 2.3L
would have more torque than any A series.

At last there's a solution that reduces vibration and improves acceleration. When the bike hits freeway speeds, simply shift into 6th gear and lower the cruising RPM. Freeway cruising becomes more enjoyable with reduced vibration, increased gas mileage while keeping the engine in the heart of its torque band.

Paddle shift kits would be a hoot.

I gave thought to this many years ago because as I motorcycle guy / racer first I've always thought H pattern gearboxes are an abomination (no strong opinion there)

So here is my deal on sequential boxes; with the motorcycle powered sports racer once I left the pits I'd go up and down the box with out using the clutch. This naturally allowed me to left foot brake. While I'm capable expecting flawless heel and toe downshifts I don't get any big thrill out of it in and of itself.

On the surface it seems simple enough to come up with a shift drum mounted externally to move the shift lever but what do we gain from it........ Besides the cool factor of course.

One possible thing I can think of is paddle shifters making it easier to keep hands on the wheel while shifting.

S1 Sequential makes a really nice kit for the Tremec T56 but I would like to see if our community could come up with a similar idea for the Datsun.

This would be a very fun item to DIY

After a crack at the cross flow head BTW.
