pual i have never met you, i am sure you make good pizzas, but regarding s2000 fitment making a 1200 have 1 forward and 6 reverse gears. Check a school book because the diff goes both ways and the gearbox makes the car go forwards and back!

just thought i should point this out! we don't want any accidents from poor workmanship now do we?

An S2000 fitment to Datsun 1200 sounds interesting indeed, but just not easily compliable in Australia!

Ummm, maybe we should think about this matey. As a sparky, I assume you know very little about mechanics, so no hard feelings!

If the engine rotates in the opposite direction, and you are running a standard diff, then there will be more reverse gears, it all depends on what side the pinion is to the crownwheel in relation to which way the engine spins...

A differential is called what it is because it changes the 'direction' of the tailshaft spinning to the axles, and this can be in either way....

If the pinion is on one side it will spin back, if on the other, forward, logic! This is found in plenty of school books!

There are some older model trucks with diffs that can be put in wrong resulting in lots of reverse gears!

Gearboxes use idler gears to go into reverse, 3 gears instead of 2. Driver gear transfering to the idler/middle gear changing the direction to the driven gear = Reverse.

The s2000 gbox would suit the direction of the s2000 engine and Diff. If different, would not suit the Nissan/Datsun rotation.

Assuming you use a s2000 engine and box, you would need a diff to suit its direction.

Have a little think about it....

Not only can b310gx make good pizzas, he has actually taught you something you thought you knew!

Personally I would be looking into a more promising diff for the application.

Cheers!

dude VERY TRUE! my apologies to B310GX! I guess i was just thinking of pizza!

no worries phunkman,do you want garlic bread with that.ok,best example of engine direction was the land speed record car built by norman 'wizard' smith,a little known competitor today.he used a napier areo engine,but because it spun in the 'reverse' direction to normal,they fitted a transfer case behind the gearbox to get forward direction.as the rearend was hand fabricated,the author asks why they just didn't turn the ring & pinon gear over,thus saving a lot of weight.all this took place in the thirties,& the record attempts took place on the north island of new zealand.also,ask a volkswagen mechanic about putting the diff in backwards in a beetle,this produces the same mayhem.by the bye,any new zealander's may know him as 'windy' smith.
