The car absolutely rockets off the line whereas my ultra close 56A 5spd had a huge 1st gear and was really all about 2nd/3rd/4th and 5th this one is all about the 1st 4 gears with a bit of ( but perfectably acceptable ) gap between 4th and 5th
Just abit of clarification so not to add to the misinformation about the 56a 5speed gearboxes already..
There was never an "ultra" close ratio 56A 5spd offered from datsun competition/ nismo. However there was a mid close and ultra close 56L (F4W56L) 4spd gearboxes offered.
Did u mean a 56a 5speed with a custom ultra close gearset?
what were its gear ratios and what diff ratio did u run with it? Doesn't make sense for an "ultra" close gearbox to have a "huge first gear".

is this bettany 60a gearbox already in your car or is it being reconditioned/built?
as for the 60a gearbox,that bettany gear info you gave is priceless.Might go down that route with my 60a gearbox. How much did the custom mainshaft gears cost? Im hoping helical gears will be cheaper as i wouldn't want to run straight cut gears on a street car.
I'm also eager to know if the cluster is a one piece machined item or custom gears welded onto the shaft.
Rallytwit,
If possible enquire if bettany gears can get the 60a gearbox to a direct fifth gear 1:1
Would be more efficient than an overdrive for your application.
cheers
