Buying an engine tomorrow!!!

Postby Mr0erick0 » 25 Feb 2017 17:17

Hey guys/gals!

Need a somewhat quick response haha
New to the Datsun restoring game and I'm just wondering if an L16 4 speed tranny out of a 521 would fit into my 68 510?

In short - yes.

But you will need an L16 510 oil pan and pick up, I believe there are minor differences. The gears in the 521 transmission will be slightly different with lower 1st and second gears, making the 2-3 shift a bit taller.
There might be a difference inthe fan onthe water pump, best to use the L16 one.

Otherwise you are good to go.

The transmission ratios are identical to the 510 wagon. I would call them a wide ratio and the sedan a mid ratio gear set.
3.657 for the 521 and wagon and 3.382 for the sedan first gears (all 4ths are the same). This will give a little more snap off the line but you will be shifting before you get to the other crosswalk.

The rear of the 521 4 speed will have (or most likely will as it's easier to remove this way) a splined bolt on drive shaft flange for the U joint. You'll have to unbolt and remove this, but a 510 driveshaft 'slip joint' will fit just fine.

The 521 and 510 use the same water pump but the fans unbolt.
