Fairlady - update

It's been a while since I posted any updates. I haven't done as much as I planned to by now, just been busy with other things. All I have left on the motor is installing the distributer and valve cover so it is basically done. I cracked open the diff and started cleaning up the 39 years of grease from the diff housing. Everything internally in the diff is in really good shape and the magnetic oil plug did not have any metal deposits.

The drum brakes are in decent shape and I would probably be okay keeping them but I went ahead and ordered the disk brake upgrade from silvermine for all four corners. I also have a set of tokico hp shocks (non-adjustable) and springs on the way.

Oil pickup installed:

The oil pan actually turned out to be a real pain. The ARP studs on the rear main cap were taller than the factory bolts and there was an indention pressed into the oil pan that was in the way. A few minutes with a hammer solved that problem.

Fresh set of NGK BPR6ES spark plugs.

Current state of the motor.

Diff housing after some cleaning. Almost ready for paint.

 

 

 

The early JDM Z cars have shorter 3.9:1 gears to make up for the lower displacement of the 2.0 Liter L20a. This may be interesting with the L28.
