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.
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.
