Changed out the distributor in my '81 280zx turbo. Using a dist. from an '82 turbo.
Car ran but was off timing. Couldn't set timing, not enough adjustment. I'm wondering if I may have screwed up when I set up the oil pump. I did bring it to top dead center, and it was pointing to number one.Piston was up in number one cylinder, however it won't make an attempt to start. Any suggestions?

you could have set the oil pump shaft for #6 compression.(It looks just as same as #1 TDC) set the distributor to #1 position (rotor botton facing 11 o'clock) and take the valve cover off. You should have the #1 intake closed( facing up). If not, put #1 wire in the #6 distributor cap and replace the rest from the in order

Just back up dist 1 tooth. Hold on to dist and have someone tap ign. till dist drops all the way down. The dist. drives the oil pump but there not timmed together. Your dist. will take its first drop then stop if the oil pump drive is not perfect thats ok just tap the key untill it takes the final drop. your still in time since your dist. gear is locked in with your cam.

Someone please correct me if I am wrong, but I am under the impression the 81 turbo distributor uses a Crank Angle Sensor that is mounted on the lower front of the block.

The 82 and 83 turbo has the CAS inside the distributor.

Are these dizzy's interchangeable?

If you removed the oil pump you will have to check the position of the "tang" on the oil pump drive shaft. With the engine at 0 degrees TDC, # 1 cylinder at the top of the compression stroke, both cam lobes pointing up, the offset "tang" should point to 11:25 o'clock. You can also place a screwdriver across the dizzy mounting surface on the block. With the screwdriver behind the top bolt and in front of the bottom bolt the "tang" should be parallel to the screwdriver.

You have to drop the oil pump to correct this, line the timing mark on the pump drive gear up with the oil squirt hole in the pump housing. Without moving the shaft slowly re-install the oil pump. Just before the drive gear touches the crank shaft rotate the oil pump one half of the diameter of the bolt hole in the pump clockwise. This compensates for the counter clockwise rotation of the shaft as the gears engage. This is easiest to do by placing one of the bolts in one of the pump holes, when the bolt touches the block rotate the pump clockwise push the pump in then rotate it back and screw in the bolt. Now check the "tang" alignment at the distributor mount hole with a screwdriver.

When you install the dizzy the rotor should be pointing approximately at 09:00 o'clock.
