Well today got a little bit done. The original vacuum source I was using wasn't very good (kPa value would freeze soon as the TB closed). So I found a different spot and tapped it from there.
Also decided to work on the sync issue as well. I was told to double check the base ignition timing on the car. So I looked up how to do it and went to it. Should be set to 10*. I found mine was sitting at about 12*. Clocked the dizzy and set it up right on 10. Here's a little how to if anyone ever needs to know how to set base timing on a 2JZGE.
- Find the diagnostic port in the engine bay, and jumper terminals TE1 and E1 with a paperclip.
- Connect the timing light to the battery, and to plug wire #1

- The timing marks on the plastic cover will read | 10 | 0 (this is in increments of 5 so it read it as 15 10 5 0 ). With the pins jumpered, you want it set at 10.
- Point the timing light and look for the line on the crank. It should line up at 10. If it does not, there is a single 12mm nut you need to loosen on the distributor. Clock the dizzy until the mark lines up.
- When you're done, tighten the nut back up on the distributor, and check the timing one last time to ensure it didn't budge while tightening the distributor. Remove the jumper. With the jumper removed, you will notice the timing will advance a bit automatically which is normal.
