    This is what I used as far as wiring. Double check your resistor pick ups. Double check your wire connections. I was using a GM weather pack plugs and kept losing sync. So i took that off and ended up using the stock round datsun dizzy plug. Then butt connectors with aluminum foil wrap to make sure no cross signal.

    Planning on going to Z nationals. Before I go I need some things updated.

    1 - brakes
    The z32 brakes work to good. Using the z32 master cylinder and booster I am getting an over boost on the brakes, meaning initial stopping will almost always lock the brakes up. If you really concentrate you can stop without doing it. So I am going to put a stock master cylinder and booster of a 280zx. Size difference is over an inch. Hopefully this eliminates that issue.

    2 - seat belts
    I have done some time attacks with car. The stock seat belts do not hold me in place. So I am getting race harness 5 point seat belts. If you watch my videos earlier in this post you will see what I mean.

    3 - radiator over flow
    Don't have one, will install one. Don't know what bit will be searching the pick n pay for a suitable one.

    You can use a ZX Booster if you can't find what you want. I installed an 83zx booster in my 260z it fits in it upside down, it doesn't know the difference. :o)

    What master cylinder did you use with the 83zx booster?

    First time at the drag strip, got my times.

    I did a lot with street tires. If radials I had some good luck running high pressure. 35lbs. As Rebekahsz said control the tire spin but don't burn the clutch. When setting the second bulb use the e-brake to stage. Hold the button in and try to pre-load the driveline. This eliminates the shock load value when putting the power down.

     

    When launching the car, release the e-brake all the way (don't need full on braking) at the same time you engage clutch.

     

    Tough issue is boost and lag. I was able to get under 2.0 doing this. 1.94 being the best. But that would put you in the 13.6 to 13.8.

     

    Practice.
