When my z gets shut down after a full
warm-up drive it runs awful for about
five minutes after being restarted.
Is this because heat rises to the OHC?
Or is this from lack of oil at restart?
OTHER?

This is probably due to the fuel in the lines vaporizing due to excessive heat. A fuel pump cannot pump vapors. On the ZX's Nissan installed a blower to cool the fuel rail when the engine shut down. The 260Z's had a problem w/this as well. You may need to insulate the fuel lines and rail from the excess heat. Good luck!!!

My '79zx does this too,I plan on wrapping the fuel lines with some stuff availible from thermotec, not sure if this is correct but as far as I've been able to find out so far in '79 models the aux. cooling fan came on air conditioned cars, I have no a/c and no aux fan, am looking into what it takes to equip mine with one, looks like the wiring is there for it, but no timer relay under the dash and such
