Hi Albert,
For a four-stroke, six cylinder engine,
it takes two engine revolutions to fire all six coils.

Good question. I have a Nissan
inline-six cylinder turbo, and I removed the stock EFI and replaced it with an
aftermarket one. I went completely distributorless, and I'm running six
Denso coils (taken from a 2003 GMC Suburban, an LS1 engine) so I can run "coil
on plug". They have integral ignitors and I don't have to run "wasted
spark". I also run six Mazda RX7 injectors that can now fire sequentially
(versus batch-fire in the old Bosch L-Jetronic EFI). I'm a sick
gearhead. ;o)

be somewhat caught up in the whole gearhead thing (to say the
least)...........counseling is an option you know, but if you are happy in your
addiction then I say....have fun!

Hi Chicoman,
Yes, you are correct. It is a 1982
280ZX that I've been modifying over the years. I installed a KAAZ limited
slip differential that was pulled out of a Nissan 240SX, so the inside tire
spinning going around a curve has been cured. ;o)
