I have an later e88 with SUs and ZX dizzy, e12-80 on my 240. I've read a lot of different stuff on the plug gap. Half say go with the motor and the other half say go with the ignition. Motor says protruding with .035ish gap. Ignition for '79 says non protruding .044ish gap.

I like to think it has the strong spark at .035 protruding for carbs. I opened them up to .042 on bpr6es-11 and it didn't run too good. What do you all think? I also read that a closer gap on the 1.1mm would angle the tip downward too much and you don't want that. I think I should buy these instead of the 1.1mm

Thank you for any input.

Hi, I always use the standard BPR6es-11 on my standard ignition with nos contact points. I think it will depend on what ignition coil your using i would go with the bpr6es-11 sparkplugs when you have a orig. coil.

Btw, the 280zx i got has that orig dizzy, and uses also the same plugs runs great with -11 plugs. (1,1 mm Gap.)

You could buy those 0,9mm plugs and if it does not run right open them up to 1 mm or so..

(If you have the 123 ignition coil.. my opinion? throw it in the BIN! and get yourself a orig. coil.. ;-) )

I'm using a Crane/Fast PS20 Fireball with 1.4 OHM coil, no ballast resistor. I wanted all that old stuff gone, I've never fooled with points except file down the contact point on my go-kart. Cool little file too.

It starts missing with the wider gap up high but from what I remember I've always ran the wider gap? Grasping at straws, the easy ones.
