Cruez Posted March 23, 2004 Share Posted March 23, 2004 Ok guys... Trying to get the car going... got the gear reduction starter in... finally.. The compression has been increased to 10.25 from 7.8... or whatever the stock 2.8 L6 was in the 280Z.... Running a Haltech EFI setup. The coil has been replaced with a MSD blaster 2 (no I don't really like it)... Now... My question is, should I decrease the spark plug gap a bit since it will have a more dense charge than originally?? Quote Link to comment Share on other sites More sharing options...

tec280zx Posted March 25, 2004 Share Posted March 25, 2004 Right now i'm running a f54 flattop/N47 combo and I use a .45 gap for my plugs. I've tried going bigger but it tends to miss at higher rpms. Stock ignition btw. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted March 25, 2004 Share Posted March 25, 2004 Let's hope that is a 0.045" gap. Fiddle between 0.030" and 0.045" and see if you have any misses. Run 0.045" if you can get away with it without any misses. Quote Link to comment Share on other sites More sharing options...
Savage42 Posted March 25, 2004 Share Posted March 25, 2004 You should be fine with that gap, as I ran that with my Electromotive setup. The key will be whether or not you should go with a cooler plug. High compression on warm days with hot plugs will cause detonation. Just thought I'd pass that along.

Cruez Posted March 25, 2004 Author Share Posted March 25, 2004 When I originally built the car... I made the mistake of using Bosch platinum plugs in it..... they lasted a grand total of about 10 minutes..... Tried a set of Bosch Supers after that.... they lasted long enough to drive from the muffler shop and not quite back to the house before starting to foul out... I ran a set of NGK R BR6ES-11 plugs for over a year in that setup and they ran great... I'll startout with .042 or so and see what happens... Thanks guys...
