Spark Plug Gap

[Alec]

I am installing my spark plugs right now and was wondering what I should gap them to. I already searched with no luck. Some say .032, so say .028. They are NGK V-Power Copper, stock heat range. Car is an 89 Turbo, mods are in the sig.

Thanks

TSRM is your friend. When in doubt, go there.

I went there. I know what stock gap is, I just want to know if you guys recommend something different. One of my buddies says .028 and some say .032.

stock gap. you only start closing the gap when you run high boost levels and start breaking up.

Yeah just run stock until you get some more mods. I run .30 with my 400rwhp and it's fine. When I go to the track and do some pulls on high boost I run .28.

Define "more mods". I"m planning on running the stock turbo, maybe just BPU mods like DDP and test pipe, EBC, intercooler hardpipes, and Spearco Replica. That's about it.

Just run stock gap, reduce it if you start breaking up like mentioned above. If your ignition system in good condition you don't have to close the gap only because you are pushing 300-400 whp
