Nismo Tune too hot for nitrous

gbrettin · 12-25-2014, 04:22 PM

I was planning on going one step colder with my plugs in the spring, possible GTR plugs.

Quite possible true about the micro damage, but I plan on doing an engine rebuild in two years so I can accommodate high boost. I could tear down the engine and post pictures then.... But if there are any micro fractures it really wouldn't show.

My car is out only Spring through Fall so the winter temps don't help too much

I'd at least look into 1 or 2 step colder plugs (and lots of tuners swear by copper ones, although I think stick with iridium and colder... ask Z1?) and if you are running 91, find 93 or higher when you plan to spray. You might look up a blending chart and add a 1/4 tank of 100 pump gas if you can find it to nudge up the AKI.

Winter temps in Michigan will help too.

Good luck!
