Out with the old, in with the Blue... Finally got around to getting rid of those terrible bronze calipers. They may look good behind different wheels, but bronze on bronze was a bad decision. These calipers were the only thing I disliked about the car.
These are absolutely m14x1.5 with a 60 degree conical seat. The overall diameter of the new nut is a little smaller than the OEM nut. The OEM nut has a wear mark under it. That is .9", the overall diameter of the cone of the new nut is .8"
That's my only concern.
I bought a set from the local AutoZone today. I just wanted to swap the stock chrome for a black set. These looked smaller. Initial inspection:
I put my caliper across the taper and it was .8 vs the OEM at .9 of the diameter of the bite marks on the lug.
They also weren't as deep as the OEM...
I get it, but 7000 is premature... It's a 4BW. I did find the gaps to be way too big, re-gapped and it feels 100% better on the butt Dyno. My only concern now is the oil I found on the front plug on each bank. The other 4 looked perfect. Could a fouled plug kept unburned gas build up in the...
I have the JB4 and new colder plugs. It was a night/day difference. I want downpipes too. I thought the TB would complement these mods, but not sure how much.
Ok all, here what I've found. All 6 Brisk plugs were gapped wrong out of the box. I found gaps from .030-.036. I closed them all to .024, cleaned them up and took her out for a shake down ride. She idles smoother, and fuggin' rips all the way up to 126mph before I shut her down. I think it's all...
I used tons of dielectric grease when I installed them... Just to be sure. I'm pulling them tomorrow to verify the gap and see if there is any trace of burned spots or any other indication of fouling or grounding. Is there any harm in closing the gap a bit? I feel like I checked them at .028...
