And indexing. Although that takes a little long if you don't get the washers

Nahhh I don't do washers anymore. I just screw in the plug, if the ground electrode is blocking the intake side, I take it to the next cylinder. Takes 10 min at most

The Wayne Cox HP Trick

SE-R.net is gone, luckily Waybackmachine has got it. I should mention this mod is only for B13 distributors, I've tried to see if it's applicable to b14+ distributors and it doesn't seem so.

"Here's what'cha do: Remove dist. cap. Remove rotor; be careful, if your rotor is stuck on the shaft *do not* twist too hard on it. You can break it like I did There's a screw in the end of the shaft - loosen, twist counter-clockwise against the bolt slop and retighten. Put the rotor back on and twist it counter clock wise while tightening. I slotted out the hole in my rotor for some extra adjustment. I verified this using a cap with a hole cut in it and a timing light to see the position it fired."

He also had a disclaimer that said this works on the '91-'93 SR20s but wasn't sure about the different distributors on '94+ SR20s but that it should still apply.

Sounds more complicated than it actually is -- takes maybe 15 minutes.
