Is there a general consensus on an upgrading to the coil, dizzy, plugs, wires etc for the 2.6?
The engine is a fresh rebuild.
Mild port & polished head, schneider springs, .020 over , weber 38,ceramic header, and 2 1/2" stainless exhaust no CAT, into a 6" Walker Ultra Flo muffler.

With everything else that you've put into the motor I don't think it makes sense to leave the ignition system stock. I'd upgrade the plugs, wires and coil with high performance parts (I prefer ND Iridium plugs & Magnecor wires personally) and go through the distributor thoroughly, making sure the advance mechanism is working properly & installing a quality cap & rotor.

I'm upgrading everything I can think of as long as it keeps it better than stock.
I've been eye balling the Bosch Red Coil, it's getting a new distributor, cap, plugs and wires. I've heard the NGKs are the way to go with these??
I have a set of Taylor Thundervolt 8.2mm plug wires that came with it. But have never used Taylor before

There is significant concern in the air-cooled VW world about the quality of the Bosch coils varying widely depending on where they are manufactured (I think it was Spain vs Brazil). I'm not sure of the details, but some of the Bosch coils have an abnormally high failure rate. I'd do more research on them before I bought one.

On my last 2.6's, I used an Accel yellow SuperCoil, and it worked just fine, for about 150kmiles. I'm very fond of NGK plugs and wires, plain vanilla plugs work just fine. I've had problems with the unobtanium plugs. The center electrodes are very fragile. I had a glass bead blaster plug cleaner, and I'd pull mine and clean them up and regap about every 5k miles. I've used taylor wires in the past, the common vanilla kind, and they were decent wires, but not as good and reliable as NGK's. I had bad luck with Magnecors, fragile connectors, mostly...

On the accel coil, I bypassed the resistor and wired both the on in start and on in run to the coil +. You take the wire off the bottom of the resistor and move it to the + post. I found I had a much more stable idle and no spark fade at above 5k rpms.

I'll look into the Bosch thing, thanks for the heads up. I've also looked at the Accel Superstock High Vibration coil. I've usually had good luck using Accel wire, but NGK seems to work good with Japanese engines.

Appreciate the feed back. This thing is costing me a fortune. And it was just a parts buggy. Oye
