Does anyone know if there are any coil over plugs that will fit the 928? ie ford or what ever?That would make it a lot cheaper to do.but i have no idea. thanks,Ray

Somebody did this, using an aftermarket ECU solution. IIRC, they might have used units from a Cayenne?

Colin used cayenne coils with his VEMS computer.... But he had issues with them. I use LS truck coils for CNP coil bear plug on my 16v .

The cayenne coils are a pita to use.
2.0L turbo VW could work and fit ok, much easier to trigger them.

Apart from the perception that COP's seemingly fail more frequently, is there anything to suggest that the stock 928 external coil based system is less than adequate other than the leads fail every 10 years or so?

When we redid the ignition on my 91 GT we used Porsche Turbo units with the Autronic ECU we installed.

Is that the car build by Bob Payton and Ed Kowbel?

eboarini

Yes, it is. It's finally complete and back on the road.

RFJ

Is there anyway to access the work done on the car?

Ducman82

are you asking how it was done? full aftermarket ECU for starters. is that why you have and or planing on doing?

Ray, it would help if you gave us some details on what you are trying to do.

RFJ

Just trying to gather some information on this to know which route to take on my 86.5 that i am putting back together and the you fellows have given me are a big help.Ray

RFJ

I don't get it the link you gave me goes to one area then jumps to another.I got it goes to 2nd page then jumps to 4th. and that car with all that red really jumps off the page,wow.

RFJ

Thanks for that.

The picture with all the red was from the completed rebuild using the COP and the original intake. Following the break in we installed the twin screw and the intercooler. Here's a pic of it with the twin screw.
