rsr distributor cap for Andial twin plug

Does anyone who anything about this cap, rsr distributor cap on ebay. I've seen a couple of listings for this.

New Porsche 911 RS RSR Carrera Twin Plug Distributor Cap | eBay
I'm chasing down a high rpm miss in my 930 3.5 twin plug currently running an Andial RSR 12 plug distributor. The cap & rotor have about 13K miles of use. This uses the black cap.

This is a Marelli Cap as fitted to the Maserati 3500GT and to the 911R on the S121A Distributor and the 2.8RSR with a Marelli S121B Distributor.

They have been re-manufactured by the Maserati Club International for the last few years along with a compatible Rotor Arm.

They are normally about $270 so $200 is not a bad price.

I believe that the Andial Dizzy Conversion used a 3.0RSR Dizzy cap which is Bosch rather than Marelli and is potentially incompatible with the S121A & B Type caps.

The last time I spoke with Andial they had both black and Brown Caps in stock and on special offer.

The Bosch Cap is 3 lug but I am not sure if the diameters and heights are the same as the Marelli and it is an expensive experiment to find out.

RSR911.de in Germany make a replica Bosch 3.0RSR Distributor with cap and rotor but I am not sure if they sell caps and rotors separately.

If you have a Marelli dizzy you can also fit a late Jaguar XJ12 Cap but you will need a different rotor which I believe can be obtained from Burnham Performance.

Jag caps can be had for around $75

Thanks, I have the 3 lug Bosch. I didn't know I could still gets parts from Andial. Anyone know what the life expectancy of the cap & rotor are. They were installed in '06 by Andial, and have about 13K miles. I paid about $1100 for the cap & rotor back then.

Andial is LONG out of business, now.

Porsche Motorsports bought the name so if you need the Bosch RSR cap and/or rotor, you might contact them to see if they can source them for you since Bosch Motorsports no longer has them.

?!?!?! Bloody hellfire! Just for the cap and rotor arm?

...wonder if somebody has 3D printed one yet?

This guy seems reasonable (relatively speaking). shop
My goal is to sort it out, then swap over to a Electromotive XDI.
