Twin plug info

Bucketlist · Bucketlist's Garage

Looking for info on the twin plug engine and 4 speed in my 930 clone. Engine#6860370 Trans#77F0068. Does anyone have a way to look this up and tell me what vehicle they came from? Also the 1981 911SC was imported in 1987 so I am wondering where it came from. WP0ZZZ91ZBS100510.

I'm confident there are lots of people here who can help (I am not one of them) but you'll need to post better pictures for some chit-chat to begin.

Twin plug was never standard on a stock 930 engine. I suspect yours has been rebuilt and modified. You would need some information from the previous owner or engine builder to really know what is in there.

If you post better pictures we can help identify the twin plug system. What is the engine type? It is on the horizontal portion of the case below the fan housing cradle engine number. Usually its partially covered by the cam oil line.

That's a Ruf intercooler & airbox, for starters.
Do you have a Bosch 12-plug distributor with twin coils, too?

Yes Bosch 12 plug distributor, coils & CDI boxes. Has newer K27 Turbo.

More pictures please! I believe that Ruf intercooler is quite valuable these days. I would hold on to that little dude.

Powerhaus Headers

Those look like GLH headers. All the "Powerhaus" headers I've seen are rebranded B&B headers.
Powerhaus... defunct for a long time now and BFD.

Those predate GHL. GHL never used those nice flex bellows.
Probably are PH, from when B&B was just starting, or before there was a B&B.

They also seem to have a serial tag in the same spot as my old ones.

Sorry for the time lag, I was a little slow to catch your meaning of engine type. It is 930/51. Can you tell me anything about this engine?
