cis needs total rebuilding

Had a friend who works on Porsche's over to look at my 82sc. He did the pressure checks and every thing was way off. He said that it looks like the CIS was modified in the past. However, I knew this was a running car prior to it being parked 4 or 5 years ago. He found a two prong plug laying on top of the motor under the air box that was disconnected and taped up. Could not find where it went. It has a brown ground wire and a red with a white stripe wire. He also feels the the auxiliary air valve was removed and plugged. He said it looks like a factory modification, but it should be there on an '82SC. He said the chain tensions were upgraded and there are many new bolts in the exhaust system. He feels since the fuel tank and fuel pump were all gummed up from old gas that both the WUR and the fuel distributor need replacing. He recommended finding a good used CIS unit from a running '82 and replacing just about everything involving the fuel system.
He recommended one other choice. Sell the 3.0 engine and put in a 3.6 and all the upgrades necessary at a cost of about $15,000 to $20,000.
The Weber's sound like a better choice to me.
