Just bought a 3.0SC for my 914 what do I need to hook it up and make it work?
Hello everyone, I just bought a '83 3.0 SC ($2500 running complete, I'm happy) and now I am going to install this into my 73 914. I have highly reasearched the whole 914-6 conversions and I know early Porsches very well. I bought a 2.7 and had it rebuilt then decided what the hell I am going to buy this 3.0 (2.7 is for sale). I bought the engine with all CIS, shrouding, exhaust still on it (it was started and run in front of me prior to removal).Engine also has: turbo valve covers, pressure fed tensioners, pop of valve.
My question is what do I need to hook this up to my 73 914 electrics, fuel system etc? I know I need a matched fuel pump (anyone have one for sale?) do these need a line to and from the fuel tank?, I guess I need a brain (what do these go for?? anyone got one?), do SC engines use the 6 pin CD box?? I have a 3 pin but I guess it won't work. Will I need the relay board out of an SC? (if so what do these cost? anyone got one?). Will I need the O2 sensor? What else do I need to consider to hook up all elelectrical and fuel components of this engine?
I have a pair of Weber 40 IDAs I plan on installing in the future, I was thinking it may just be easier to leave the engine together and run the CIS for now. Does anyone know what jets and venturis to run with a 3.0SC maybe F3 tubes? anything else needed?
I will also need 914-6 headers. What size should I run? 1 3/4" 1 5/8" ? Does anyone know the value of a complete used 3.0 '83 exhaust (california if it makes a diff). Whats the value of the complete 3.0 SC CIS injection system?
Where can I get a 9 bolt 3.0 flywheel that will fit in a stock 901 914 transmission? <img src="confused.gif" border="0">

you might as well put the webers on now. considering the cost of the CIS and electrical components, and the time required, you will be way ahead. patrickmotorsports.com for the special flywheel, mounts, exhaust, oil tank, tin, etc. not much value on the old exhaust and intake.
