I'm looking for information on dropping a 3.0 SC CIS-injected engine into a 914.
What's needed for the wiring? Other parts required? Impressions? What did you use for heat exchangers? Did you have to add an external oil cooler? Front mounted cooler or fan-cooled mounted elsewhere? Thanks. |

Fitting the fuel distributor will be an issue. You'll need th rotate it 90-deg at a minimum, maybe mount the engine a bit lower too. Worst case you'll need a custom intake work (search others that have done it)
Wiring - Perry Kiehl makes a conversion harness (I believe) Heat exchangers work w/o issue. External cooler is recommended, front mount is best, but if mostly street driven an under rear trunk setup with thermostatically controlled fans will work. |

Had a 3.0 CIS in my last Six. Ran great- no issues at all. I did add two small VW oil coolers (no fans) where the fog lights come stock. Ran it all with stainless steel hose and a turbo thermostat. That car never got hot always ran between 180-190. Plenty of power and no fuel smell or constantly messing with the webers that occupied the engine bay prior to the 3.0. I also ran the factory heat exchanger and the stock Six muffler slightly modified to resemble the GT muffler. Car sounded killer.

I have a slowly developing project to put a 2.7 CIS engine in my 914/4. Assuming this is going into your 914-6 you will also need a an adapted flywheel. Your existing 914-6 has a 6 bolt crankshaft and the 3.0 has a 9 bolt crankshaft. Patrick has an appropriate flywheel available.
As far as an adapter wiring harness is concerned there is very little that needs to be added/changed. The CIS system is really not an electronic system which makes the adaptation simpler. In my 914/4 I am currently using Megasquirt FI and that will be my backup plan if I have problems with CIS. Darryl |

why not just call KEP and have them make it rather than deal with patrick and the associated prices?
Im not sure i would keep the CIS though. |

That sounds like a fun project.. I know when I did my 2.7 conversion I ditched the cis for carbs but had I known then what I know now I would have just rotated the fuel injection 180 degrees.

Since the 3.0 is out, I hope you get to install 964 cams in it for the little extra ponies. |

On my 2.7 rebuild I plan to use a 964 cam grind and JE 9.5 cr pistons. The combo with CIS should be good for about 200 hp. Once I get going with the project, at least a couple of months, I'll start a thread on it.

No cutting required. I made a custom intake using an early Volvo 242 intake base and fabricated an intake elbow. Wiring was not complex you just need to focus. We removed the fuse panel. Added a fuel pump relay and a tach wire from the back. I put the computer under the passenger seat and added a sensor bung on 1 58" headers.

I tore the CIS off and put on Webers for my 3.0 /6 conversion. It sounds better, looks better, performs better, easier to work on, and makes the conversion itself a lot easier with fewer electronics and sensors. But your MPG goes down and fuel smell is indeed an issue. I don't care about MPG but sometimes the fuel smell is annoying. Regrets? None.

I have been reading up on oil coolers, the need for them and where they can be successfully placed. It seems that a rule of thumb that has been thrown out is that anything larger than a 2.7 running FI needs an external cooler. Obviously, I won't do anything that can't be bolted into the car and then removed but weighing the options is difficult.
OPTION 1 - Its a given - I have my carbs rebuilt (they need to be rebushed). Once I do this, I could simply put them back on the stock 2.0 and drive it. OPTION 2 - Or, I could pull and pickle the entire engine and carbs, and spend the money to have the carbs rebuilt towards a complete FI engine. I've found a 2.7 CIS, a 3.0 CIS and a 3.2Motornic all for about the same money going in.....but then there is the whole oil cooler issue. OPTION 3 - Have the carbs rebuilt but set-up for a larger, say 2.4 carbed engine (again, found one of these for about the same money as in option 2 but its rebuilt). This approach would be more $s overall because I'd be rebuilding the carbs and buying a motor but there would be no need for an external oil cooler and it would suit the character of the car better than turning it into a monster. Thoughts? Any recommendations on where to have the carbs rebuilt? Because of the shaft play, they need to be rebushed so its not something I'm ready to try. |

You won't know for sure about the external oil cooler ( no matter what the engine size) until you run your car. Some engines rune hotter than others and where and how you drive matter. Your in GA, not ME, count on a cooler no matter what. I would buy the engine for the engine, not to save money on an oil cooler.

Based on my small brain, anything over a 2.7 should get an oil cooler....unless you happen to live in Alaska. As for the carbs, Paul Abbott in N Cal can rebuild the webbers for approximately $2700 - $3000, especially if the shafts need work.
I would dump a 3.2 and drive away with a Big Smile. |

" I would buy the engine for the engine, not to save money on an oil cooler."
Its obviously not the cost of the oil cooler but getting one to work without having to cut the car for the engine or the cooler. |
