Begin drinking heavily now. That way it's not such a shock to the system when you start doing it because of the car. (IMG:style_emoticons/default/biggrin.gif)

Thanks Pete!
I would like to hear how you did your ignition and intakes. What did you do for the O2 sensor? What items did you have to modify on the sheet metal? Do you have photos? Can I use the flywheel from my 2.0 6? Jeff |

QUOTE how you did your ignition and intakes. I don't know QUOTE What did you do for the O2 sensor? You can weld a bung into your 914-6 head exchangers or muffler. QUOTE What items did you have to modify on the sheet metal? I don't know. My sheet metal is custom fabricated. QUOTE Do you have photos? I do of my 3.2. QUOTE Can I use the flywheel from my 2.0 6? I believe that you can, but the timing marks will be off (as far as I know). Supposedly the index on the flywheels changed over the years. You can move the timing mark(s) though. good luck. |

Huh?
I thought that last 914 you bought WAS a 6, no? Oh, maybe it wasn't a 3.0 though, huh? |

Hey Scott,
Yes it is currently a 6 and I am dropping in a 3.0 as soon as I can get all the info! John, Can I just put the flywheels together and transfer the marks? Thanks all, any info that will help me is greatly appreciated! Jeff |

John, Can I just put the flywheels together and transfer the marks? Thanks all, any info that will help me is greatly appreciated! Jeff You could. But what I would do is to install the desired flywheel and bring engine to TDC (pulley marks) and then mark your TDC on the flywheel and eliminate the original mark (so you don't confuse it with the real TDC mark). This way seems to be a more precise way of marking the flywheel instead of eyeballing it. (I'm not sure how you would precisely hold the two flywheels together to re-mark the early one). Good luck to you. The 3.0 is CIS if I recall.... I think there are some old threads about making a CIS setup work in a 914 engine bay. I have done 3.2's, but not 3.0's. |

You want to use crank trigger, but retain CIS? Thats an odd one. If you retain CIS, mught as well leave the dizzy alone. It will be FAR simpler and no diff in power.
Can't use the 2L /6 flywheel. <=2.7L used different # of flywheel bolts on the crank compared to >=3L motors. The ~76 Carrera3.0 still used the old 6(?) bolt crank, but I think its the only one that didn't fit the rule. |

I was told that I could add crank fire and eliminate the timing problem, a hard to get too dizzy. I have Webers but I would prefer to keep the CIS. If I can't add crank fire then I will just leave everything stock 3.0. Jeff |

What year is your 3.0 from?
later 81-83 have the lambda brain which you will have to mount, they also have the metal fuel lines. The earlier ones have the larger intakes though. I think kennedy has an adapter flywheel to use with the 901 clutch, this is probably the best route. sounds fun (IMG:style_emoticons/default/driving.gif) |

I've done a similar conversion using the CrankFire box and Webers, it really goes together quite easily. Just watch your timing light strobe and you'll see the difference between crankfire and a dizzy. Plus, it reaaly cleans up the engine compartment.
I would call Richard Clewitt for the latest, but it's a neat system. You can also go the BITZ racing route and do up an electronic fuel injection system using the stock CIS system parts with minor modifications. The elimination of the dizzy does really help you set the timing and no more points to change. |

no points on a 3L dizzy
If keeping the cis, I second keeping the dizzy. Also, put a pop off valve on it, if not there already. If yours is '80 - '83, ARP sells O2 bungs. Also, if 80 - 83, there is a grn-wht test lead on the harness that you can plug into your dwell meter to set mixture, which is nifty. Did the engine come with the fuel pump/accumulator/6pin cd ? good luck - get to work! |

I was told it was an 83 and it came with the fuel system, 6 pin cd, computer, tach and 02 sensor. It already has a popoff valve as well.
I will check for the green wire later. Anyone have contact info for Kennedy? I could also use photos of 3.0 set ups if anyone has them. Thanks all! Jeff |

If you have an 83 than chances are you have the later style case too which has the side oil drain and no sump plate.
http://www.kennedyeng.com/ is there web page which has a phone number Do you need photos of it setup in a 914 or just general phostos? YOu can check the engine number here : http://www.adelgigs.com/911scproductiondata.shtml |

QUOTE Did the engine come with the fuel pump/accumulator/6pin cd ? Isn't the acculmulator for hot starts? You may be able to delete/bypass this if you don't have it. |

The motor is a *64D2000*+ which is what I was told, an 83 SC.
I am looking for 914 set ups and any tips going forward. QUOTE Isn't the acculmulator for hot starts? You may be able to delete/bypass this if you don't have it. I have it but do I need it? Jeff |

I have a 3.0L from an 83 SC. I kept the stock CIS and Dizzy. Got an adapter plate and clutch assembly from Kennedy Engineering and used the flywheel from the 3.0 with my 901 tranny. Runs great.

Yes, I spoke with Kennedy this afternoon and they said I could buy the adaptor ring, clutch and TO Bearing for $525 new or I could have a flywheel made for $300 plus the clutch kit for $355 totaling $655. That does seem the cheepest and easiest. How hard is it to set the timing? What about the accumulator? Did you use it or leave it off? Jeff |
