I tried searching, but didn't get much.
What is involved with fitting a 2.7 with CIS in a 914? I can figure out the plumbing and the electrical, but I believe that I had read long ago that it was a PITA to fit CIS without cutting anything or perhaps a mixture of different parts could be used or parts of the intake could be relocated in order to get it all to fit. I'd prefer to avoid cutting this 914 engine compartment since I'm trying to make this one appear mostly factory. Any advice or better yet pictures would be appreciated. I'd rather not go with carbs, since I believe that I'd need to swap cams and pistons in order to do it right. This one is only going to be a fun street car (I already have a dedicated track car) (All my conversion experience has been with 3.2s, but I have this body, and I have this engine...) Thanks in advance! |

You actually rotate the cis 180 degrees and rebolt down.. It is pretty straight forward..
Let me know if I can help.. Also note the naro mount drops the height of the engine approximately 3/4" and will NOT allow for a stock scavange line.. |

Do you know for a fact that it's possible to rotate the intake 180 degrees and have it fit or did you hear that second hand? I can try that on a stand and see if it all works before attempting to stuff it in the car. I will probably make my own mount and sheet metal again. It worked well with the 3.2s I did. P.S. I may want to talk to you about exhaust. |

It is hours away from me at a body shop and the engine is out so cant take new pics, but if you search my conversion all the pics are there. |

You have given me hope that it will fit. I suppose I need to go for it and see what I need to change in order to get it to fit. |

Had good pics and notes. Cant find it. Tried to use google as well...found lots of my transmission propaganda, but not my car. If you can find my threads from about 2004-2007 you will see good pics and info on what I did and fought with. I took out the rain tray and cut the engine bat release cable and tube out and make it pin down type. This gave me plenty of room. You unscrew the pressure manifold and simply rotate it and screw it back in. IIRC, 3 screws so can actually rotate less than 180, or more. I moved mine sideways, if I am not mistaken. Pics on home computer. Fuel pump plumbing is different. Need the fuel pump, very high pressure. I replaced all my hoses with clear, new hoses for like $12 from NAPA. I did find the thread mentioning that. Boil water and push on to nipples, hard (man, that reads wrong). |
