Like the title says, what year 911 flywheel do I need so my 2.4 6 will bolt up to my 901?

You will need the one that is for a 2.0 6 motor. Like an early 911 or a real 914-6 would have.
Gonna get that motor going? |

QUOTE(jasons @ Mar 21 2012, 01:03 PM)  Gonna get that motor going? Trying. Picking up parts for it now. Have the carbs, manifolds and dizzy but still need the alt, shroud, fan and flywheel. After I get all the pieces I'll tear it apart and send it out for machining. Hopefully I can get by with just rings and honing. If not I'll have to slam on the brakes until I have the funds for new p/c's. |

You can use a stock 914-6 flywheel. But there's a difference in the timing marks and TDC will be off, due to the difference in the crank of the 2.4. I took back a "bad" new flywheel years ago, that was used on a 2.4, and found out there's a difference.

It's a six bolt flywheel that bolts up to 2.7 liter engines and smaller.

QUOTE(Steve @ Mar 21 2012, 02:23 PM) It's a six bolt flywheel that bolts up to 2.7 liter engines and smaller. but the 915 flywheel also is a 6 bolt flywheel that bolts up to 2.7 and smaller engines.... so it has to be a flywheel for a 2.0 motor |

The 914 uses a 215mm clutch, so the last year a 911 used a
215mm clutch was 1969 (901 flywheel). 1970 was the first year of the 225mm clutch (915 flywheel?). |

I meant to say you can use the 911 2.0 six bolt flywheel on 2.7 liter engines and smaller. Starting with the 2.2 motors they went with a 225mm pull type clutch. The 2.0 flywheel works on engines up to 2.7 liters and allows a stock push type clutch for use with the 901 trans.

You can also use a "915" flywheel (225mm) IF you use a 70 or 71 911 clutch disk and the pull type arm from a 70 or 71 911. It will also involve moving the pivot point inside the 901 bell housing to accommodate the different length of the arm.
The advantages are that you can use a straight cable with no pulley on the transmission to work the clutch. And don't anyone say this doesn't work, as I ran it on my car for 2 years. |

Or you can just swap your trans guts and rear cover with a 70 or 71 911 trans. I drove one with a 3.0 and I thought the clutch feel was night and day better than the KEP Stage 2, I am running with my 3.2. |
