 Is anyone still enlarging the diameter of our throttle bodies, Wouldn't it be nice to add a bit of power with a little more air?? |

I believe @JamesM is running the Vanagon TB and plenum. I'd be interested in what's required to make that work. I can't find a good pic of one of those plenums, as I'd like to see what the vacuum outlet/port selection is like.
I think this is is rig. Very clean setup. But I can already see I'd probably have wiring harness issues with the way it's oriented. (IMG:http://www.914world.com/bbs2/uploads/post-5834-1576449659_thumb.jpg) |

(IMG:http://www.914world.com/bbs2/uploads/post-5834-1576449659_thumb.jpg) Throttle body is 2.1 vanagon, the plenum and runners though are 74 1.8 parts. Only modification made was using a tailpipe expander to open up the plenum to match the 50mm vanagon TB, and swapping the throttle arm from a 1.8 throttle body over to the vanagon throttle body for proper throttle cable orientation. Using the Vanagon plenum is a bit more complicated as no 914 intake runners are a direct match to it. |

Thanks! yeah on a 2056, I dont have the specifics as I didnt build it but its far from stock. AMC 1.8 heads with oversized SS valves, port work, and custom chambers by EMW. EMW cam of some sort. Motor really come alive 3700+ rpm Going to be swapping it again for the 52mm throttle body over the winter is its still wanting more air. |
