After nearly 20 years without a 914, I finally bought a daily driver (IMG:style_emoticons/default/driving.gif)
It is a California spec '75 2.0 with original FI. I plan on pulling all the smog equipment as well as replacing the heat exchangers and muffler with SS exchangers and a Bursch exhaust. Just wondering if there is anything that will need to be plugged, rerouted, etc with these changes. Thanks! |

Some people just pinch off and braze the ports at the head. I have recently seen an ad in the back of Excellence or Pano for a threaded block off. I think they might be NPT but not sure of the size. Truthfully though, biggest bang for the buck is to backdate that exhaust system. |

thanks for the quick reply.
I think this weekend I will start by backdating the exhaust system as you suggested. The parts I have are from a '73 2.0. |

I changed my exhaust to SSI's and a Triad dual outlet. That was a HUGE improvement over stock. The engine ran smoother and cooler. It was the best money I spent before a 2056 kit from Jake.
