Hello,
My son and I have a 1975 Porsche 914 1.8l. Has the same stock fuel injection. Been sitting in the garage for years, but want to revive it. So far, took the gas tank out, getting professionally cleaned and sealed, all the rubber hoses are shot, but the 2 plastic fuel lines appear to be good. Need advice on just about everything, but engine issues first. 1. Removing all the 1975 smog items. Not sure what exactly what smog items to take off and and what should be only be remaining to run the fuel injection. Step by step instructions would be good. 2. Seals and gaskets to replace. 3. Pulled off the old heat exchangers and old Ansa exhaust, to replace with a header and muffler. 4. Air cleaner improvements? 5. Performance upgrades. Suggestions welcome ! |

Although the plastic lines seems fine, I would replace them with stainless steel lines. Tangerine racing sells them and a local guy from la also (sorry I forgot his name). Most seals and rubbers that I replaced are from 914rubber.com There are plenty of folks from so cal that always happy to lend their hands but will have to wait for that until we get rid of this cov19. And a lot of helpful folks here in the 914world. Congrats! P.S. We love pictures (IMG:style_emoticons/default/beerchug.gif) |

You may want to rethink the replacement of your heat exchangers. It does get cold in OC.
Let’s brake it down what putting on headers and losing your HE will give you. PROs.... maybe your going to gain a few HP out of a older crap 1.8 engine that’s probably giving you 65-70 RWHP. CONs.... You just spent a lot of money for a few HP You will get cold and driving without a defroster sucks Car will be louder. Which in my opinion is stupid if you don’t have the HP to back it up Replace your fuel lines, get your car to be 100% mechanically safe. Listen to your local OC 914 brothers, they are some of the most knowledgeable 914 peeps I have met and read everything in the Lapuwali Classic Thread Forum. |

Is it a California 914? If so, there is more smog than 49 state. Keep the parts as someone with a ‘76 might need them to pass the smog test. You’ll need to seal the heads after removing the pump. I’ve heard it’s NPT but not sure. Other than that, it’s not much different than the 49 state cars. Your exhaust will eliminate the CAT.

Instead of headers and exhaust, why not backdate to older heat exchange system? They will flow better, less weight and keep you heat too.
[insert shameless promotion here] I have a 73 1.7 heat exchanger with most of heat tubes (I think) for cheap. Just need heat exchange support and muffler. just something to ponder. |

Hello, yes it is a CA 1975 Porsche 914, 1.8l I will keep the smog stuff that is still good. Now I am looking for an exact direction of what exactly to pull off, and what to keep on a no smog 49 state 1.8l car. Pictures. |

I think I may need a list of what should be gone with no smog and what it looks like, and what the 1.8l should look like de-smogged. |

I will keep the parts. What is the best way to "seal the heads" ? So what are some of the best exhaust systems ? Need help on making a 49 state car. Thanks.. |
