5k: 2.7L Flat-6 Swap In Process: 1975 Porsche 914

The Porsche 914 was originally built as a joint venture between VW & Porsche, designed to be a range topping Volkswagen and low-end Porsche.  However, according to internet legend, the Porsche executives decided at the last minute that they didn't want the competition from the VW version eating away at their profits and as a result was only sold as a Porsche. It is an unsung hero of the automotive world - financially successful, does a great job, contributed lots to the automotive scene...but overshadowed by a famous headliner- the 911.  However, if you remove the Beetle-descended flat-4 from the middle and replace it with a sweet sounding flat-6...things start to look much better.  Find this 1975 Porsche 914 currently bidding for $6,350 in Eugene, OR via eBay with 2 days to go.

It is never a good thing to see a car on jack stands in a seller's advertisement...well...I guess it is better than seeing a car sitting on 4 flat tires in the weeds.  It also shows a certain level of honesty (laziness?) from the seller since taking the car off the jackstands would be a 10 minute affair and result in considerably more money at an auction.

The original flat-4 was replaced with this 2.7 liter flat-6 from a 1977 Porsche 911S.  The 911 engine is rated at 165 horsepower and will be a considerable performance bump for the lightweight mid-engine 914 chassis.

What sort of snake pit did we just stumble into?  The few pictures of the interior show some free conductors that need sorting.  However, if you carefully read  the listing you will find that the seller says that a new owner will need to complete the engine swap.  Budget accordingly.

  2. It's a 1975, Californians...

    I don't know my Porch pancake-six history very well, how the 2.7 compares to a later 3.0 or even much later motors.

    I see a lot of hardware in those pictures, though, that looks like Bosch K-Jetronic CIS, or continuous-flow mechanical fuel injection. K-Jet is a black art, one that I once practiced in my Saab days, but today I wouldn't wish on my worst enemy (well, not true, I *would* wish it on my worst enemy, but not much of anyone else.)

    If you bought something like this, remove the K-Jet stuff, wave your hand over a Bible and mumble a few words, then tip the plank and let it slide overboard into your eBay listings.

    Someone out there may want it, but the rest of the world needs an aftermarket or DIY electronic setup.

    Do you know that the early Euro-market Saab turbos used a 6cyl fuel meter with two of the ports plugged? Yeah I did that to my '81 900. Did it help? Yeah, a little bit, after a LOT of component swapping. And these days...well...CIS was based on putting a circular flap in the airflow that the engine had to suck open against 80+ psi of fuel system pressure, and the linear movement of the plate controlled how much fuel went to the injectors.

    Get rid of the K-Jet, find an aftermarket or DIY electronic setup, you'll gain 20+ HP just from getting rid of the fuel/air meter box.

  3. Yeah, why'd they pick a 1975 rubber bumper car for this build?

    1. For California purposes all that matters is that it is pre 1976.

      The bumpers can be purged, but for a later car the California smog Gestapo will be a boil on your backside forever.

  4. This thing looks like it might have some potential for fun at a reasonable price.

    However, I am not at all familiar with the 914 details. Can you remove the rear trunk lid and the trunk liner (like a lotus Europa) to get at the mechanical bits easily, or do you have to go at it from underneath?

  5. Yeah it has the rubber bumpers, but the rubber bumpers come with windows that roll up more reliably, a real passenger seat, doors that are considerably safer, and much better seat belts.

    I love my 1970 914/6 but as transportation, the latter cars are better, not nearly as good as say my beater Subaru

    This car looks like it was originally lime green, why someone would repainted it that ugly maroon is hard to figure.

    It seems like a pretty good deal just in terms of parts for a hotrod 914/6
