After The Beer Run we hosted a few weekends ago, this happened. I was taking my friend JP to the airport. He had spent the weekend driving my 72 1.7 and was returning home to Vegas. We had a little time to kill so we stopped off at a coffee shop and he pulled up our local Craigslist to see if there was anything interesting. One of the 1st things he found was an add for a 914 with a V8. He thought it looked like something he may be interested in and the price seemed reasonable if it was half as good as it looked, so we called. There was no answer so I figured it was a fake add and I could start to expect random spam calls in the near future.
I took JP on to the airport and worked my way back to the shop to tuck my car in. Just as I was about to pull the car in, my phone rings. It's the seller from Craigslist and he still has the car. I call JP and he has just boarded the flight but is still very interested in the car. So I pull the car back out into the pouring rain and make my way up to Vancouver. The weather continues to worsen and as I am pulling into Vancouver, I get a call from my wife that they have just issued a tornado warning for the area (not a normal thing in this part of the country. ) This is a short video of what I found 914-8 https://gopro.com/v/PoOrJrOPGvB8a Attached thumbnail(s) |

I've done a lot of motor switches. This was my first with a Porsche, however. I always try to make my engine transplants look like the car came that way from the factory (as much as possible). This forum has been a huge help in that regard in all areas including wiring. All the wiring changes below are prior posts by others on the forum.
Here is my standard 3 wire GM/Delco alternator... (IMG:http://www.914world.com/bbs2/uploads_offsite/live.staticflickr.com-20876-1569521756.1.jpg) The wire indicated by the yellow arrow goes directly to the + terminal of the battery. The wire indicated by the green arrow loops back to the same terminal as the yellow arrow wire. This is the sensor wire to tell the regulator how much to charge depending on the battery condition and load. The wire indicated by the white arrow turns the "idiot light" on and off and goes to the relay panel in the engine compartment. Here's my relay panel... (IMG:http://www.914world.com/bbs2/uploads_offsite/live.staticflickr.com-20876-1569521621.1.jpg) The white star is the power relay. The yellow star is the fuel pump relay. Both of these need to be in place. The wire indicated by the white arrow goes to ground. This wire "fools" the system into thinking there is a stock ECU in place and allows you to hook up a low pressure fuel pump for the carb in the same spot and with the same wires as the stock high pressure fuel pump. The wire indicated by the orange arrow is the wire indicated by the white arrow from the alternator. It is the one that turns the idiot light on and off. It hooks to the terminal shown that the voltage regulator used to plug into (now no longer needed since the alternator is internally regulated). The wire indicated by the yellow arrow is attached to a switched, non fused, 12V terminal on the relay panel. I am running my electric choke from this terminal. Other than power to my fans on the radiator in the frunk, I believe these are the only wiring changes I had to make in order to install the V8. (well, there is the rev limiter and the TachAdapt, but those are easy ones) (IMG:http://www.914world.com/bbs2/uploads_offsite/live.staticflickr.com-20876-1569521622.2.jpg) |

Delco 10si alternator is easy to wire if you understand them. same system I used putting that alternator on my tractor, an antique road grader, etc. It's also available as a one wire alternator by changing the internal voltage regulator. Any starter/alternator shop will set you up either way and sell you that nice GM plug to work with. |

love the engine bay pic (IMG:style_emoticons/default/smile.gif) especially the iron manifold and cool distributor.
why the spacer under the carb? (IMG:http://www.914world.com/bbs2/uploads_offsite/live.staticflickr.com-20876-1569521622.2.jpg) |

I am using it because it fits without cutting the front of the rear trunk like you have to do with any other distributor I know of. The wedge spacer under the carb is to get the right angle on the carb so the floats can be set correctly. The engine sits flatter than it did in the front engine car it came out of. |

[/quote] I love that. I would like to repair the trunk and clean up the msd too. [/quote] I've seen some nice "dog houses" that cover the dizzy and seal off the rear trunk, and designed so the targa top will still go where it is supposed to go (when the sun comes out unexpectedly here in the PNW (IMG:style_emoticons/default/biggrin.gif) ). It would also be great to mount your MSD coil and control box so that they don't interfere with targa top storage and the stock place for your jack. I would think both could go in the engine compartment perhaps on the engine side of the rear trunk panel. That's where I mounted my coil. The downside would be that you may have to remove the engine/trans to do it and they might be difficult to service if necessary. What is the hole for on the right side of the front wall of the trunk? Here's mine... (IMG:http://www.914world.com/bbs2/uploads_offsite/live.staticflickr.com-20876-1570910255.1.jpg) |
