Thank you (IMG:style_emoticons/default/beerchug.gif) I am a little concerned that the water pump and of course the fans on the radiator are electric. With the alternator just hanging down there with no splash guard incase of weather. Any suggestions? |

I've never been into V8 swaps, maybe because most of those I've seen has been paired with questionable 80's body modifications. BUT THIS ! Oh hell Yes ! (IMG:style_emoticons/default/aktion035.gif)

QUOTE(Matty900 @ Sep 24 2019, 01:42 AM) Thanks guys for all of the help. I am thinking that the battery needs to go back to the correct location too. It could get interesting because he put an electric heater box in that location. So I will probably relocate that to below the relay board. Matt, Looking at the pic it looks like it has water running through that box? If so, please take lots of pics if you relocate it to give the rest of us ideas on how that was set up! |

I will document the move of the heater box when the time comes. (IMG:style_emoticons/default/type.gif)
Gas stations- yes it does like to visit them. (IMG:style_emoticons/default/driving.gif) So I am looking at the wiring diagram of the relay board and where he hooked up the sweet "connection" with his roach clip (IMG:style_emoticons/default/blink.gif) And I am trying to figure out if I can put that in the plug on the board. If so, would it be on the 97 pin or the 9 pin? Attached thumbnail(s)

What is that roach clip/red wire powering?

You squiggled the wrong side of the fuse. It's switched 12v and it should turn 'on' the alt >> charges when turning. That circuit turns on the relays.

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. |

Awesome guys (IMG:style_emoticons/default/beerchug.gif) Thank you so much. This is what I was looking for. I won't be able to work on it until next week but I am sure that I will run into more questions with this project.
Looking forward to putting in some of our new solid State relays. Once Mark is done with them, I will get you guys some. (IMG:style_emoticons/default/piratenanner.gif) Attached thumbnail(s)

So I took the car out for a few fall photos today and I have a pretty good leak in the Radiator. It has already been repaired at least once. Looking for recommendations. Repair it again or just replace it. If so, what do you recommend for a replacement radiator? (IMG:style_emoticons/default/confused24.gif)

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) |

Matt if your radiator is leaking I would think about replacing it with one from Rengade.
I think it’s from Ron Davis. You can buy directly from him. Craig at V8914 |
