Then slide the boot on (tight!).

Crimp the connector.

First wire done.

In place. I need to get some plug wire holders.

THey make a good clean cut. But you can't use them too much,they get dull. Nice collection. Road or MTB your preference?

I prefer dirt, but variety is nice. And hoping for some snow soon.

I made up the other 3 plug wires today, and plugged everything together. This layout should work, but I want to add a couple of wire holders.

Next up: Fuel lines and components.

This is the pressure regulator, and the Dub Shop bracket. More cool stuff!

I don't need the auxiliary ports, so installed the plugs, with a bit of #3 sealant on the threads.

And then the barbed fittings for input (side) and return (bottom). These have O-rings and don't need any sealant.

I will mount this on the bracket for the original MPS.

Drilled some new holes, and mounted the bracket.

And then the regulator.

Now time for the fuel lines, starting with new grommets for the side shelf.

Grommets in place.

First, I tried the short hard-lines upside-down, since I moved the pump to the front. Not really a good fit.

The "correct" way looks better.

Once upon a time, I had a label on the supply line coming out of the tunnel, but that got lost. So I tried running the fuel pump, using a jumper between the number III tab on the FI system plug on the relay board and ground (ignition on).

That worked, with a subtle but distinct air pressure build up in the supply line coming from the pump.

I also started to mock up the lines on the engine, connecting supply to left injector rail, left rail to right rail, and right rail to pressure regulator.

Running fuel lines in the engine compartment, to connect the hard lines in the tunnel with those through the shelf.

I decided to double-clamp all the connections--probably overkill, but who wants fuel loose in the engine compartment?

I also used some plastic tubing to protect the lines from the retaining clamp edges.

At the top side, connecting the pressure regulator with the return line.

Last bit today: sealing the fittings in the injector rails with some #3, careful not to get any on the internal ends.

Fittings in place, both sides.

Bob, this is such inspirational work. Thanks for sharing. It's getting so close now, I can almost hear that engine purrrring.

Thanks. I suppose I can get a soundtrack file if I have to.

I have Dub Shop injection and spark kit on my 912 (modified original 616 motor) and it's top notch. Mario is a great guy, too.

Loving your work. Great thread!

I'm slowly going through this thread from the start and marveling at the work you've done.
How did I miss this ? Page by page it gets better and better.
I feel I should apologize for failing to compliment you for all the varied, complicated and time consuming jobs you've done....with no complaint or regret.
Unbelievable !
Bob, you've set the bar.
Well done.

∆This.

Very nice, and cool car. I do like 912s!

Thanks. The timing of this project has been good for me, in semi-retirement and with all the COVID stuff. And having the funds to indulge my ideas.

As for complaining, check with my wife.

Thanks, Ian. Your videos really set the standard, and have been both helpful and inspirational at key times.

Any guess what this place is? Hint: not far from London bridge.

Here it is from the back.

Answer: California Motor Sports, in Lake Havasu City, Arizona. Home of the Porsche transaxle rebuild. Mine needed a bunch of replacement parts, including a new intermediate plate. They CNC machine these onsite.

Here's my like-new box, strapped into my son's GTI for the trip to Tucson. Next week I will get it home, and get on with installation.

Awesome!!!! I sure wish Arizona was a bit closer for me...

Forgot to include a picture of the bridge.

Arrived home with the transaxle. I unpacked some of the things in the car, but will have to finish the job tomorrow. I want to get the engine and trans in the car before my son comes to visit at the end of December. Time to get busy.

OK, getting back to work.

My first chore was to get the car off the wheeled dolly. I figure that the total weight, and balance, with the drive train installed might be too much.

Two floor jacks under the back, lifting on the engine mount brackets.

And my engine jack, aka motorcycle lift, on the suspension cross member in front.

And then down onto my trusty Esco jack stands. I don't expect the car to be on wheels again until its ready for the road.

Time to get as much finished on the engine, since the access is easier now.

First, new spark plugs.

Plugs checked and gapped, and installed. I took the intakes off to remove the paper towels I had blocking the head ports (and then install the intakes with gaskets).

I also got rubber boots for the plug connectors.

Installed. The holes for the rear plugs are near-perpendicular to the plug axis, so the boots sit even. The forward holes are more oblique, so the boots sit less even.

Fuel lines run and clamped, and the throttle bodies bolted on. I then ran all the cables for the EFI and ignition components. I need to lay out some brackets and retainers.

Can't wait to see this in the car and running.
