Another 914-6 GT Tribute Project Options

[Tom1394racing]

Hi Tom,
@Tom1394racing My high torque started is installed with he terminals on top like you have. It fits and the terminals can be accessed. (IMG:style_emoticons/default/beerchug.gif)

Thanks

I appreciate how you guys keep me out of trouble.

Hey Tom
Your project is coming along beautifully.
See pics of my lower ignition wire routing.
The grommits are 993 or 996 OEM
I'm away at the moment so can't provide the part #
Also, I used full size lower spark plugs and found the only plug wrench that would
work was the one included in '69-'73 OEM tool kits.
I also used 12 point cyl. head nuts for additional clearance.
The lower valve covers are milleded 996 items with the rubber perimeter seals.

Have you considered adding the spark plug retainers on the bottom plugs? I use them on my car and consider them cheap insurance and peace of mind.

Thanks Bill....I have a set ready to go.

Last finishing touches on the engine build.

I installed the twin plug wire set from Patrick Motorsports. I had planned to build my own set, but I found that I did not have any good Beru plug connectors remaining in my stash. The price on the Patrick set was considerably less that if I had purchased new connectors and bulk wire. I tried to follow the wire management for the plug wires and engine harness used on the factory GT motors as close as possible.

I also installed the new PMO 46 card kit and linkages and filled the gearbox with Swepco 201.

I plan to install the external Mocal T-stat, the MSD CD boxes, coils and fuel lines to the carbs before doing the engine install. I also need to install the fuel tank and fuel pumps up front before the engine goes in.

I'll have to sort out all the electrical connections between the engine, the chassis harness and the MSD system before the engine install. I expect this will require some modifications to the engine and chassis harness connections as well as the creation of some new wiring harness. Anyone who has already been down this path is welcome to make some suggestions to point me in the right direction.

It has been a few weeks since my last update. With the engine completed, I have been focused on getting the chassis ready for the engine installation. This includes the fuel delivery system, the engine oil cooling system and the engine electricals. My plan is to get these completed and installed before mating the engine to the chassis.

First up I decided to focus on the fuel delivery system. In the spirit of the GT project, I plan to use (2) early Bosch carb pumps installed in the front trunk. I plan to use a recirculating system along with a PMO pressure regulator and 46 mm PMO carbs on the engine. I will use (2) in-line Mahle fuel filters in front of each carb and a standard plastic filter at the fuel pump discharge. My plan is to install the engine, complete the fuel line connections, run the pump through the system, check for leaks and set the fuel pressure.

Before engine installation, I plan to complete the oil cooling system and the twin MSD/twin coil electricals.

Am I on the right track with this sequence?

Looks good to me and 2 fuel pumps that seems like overkill but looks great

Hi Ben

Many of the factory GT's had the dual fuel pumps. I was told the second pump was for redundancy in case the primary pump failed. The driver had a switch to engage the second pump. For me, the coolness factor was too much to resist even though it makes the setup more complicated and susceptible to leaks. In my case, the lower pump is a dummy with the ports and connections sealed up. The upper pump will be supplying all the fuel.

I saw the two pumps and thought the same.

Every time I've seen someone using two pumps (at the same time) they haven't worked like the owner wanted.

Pumps seem to fight against each other, and one always wins.

Your installation is the first use of a "dummy" for appearance I've seen!

Now, if you're really looking for "period correct" shouldn't the fuel hose have a cloth braided outer covering?

Your car and the work you have done to it is World Class IMO!

Everything is too perfect to use!

Thanks for the compliments. I will drive and enjoy this car once it is done.

I’m actually planning to cover the entire pump area with a protective grate like this GT rally car.

I installed the fuel tank with the GT style filler and the sending unit today. Checked for kinks at the bottom of the tank before leveling and installing the retaining strap.

Looking good there Tom.. Are you planning on installing the air box??
If so that fuel tank needs to come back out.

Hi Luke

Thanks for your feedback.

The exterior of the car still needs final body work and paint. My plan is to install the engine and get the car running before it goes back to Auto Associates for the finishing touches. Since they will be painting the front cowl area, Kenny and I decided not to install the airbox until after the final paint to avoid overspray in the top of the airbox. I know it will be easier to install the airbox with tank out of the car and I will drain and remove it if necessary.

Finishing up the fuel delivery system. I installed the PMO pressure regulator in what I think will be a good location for easy unimpeded delivery to the carbs. (2) in-line Mahle filters will go between the regulator outputs and the carb inputs.

One issue I am having here is that the fuel delivery line is 10 mm ID and the input line on the regulator is for an 8 mm line. I tried locating a new fitting for the regulator inlet with a 10 mm barb but I am having trouble determining the male thread type on the inlet to the regulator. I need a fitting with a 10 mm barb with a male thread to fit the regulator. The dimensions of the original 8 mm barb fitting are shown here. The inside thread diameter is about 10.9 mm and the outside diameter is about 11.9 mm. Anyone know what type of fitting this is and where I might find one with a 10 mm barb?

[BillJ]

I can't answer your question but not sure I love where you mounted that. Might be a little challenging to read that gauge once everything is in? Most place it between the carbs centered on the engine as I have seen it done. Just a thought. Looking forward to this piece of art completing

[Tom1394racing]

To circle back on the fuel pressure regulator.... The fitting was an M12X1.25 thread. I finally found a 10 mm barb X M12/1,25 fitting on Amazon. I also reinstalled the gauge to make it easier to read.

[Tom1394racing]

While waiting for the fuel fitting, I started test fitting the T-stat and connections to the tank, cooler and engine.

Hey Tom
What I did.
Not the ideal orientation of the gauge.
Two 356 bango fittings with seals pointed at each carb. Hollow bolts will be safety
wired.
Starter button incorporated.

Hi Rory...Thanks for your suggestion. I thought about that location. That's the spot I've used on my 911 with PMO's and the spot most commonly used on 911's with carbs. However, I like to use two in-line filters between the pressure regulator and the carbs. My experience is that the PMO's are very susceptible to idle jet plugging and that the in-line filters minimize this problem. It seemed to me that placing the regulator on the back bulkhead wall of the 914 would not leave enough room for the filters. I am going to try the side wall location and see how that plumbing works out once I get the engine installed. I'll move it if need be.

[flat4guy]

I was thinking of the exact same thing....forgot, just did that. You are going to have so much fun, post lots of pictures often. Best, Mark

@mlindner Nice orange car.
