which is also where i added the fuel filter, right before it feeds into the injection rails

We will definitely look at this the next time we get to work on it. Thank you again Clay @ClayPerrine and Andy @SirAndy for helping us out.

I tool the pressure line on top of the engine apart and rebuilt it with new hose. When I did, I flipped the center section so the fitting was on the side next to the battery tray. If you look close, you can see it in this picture.



It is between the two rear intake runners,and under the injector rail.

Is that a Gatorade economy catch can?

what flavor

"Misty Oil with a hint of Brackish Dew"

Just ordered the cylinder head temperature sensor; hope it arrives quickly. I can't believe I did not notice that before.

Yea.. you're gonna need that.

Yesterday, Greg, my brother and I went to the Diablo Region PCA Wash 'n Shine at the Danville Livery (Sycamore Valley Rd and San Ramon Valley Blvd). It was a terrific day with perfect weather. There were a whole lot of Porsches in attendance. Amazingly, only 2 993 cars attended, a '98 and a '96. We needed a '95 OBD 1 car.

Fortunately, Alex had reached out to me and said he had a '95 993 and lived in San Ramon. He was only 7 miles from the car show. Greg and I drove to his home and saw his absolutely stunning and pristine 993 Coupe with about 60K miles on it. We were able to take photos and look at harness routing. That will certainly help us get one step closer to getting the engine installed. Thank you very much Alex.

Here are some pictures:

I am guessing we don't need the heater fan blower sensor or the charcoal canister valve assembly? @sirandy where did you plumb the charcoal canister connections? Normally one goes to the shroud and one goes to the air cleaner. On the 993 it goes through a valve assembly that connects to the intake manifold.

You are going to need the charcoal canister solenoid to keep the DME from setting codes. And you can plumb that back into the 914 charcoal canister system.

The 914 charcoal canister system is a blow through system. The 993 charcoal canister is a suck through system. You hook the line for the charcoal canister that originally hooked to the fan shroud and hook it to the air cleaner Hook the other line to the 993 charcoal canster valve that connects to the intake.

@ClayPerrine & @Steve . What does the charcoal canister solenoid look like? I am thinking I do not have one.... But I do have the original charcoal canister in my trunk though. Just have to run new lines to it as it was terminated in the front fender when we had the 3.2 in the car.

I honestly don't remember ...

@cairo94507
He’s referring to this hose and solenoid. I will put mine back. Thanks Clay!

Cool; I may have that. We are back at it tomorrow, so I will look and see. Thanks guys.

75 cars have the charcoal canister in the engine compartment and run one hose from the tank versus two if you mount the charcoal canister on the gas tank. My charcoal canister fits perfect between the battery tray and the firewall. Just depends if you want a factory look. Did your car come with a charcoal Canister? I read the real sixes had a “T” that connected the tank overflow to the vapor hose out the bottom of the car.

@Steve Yes, my car came with a charcoal canister mounted on top of the gas tank.

This may help you:

Basically hook the diaphragm valve to the charcoal canister line that went to the air cleaner, and hook the other one to the 911 air cleaner. The reason for doing it this way is the charcoal canister has to have the correct airflow direction to work properly. Hooking it up like this makes sure the airflow is correct in the canister.

Yesterday we were able to make the "pipe" that will be the idle control valve hook-up. Made it out of 1" SS mandrel bends. Greg welded it and it is going to relocate the idle control valve down below the intake, near where the cruise control module once lived. We just wanted to get that off the top of the motor for aesthetics.

Then we pulled out the 993 harness that came with the engine, to connect the DME, engine harness and the car. After spending over 2 hours looking at wiring schematics for the '95 993 3.6, the only 2 connections that are correct are the knox sensors. We started looking up wiring colors and nothing matches the harness we have. In then end, we believe we do not have a 993 harness. We were able to identify a few plugs that are correctly colored for a 964. I contacted the seller (not Chris) and he said "that's the harness I got with the motor". He did say he would check his inventory of parts and see if he had another harness. Fingers crossed that he just gave me the wrong harness. Very frustrating as we had hoped to be able to get most of the wiring sorted yesterday.

I am also going to reach out to a custom harness maker and see what that would look like.

Anyway, if it was easy, everyone would do it. We shall get this sorted.

Hard to tell from the picture but make sure you still have enough room for the crank case venting hose that also needs to go down there.

The custom pipe looks really nice! I might steal that idea.

Thanks @clayperrine Is the diaphragm a 964 part? We just have a control solenoid on the motor. Where is the diaphragm at on a 1995 993?

The 993 uses a slightly different system. I don't think it is compatible with the 914 charcoal canister. Just get the 964 diaphragm valve and hook it up like a 964.

@SirAndy - When making the "pipe" we allowed for the crank case breather hose. . Nice looking out though.

@clayperrine is the part number 928-110-429-09-OEM ? Porsche Fuel Tank Breather Valve. It looks like the correct part.

Just bought the correct '95 993 3.6 harness; should have it in my hands by Tuesday. YAY!

I don't know. Mine came with the intake system I bought.

Clay

It looks correct based on my research. I ordered one from Pelican. Thanks for the help!!

@Steve Please send me a picture so I can see if I need one too.

@cairo94507 Here is a link to the part from Pelican. https://www.pelicanparts.com/More_Info/9281...amp;SVSVSI=0643

It's a 964 part, but it does make sense according to Clay and from what I have read. Clay says without it the DME will throw an error. It looks pretty simple to connect up.

The DME will throw an error if you don't hook up the solenoid valve. But it is very simple to hook up the rest of it and have the emissions evap system working. Plus it make your garage not smell of eau-de-petrol.

My cylinder head temperature sensor arrived. Hopefully my "new-to-me" 993 harness arrives tomorrow.

Yay!!! My chassis harness arrived; Wednesday we get to see what we can make of it.

Dissecting a wiring harness can be a daunting task.

We made some great progress on the wiring harness and the vacuum lines. What a difference the correct '95 3.6 harness makes! We started by connecting the MAF sensor and amazingly a lot of wires just kind of fell into place. We did lengthen the Idle Control Valve wires as we have moved that from on top of the engine to below the intake at the rear of the motor. The connectors we could not intuitively figure out we used the wiring diagram and sorted those.

The vacuum lines, and man, there is a lot of them, all made sense with a vacuum diagram. I think we have 2 vacuum lines that are still not connected but we know where they go.

We also routed the distributor "ozone" vent tube to what we felt was a good place.

I think in a couple weeks we should have it in the car.

Cylinder head temperature sensor. Don't worry, we routed it through the tin with a nice grommet to protect it.

What the heck is this and what does it do? @ClayPerrine @Steve

@Cairo94507 Unplug that goofy resistor. That’s part of the auxiliary heater fan
Otherwise, looking good!! Congrats!! Almost there!

Great. Thank you Steve; I appreciate the help.

Steve and Clay @Steve and @ClayPerrine - Thank you both so much for keeping us on the right track. We are getting closer and closer to being able to get the engine installed.

I just had the oil cooler shroud covered in Perlon (like the previous one was) and it came out great. I do not want to button that up until after we get her fired up and check for leaks

Just enjoying your journey!

Exactly what I was thinking!

Hey! Let's see some pics of that shroud!

@Tygaboy - Hi Chris- here you go:

I have to say, this shroud came out great. Thanks again to Chris for his mad fabrication skills and willingness to tackle this project.

Michael - That looks great! Thanks for the pics.

Yesterday Greg and I, (really Greg) got the steel fuel line installed that takes fuel from the passenger side, (where we located the fuel filter) to the drivers side where the fuel rail input is located on the 3.6. Greg secured the line with nice rubber insulated clamps to keep it safe and secure. Now we need fittings to complete the fuel lines where they connect to the engine and fuel filter.

Then we tackled the "Mickey Mouse ears" we got from Patrick Motorsports. If I am being honest, I was utterly disappointed with this product. This PMS part sits atop the engine fan shroud where it is very visible, and connects the heater air supply tubes to the heat exchangers to get heat into the car. As received, this was a horrible fit. Both of the heater connection ports were poorly positioned, (IMHO ) unless you wanted these heater tubes to look like some kind of wild tentacle abomination coming out the top of the engine. We decided to modify the right side (looking at the motor) to allow the hose to connect at a much lower angle to better fit the engine. The left side however, was far worse. That port was pointing almost straight up! All PMS had to do was rotate it 90 degrees and it would have been 100% better, allowing the heater tube to lay closer to the engine and look much better. Greg cut it off, rotated it, shortened it and welded it back on. Greg looked at the under side of this piece and you could see a good 3/8" of overlap from the mounting plate, obstructing the port; that was how it was received. This is designed to flow air- Greg "ported" both openings so they are smooth and unobstructed - it just looks right now- even though it will never be seen. This is more important, given the next change.

Then we had one more issue re the heat exchanger supply lines.... the hole through the engine tin is partially obstructed by the 3.6 design. Now our cars typically run 60mm heater tube. The 911 SC cars ran a 50mm heater tube and they also used a really nice reducer to go from 60mm to 50mm. We sourced some of those, (factory Porsche part) and bought 50mm hose. Now the tubes fit through the engine tin access holes with no problem. The added benefit is it also looks a whole lot nicer on the engine. We shot the Mickey Mouse ears black and put them on the engine and mocked up the lines- we both liked it and will call that done. Once everything is really dry we will permanently install the hoses and clamps.

Now don't get me wrong, I appreciate PMS making all these parts for the engine-swap crowd; I just wish in this case they would have spent an extra 10 minutes to look at it and make aesthetics a bigger part of the design calculus.

Awesome thinking outside the box on this continuous challenge. Looks much better. The Mickey Mouse ears reminds me more of Hell boy. I Installed mine, but covered them up for now and blocked the holes. I will initially be running 1 3/4” MSDS headers and maybe seat heaters. I was also thinking it might be better to run a stock 914-4 heater fan to run the heat exchangers instead of the ears.

I "see" Tusken Sand Raider in the micky mouse ears...

I've been watching but not commenting.

The work is exquisite and doesn't require my opinions.

NICE!

Looking good. Isn’t amazing how we never leave these cars alone. My car is currently sort of running off megasquirt. Last year it ran pretty decent on carbs but I can’t leave well enough alone

I have really enjoyed watching the "It takes a Village" progression of this project. Every little thing has been tidy. A beautiful job

@Steve - Yeah, we had another Steve who did not like the Mouse ears and suggested we run a 4-cylinder electric fan. I just did not want to add another component to the engine bay- I am trying to keep it uncluttered. I think with the modified "ears" we are going to be happy and it should function fine.
