I am not looking for a V8 car specifically, but I do want to own a 914 with a nice modern transmission swap. Why wouldn't you want the orange color it is now! (IMG:style_emoticons/default/drooley.gif)

If it was built by Bob, I am sure it will be a great driver. Add a fuel injection kit to the 383 along with the Boxster trans will make for a reliable hotrod.




I said the same thing about the color. Not much better than a fresh coat of Signal Orange. It'll be nice car that you can drive anywhere.

Update...working on the "heater core in the fresh air box". First I had to take the wiper assembly out to lube it and change the rubber mounting bushings. Dang that thing is not fun to reinstall!

Here is the modified airbox.

FYI the STOCK mid-90's mustang heater core is a little too thick to fit inside the fresh air box. I had to modify mine a bit. I'd go for the thinner aftermarket one if you're going to do this.

I'll have a bleeder valve on the higher line and a Rabbit open/close valve on the lower intake line.

So if you do this you will be eliminating the tube that comes up from the passenger compartment and connects to the heat/fresh air distribution system up front through this:

You can seal them up with these 2" rubber plugs from the plumbing aisle at Home Depot:

You also want to lock the flapper in the up position to keep any heat/fresh air from escaping or coming out the wrong area.

Permanently lock this

Now...couple of quick questions...

Does anyone know how the wires that connect to the fresh air box go back in to the connector they go in?

Attached Image

Could someone look at their 914 and see which way their lower heater outlets under the dash are pointed? Does the wider opening point towards the middle of the car or towards the door?

I just keep looking at this thing...the simplicity...why did I wait so long?

Every wire is imprinted with the function.

The EG33 ECU itself has 76 wires. There are also ~4 more that connect to other things. This harness has 36 wires, many of which won't even be used.

BTW also could someone PLEASE look at the plug that is connected to his/her fresh air fan up front and tell me which wire goes in which slot here? It's the 4 connector power source for the fan. Thanks!

I have LOTS of updates but need to prove they work before posting them. Will document the MS3 install as well.

Hard to get to. Even after I removed the expansion chamber from the gas tank. Looks like I used Andy's camera. (IMG:style_emoticons/default/av-943.gif)

Perfect! Thank you Kent! Now I can test my heater. Have to finish the timing belt job on my wife's Volvo then I'm 100% finishing the 914 refresh.

Totally replaces it. Also eliminates many of the unneeded stuff like the EGR, complicated fuel pump/fuel delivery system, etc.

Very cool! So is there a MegaSquirt map already available for the EG33? What are you doing with that old harness? (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/idea.gif)

Hi George,

There are maps on the msextra site. I have a crap-ton of wiring I can give you when I'm done. I'll also have an extra ECU I can pass on.

I picked up a used MS3 with the expansion boards and ignition modules needed to run the advanced came on the EZ36 for 750$ earlier this year.

I love what you did here Chris! I'm going to be working something similar in the next month or two, but I may try to make a custom core to size. Love seeing the ingenuity!

Yes you definitely want one that fits in the box, preferably one that exits out the side. In a stock 914 everything in that area fits PERFECTLY without a mm to spare although it doesn't look that way. Mine was a PAIN IN THE ARSE to install because it's so close to the fuel tank filler. I think an aftermarket Mustang one that is thinner might work. You could trim off the circular piece above the fan right down to the box (which is necessary for any heater core) and then take it to an auto parts store and have them find one for you.

Ah....hindsight...at least it's useful for others... (IMG:style_emoticons/default/biggrin.gif)

So "how's it going" with the MS3X install? I think it's best summed up by the first 43 seconds of this clip.

Bob's been helping me a lot but the MS forum has been poor. I think I might post some stuff here in case anyone has other ideas...

(IMG:style_emoticons/default/av-943.gif) (IMG:style_emoticons/default/lol-2.gif) (IMG:style_emoticons/default/laugh.gif) Remember the post card with the Cow standing on her own utter which read "So you think you've got problems!"? Well don't feel alone my friend. I damned near took mine out back and shot it this last weekend. I won't pollute your thread with my problems though. (IMG:style_emoticons/default/lol-2.gif) But, as with every problem there lies an answer within and I finally found mine. Looks like we may be posting in tandem again.
