Wanted to start a build thread for my na suby conversion. The car is my newly acquired '73 2.0L fi. It is very clean, appearance group, 2nd owner, 88K. I currently use it as my daily driver.

I want to do a suby conversion because I believe the overall package will have the performance, drivability, and dependability I'm looking for.

EDIT: I've changed motor selection slightly and am also taking a bigger plunge by going with a suby trans, see Post #49.

Dean,

How did you handle the ignitors for the coils? I know MS has built in ignitors. But some of the other EMC's do not.

Not familiar with the stinger....

Also, isn't there some kind of unwritten rule, that it's not really running until there is a youtube video of it.... (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/poke.gif)

Still waiting for start on my conversion. Too many projects and my job keeps getting in the way...

-- brett

Hey Brett, it must be built in with stinger, I didn't have to do anything except plug in the engine harness they made for me and connect a few wires for the ecu power, fuel pump, etc. So easy even I could do it. (IMG:style_emoticons/default/shades.gif)
You'll just have to take my word for it, it's running... ok the video documentary will be revealed soon.



Thanks for the info. I have a Link ECU and it states in the docs that it can't drive the coils directly. I will have to continue to research. I do have a MS II i can use also... We'll see which direction I go. (IMG:style_emoticons/default/smile.gif)

Looking forward to seeing the video.

budman5201 has been using Link with his suby projects. He's been a great help to me in the past. You might want to send him a pm.

Here's a short clip of my son and I heading down to meet the guys for our local 914 meet this evening. Not much but lets you hear some of the exhaust note. I'm really happy with the exhaust sound, very deep and zero rasp. You'll see me using the gps for a speedometer for now, never a shortage of projects.

Boy that sure is good motivation. Nice job. Most of my projects really never end. When the dust settles you can study up on doing your own programming with a laptop. I wanted to have different maps one for e85 and a couple more for cheap gas and good gas. Someone is going to come up with a device thats checks fuel quality in the tank as you are using it and adjust the tune accordingly. The suby ecu sorta does that but the range is pretty narrow for peak performance. The old tt ej2oh I have would not let the turbos boost if the fuel quality was not good. The relearn part of the suby ecu is really tricky to tune with but it is very sophisticated. It watches even the fuel temp in the tank I think I remember reading.

Great video, I guess the camera was mounted on a hat? utube video and music is something that is out of my spectrum of shadetree. Thats both of my son's relm.

Great video...love these kind of "in the driver seat" experiences! The motor was music enough...could left out the other stuff.

Just curious...since I've never been in a suby 914, what kind of ball park rear wheel hp and torque are you running at this point? Estimate?

Put up another video without music...I would love to hear the just the motor and how the tranny is responding.

Great video! Loved it. And always liked that color. (IMG:style_emoticons/default/smile.gif) As well as that sound. I will have to go back in the thread and see the exhaust that you used.

Thanks Charlie, the camera is a ContourHD helmet cam. I made a head band setup I can wear. It's a fantastic little camera.

Thanks, so fun to be on the road again. Haven't been on the dyno yet, so not certain what I'm getting at the wheels. Should be close to 220chp and 200ft/lb at the crank. Whatever it is, it feels like a fantastic balance in this car.

Here's a vid with no background music, hey it was old school Bad Company, goes good with anything (IMG:style_emoticons/default/beer.gif) I know what you mean though, can be distracting.

You'll hear a whine in the gears when in low gears or backing off the throttle in any gear. I'm suspecting its coming from the differential. Anyway I'm not sure if it is just to be expected with this older trans or if its a sign of needing a rebuild. Made a post over on nasioc for some advice. If anyone here has some ideas about the noise I'd love to hear them.

Thanks Brett. I don't have much on my exhaust in the build thread yet. Here's a couple of pics. I'm using an OBX EL header which give the suby motor a smooth sound rather than the traditional suby rumble. It also gives me 10-15 more whp which is a big deal for an n/a build. I have a 14" resonator off the header to kill any deceleration rasp (which you can see a little of in the first pic) and then an 18" magnaflow muffler. It's a really nice sound, almost silent at idle and sings pretty when opened up.

Looks great! This is close to just what I want. Although depending on getting the adapter plate for the 901 tranny. Along with the suby adapter motor mounts. I know this guy who is dying to give me a great deal on them (IMG:style_emoticons/default/KMA.gif) . Just waiting to hear back from him on it. LOL

Thanks for the motivation posts!!!

I would be interested in your front modified valance when you go for a GT flared version (IMG:style_emoticons/default/beer.gif)

Awesome job!

Yep she's the best. She made sure to let me know that she would only go for a ride when it had a muffler, and when it was "glitch" free. I said "honey it will never be glitch free, it's a 914. But it does have a muffler now, so lets go for a ride".

Thanks Nate. Glad I could add some motivation, your build definitely motivated me when I needed it. It really is worth it all to get 'er done. Can't wait to see you get your car finished up. Got any updates for us?

Man...that is awesome!

I can't wait to get mine running. I got a date with the dyno in 2 weeks.

I say we try to get a group site at Pine Flats Campground this summer and have a long Porsche weekend. About 1/2 way for the NW crew.

Love the build. Im looking forward to starting mine.


Have you had any Knocking running the outfront computer ? I ran the same set up in my vanagon and had lots of knocking up over the pass. I had to go back to the stock ecu.

Yup. Great site. We can be river rats and rent a bunch of rafts.

No knocking at all, sewing machine smooth so far. Did you talk with the guys at outfront about it? They have top notch support.
