Was the 914 meet at Niklas Ekström home near Malmo?
He has some nice rolling stock.

That's correct, he's got a nice little aircooled and watercooled fleet. (IMG:style_emoticons/default/wub.gif)

I have a similar build to yours in process.

Classy, very classy.

I have nothing to match that - only perhaps that I wish you all a Merry Christmas from a blowtorch hot (!) part of Europe. No need for winter tires!

Looks good Mats, when will you fire it up?

Maybe I could come over and take a closer look if you are around over christmas and the New year.

Houston, we have cranking rpm... (IMG:style_emoticons/default/biggrin.gif)

Got some work done today. Pulled the intakes off, removed the plugs and checked the plug gaps. All good. Proceeded to mount the oil filter, fill the engine with oil.
Then I built a remote start switch and hooked it up. *drumroll* It cranks! (IMG:style_emoticons/default/smile.gif)

(IMG:http://www.914world.com/bbs2/uploads_offsite/matsgarage.com-15176-1451149010.1.png)

Nice with a built-in oscilloscope in the tuning software.

Oil pressure is up.

And today I also verified that I have spark on all four cylinders and that my timing light was dead on arrival. Waiting for new intake gaskets before I can button everything up again.

Oh and the engine harness was finished today. Wired up the E85 flexfuel sensor and
cut and tucked the last remaining spare input/output wires.

Its alive! (IMG:style_emoticons/default/aktion035.gif)

Granted firing it up revealed a few issues to be solved.

1. The new hi torque starter doesnt disengage quick enough, you can hear the slight whine in the beginning of the video till it disengages.


2. Turning the key off doesnt kill the engine, it keeps running and I have to kill it via the laptop interface to the ecu. I'm not sure why this happens.

Attached Image

This is how I've hooked up the ecu, switched power from the post on the relay board to a separate relay that controls the power to the ECU.

3. Third issue is an oil leak from the left side valve cover. Suck having to pull the heat exchanger down to get access and fix it. Do I need to drain the oil before removing the valve cover?

Your first two issues could be caused by a single thing. There might be something feeding back into the switched power circuit. I've done that by putting the wrong type of bulb into the taillights, for instance.

You don't have to drain the oil, or remove the exhaust, to replace the valve cover. There might be a little oil in the rocker box, but the "resting" level of the oil in the crankcase is below the bottom of the rocker box.

And there will be even less oil if you jack up just one side of the car.

Way cool on your first start up. The independent injection is something I'm looking into as well. Does the crank sensor and wheel work well? I was under the impression that the sensor had to be mounted on the outside edge of the wheel.

I had no issues at all with the triggerwheel setup.
All my sensors are from Mario @ thedubshop.net Cant recommend him highly enough. Super guy to do business with if you want to go EFI. He's developing his own Megasquirt circuit board to be able to update aircooled fours to modern injection.

I found a thread earlier today (cant find it now tho) about the alternator backfeeding current when you turn the key off, just enough to keep the power relay energized.
The engine should die if you for instance push the brake pedal and this is exactly what happens to me. Turning the key off doesnt kill the engine but then pushing the brake pedal to light up the brake lights kills the engine. Apparently putting a diode in somewhere would fix this issue.

Started tackling the oil leak today. On inspection I saw that the left valve cover was pushed upwards, probably happened when I pushed the spring in place.

I also took down the starter motor hoping to find a reason for it squealing a bit when the engine starts but I couldnt find anything. I put the starter in my vice and hooked it up to a spare battery and it runs flawlessly.

https://youtu.be/fiwULhbUrrg
Here's a clip of benchtesting the starter.

https://youtu.be/h6CsDYiB2YI
Here's a clip of the engine start efter putting the starter back on the car.

Any ideas on how to fix the annoying squealing noise?

The last few weeks has been spend fixing issues found after getting the engine to start reliably. The biggest hurdle was the throwout bearing.

(IMG:http://www.914world.com/bbs2/uploads_offsite/matsgarage.com-15176-1455225577.1.jpg)

Last weekend the gearbox came out and I ordered a new throwout bearing and all the associated small parts.

(IMG:http://www.914world.com/bbs2/uploads_offsite/matsgarage.com-15176-1455225578.2.jpg)

While waiting for the parts to arrive i cleaned up the seats. They need to be recovered eventually but for now the California patinated cracked and torn vinyl will have to do. This passenger seat is the better of the two.

(IMG:http://www.914world.com/bbs2/uploads_offsite/matsgarage.com-15176-1455225579.3.jpg)

I also cadded up some baseplates for the new velocity stacks and had them lasercut at work. A good friend of mine got them welded up tonight.

(IMG:http://www.914world.com/bbs2/uploads_offsite/matsgarage.com-15176-1455225580.4.jpg)

For my birthday earlier this week I also had a package arrive that I ordered about a month ago. Two custom front mats with the Martini Racing colours.
