One other item that I finally finished up is a homebrew Fuel Cut Defencer. The stock Subaru ECU cuts the fuel at ~12 psi of turbo boost. Since I'm running an HKS electronic boost controller, I don't want the ECU to shut down the fuel when I crank up the boost -- instant piston meltdown. Basically, this system tricks the ECU into thinking the boost -- and therefore the maximum 5V signal from the sensor -- is at an acceptable level. Some call it a clamp, and it is mounted between the boost sensor and the ECU. Either way, I've got about $10 in this setup, saved myself about $75 and got to play with more electronic stuff.

Yup, the Flowmaster description says it will be "aggressive." I'm hoping the turbo will quiet things a bit but if I find it is too loud, I'll cross that bridge then. But I first gotta get it running. Keep up the great progress on your 1.8T project!

After weeks of troubleshooting, testing & re-testing of fuel injection components and wiring, I finally realized that I had my fuel inlet/outlet lines backwards. (IMG:style_emoticons/default/headbang.gif) Swapped 'em, and it roared to life!

(IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/piratenanner.gif)

Of course, I immediately discovered some small coolant leaks and I've got my spare ECU mocked up for now, so I've got plenty of tidying up to do.

I've uploaded a video to Youtube from my iPhone, but it isn't fully processed yet. I'll update the link once it is up. But in the meantime (IMG:style_emoticons/default/beer3.gif) (IMG:style_emoticons/default/beerchug.gif)

Okay, I just checked and the video is now up-n-ready. You can see and hear it at:

Sounds pretty mean! It's a great feeling firing an engine up for the first time. Congrats

Looks like I need to rebuild the turbo, as it is pushing oil into the turbine side and smoking like a mosquito control truck. (IMG:style_emoticons/default/barf.gif) I'm using a Mitsubishi TD05H-16G, which was used on late 1990's Subaru WRX engines in Europe and Japan. I'll take some pics of the rebuild when the kit arrives later this week. Supposedly good for up to 350hp.

I was able to eliminate the coolant leaks and tidy up some of the wiring today. This is getting fun again!

Funny, on my Suby, after weeks of troubleshooting, testing & re-testing of fuel injection components and wiring, I finally realized I was out of gas. (IMG:style_emoticons/default/biggrin.gif)

It runs, that's a good feeling (IMG:style_emoticons/default/piratenanner.gif) next step (IMG:style_emoticons/default/driving.gif)
Cool, I have to read more when I get home from work.

Sweeeeeeeeet!

What about a oil line restriction? Is it a ball bearing turbo?

Nope, the turbo uses two brass journal-type bearings, and has two rubber o-rings and two spring steel seals to control oil. The kit is ~$100, so it is not so bad. But before I remove the turbo I'll pull the exhaust manifolds to see if there's any oil pooled there; maybe my valve seals are bad from sitting so long...

Yeah, I completely "un-loomed" my formerly beautiful wiring setup so that I could trace each wire when I couldn't get it running (IMG:style_emoticons/default/headbang.gif) Boy did I feel stupid when I realized my fuel lines were backwards!

The plan has always been to debut it at WCR (2010, 2011, 2012...). Hopefully WCR 2013 will be the one. (IMG:style_emoticons/default/biggrin.gif)

Geoff also there is a chance the rings are stuck in the pistons from setting. Just run it for awhile to see if things loosen up and it might clean itself up. When I got my jhots 96 legacy outback tt motor I read up after checking the oil and finding it very black and burned smelling and read that a lot of owners didn't change the oil like they should knowing they wouldn't be keeping the motor long enough to justify the expense. The motor I have uses hydraulic lifters and they sometimes are stuck and won't pump up without a dissassembly and cleaning. The 96 motor has a oil restricter in the head where the banjo fitting is to the turbo oil line. It looks to be about .065

Your motor sounds great though. There should be a restricter in the oil line to the turbo. I think it's in the fitting where the oil line goes on but can't really remember right now.

I can hear my son's sti coming from about a 1/4 mile away. It sorta sounds like a helicopter from a distance when it is at low rpms.

Also you might want to check to see if the intake tract is oily, maybe at the throttle body hose connection. The ic could get a lot of oil in it. Run it na forawhile to see if the rings loosen up.

I used my 1976 911 axle shafts that I had laying around, shortened and re-splined by Dutchman Axles. See post #188 of this build blog for details. If memory serves, Dutchman charged me ~$150 to machine the pair of axle shafts that I sent them.

Turns out the turbo is not pumping oil -- at least not into the intake side, since it is bone-dry. However, in my haste to get the engine running, I mickey-moused the PCV system. The PCV hose from the crankcase vent into the PCV valve on the intake manifold is SOAKED with oil and my spark plugs are now oil-fouled. (IMG:style_emoticons/default/sheeplove.gif) At least I didn't fill my A-W intercooler with oil!

I'm correcting the PCV system now, including re-hashing the piping to the oil catch can. I'll need to get two aluminum nipples TIG'd onto a 90 degree aluminum intake pipe to finish it -- hopefully later this week. Already put new spark plugs in. I'll post a higher-resolution video once I clean this thing up and eliminate its mosquito-smoke antics...
