I have recently purchased a 1973 Porsche 914 roller chassis. I found and purchased a 2004 Subaru WRX engine with the stock ECU. The engine and ECU did not come with the wiring harness that connects the two. My question to all of you gurus is this... What do I have to do to make this work? I have heard I am embarking on a nightmare, but I figured someone here should be able to help. Please let me know any tricks of the trade to help me install this motor and kick the butts of all the folks here in Vegas who are putting Chevy 350s in their 914's.

You can always contact LIC Motorsports for wiring harness questions. They have done a lot of EJ20 engine swaps so they should be able to help you out. Ask for Noah or Adam!
I don't mean to be a jerk, but if you are asking these kinds of questions then you probably aren't skilled enough to do this swap yourself. It will require fabricating to mount the engine, mate the tranny and sort it out. You need the help of a professional shop that has some fab skills.

Silver Arrow,
Maybe you should take a little more time to understand what I was asking. I was not asking how to mount the motor, which has already been done. I was not asking how to mount the "tranny" (which btw is correctly termed a transaxle), that product is called an adaptor plate which has been manufactored for a while now...That product has been purchased and installed. I was simply asking how to connect the ECU to the engine. Furthermore, I own a Car Stereo shop here in Vegas that is right next door to Renegade Hybrids (www.renegadehybrids.com) they are one of the only companies that produces a quality conversion for Porsches. The only problem is that currently they only work with Chevrolet 350ci small blocks as the power-plant. I do not want 30+ year old technology in my 30+ year old car. I wanted to update this little piece of crap that I have sitting in my garage to something cool and appealing to the younger crowd. I will be sure to send you pics of the 74' 911 that my shop is putting well over $150,000 in a total rebuild just as soon as we finish.
Sorry if I came across like a jerk, but you could have been a little more respectful.

Craig, Thanks for the heads up. I was directed to this site last week. We have fabricated a proprietary engine mount. As soon as it gets back from powder coating, I will try to post pics.

I apolegize, it sounded like a guy who scraped enough dough to buy the 914 adn engine with just an idea of what he wanted. I was trying to save you alot of headaches and expense if that was the case. If I affended you, I really am sorry. See way to many of those projects turn into a nightmare.
This little car is pretty cool. The GVW with fluids is just a shade under 2,000 lbs. The idea is that a light weight, mid-engine, rear wheel drive with 300ish horsepower should be a real kick in the pants. I feel very fortunate to be able to replace the stock 2.0 horizontally opposed VW engine with a Subaru that is similar in configuation, but one helluva lot cooler. It seems that most of the Porsche people don't really like what I am doing, but hey, it is my car...
It is crazy, the amount of people that I have met because of this posting. Some of you have asked why I am doing this to such an ugly car. I agreed with you up until I saw some photos of these 914's at www.ultimate914.com that were outfitted with wide body kits. I just think they take on a totally different look. I am so freekin stoked to get this on the road. I want that rad blow off valve sound, and a low rumble exhaust note. Any ideas?
I also have been looking into this conversion and am waiting for someone to develop one. I live in CA. and the smog game is one that I am tired of playing. The 914 is smog exempt and still available. Let me know if and when you finally get this going.
We are just about to begin the fitting of the new WRX engine. I have purchased a complete wiring harness, ecu and all of the necessary adaptors. It is just a matter of time before the installation is complete. Our engine mount is a full cradle mount wich I believe will hold up better than the other available options out there (cantilever mount).
to answer some of the other questions...
the stock 914 1.7liter produced around 70hp and 45 ft/lbs of torque.
the stock 914 transaxle (901 transaxle) can handle right around 300 hp and 300 ft/lbs torque after that, you will need to get into a 911 transaxle (915 transaxle) which is good for around 450, from there you move into the 930 transaxle which will handle around 700 ponies...
