Blue Porscheru Conversion
I started this project back in May of 2014 and wanted to share the journey with my friends and family. There's something appealing to people about taking a left-for-dead vehicle and bringing it back to life. I hope this build thread is a bit different than the others. It's a Subaru conversion which is not as common. I am/was a newbie. This is my first car restoration, if you can call it that. My welds are not pretty, but I've improved and learned throughout this process. This is a great car for a first restoration. It's light, simple, and very cool- mid engine with a targa top. This is the plan- We are starting with a 1971 tangerine 914 with light to moderate rust, nothing too serious. The original engine was a 1.7. Like so many other 914's it ran but has been sitting for a long time. The engine seems too far gone to try to rebuild it= lots of rust and corrosion. Powerplant: 2003 Subaru Impreza TS 2.5 SOHC, Natuaral- No Turbo, Why? Plenty of Power for me and no turbo lag. See Engine Choices thread. Transmission: Subaru 5MT 2003 Impreza TS ECU from: 2003 Subaru Impreza TS Electronics: Wiring Harness simplified by Small Car Performance Axles: 944 axles and CV's with Subaru inside CV- 4 lug for now. 914 suspension. No fender flares Voltage Blue Metallic: (Honda color), Painted Sail Panels.

I am not a certified mechanic. There are many that have pioneered the suby conversion before me, but this is my story. Hope you enjoy this thread!

When you think about it...
People keep telling me it's not that hard when you get the wiring diagrams together and separate the fuel injection and ecu from the 914 wiring. We will see. At this point I have collected the wiring diagrams from the 914 and the Chilton's guides from each car. (IMG:http://www.914world.com/bbs2/uploads_offsite/i1301.photobucket.com-17072-1437974914.1.jpg) Useful Links: Pelican Parts Wiring Diagrams Jeff Bowlsby has a ton of great information on his webpage on wiring harnesses, diagrams, and sketches. He also rebuilds 914 harnesses. Jeff Bowlsby's Technical notebook, an amazing resource for diagrams/sketches. The guys at Outfront Motorsports will build custom harnesses with the EMS stinger. Small Car Performance stripped my Subaru harness and provided me with the shortened oil pan and engine mount. =Search]Small Car Harness Modification Page. Small Car Performance harness modification kit Small Car guide to Subaru engines. Which have immobilizers, which to choose when deciding on a donor engine. Subaru wiring diagrams for conversion How to route your wiring in the 914. For the do-it-yourselfer, I have found portions of these threads very useful:
This ECU is programmable and can plug into a computer (term). Here's some pictures of my wiring stripped out of the Porsche. At the time, I had no idea how much of this I would be using with the Subaru harness. Beside the 914 ECU and wires to the engine, I will be using most of this wiring with the stripped down Suby harness. Subaru Harness. I wonder how many feet of wires go into this? (IMG:http://www.914world.com/bbs2/uploads_offsite/i1301.photobucket.com-17072-1437974914.2.jpg) Speedo labeled. Unfortunately, using the Suby tranny, I won't be able to reuse the classic speedometer, although there is a guy who converts these to use the Subaru. (Look for Link) (IMG:http://www.914world.com/bbs2/uploads_offsite/i1301.photobucket.com-17072-1437974914.3.jpg) Another Speedo Pic. Look for Jeff Bowlsby's Tech notes linked above for some sketches of the wiring diagrams for this. (IMG:http://www.914world.com/bbs2/uploads_offsite/i1301.photobucket.com-17072-1437974914.4.jpg) Again, Jeff has these all sketched out. (IMG:http://www.914world.com/bbs2/uploads_offsite/i1301.photobucket.com-17072-1437974914.5.jpg) The plan is to update the corroded fuse box... (IMG:http://www.914world.com/bbs2/uploads_offsite/i1301.photobucket.com-17072-1437974914.6.jpg) Update to something like this: (IMG:http://www.914world.com/bbs2/uploads_offsite/i1301.photobucket.com-17072-1437974914.7.png) I worked with Mao of Small Car Performance for the Subaru wiring harness. First I ordered the harness from Ebay, which came in a large box, weighing about 40 pounds. It was shipped to Small Car in Washington State and returned in about a week, weighing maybe 10 pounds, and everything labeled. I had shipped them the ECU with the harness. Update: It's time to get back to the wiring. We are going to replace the 914 portion of the wiring harness with new wiring and new technology. The fuse box will be replaced with blade fuses. The old wiring features multiple grounds where it's not necessary, multiple fuses for the lights and poses other issues. We thought it easier to start over. The speedometer will be replaced internally with a new VDO speedo run electronically. Here's a picture of three harnesses, the old 914, new harness, and Subaru portion.
