For those who don't know me or the car, I have a '74 914 that is a dedicated AX car. It previously had a high compression 2.7 6-cylinder motor and made 205hp/205ft-lbs at the wheels. This set-up wasn't all that bad considering that it won the 2008 and 2009 914 Shootout events, however the quest for more speed continues.
Here is the car in the 2010 season trim. (IMG:http://www.914world.com/bbs2/uploads_offsite/dragracevws.com-364-1291656786.1.jpg) I have recently sold the 2.7L 6-cylinder engine and all the remaining 914/6 conversion parts. I have used the proceeds to fund the conversion to Subaru power. Now most would say that a Subaru conversion can be done on a budget, however I have found that the money goes flying out the window when doing something like this. Regarding the engine...logical choice would be to go for a EJ257 2.5L USDM STi engine. However, all the SCCA rules for AX are built around displacement which in turn dictates the minimum weight. Therefore, I have gone with a JDM STi version8 Spec-C engine which is a 2.0L, twin-scroll, hand ported/polished, 8500rpm animal. I will get slightly less hp and torque numbers than the 2.5L, but save 150lbs of weight. |

While waiting on more parts, I decided to start tackling the wiring nightmare. Unlike a lot of swaps on here, I have no WRX to compare to. Nor was I able to initially locate the proper wiring diagrams. Therefore, I started by mapping out the entire engine harness. This should be all the wires that I need to make it run.
(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1291657038.1.jpg) Here is my daughter lending me a hand. (IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1291657038.2.jpg) Here is the harness about 90% done. I have a few more issues to work out in regards to main power and ignition power, but it is basically ready. I will clean all of this up and make it look nice and pretty after the engine is running. (IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1291657038.3.jpg) Here is the engine with the harness back installed and just about completed.
