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. |

First thing I did was cut out the 914/6 bulkhead engine mount in front of the engine...you will see why I did this in just a bit. You can also see the nice stainless steel fuel lines that I installed here.

This engine also had an additional sandwich plate for oil temp sensor. This stack was way too long and would put the oil filter at the lowest point of the car. (IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1291656827.2.jpg) This is how long the oil filter mount bolt was to accommodate this length. I have since ordered and fitted a oil filter mount bolt from an N/A engine and it eliminate all the extra lenght so now I just have the oil filter mounted directly to the block.
