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. |

The sight gauge you are showing looks like it uses Legris push-to-connect fittings and probably a clear nylon tube. We use them for fluid systems at work because they are low cost and pretty reliable (leak-free) fittings. Search push-to-connect in McMaster and pick out the desired fitting. They sell elbows with one NPT end and a push-to-connect end as shown, so you can just have 2 NPT bungs welded into your tank, screw the fittings in, and be done. Compression fittings will also work, but I don't have a huge amount of faith in McMaster's stock. They might work fine, but when I'm shopping for compression fittings I always go to Swagelok since the prices are comparable and the Swagelok parts are significantly higher quality. If you want to go compression fitting, the P/N for an aluminum Swagelok elbow with 1/8"NPT on one side and 1/4" compression on the other is A-400-2-2. To switch to stainless change the A with an SS. If decide to go that route their website has a selector which has all of the fittings you could ever want. BTW: The project looks good! (IMG:style_emoticons/default/smile.gif) |
