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.

It is actually smaller...engine displacement speaking.

Another thing to consider from them is their vehicle speed sensor. I have found that my engine ECU requires a vehicle speed sensor for the active valve time to function. I ordered mine today.

I was kinda burnt out on it. What Brit is doing is pretty much what I would have done and he is better equipped to do so on many levels.....which means he's as much of a lunatic as I ever was. (IMG:style_emoticons/default/biggrin.gif)

The car needs some serious mods to the front end to get more tire up front.
"The Kid" has plans for that but it is another project that will be a serious time/money eater.

You can get the whole bracket kit for $249 which includes a crossbar that is built to bolt to a Vanagon. However, I later found out that you can purchase just the two brackets that bolt to the engine block for ~$190. Give them a call, they can hook you up with what you need.

Great work, Britain! (IMG:style_emoticons/default/thumb3d.gif) I'm amazed that you're doing so much, so quickly. And it looks like quality sh*t too! Where do you find that kind of time? (IMG:style_emoticons/default/biggrin.gif) Keep it up.
And if you decide to come back down to San Diego this year, let me know. I'll come out and crew for you. Go get 'em, bud.

Few updates. Took a few days off work to make some progress before the holiday season gets underway. I also got a lot of parts in and I couldn't wait to get them mounted.

First off was to mount the pair of Turbosmart wastegates and finish the exhaust plumbing. Here you can see the general location of all the components.

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012081.1.jpg)

Both wastegates will dump back into the exhaust stream so that I can control the output noise levels due to sound restrictions at some venues. Both wastegate dumps are 1.5" and then merge into 1.75" before being dumped into the exhaust. After several hours of fab work with a "metal master" buddy of mine, it was all completed. Just have to get it professionally tig welded to call it done.

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012083.2.jpg)

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012083.3.jpg)

Here it is mounted in the car to ensure that everything clears and fits in its respective location.

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012084.4.jpg)

The location of the turbo and the mess of the header and exhaust plumbing has made it impossible to run the stock shifter bar. Therefore, I have adapted parts of a cable shift set-up to handle the shifted duties. If you remember, I only have 2 gears in my transmission and therefore only need to shift forward and back...pretty simple. Here is the transmission side.

Because this engine is "special" and has the TGV delete manifold, the Aeromotive fuel rails interfer with the AVSC solenoids (blue plug).

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012110.1.jpg)

However, by spacing the intake manifold up ~16mm I was able to clear the plug. I order a set of 16mm phenolic spacers from KSTech and everything clears like it should.

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012111.2.jpg)

The second problem with the Aeromotive fuel rails are the mounting brackets. Again, because they are supposed to be mounted to a TGV they don't fit my Spec-C manifold. Therefore I had to fab up a pair of brackets to secure them. Here you can see the difference between the new brackets and the ones that came with the kit.

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012111.3.jpg)

Here they are on the engine...all good.

I usually don't like to show new parts until they are installed, but I had to show off the custom Griffen radiator I got in yesterday. It is going to fit perfectly.

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012135.1.jpg)

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012136.2.jpg)

I also got in the ice box from Frozenboost.com. If you get to take a ride, this will be between your legs. Maybe I can hook up a "cool" suit for that hot days...hmmmm.

(IMG:http://www.914world.com/bbs2/uploads_offsite/sphotos.ak.fbcdn.net-364-1292012137.3.jpg)

Ok, back to the garage to continue working.

Looks great! Interesting how everybody has a slightly different take and process on fitting the Subaru engine. That header is wild!

How did you go about spec.-ing the radiator with Griffin? I notice it has unusually narrow end tanks - I guess to provide more core room? Did you make a model and sent them, or just sketches? I'll be going through the same process soon.

Looks like your having fun.
Let me know if you need an extra set of hands.

I'm putting the finishing touches on the shop. Plumbing in the compressor air lines overhead. Driving by about every other day.

Just about ready to start working on my daily driver. Oh yeah, I did buy an enclosed trailer. 20ft. Haulmark. TTYL.
