I did a little more work on the car tonight.

45° coupler arrived and was installed. I had to trim another ~1.5" off the red pipe on the turbo side. The 45° coupler was extra long so it was fairly easy to get the length to something that would work. With this coupler the reverse flow setup seems like it will work perfectly.

I have noticed that since I switched the piping setup, my boost (measured at the intake manifold) is a couple PSI lower. I'm assuming that is because the air going into the manifold is colder and more dense, while the air pressure coming out of the compressor (and controlling the wastegate) is unchanged. At least I hope so... Or maybe it's just the weather? Haha.

I also swapped out the intake for something a little less beat up. The old one was just looking pretty worn out. I got a new filterand used the short intake tube that comes with the TurboXS FMIC kit. It looks a bit better with a newer filter instead of the old worn out one.

And what's this...

I also installed a set of Agency Power Equal Length headers. They are wrapped with DEI Titanium wrap. I got them used and they came fully wrapped, but a couple spots were tearing (around the slip joints). I also got about 20ft of spare wrap so I touched up the spots that had issues. It came out looking great.

Install went smoothly. No fitment issues and no leaks. The old header-to-head and header-to-uppipe gaskets looked like they had been sealing well. The sound changed considerably (as with any EL header). Much quieter. Haven't tuned it yet so I don't know if it increased power at all.

I also removed the front sway bar while I was under there. One of the endlinks broke (with quite a loud pop) the other day when backing out of my driveway. I just removed it completely since it wasn't connected anyways. Ended up having to cut one of them off.

Here are a couple more shots of my 2002 WRX Bugeye with the 2004 STI BBS wheels and WRX hood.

I determined my ID 2000 injectors were installed (by me) with the wrong gaskets. I bought them used and they didn't come with the right ones, so I just used an OEM gasket on the bottom and nothing else. After a little research I found that it needs two gaskets on the bottom and one addition one on the top. I ordered them from ID and they came today so I installed them a little bit ago. Here is a photo.

Left is correct and right is how I had them (incorrect). I noticed it because I had some occasional leaks at idle/rest and then I checked and found that the injectors could move up and down considerably (when the rail was bolted down). With all of the correct gaskets in place the injectors can still rotate, but there is no up and down movement. This should help ensure a good seal on both the top (fuel) and bottom (boost) of the injector.

I bought a cheap ELM Bluetooth adapter in an attempt to run the Torque app on my Bugeye. It wouldn't log live data and I spent the day yesterday trying to figure it out. I eventually have come to the conlusion that it is due to the Carberry ECU ROM. The hardware and app works perfectly on my 2012 Forester. A few others with Carberry have noted the same thing. So far I don't know of any workaround.

Resolved: Carberry ECU ROM doesn't have the same PID's as normal, so it connects, but won't read the realtime data.

The ELM Bluetooth adapter and Torque app work perfectly on my Forester.

I thought my boost gauge was broken (ProSport EVO). It was ready low (vs. the ECU sensor) for a while and then it just stopped reading at all. Just showing 0 all the time.

I figured it was a dead sender, but last night I found that the inline filter was broken completely in half! Big boost leak there! Didn't notice because I'm on speed density.

I replaced it with a straight fitting and now the gauge is working perfectly. Turned the MBC down a little because boost went up a bit now that the leak source has been fixed.

Here's a quick speedo video with the EL header installed:

Weight reduction since the last time at the track:

Removed all speakers: 5lbs
Swapped to WRX hood: 20lbs
Swapped to 04 STI wheels: 21lbs
Swapped to EL header: 10lbs
Removed front sway bar: 7lbs
Removed rear sway bar: 10lbs
Removed rear bumper beam: 30lbs
Removed scissor jack and tools: 6lbs
Removed trunk liners: 3lbs
Total weight saved: 112lbs

Weights are based on what I could find online. I didn't actually weigh anything myself...

I did a few last minute things last night. Swapped the front right strut (from wagon to sedan). Front left was already sedan so the mismatch was making the camber way off between sides. Then I removed the rear sway bar.

Later in the evening I removed the rear bumper beam. It was a huge pain. I broke all the plastic clips and half of the bolts. Ended up having to cut them off. Tight space so I cut the bolt heads into 1/4's and then snapped them off.

After all that I noticed a transmission fluid smell. Look under and find a huge puddle. Apparently I pulled the axle out of the transmission while swapping the strut and then it leaked a bunch out. I put the axle back in, then did a full drain and fill on the tranny.

Looking forward to the track this weekend. I am hoping all goes well and I can put down a better time than last time!

This is what is posted on Cars 101:

• 2002 WRX Sedan 5MT: 3085lbs
• 2004 WRX Sedan 5MT: 3085lbs
• 2004 STI Sedan 6MT: 3263lbs

So if we'd assume the STI weight is basically what my car is (GD chassis with 2.5L and 6MT) and I weigh in at 29XXlbs, then that would say I've pulled out 200-300lbs total. I had many other things pulled out prior to going to the track before:

• Spare tire
• Trunk floor
• AC compressor
• AC condenser
• Front bumper beam
• Front U brace
• Undertray
• Fender liners
• Fog lights
• Lightweight battery
• Radio
• Aftermarket uppipe
• Aftermarket downpipe
• Etc...

Two broken axles and one 10 second pass.

Full details on the runs from Proving Grounds:

Event: 1/4 Mile at MAPerformance Proving Grounds 2014.2
Location: MN
Ambient Temp: 70F
Elevation: ~1200ft
Weather: Sunny and Clear
Tires: 235/45R17 Federal 595 RS-R Tires on 2004 STI BBS Wheels

Car: 2002 WRX Sedan
Tuner: Nuke @ NF Performance
Transmission: 2012 STI 6 Speed
1/4 Mile ET: 10.99s
1/4 Mile Trap: 126.0mph
60': 1.67s
Target Boost: 30psi
Target AFR: 11's
Fuel: E85

10.99s @ 126mph with 1.67s 60' (street tires)

I drove the car ~2 hours up to BIR on Friday and made my first pass in the afternoon/evening. I was launching at around 5,500rpm's and only building a few psi of boost off the line (fuel cut launch control), but it was still enough to spin the tires hard and I broke an axle on the very first launch (driver rear). Spent an hour or so swapping in another OEM WRX axle.

I did a few passes with no launch and was trapping around 126mph consistently. It did mid-11's even with a ~2sec 60' time. I did another pass with launch control and it did a 1.6s 60' but I missed third gear. On the next launch it had a little hop, but it did another 1.6s 60' and I made a pretty clean pass which resulted in the 10.99s slip.

On the 10 second pass I shifted the car into 5th to make it through the traps. I had been going through in 4th for my earlier passes but the car didn't feel like it was pulling quite as hard up near 8,000rpm's so I decided to shift instead. It was almost time for the track to shut down at that point but I decided to do one more pass. Spun hard and broke the passenger rear axle.

I swapped the axle (I had 4 spares with), but then I decided not to run drag on Saturday and Sunday. It cost more money and I was tired of changing axles. On Sunday I did roll racing. I was neck and neck with several other cars in the same power range and I pulled on a stock GTR. Then I drove the car back home. Overall a great weekend and I'm happy to be in the 10's!

Put on a KillerB header last night!

Unfortunately the custom EWG setup wouldn't clear my downpipe so we had to improvise an EWG block off plate. I'll probably have to pick up a different downpipe to make it fit.
