The mod list is suprisingly well put together, the graphs are exemplary and the engine bay is flawless (*-3 stickers*)

If id start over, it would be alike minus:
I would do a 0.80 twinscroll housing @ 18psi, using ported heads with oem valves and guides using 1.65" EX port to 1.5" throught a conical taper primaries and 1.5" secondaries. All That to be coated. While the heads are off all it needs is a set of drop-in pistons with WPC by cosworth @ 8:2 CR. ID725s would be best for such an application. The longer the IPW the better, as long as you have 12% more pulsewidth on reserve on your tune.

I have a couple of questions.

Kartboy endlinks for the sake of it?
Can you provide feedback on the 2015 sti rack. Did your 2011 oem rack take damage or was this an upgrade to the quicker?
Camber bolts? Anything over -1.1' is a liability for streetuse. Tramlining, uneven wear, worse grip in one-lateral braking, and worn insides quick which makes things progressively worse.
When did you change out your clutch? Hows the stage 1 compare?
Do you have a wideband? Spoolup is beautifully lean. I love the accessports.
Looks like she has another couple % area-under-the-curve available on tuners demand...

What do you think contributed to the fall off as you approach 7k rpms? I thought the efr would keep pushing there. Is it just a matter of the 91 octane and 20 lbs?

I too want to hear about the 2015 rack. Do you have another thread about that upgrade? (Sorry I'm on my phone and can't search).

It's something I want to do on my 04 and I'm wondering how big a pain it is to mate up.

A little porting might have been nice, just didn't want to do anything that would negatively affect the low end boost threshold and response. Hence the bone stock heads. The engine is built for e85, which is why Wiseco 8.9:1 drop-ins are being used. ID1000s are left over from my previous setup (stock turbo on e85). This tune is just to hold me off until the rest of my fueling is in place for flex fuel!

Pretty much. Figured I would do them at the same as the swaybars. If I had to do it again, I'd go with spherical end links such as RalliTEK.

I ran over something on the freeway one night that smashed into my front subframe. Needing to replace the subframe, I figured it was a good time to do the steering rack too!

I love everything about it. The install was a cakewalk, it bolted right up to everything like it was made for it. The ratio is noticeably quicker and feels nice and tight. No more slop, every little input gets a response from the front wheels. IT'S AMAZING! Definitely one of my favorite mods.

Camber is maxed out for autocross. The car is not DD. One of the next things on my agenda is suspension, whether it's struts and springs or coilovers.

New clutch went in at the time of the rebuild. Had to get ready for the gobs of torque it would eventually face!

I'm not super happy with its street manners. It's heavy and shudders like a mafk until it's warm. I can't get up my driveway into my garage without it burning and stinking up the place (I honestly don't mind the smell &#128518. We'll see how it holds up when we turn up the wick!

Yes. AFR seems to be 11:1 on the dot during WOT on my gauge.

Agreed 😉

Nick couldn't push it too hard, he had to back off quite a bit after his first couple of runs. Higher compression combined with 91 octane didn't play well together. The first couple of runs started out amazing!



Again, this tune is just to tide me over until I have everything in place for flex fuel. Nick anticipates about another 100whp on e85!

Probably a combo of stock heads, higher compression, piss fuel, and a conservative tune. Overall, it feels really good! Pulls nice and strong and barely drops off before redline. I usually don't rev it out much past 6.5k anyway.

I don't have a thread on the rack. Thoughts posted above ^^.

The rack isn't a direct swap in the GD as it is with the GR. Not sure if someone has done the swap in a GD yet, but it would certainly worth it if you figure it out!

15 rack didn't work in my 07, yes you could trim the tie rod ends, make a spacer for the one bolt that requires it, bolt it up after clearancing the cross member, but... the input shaft of the rack and the universal joint don't line up sufficiently when bolted to the cross member as it comes out at too shallow of an angle. If the rack could be rotated on its axis maybe 10 degrees it would be fine, but that makes it a bit more difficult to bolt in

Oh I believe it feels great! I've got my hybrid on an 18G and the power band is actually quite similar. Mine also feels like it pulls all the way to red line, despite the graph showing the slight drop off. It's hardly discernible.
I just thought the EFR would hold better... but you're right, those contributing factors are likely the hang up.

Some updates! I'm just about ready to move forward with flex fuel. There were a few things I wanted to address before diving in.

First off, I am pleased to report that the IAG AOS is working great, not a drop of oil was found in the intercooler! However, I found a small leak on the return line where it reconnects with the crankcase vent port. Obviously the skinny plastic zip ties that were provided weren't cutting it, so I went through and clamped all of the connections. Hopefully that does the trick!

Now, something I have been dreading for a while. I have noticed a bit of a click every time I push in the clutch pedal. Instead of looking past it any further, I took the wiper cowel off and found this..


Thankfully there's a fix that would keep me from having to pull the dash and reweld it.

http://www.wrxforums.com/forums/84-d...s/15436?page=1

Also orderd a clutch master cylinder brace to help keep the other spot welds intact.

It turns out I ran into some heat issues. I pulled the downpipe to inspect the turbo and found this!





Thankfully all of the wiring was undamaged. A fresh layer of conduit coupled with some heat reflective tape should just about do it.



..and a bit of extra measure to make sure that doesn't happen again!




The ceramic coating alone clearly isn't enough, I should have done this in the first place. Live and learn, I guess.

Also pulled the triggger on these, because what the hell!

I highly, highly recommend ditching the stock manifolds and going to a good ELH like the Killer B. You are leaving a lot on the table with this setup. It will help a lot, especially on E85.

Flex fuel tune is complete! Updates posted up top.

Due to stock rods, the car was tuned on a very conservative map where AFRs and boost were kept down a bit. Harvey stated we could have made upward of 460-470whp with more boost and leaner AFR. We collectively decided to not push it too hard. Overall, I am very happy! We easily reached my goal of hitting 400whp, while still having some room to grow if I ever decide I need more power.

What an awesome day it was! While the car was being dialed in on the dyno, we got to watch the solar eclipse as it progressed. Jerry had a filter for his camera and was able to get some pretty cool shots.





This one is my favorite where he was able to pretty clearly capture some sun spots.


A special guest also showed up for some dyno time after mine was all done. Just a little project car by ASF Machine called the Dick Smasher, nothing that special..

Flex fuel ftw! Wish it was available where I'm at

Do you know how much duty cycle near redline , & preload you had & which spring? (& how much more boost do you think it would hold?)

(I'm at 24-25lbs, but it's tapering more than I'd like(down near 20lbs) after about 5k. 12lb Spring & 7mm preload with the 4port Mac). I'd like around 26 tapering to 24 at 7k.

Was Joe just doing his breakin, any full boost runs?? I need to get something other than photobucket so I can post up some pics of another wrx (setup for road racing)with a setup like Joes-except he had nitrous as well. & it was a no expense total race car build. Lol

I'm not sure about WGDC, I can get some logs and report back. I only put the standard 2mm of preload on the actuator with a 1 bar spring. I've heard these turbos have trouble holding higher boost toward redline at altitude. A rotated EWG 7163 build I have been following had a similar issue. They were able to achieve 24psi, but it tapered down to ~21psi at redline. My car doesn't seem to have any trouble holding 23psi out to redline...

I think they were trying to make some real power with the Dick Smasher, but ran into a few issues on the dyno. They were having trouble getting the car to rev out, it seemed like it was losing spark above 5000rpm. They tried new spark plugs, didn't work. They tried spacing the crank sensor, didn't work. I didn't stick around too much longer after that, but I ran into Joe at the Rocky Mountain Subaru Festival this last weekend. After adding some resistors from the harness to the LS coil packs, they were finally able to rev out to redline and start making boost, but had to call it a night. They're still ironing some things out and plan on finishing up soon. Can't wait to see what it does!

Give Imgur a try. Seems like it's working out alright for me, so far!

I have a similar setup witj the FR 7163 stock location. I'm using the mac 4 port and turbosmart with the original spring(14lbs I think) also with the 2mm preload. Running a stock header and catted dp as well along with stock heads.

Was tuned at iag by junior for flex fuel. I told him I just wanted 400 ft lbs max on e85 tjen just let it eat after that. Ended up with 460 hp at 7000 where he shut it down (still climbing though) at 27-28 lbs of boost.

I logged a 50-100 pull recently in 3rd (2013 wrx) and it peaked at almost 29 lbs of boost at I believe around 60% duty cycle. It timed out to 5.1 sec so the dyno #'s seem to jive.
