Mine is long gone. I put the vent tube up in a frame rail so it won't slosh fuel around but will still fill up quickly at the pump. I usually fill it with 5 gallon jugs now anyway though and have no issues.

Leafy is a traitor though, he drives a miata. His Subaru is weak sauce

Yeah I just got my swap finished and I was pushing fuel from the evap canister and the rotted vent tubing at the solenoid (long story). Instead of replacing everything I think I'm gonna rip it out and get ready to get the car tuned for next season. I'm looking forward to seeing you at some of the events, especially at Zmax which is 2 mins from my house (if you ever have a problem or need a garage to wrench in between the event days hit me up)

Super jelly about your proximity to ZMax. It's 2 hours for me coming from Cayce. Since I get my tuning done at 42 Autosports right there in Concord it's also super nice if you need parts/a lift as well.

Speaking of tuning, next year is an EFR turbo, killer b header, and E85 tune for me. Should be pretty zesty coming from factory manifold, Blouch 1.5xtr, and pump 93. The car was around 360 whp on 42's dyno right before nationals, these changes should net a number that begins with a 4.

And I'm shifting 45 lbs to the back of the car, and making a bunch of bushings out of delrin/metal/rod ends. And modifying some geometry. And and and

The rabbit hole, it never ends

Do you think the 1.5 xtr is a good turbo for auto x?

In 8cm it's fine. Back when I bought it Blouch thought the 10cm and 8cm would be very close in response. They aren't. I have a 10cm and while I've made it work it's slower to spool and recovery than I'd like. I pulled the data logs out of the ECU and it's .7 seconds if I stomp the throttle to go from full vacuum to full boost (22 psi) at 4,000 + rpm. If I had a 8cm to start with I might not be switching, but since I wanted to switch the EFR 6758 checks all the boxes. Quicker recovery, quicker spool, more efficient, and lighter.

Oh I know, I no longer tally what's gone into my car and like you mine will be a never ending build

I'll be taking my car up the road to 42 for the tune and some work. Great guys and I always get side tracked when I'm there and end up spending way too much time talking to the guys.

Wow, this thread is moving today!

Thought I would share this.

Installation of the 2015 STi 13:1 steering rack into a GD. Minor trimming of the subframe required. Should work for the GC with different tie rods also.

I saw that and think it's going to be great for people who weren't able to get a QRack. I guess they're out of business now. I have one of their 11:1 (or whatever the ratio was) racks in my car. You can see in the video I posted today how much my hands have to move on the wheel. The quick racks are GREAT when you're going through a slalom at 60+ mph!

Yeah, I can't wait for the first event next year. Even being only 13:1, it's a huge improvement. There have been a couple local courses (runway) that have put incredibly low speed slaloms at the turnaround. With the stock WRX rack my hands were pretty much flailing trying to zip through it.

I really want to do that to my wagon but the trimming of the subframe is a bit scary.


On the topic of Wagons , What do you wagon owners run wheel / tire setups like

I am looking at a set of 17x8.5 RPF1s with some 245/40 RE11s. I have a full V7 Spec C driveline.

What would you suggest ?

I would suggest you stick with what fits in your fenders unless you want to cut the fenders to fit bigger.

Just a note, I wasn't bragging about the QRack, just making a comparison available so you could see what it would do

It is a GREAT improvement. 1 of a few keys to making these cars work IMO.

No problem, I knew what you meant. my italics were more for my own sentiment that it's "just" 13:1, I always wanted one of the q-racks, but couldn't afford to do much with my car when I was in college.

It was painful selling my Q-Rack last year I had bought in 2005. It was a 11.5:1 version, was seriously my favorite mod. Except when my belt broke and I had to drive the car with no power steering.

Holy **** 0.7 seconds from nothing to boost. That blows. Your brain is literally going to melt and you're going to spend the first half of the year not blowing the tires off the car mid corner once you reduce that time by at least an order of magnitude with the efr. You still wont beat my sweet sweet 16" long runners and my lag measured in miliseconds.

You guys are lucky to have a 13:1 option I'm just sitting over here with my 15:1 rack, which was WAY the **** better than the 18:1 manual rack I had 2 years ago. Some day I'll figure out how to add a 1.5:1 steering quickener, then it'll be amazing.

You will need to make sure the car makes min weight, which if you're under a 275 tire will be 2,620 lbs. Shouldn't be a problem, but something to know as they will weigh you at the end of each day.

I emailed him I think, but it's been a while. I bought mine when they were cheaper but I do remember it was the same price for 4 rears as it was for rears/fronts.



I usually stay at the Super 8 in the town north. It's like $30 a night and clean. You're only there to sleep and shower, the rest is drinking time at my dirty trailer
I'll be keeping an eye out and see you there! I appreciate all the help man.

$30 a night sounds perfect to me! haha

I have no doubts I'll be spinning several times from the increased response. Right now I've programmed my right foot to just plant about .5 before I need the power to show up. Works well, but like you said, it means I'm going to have a bit of a wild ride next year

THANK YOU for the feedback on the 1.5XTR on the autox course. My 08 STI is a very mild SM build, but I've been toying with the idea of making further upgrades. Bigger turbo is one upgrade I'm considering, but I drove 2.1L wrx w/ a FP Green on the track a while back, and the lag was terrible coming out of turns (imho). Granted that is a large turbo though.

One turbo I'm considering is the 1.5xtr twin scroll, but I was still fearing lag. Glad to hear that the regular 1.5xtr (even with the 10cm hot side) isn't too terrible and can be manageable.

Hard to believe the Q-Rack guys are out of business with the outstanding customer service they offered. They promised me I would have mine in two weeks when I ordered mine, only took 3 months to get it. I will have to say it was the best mod I did for autocross. My wrx on big R-comp tires was tough to get through a salom until the Q-rack was installed. Subydudes lag problem was so bad that he was only beating me 2 secs a run HaHa! I can not imagine how fast that car will be with the new turbo! It takes a big commitment (money, time and fabrication skills) to run at the pointy end of SM and I need to thank Tim for alot of good advice. Maybe in a few more years of hard work I will be able to run with those guys.

My Q-Rack also leaked after my 1st autocross with it, leaked where the steering shaft goes in. It uses the same seal as a subura rack, we used oem seal to fix it. I added a power steering cooler and have had no more issues.

The Q-Racks use OEM housings but have different guts so, like carolinachill said the oe seals will work. Really anything on the outside you can use OE subaru parts.
