My first events are here in Wilmington, both at the Cape Fear Community College North Campus. On 11/31 it is the Turns for Tots charity event and on 12/1 it's a non-points event.
You should try and hit the cherry point event on the 16/17 nov. Huge venue and lots of runs.

Also whats wrong with stock turbo? Martin has a vf49 on his sti, 0 lag and spins up to 8k+ and in the 400 ballpark. he seems to be doing alright as its probably one of the best prepped Subarus in the country.

I'll have my VF for 2014, but we wouldn't be auto-xer's if we didn't look for that next tenth or two.

In all seriousness, I think they give you 90-95% of what you'd need for many sites, but for faster sites / Lincoln, I think we'd want something that doesn't fall off at the rate of the VF's above 5k. It is impressive how well Martin/David have done with their setup, so it's hard to argue that a different turbo will make a huge difference.

I think the quick spool of the stocker is great, but the HP is not entirely up to snuff. The west course this year was all about mid-range and top end power. The Evo's with their stock turbo were perfect, the STi's suffered there. East course with all the digs out of corners, sure stock was great there. The reason we're all interested in the EFR stuff is it seems to be spooling like stock turbo's with a lot more power in the mid range and top end.

Good luck with that. I know haltech came out with a solution for knock recently but if they're trying to do it with software and not a sound processing chip I would just run an external knock box with an analog output hooked up to the haltech.

Anyone have any experience running a staggered set-up. As in 315's up front with 275/285s in the rear.
The thought is to mitigate overheating the front's, while still allowing the rears to come up to temp.

Problem is if you go larger than 275 you need to weigh 200 pounds more.

I'll be researching and figuring out. I've seen the 3rd party knock box with input to the haltech before, so if their solution isn't good enough that'll be where I go.

I've seen staggered setups, they don't work that I've seen. If you're not getting the rears up to temp, you're doing something wrong. You'd need to do the 275's for diameter, and then you wouldn't be able to rotate tires (minor issue, but still an issue).

You know, the longer I think about it, the more tempted I am to skip my test with the 275's and just jump right to 315's on 18x11's. It's 8 extra inches of hoosier for 200 lbs.

Here's a video from a few weeks ago, still have some things to sort out with the car but i'm generally pretty happy with how things are going.

Had fun closing out the season back in my Subaru, feels good to have some torque again. I’ve got some big plans for over the winter. New dampers, aero, some custom bits from tssfab to get the geometry back in line etc.

I'm currently waiting on the usual XXR sale after thanksgiving to get a set of 18x11's. Already have a pair of used 315's to test fit with. The flares are just sitting there waiting to rivet on.

I was just getting used to how wide the car was, and here I go making it even wider

I think i'm gonna give the WRC flares a try. I think if i'm creative with the cutting i can get the 315's under them and i like the look of them much better.

I desperately need new coilovers before i go bigger on my tires...don't think my 9 year old BC's are gonna hold up to much more unsprung weight.

I'd be more worried about spring rate increases needed from the increased grip and how the BC's valving would deal with it instead of how the body of the coilover would deal with the increase of unsprung weight.

That is what i was talking about. The spring rates would need to be changed to deal with the increased unsprung weight and obviously the grip difference.

However, i'm also worried about the cheap pillowball mounts they used in them...the body of the coilover isn't gonna come apart, but the mounts aren't going to fair very well to the increased load.

Just doing drop in's, or anything else? Looks like high compression slugs as well.

Try setting up so that you can maintain steering angle or gradually unwind the steering so the car will accept more power towards corner exit. The tightest radius should generally be near the start of the corner. i.e. Slow in, fast out.

If it's the car understeering, it's all the more important to do the above.

Below are the basics on the engine (I've got a build thread on iwsti to keep track of things & get feedback); I want to get most of the internals done now even though I'll just be running the stock turbo. If/when the upgraded turbo happens, I hope to have minimal changes.

- Block: ACL Bearings; Eagle Rods & CP 9.0 Pistons
- Heads: PnP heads & Valve Job; SuperTech 0.5mm oversized Valves; GSC Beehive Valve Springs
- Fuel: DW65c Pump, DW1300cc Injectors
- Boost: Polished Stock VF48; GS Uppipe w/Tial 38mm EWG; GS 3-Port Soleniod
- Intake: AEM CAI; Silicone Turbo inlet; PnP Manifold
- Exhaust: Equal-length headers (TBD);Custom turboback w/turndown
- Misc: Lightweight Pulley; ACT StreetLite Flywheel; Killer B oil pickup, pan & baffle

You'll need to run E85 or race gas most of the time to take advantage of the high compression. It'll feel better off boost, but take less timing when you try to turn it up. Who's tuning it? I liked Pure Tuning when I was in Ohio. Bit of a drive from Cbus, but they're worth it. They like race gas from what I remember since E85 isn't as consistent. You'll need it to increase timing/boost to make the power.

No cams for your valves? I don't see a reason for the valve springs unless you plan on spinning higher than 7,500.

Make sure to plumb the EWG back into the DP, or make it exit behind the driver. That's a gotcha for a lot of SM Subaru's/Evo's that I've seen.

Otherwise, your list looks a bit like mine with a VF48 instead of a Blouch 1.5. I'm still on the stock manifold, but I keep eyeing the gains from a header. I think I'll hold on to my stock piece until I decide if I want to go with a Borg Warner EFR or not.

You know, I've never done a build thread

Thanks, good feedback. It's sorta a build thread, but more just for me to keep track of things and get the name out for the shop that is helping me do the work.

I know most of the guys at Pure, but my buddy Eric has tuned all my cars (in need of a tune) since late '90s. I'm planning to run E85 & set the top end to somewhere 7600-8000 so I upgraded the springs (not doing cams at this point).

For the EWG, I've got a fairly decent sized resonator in the midpipe I'm considering to tie back to at a good angle, or I may just extend the dump tube back so it's past the driver and cap it with a Supertrapp.

As far as turbo's, those EFR's look really tempting, but I told myself I was sticking with the stock turbo for at least the first year (I'll see how disciplined I am).

Thanks for the feedback! Still getting used to the car after spending the past season Autoxing S2k's. I hate the steering feel of the Sti by comparison.

It could also be the S2k has a faster rack than the STi. That'd throw you off on corner entry as you're expecting a certain amount of turning but not getting it. Still, I agree that you should set your angle and then unwind, not set your angle and add more. Seat time will get you there (or a faster steering rack).
