I ran one last night on the freeway, at the very least it had a can on the back and was very clean. No issues, walked it three times to 120, at one point even letting off at 90 to let him pull up even before getting on it again. Still, I know as a turbo car these things are very capable.

Anyone got any idea what mod levels these are at? You know, basically everyone mods cars the same way, it's just in levels. Intake,down pipe, and exhaust would create this quick of a car, add a boost controller and it goes this fast, etc. etc.

I remember an Evo driver telling me once that it didn't take much in the way of mods to reach around 380 at the crank in their cars. I imagine the STi would be more responsive given it's increased displacement.

 

not sure about levels but I looked into it when i was considering one and its not cheap...35k for the car then 700 bucks for a catback isnt my taste...Evo's arent in "levels"...neither is the str4 neon...Levels are packages that vendors/dodge offer. The evo(9) and sti run damn near 12's stock...a few mods and a tune and low 12's are easy. STI parts seems to be expensive though.

 

Well there is stock and not stock.

 

I didn't know how else to describe it. What I basically meant is what are the basic configurations you can run into?

Like for F-bodies, you run into the basic lid and cat back that have about 15 more horsepower than stock, then you'll find ones with headers putting down about 15 more than that. From there you see the cam guys. Read the sigs of people on here and they all have basically the same stuff, but some are farther along then others.

I figured it's even more like that with an STi because with the turbo aspect you have quick easy horsepower to gain with certain mods.

 

much better off heading to a a evo/sti site...little more involved when you throw fi in the mix.

 

So true lol

 

I had one walk the crap out of me. On the highway. He was in 6th. =/

Here's a local guy's (that stomped me)

Underrated AWD dyno: That's 93 octane at only 18 lbs. He can run 116 octane.

 

Most Subaru owners have been conditioned that you can mod only in stages and that every little mod requires full ECU tuning or the engine will blow up. Seriously, it's that bad. Few of them deviate from the vendor-prescribed path. Of course that's also the most profitable path too...

Others, like myself, ignore the recommendations and mod in a more traditional manner. I was told a manual boost controller would kill my car. That was more than 3 years ago so it must be a slow death. The fact that I datalogged before and after to make sure the change was safe was irrelevant to most -- I didn't follow a "stage" so it means instant engine damage. FWIW, Stage 1 is a tune; Stage 2 adds exhaust (and a different tune), Stage 3 is a bigger turbo (and a different tune) plus whatever else.

Part of the problem stems from the fact that Subarus used to be MAP-based and they didn't adapt as well to mods. After they switched to MAF and a pretty advanced ECU, people still treat them like the old system and assume any extra boost means you'll run lean and blow something. It's not perfect but if my Stealth ran 12.50s with no tuning and Supras run over 500whp with no tuning, both with early 90s technology, I don't see why the Subaru ECU can't handle 20-30 additional hp over stock without self-destructing.

Thankfully for me, there is an excellent open source ECU editor that gives you full control of what's happening. A few easy changes here make the car much more drivable. There's an annoying delay between closed and open loop fueling (for emissions most likely); removing that prevents knock during the transition. Other quickies like remapping the throttle response (drive by wire), bumping up the rev limiter, and ditching the speed limiter are also nice. After that, you have full access to the MAF, timing, knock correction, and other vital tables. Upgrading injectors means a simple change for rough correction and then a bit of fine tuning afterwards to dial it all in.

Then there's the "Subaru tax," where any mod costs 2-3 times what it should. I'm sorry but I refuse to upgrade my top-mount intercooler with a similarly-sized unit for over $700. It's one square foot. It's worth about $300 in my opinion. They were getting $1500+ for a front mount intercooler and now it's down a bit to around $1200 in many cases - at least that adds real performance. Injectors, fuel pumps, etc, are all more expensive than most other makes. Don't get me started on how much more expensive turbos are for Subarus than other makes - even identically-spec'ed units.

Anyway, I've got maybe $700 invested in my car and the assometer says it's about a 13.0 @ 104-105 car. I'm happy with the return but I never would have done it the traditional way which would have cost 3-4 times that easily.

To answer the original question, a Stage 1 STi traps around 105. A full Stage 2 can see 108-109 but that's about the limit of the stock turbo. After that it just depends on how much the owner has done to it.
