06 sti story

Almost from the get go of owning my sti I started modding the vehicle. Got my sti when I was 18, now I am 22. Was stage2 for a long time:
k&n intake, turbo back exhaust and ecutek tune. Made 315whp/320wtq on dynojet.

This is alot of power, especially if your not used to a 300whp car. A ton of fun, and I must say that inexperienced drivers should consider this being the extent of modifications unless you have some heavy capital to invest. I was lucky to have excess funds available to even do these modifications at the time.

Stage 2 with a good tune can run up to $2,000.

So at 50k miles I was given the opportunity by someone at the local subaru dealership, and it was a pretty good package deal.

sz49 turbine pnp
turbo xs fmic
invidia up pipe w/ tial 44 ewg
APS intake

I purchased some additional mods ontop of this

So my list of mods became:
grimmspeed ported intake manifold
grimmspeed tgv deletes
grimmspeed ebcs
grimmspeed ported exhaust manifold w/ high flow crosspipe
grimmspeed aos
invidia 3" catless dp
invidia g200 catback exhaust
invidia uppipe w/ 44mm tial ewg
sz49 pnp turbine
turbo xs fmic
tial q 50mm bov
APS intake
750cc inject

Act heavy duty pressure plate / street flywheel/ 6puck

easily a 400whp/400wtq build on a dynojet w/ 93 octane.

tuned in @ 370whp/375wtq 16psi

What I didn't do because of the excess labor and time was replace my pistons or do any motor work at all. In short the motor didn't go long without problems, the car ran but used excessive amounts of oil in short periods of time.

Luckily I had gauges to check my oil pressure to keep my motor from dying but something was definitely wrong, and oil changes every 4 weeks was becoming repetitive. Boost/Oil Pressure/Water Temp gauges are a must if you begin modifying your vehicle heavily.

If you are going to mod your STI to be 400whp with a stock bottom be ready to replace the motor at anytime. If you have the funds available to put into the motor do it for reliability. You will save time and money, as now I am getting a new motor with forged/coated pistons, now and have been out of a vehicle for about 2 months.

Another thing you should consider is using a TMIC over a FMIC, for goals of 400whp and below a FMIC is not necessary. It looks cool, but it removes your front bumper beam on most FMIC applications. I regret moving to FMIC at this point and plan to go back once I can find a replacement bumper beam for cheap.

Thanks for the story and first hand experience of upgrading near 400 whp without doing internals. I've got a pile of parts waiting to be put on that I'm planning on tuning to only 350 whp but can probably get more out of it. Reading your post I now know to just stop at 350. I thought about tuning to go above 350 but not 400 and now I'll make sure to roof it at 350.

Exactly, on a high reading dyno. Realistically you're making that 370/375 on the regular 93 map.

I'm a bit new to the Subaru culture, but I completely agree with the article. Taking your time and thinking out your mods is always a good idea

I actually decided for a TMIC just because I don't want to lose crash protection. And you all know that if we are going to crash ina 350HP plus engine, its going to be head on!

I remember when i first got my Subaru i thought 400hp wioll be super easy to get. It takes alot of planning and time spent under the hood. So before you role with the big boys, you need to start from the bottom.

This thread was an incredibly informative read, especially with OP's very well written, insightful, and intelligent post.

The "sometimes less is more" mantra here reminds me a lot of motorcycle riding, which I actually started and got a license for before even a car license. I made the huge mistake of being a squiddly teenage rider and buying a new super sport bike and paying for it with blood and broken bones like every other tard who starts off on one (Rider's curse, you've either gone down or you're gonna). Even worse was the fact that despite the universal teenage invulnerability that every speed loving, red blooded young individual goes through in their lives, I got burned out relatively quick by the fact that even a 600cc sport bike is just too fast and high strung to putt putt around for daily use (which I did for 5 years).

This point was driven home even further when I got to borrow bikes from other rider friends for extended periods (in return for garage space at the time), one who had a much more practical upright naked Suzuki SV-650 and another who had a Ninja 250. That 250 especially was a blast, as it didn't stress me the hell out if I wanted to take a quick ride and enjoy a particularly nice day or go to the grocery store to pick something up. Anyone who's a serious or experienced rider on a super sport knows it takes a great deal of maturity (even at immature ages) to handle your crotch rocket otherwise she'll be punishing you without mercy.

TL;DR - If I were to ever buy a bike again, I'd get a docile upright that I can actually enjoy every day first and then add the super sport. Never going to own a sport bike on its own. Cars should be the same way.

i agree
i cannot tell you how many times i have had to " turn down" a project the someone comissioned and wanted "max power"
the toyo fj with the bbc and a turbo comes to mind, i thougt it drove nice, very linear power, ran straight , etc, i guess roasting the tires at 60 during a passing manuver was to much lol

I will say I bought my wife a WRX mainly because I'd become accustomed to the power in my 07 C2 Turbo VW Rabbit which is currently chasing the stock internals record on water meth though its probably like if they put the STi's motor into a FWD car. I wanted the power but I wanted OEM reliability and AWD. Thus save a boost gauge my WRX will be stock for years to come.

After looking at my post back in April '10, I have to admit that this couldn't be any more true! After having been without that power for several months, I've started to appreciate how much nicer it is to drive a car with suspension mods and just a tad bit more power than stock.

Having a nimble car is so much better now, than having a car that pulled you all over the road.

I couldnt agree more, I came from an 1985 rx7 with in my mind a pretty decent amount of suspension work and that car was a absolute BLAST to drive. I then got an 08 350z which I HATED that thing was such a fat pig. Now that I have the '11 WRX, I cant wait to do some suspension upgrades, im sure its going to be one hell of a car!

Im curious what you found to be the cause of your oil usage issues. I ran a stage 2.5 +- at about 285 awhp for 30 k mi (09 WRX) then slowly had increasing oil consumption. Ended up blowing a head gasket at 37K mi. Just had engine rebuilt, had to mill heads and increase bore to 100mm and dropped in some Mahle forged pistons and ARP head studs. Im on the same tune now and it runs great, but Im not convinced that forged pistons are going to give me any more insurance against the problems I had before. Good for a detonation buffer with bad gas, but other than that not sure. Shop thought that the stock head studs werent torqued down properly or maybe they stretched. Anyway, it was a fisting of an expense but i wouldnt want this car with any lower power level and would like a bit more for more highway roll on pull.

I guess I will have to add to this thread. I only read the first two pages and kinda skipped to page 31. I am coming from a wrangler on 35's where my top speed was 60 mph, granted I didn't have doors on it. I am completely happy with my 2008 wrx hatch. The first drive home I went around an 18 wheeler and looked down at the speedo... I was doing 110. WTF!?

In all honesty, though I am using this as a commuter car for the next six months, then when school starts backup it will be a weekend car. I would like 300 hp, if possible vf52 turbo at the most if I get bored. I am new to the subie world though, this awd is funner then when I used to steal (borrow) my mom's audi TT, when she was out of town. That car was fun, but really complained when driven hard.

Anyways, no real point to this post. I still remember learning to drive stick on my dad's '64 chevelle with a worked 454 in it on the backroads of Tennessee. Haha, I learned how to feather the clutch real quick after the first time trying to take off from a stop sign.

I "borrowed" my Dads 442 W-30 at age 14.

PRO-TIP do NOT leave posi black marks in front of your driveway when your Dad comes home from work.

Anything less than 500lb/ft and I am bored.

I suppose I am like a girl who gets her virginity taken by a huge ****. anything less and I am disappointed. .

I can relate. I'm a huge sport bike fanatic, owned a ZX-10 for a couple of years. Having 170HP on something that weighed 430lbs with a full tank of gas will permantely change your definition of "fast". First time I took it to the drag strip, my best was a 10.3 @149mph. Besides a slip on muffler (Without a tune at that...), it was completely stock. 100mph? Yep, in first gear. 5 more to go. Wanna wheelie at 115mph? Sure thing, clutch it up in 3rd gear, no problem.

As much as I'd love to have a 500whp STi, the logistics alone stop me. It'd cost me $10-14k in parts alone, that's assuming I did all the labor (Prior ASE mechanic). I've been there, done that, played the modded vehicle game; I used to be real heavy into modding Jeeps.

I'm more than aware of the simple fact: Cheap, fast, reliable. Pick 2 of the three. Can't have it all.
