Step 1: -Moroso Oil pick up tube -Killer B Windage Tray -IAG/ Perrin Air Oil Seperator -Cobb Accessport. -#4 Cylinder coolant line upgrade. Step 2: -Downpipe, -fuel pump -intercooler Step 3 Pro tune.

I'm pretty sure if you get air fresheners, each one give like 15hp

Although the power gains are minimal, what you've said is realistic and that is really useful for someone who wants to start getting more power. Great video.

Dude, I had a 2009 wrx hatchback which was rated at 265bhp. I miss it so much! Watching your video made me reminisce. It seems like the turbo on your`s spools up much faster, specially on the first pull you did in movement. Really nice, grats on the car and mods.

That Cobb BOV reminds me of my Tial BOV on my Civic. I have wanted to get a WRX since they first came out, but never got the chance to get my hands on one. I have always been a Honda guy since I was 18 and bought an older Integra (back in 2001). I bought a 97 Civic for $1k back in 2014 and boosted the VTEC single cam that was in it and it would hang with modified WRXs. Now though, it has a built forged LSVTEC turbo in it and so far I was able to make 508 whp on my current setup, and still have room for more. Yes, it is still FWD, but with the LSD that I put in the trans it grabs and goes. Regardless of what I am into, I still always show love to other people's builds no matter what brand it is because they put their heart and soul into it and that's what matters to me. Awesome build brother.

Thank you for using the correct term AFTERFIRE. There are so many people that keep calling the pop from the exhaust BACKFIRE.

Stickers and blow off valve

Want to know what to do??? Downpipe, injectors, fuel pump, e85 tune... thats is the easiest most reliable way to get 300 imo

7:03-7:09 = 0-60 in close to 6 seconds I know that factory intercooler was probably heat soaked but a 300hp wrx should be in the 4's 0-60... considering the stock ones can run it in 5 flat. Get a fmic, air oil separator, and a real tune... then you'll be closer to 300hp, your 0-60 will reflect it at that point.

So many people use stage 2 with either an intake or catless and then complain when they have problems. If you are using an OTS tune be sure to use the right parts!

Get yourself a lightweight crank pulley. I have basically the same mods on my car. I can say that after installing the lightweight crank pulley the car feels like a whole new animal.

On a wrx I would NOT upgrade the clutch, unless the trans is strengthened. There needs to be some slip in the system when driving hard, especially since common aftermarket mods increase torque (like Cobb Stage 1, 2). Torque is what kills drivelines Since it’s AWD, tires won’t slip like in 2WD. So that leaves either the clutch, or all other driveline components. I’d rather have the clutch slip than an axle snap or have my trans explode lol

I just bought my 05 WRX Sedan about a week ago, has 39K miles, and the only mods that it has are an SPT intake and an AVO bov. I just wanna get it over 300 hp right now and then ill probably sit there for a while & do some cosmetic upgrades.

COBB SF INTAKE ,,,, i swear i saw the AEM intake under the hood there

My 2002 Subaru wrx wagon stage 2+ using cobb sf intake/aftermarket boost controller with pro tune made( @ 16-17PSI) 210WHP & 218torque on a all-wheel drive dyno that 300HP must be the crank number!

Might have been said before, but the exhaust is Invidia, not Nvidia. Sorry to sound picky, just so people know if they want to research where to buy them.

Kinda odd they nerfed the stock boost on the STI. Just get a tune and you'll make the 300 HP easy.

Ya i call bs. Even if your "tuner" was giving you crank hp number based on some very generous conversion formula there is no way your tiny turbo could make that power with the stock intercooler on pump gas. Cobb says that a typical 2008 will make about 20% more whp on stage 2 so you're looking at 220-230 whp max so like 250-260 crank hp max. There is a reason why 2009-2014's are in such higher demand than 2008's.

yup, my '08 GT500 was 500 hp OEM then , 160f thermostat, carbon fiber 140mm CAI, L&M 72 mm throttle body, tune, mix well 650tq 630ish hp supporting suspension parts, SVT exhaust(borla) race car with plates.....will drink 30 gallons of fuel an hr....oB

Had my 2002 wrx since 2011 and since then I have a built ej257 and ra gears. I invested quiet a bit of money on this car but at the end of the day I love waking up in the morning.

If you want a reliable WRX I would not recommend going past Stage 1 Personally I own a 2009 Impreza WRX with, Cobb Accessport (Stage 1, 93 Octane) Cobb SF Intake Invidia Q300 Exhaust Lighter Aftermarket Wheels (6lbs less per wheel) Dyno read 285+ WHP Meaning 350+ at the Crank I have some cosmetic things like a Cobb Shift Knob, front lip, and vortex generator however nothing I’ve done isn’t tasteful

I don't know man... you're not convincing... anyone? You sound like the guy who blows his engine.

I could never take advice from someone who leaves his hand on the stick when he’s driving...

Great shit! Thanks for the break down and doing all those pulls for the viewers homie nice car

That Boxer Exhaust note just cant be beat!

Bov dosent do anything except sound like unicorn farts lol

I’m going to have this set up with headers/uppipe and grimspeed intercooler. I’m excited after seeing your numbers.

"Invidia 3" Down Pipe Invidia High-Flow Cat Invidia Turbo Back Exhaust" The down pipe and cat are part of the TBE...

RED FLOOR LIGHTS, MOD LEVEL OVER 9000!!!!!

Thanks for the video man!!! I got a LGT I'm looking to get around the 300WHP range. Nice to know with some simple BPU parts and tune I can get close to that without tearing into the motor and still using the stock turbo.

Put it on a dyno, and come back with the charts backing up your claims. Otherwise go with what the respective bolt on claims are, which is 20% gain as mentioned by others ...

Cold air intake, straight pipe and tune might get you +15hp if you're lucky

stop resting your hand on the gear shifter

I have the almost exact same modz stage 2 protuned and im not even close to 300 hp. I have a 14' hatch and it dynos about 250 to the wheels. IDK were this guy got 300hp + even if i was e85 which im not i still dont think ill hit 315 hp..would be around 300 ish i think

I have a 2005 wrx that I just bauhht stock with 120,000 miles I just started my journey of building and I just bauhht a intake and acces port

I have a 2005 Saab 9-2x aero which is a WRX with different body panels, a better suspension and a quieter exhaust, if it wasn't for the hail damage it would be like new because I rebuilt the engine at 90k miles so it's like new.

i have the same setup on my 07 sti, dynoed on a dynapak, got 323hp and torque 340

I have been getting lots of questions and messages, I will be able to reply a lot quicker on Twitter - @SubaruWRXRacing

@subaruwrxracing hey, I have almost the exact same mods (minus the Cobb cai, I'm running aem)!! my next purchase is probably going to be a catted dp and a pro tune. but its nice to see a fellow narrow body out there!!

Why did they make this car look like a toyota corolla?

If it was me, I would buy an sti, get Catless TB exhaust, fuel pump, 3 port boost solenoid then a tune and at that point im sure you would have similar power but you dont need to worry about injectors, intake, clutch and you have a super strong 6 speed also with better suspension and stronger engine however if your talking about 2008 wrx vs sti it could be a big money difference. I have a V7 Sti and im so glad I didnt get a wrx but like I said, the 2008 sti would be a lot more than the wrx so thats a big factor I guess. Nice build tho, 315hp for wrx is pretty good, the Turbo must pretty maxed out tho.

love to see dyno spec numbers, 09 wrx stage two pro tune here.

Just add stickers it will make it faster It will make any car faster

How to more power easier. Sell your 08 WRX for an 09+ WRX.

Perhaps an automatic trans swap is in the works? Looks like it would suit you better lol

You lost me at "load the stage two mod" that "overrides" the ECU.

315bhp on a TD04...... Doesn't sound right.

i have an 08 wrx and am making 320 awhp 370 lb ft tq. vf 52 turbo though that td04 is unreliable. Im surprised that little tiny intercooler doesn't get heatsoak.

i would smoke wrx all day in my little 1.8t jetta that thing would hit 90 on 3rd gear spooled way quicker than a wrx turbo but sadly i had to sell it to get wrx for some fun but mostly real use in these hard winter times

That BOV sounds amazing

Save your $$ for the upcoming head gasket repair.

what i liked about your build = safe power, new clutch what i would of done differently = save up 3-4k and then buy everything at once, in the end get a professional tune, access ports suck, every car is different and you might be fucking yourself and you dont even no it, leave cpu n shit like that to pro's and a well known tuner x.x Full exhaust, a real cold air intake, fuel injectors, fuel pump, and tune with e85 probably 300 whp for 2k instead of 315 CHP for 3-4k hopefully he switched out the tune to a pro tune im scared for him if he gets ring land failure and i dont even own the car x.x nice setup tho :)

Your car sounds amazing I want it lol I prefer the 2006 sti but your one sounds awesome

That high rpms launch tho haha

315 hp at the crank or wheels?

many people have complained about a throw out bearing issue with the clutch... what are your thoughts on this?

You can't get that much power from a td04 with just a downpipe and blow off valve, not even with the vf52 your at 300 whp maybe 315 to the crank

why does it seem slow 0-60 looked like 5 or 6 sec

I will definitely be trying this!!!

It’s a bummer that Cobb doesn’t offer the stage 2 for the 04 wrx

"cheap"... this video is just telling you to go buy a cobb stage 2+ kit.. oh no thats $2500+... Im sorry, but if you want cheap power a $200 ebay TBE, $60 ebay intake, make your own intake box, make a turbo heatshield, or get a blanket(30-60), get a tactrix cable $169, 3 port ebcs by tactrix for $100, and go street tune. a nice sub $600 mod list that will last, and produce the same amount of power...

Dude, if your stock setup was pushing 12.5 psi you had a boost leak. Stock turbo tapers at 15.5. And that's on a stock tune

Watching the speedo my 02 wrx with just the ap pulls harder and faster acceleration

How did you go with all mods? Did your engine or gearbox had any issues at all? If not I am impressed!

Bro really, 315whp on a tdo4 and stock intercooler? 🤔

I would pass on the bigger intercooler at your mod level. I did the bigger intercooler mod and my track times didn't improve. So to me it was a waste of money. The stock intercooler was working fine and I felt like I just threw money away. The best mod is to upgrade the stock turbo. That will make a significant performance gain.

How not to drive: Check; Buddy spend some cash on driving lessons.

I have a 2010 forester XT with the same exact engine I believe

I might be buying one tmrw, I feel very pressured. Seems like people care a lot about how you drive and it’s a subie so it gets a lot of hate. I am nervous also because I don’t know a lot. I am very excited and eager to learn about the engine and all that. Anybody have tips. I really want to know more. Any places I can learn? Thanks

I'm a former 08 wrx owner... The 2.5 with 227hp. So all those mods which aren't much brought u up that much huh?? I got a 2017 now and so far my mods are injen intake access port stage one (no exhaust yet) and winter tires. Wondering what kinda hp I'll be sitting at when I get downpipe turbo back and possibly fmic. I'm down the road wanting to either get a crate motor from Crawford 400+ hp as a daily driver. Or deciding if I wanna mod my way there. Anyway man good job and good luck with the narrow body. I remember the suspension sucked balls in that year. Any plans on suspension mod? I love the new gen suspension. Freaking incredible

wheres the dyno sheet

realistically this car is running more like 240-250 at the wheels. td04 and OTS map is certainly not capable of 300 to the wheels.

So you're saying your 08 WRX is making more hp than my 11 STI which is running stage 2? I am confused 🤦‍♂️

Please learn how to shift / drive

have you upgraded anything since this video... I have a stock 08 hatch 4 years now and its depressing lol I hope to get the access port with intake soon... that would be a start... I like your video is on a budget build... I do have a 12 pound flywheel I put in my self!

That 5speed only has an estimated half a dozen good launches before she goes

Ive got the same setup as the description except the injectors and i assume it is under 300hp by the way it pulls, do you have the claimed hp numbers proven?

Was thinking about getting a bugeye but after watching this video I think the only "mod" I want to do is not become a "subie bro"

Just put a wing and an Sti decal. Then people will think you got 305 horsepower

I hear/read all the horror stories of Subie blocks cracking before any mods..I still love Subaru and would love to scoop a 2005 WRX STi, if I did..would going built first before a stage 2 Cobb kit be the way to go? Brian Crower Stroker kit then have the block machined and kit installed prevent a blown motor crisis? I know Subarus cost sooo much to build for hp but man those 05's are sexy af.

Get E85 like I did. I had the same numbers before flex fuel. Look at my dyno vid to see what corn does! LOL

Hey there! My 2008 WRX is in the shop right now undergoing a stage 2 upgrade with full invidia TBE and cold air intake (+ tune). What's the noise like from this exhaust? I don't overly love loud cars so was trying to avoid anything obnoxious just purry, and subtle.

Am I stupid or is does the invidia downpipe already have a high flow cat? Why are you saying it desperately like it’s two different things?

nice 2008 subaru turbo 300hp pulll

For the lainch cotrol you woud need the power asjusted going to the rear diff!!

4:31 in the video, the car chirps the tires and jumps 1000rpm in a split second :o

Dude this is nice

I just got my 2016 sti I wanted to know where can I get good deals on Cobb acess port and cobb intake and cobb bypass valve . I have the axle back nameless exhuast I also need the mid pipe but don't want to spend the 600 for it from nameless .

Is that where the light shows up when you turn traction off? I have a 2011 and that is where my light shows up (same as on your dash) My friend has a 2013 and when he turns traction OFF, his light shows up right underneath 8k rpm mark on his RPM gauge. Just wanted to know if this is normal thank!!

NICE! can i ask if you've had any issues since you went stage 2? w/all the mods you did.

I have on 05 wrx and went stage 2 about a month back. I was hitting about -2.11 fine knock learn at throttle changes and ~-4.22 feeback knock sometimes. Last week I was hitting positive .7 fine knock. I switched to the ACN stage 2 91 tune and am still getting ~-2.11 feeback knock. Are you having the same problem? My plan is to do uppipe, Cobb sf intake

DISCLAIMER!! this does not cover your blown head gaskets long term, thank you!

Sweet ride

I have a question I have a 2001standard wrx and my first gear isn't getting enough gas what could it be?

Flashing a new map doesn't override the ecu, it completely replaces it...

Are you protuned? I make 342whp/362 trq 650 dw injectors ebay top mount intercooler 3 in catless 2 inch up pipe 340 aem 3 port ebcs protune 91 octane

I want to get like 2002 wrx and I need it to run faster than a 2005 mustang gt. What should I do to it and how much will it cost to make it a low 13s car

Hello i just recently baught a 18 wrx. I am going to tune it in the futer. Was wondering whats the smartest way to get around 300 hp. Im not trying to do to much to it jjst make it around the same hp as an sti. If anyone could inform me id apreciate it thanks.

4:30 did u clutch kick it... I'm putting in a new clutch in a few weekends. have not made the decision on the stage 2 yet. have you run into firewall spot weld issues? any clicking when u push the clutch in?

Why do you keep going from 3rd to 4th then back to 3rd then back to 4th when your at the exact same speed
