What is the simplest way to make 350HP on 2007 Subaru WRX Impreza? Ok here is my question I'd like to make 350 horse power on this car, it',s the reqular not sti edition. I heard their stock engine can handle up to 450 horse power without mods. But what is the simplest way to make this much power and the cheapest. I don',t know a lot about turboed cars or subarus only that they're great cars so any information will be appreaciated. I'm trying to break in to twelve sec quarter mile times. Thanks.

350 at the crank? So about 120 more than stock? Pretty easy. A full turbo back exhaust, intake and a tune will get you pretty close. Add a VF22 and a fuel pump and should get you there, most likely more. If you're talking power to the wheels, you'll need something closer to a 20G, higher flowing injectors and the other behind mods. I think since it',s evident you'll have the work and tuning done, you may want to be talking to a tuner about how to reach your objectives although. you'll get much better answers.



Aaron. What the hell is a G14 turbo and why could you install pinks when the 06 and up WRX injectors flow 560cc? And pinks aren't enough fuel to make over 400hp so I guess I just called your BS. Go troll someplace else.

The stock fly wheel should be kept for drag racing, the lightened flywheel will increase your 60ft time since with less rotating mass the engine rpms will drop more which you'll loose increase. For that kind of power you could be looking at Turbo back exhaust, Turbo, Fuel injectors, bigger intercooler, Aftermarket programming, and soon after that most likely Pistons and Transmission. You could most likely forgo the intercooler by going with water injection from a company like snow performance.

i have an 07 wrx and I',m to get around 420. I ran a invidia n1 cat back and bell mouth down pipe, I also but pink sti injectors in it with a g14 turbo, cold air intake and a good tune. it's important that you get bigger injectors if you want to have more power and you'll have to get a stage two or three clutch if your going to run over 280hp. i',m running about 11.8 on the 1/4..good luck, hope this helps

removing 100lbs from the car will give you a 10th of a second in a quarter mile. brighten the rotational mass on the crank like a aluminum flywheel and a pulley set. a down pipe with a cat back and a good ecu tune may break you into the 12"s

Trade it in for an STi and slap a bigger turbo on that's most likely "the simplest way" and really the cheapest way too.

It depends what you mean by "easy". I',m thinking an STi exchange with a Cobb stage two package but that means a new ECU, exhaust, turbo, motor of course and the time + money.

racing stripes and a really big rear spoiler. both add 175 hp each. guaranteed ten second quarter mile.

First of all, you don',t need 350 HP to run a twelve second quarter. if you',re looking more for the 1/4 time, don',t concentrate on HP. I have about 295 HP in my WRX and I',ve ran a 13.03 as my fastest time. That pissed me off, SO close to a twelve haha, but oh well. So just I',m saying you don',t need that much HP to be that fast. So concentrate on one or the other. A car can have a bunch of HP, but that doesn',t essentially mean its that fast, case in point

the 2010 SS camaro, 426 hp, 1/4 mile time 13.0

the 2009 WRX, 265 hp, 13.5 1/4 mile time

the WRX posted a barely slower time with 161 less hp,





However, it',s not too hard to get that much HP on a WRX. I',d say turbo back exhaust, catless down pipe, up pipe, mid pipe, Intake, new turbo, say a 20G, and a tune should do the trick.



I',ve seen a man run a ten second with a WRX motor, but I don',t know his HP numbers, so its possible to at least post that fast with the motor.



But also remember suspension mods. Subarus are at their best going around corners, not straight line racing. I believe, it doesn',t matter how fast you're if you may be able to only go straight.



Good Luck
