Alright guys, I have a 2004 wrx wagon. I would like to hit 450 awhp while spending around $3000. The only thing done to the car when i bought it (last week) is a turbo back b&m exhaust and a bov. I plan on getting:
Cobb access port
650cc top feed injectors
Cosworth cams
Turbosmart ebc
Hard ic piping
Titanium valve springs and retainers (haven't decided what brand)
and also a bigger turbo

Honestly I have no idea what turbos work well on an ej20 (im a dsmer at heart, sorry). I dont want to wait forever to spool, but I also want something that will last me, and whats a good exhaust manifold. Please give me your opinion, I'm a quick learner and will catch on to the Subbie world very quickly.

BTW, I was just doing a little research and i realized that my wagon comes stock with a Mitsubishi td04 t13 (also known as the t-too small)... this is the piece of crap turbo that comes on the 2g DSMs that doesn't hold boost. This absolutely HAS to be replaced. Any suggestions?

You will most def need to do your bottom end as well (Pistons & Rods)

Skip the Accessport and either do open source or get a standalone at that point.

You will DEF need larger injectors than 650 CC especially on the factory rail.

What profile camshaft are you planning on getting?

For 450 power range, you can either go rotated or look at the AMR Turbochargers if you're not planning on going with an external wastegate setup.

I'm not sure if you can hit 450 AWHP without needing to switching to speed density air metering setup or not.

PM me because this won't be something that you will only spend 3k on to be honest with you.

How'd you decide on that number, dartboard? You'll need deeper pockets to do it the right way and keep ot on the road... BTW an AP is only going to limit you as far as power potental as you'd need a protune to not be limited to Cobb's format... Also you'll need at least 3k alone just in suspention mods at that level...

It's a rock solid unit that typically causes absolutely zero issues...

that comes on the 2g DSMs that doesn't hold boost.
Are you possibly thinking of the T25? That too was a small turbo, and they were correct to replace the 14B with it as it was better suited for a road car. Ford did the same with the Escort - went smaller. Anyway...

This absolutely HAS to be replaced. Any suggestions?
Your power goal, although arbitrary, is unlikely IMO to be compatible with your stated budget. Look into a hybrid build plus.

The cost of the motor build to support 450whp alone will exceed your $3000 budget.

If you're not willing to drop $10-15K, forget 450whp.

Once you're at the 450whp mark, have an additional $5K sitting in the bank for when (not if) things break...

As 06scoobywrx said, your budget is already blown on suspension to support that power (coilovers, larger sways, endlinks, stronger control rods, urethane bushings, subframe bracing, etc). I would also add that a big brake package is mandatory at that power level (which in turn requires larger wheels and tires over your stock wheels). You would easily spend more than $6k on just that alone.

Now, your stock transmission won't last long under that much torque stress, so plan on replacing that (probably with an STI unit).

Still reading? Ok, now onto clutches...

Not trying to be a downer here, but no one on this forum wants to destroy their car, and we don't want you to either (or far worse, endanger yourself and others). Go ahead and make huge power, but please ensure the rest of your car can safely handle it.

HAHHAHAAHAHAHAHAHAHAAA

As said, what you want is NOT possible for that little. Granted, for 3k in mods you can have a really solid and fun car.. but not anywhere near 450awhp.

put it this way, stageII (down pipe and cobb access port) will run you a little over a grand. See how quickly the budget starts to disappear? .. Its pretty easy to get to 300awhp with $3K, but beyond that is where things start to get very expensive very quickly.

Not only that but if this is your daily driver you're never going to need or use that much power on the street. Ever.

Lastly, have you driven a 300awhp car? They're wicked, and still mellow enough for nice smooth daily driver work.

Ok now I have somewhere to start. This is not going to be a dd, just a fun project car. Let's say the three grand is just to get started. The only thing performance wise done is the turbo back 3" exhaust. Where should I go from here. I'm now setting the FIRST benchmark at 300 wheel.

Yes I have driven several cars that are over 300awhp. My 1g talon awd is right around 300, my buddy's SRT4 was 580, but that of course is fwd and was on slicks, and I've also driven my boss's 2010 gtr.
