There are other areas of my car that require attention as well, not just in the engine bay. I have a power goal, my driving is backroads and i have plent of them and highway (on ramp, straight line pulls). The extra displacement coupled with the red, meth and tune is the plan.

I do not autocross, street race, or visit dynos.
Large stock location turbos have been looked down upon by some of the larger names because of the restrictions they encounter with intake/inlet sizes when trying to snake them under the IM, as well as the *tiny* hotsides creating too much back pressure. More than enough people have claimed an engine because of that.

along with a 44mm gate of your choice, intake solution (KStech used for your specific application) and some FMIC piping fab (admittedly a downfall in pricing), and you're well under your 3k.

If all you're looking for is 450, the red or HTA green are both viable options, didn't mean to question your research on that front.

I agree with Doc Oc on the non-rotated route. Unless you absolutely need to. You make a point biker on the inlet sizing and restriction on the hot side, but he already knows his goal. I just don't think a WRX is meant to be a highway machine and that what it sounds like we're trying to do. You can do anything for the right price, but its gonna cost ya. A friend of mine bought a Z06 for under 20k and did the basic bolt ons and some cams and is making close to 500whp. That would walk almost anything on the freeway for only a few thousand in mods. Its from a dig our cars shine, but too much power and a stock tranny will ***** the bed. Long story longer, I bought a WRX to build a quick fun car. Its great with a VF-34 on it and makes enough power to beat everything but the built turbo Hondas. Much more power and you are going to need $$$. If you aren't happy where you are at I suggest a different platform. Otherwise my vote is the 2.1 and rotated GT-30R, but it is seriously another 8k easily down the hole without even a transmission.

Rotated is the way to go for anything 400whp ish. You will have an option of better turbos, less restriction, (aka, better spool for more hp, broader powerband), and buying a stock location turbo with all the upgrades compared to buying a rotated kit is about the same.

However, your still going to spend a fortune trying to get that car to any decent power level. It would be a much cheaper to buy a different one, as I stated earlier.

I agree on poor platform, you have a very heavy car with 4wd. If you're just looking for straightline performance you've picked the wrong car. If you wanted a safe, awd, family car with a little bit of pick up, then you have the right car.

Lol, the car weighs about 3000lbs, that's not very heavy at all by modern standards.

For a compact car that you want to go fast in a straight line, it is by the standard of physics. AWD is heavy there is no doubt about that along with increased driveline losses.

So lets get this straight, you want to build a high HP car so you can be a highway speed star and race hondas on public freeways at high speeds

1st off this is moronic and stupid *fast and furious yo*

I would suggest saving your money for the lawyers, tickets/fines, impound, civil suits if you injure somebody else or damage property, and if you are one of those lucky street racers that gets to watch their car get crushed...$ for a new vehicle.

The obvious responsible thoughts aside.....if your goal is to beat a turbo honda then well.....build a turbo honda! They are much cheaper to mod, are pretty reliable, and cheap to replace, and you will be on an equal playing field. It makes no sense either throwing $$$ at your WRX or selling it for an EVO just to say you can beat a honda on a freeway. IMO rediculous!

Now, if you want to accept the fact that being a subaru you have an awesome platform to have a great daily driver, can go to a road course and bang around corners, drive in pretty much any weather or road condition, have great crash and saftey rating (for when you brick your car into the freeway center divider from driving like an asshat), and can fit a small apartment basically with all the room inside (ask me how I know, I've crammed the majority of my apt in mine), then you are on the right course and should keep your Suby.

If you want a fun challange ask your honda racer buddies to a spirited drive in rain/sleet/snow/gravel/loose dirt, and watch them mutter to themselves "Man I wish I had a Subaru"

If your goal is to get into drag racing and you don't have moderate to infinite deep pockets, then IMO you picked the wrong platform. 1st you really need to figure out what your priorities are. If it is simply to throw money at your Suby to beat a honda on the freeway then by all means give me the money you would spend and I will kick you in the nuts....will be the same outcome. Money wasted and a red face.

Ok off my soap box. Before you spend any more $ really think about how much of a priority it is to beat a honda. Im not knocking hondas as I have owned my fair share of them and have enjoyed every minute of them. But you have to realize they are completely different platforms. If you want your suby to act like a honda then I suggest a MPS built motor winding out to 9+k a 6-speed or ppg box and turbo to flow enough throughout the powerband. But being that you are taking about a sub $10k budget I would say either sell everything and go all out turbo honda or be happy with a stout 350-400awhp street machine that is a blast to drive everyday in any condition.

Depends though. Sounds likes he already has the uppipe and downpipe with intercooler. If you go rotated, then you need to buy all that stuff again, plus the new piping for the front mount. Granted you can sell the old stuff, but obviously not for what you paid. If its from the start, then yea you are much better off just going rotated. There was a thing on IWSTI that showed the base cost of all the kits and they typically ran almost 10k with all supporting mods. Obviously he already has stuff like exhaust and injectors, but it will still cost a lot to go from his non-rotated to a rotated setup.

Op wants to roll with 600cc bikes on the highway. Sorry but you have the wrong platform. I've taken down 450whp cars on a lightly modded 600cc bike.

True, rotated now would be a bit spendier, but he could always buy a used rotated kit. The hot pipes and turbo are pretty cheap (a airwerks is something like 600 bucks), the intercooler piping would be a bit of a pain, but still not bad.

What we should be asking is if your losing to 10 sec Honda cars (your screwed) or old school turbo civics that run a 13 sec 1/4. If you want a 10 sec car, you could invest about 40k into your wrx and it might be sorta reliable, or you could buy a better platform. Hell, making your car into an 11 sec vehicle would require at least 15k and still won't be very reliable. It would be far cheaper buying a new (09 plus) WRX or STI and doing that. Ideally you would buy a muscle car or an evo (an evo 9 will be in the 11s with bolt ons and E85....).

If you want to be modern 600cc motorbikes you have to have a low 10 sec car. So, highly modded anything (FI Z06, boosted mustang gt) or you could prolly do basic mods to a Shelby 500, Camero ZL1, Corevette ZL1 (and those would be reliable!!!). You could go old school too, drop a LS7 into whatever your lil heart desires. Better yet twin turbo it, tub it, and run 8s.

Basically, your trying to play with the big boys in one if the worst possible cars available to do it. If you truly want a 10sec beast, you have to buy a better platform.

Like people are saying. If you want power and speed, definitely Z06, Supra, Mustang, 911 Turbo, GTR... etc.

I love Subies and EVOs, but they were never intended for serious power and speed.

One day I plan on a 993 GT2 Evolution build

Agreeing with Rexblake. A WRX is good if you want a 12 second car. Anything beyond that starts to print money. Buy one to make a car that will take 90% of the stuff on the road. If you want real power, you pay for it. A big gas guzzling V8 will make power a lot easier than a 4 cylinder. I believe in replacement for displacement is boost, but when you are already running 20+ pounds its tough. A V8 with 10lbs of boost will pretty much always beat a 4 cylinder making 20.

Tomei 7760 and ELH on 91 pump (with the proper supporting mods) will get you 325whp on the EJ205. However on e85 you're looking 400+whp.
