300 hp + possible?

ok i gotcha

No amount of money will break the laws of physics. There is only some much oxygen in the atmosphere... therefore only so much power that can be generated from burning that oxygen in a given volume. You need more displacement to get more horsepower (without forcing induction). Given current technology you can expect about 110hp/L with LOTS of research. So you'd need at least 2.7-2.8L just to make 300hp at the crank. At the wheels you'd need at least 3.7L in our AWD systems.

So with gobs of money you could make approx. 230-240 hp at the crank with a 2.2L engine, about the same as the crappy US tune 2.0L WRX engine. I'd go for the boost personally.

You're living within a box then. Did you forget about engine speed (RPM)? Just look to the professional racing industry for examples of this. For that matter, even the little Honda motors are capable of decent power right off the showroom floor. The S2000 made 240HP which even met U.S. emmisions laws too from a 2.0L (now 2.2L).

Like I said, anything is possble with the right amount of money No need to second guess that. The "current technology" can make 300HP. Find someone who wants to do it though $$$$$. Nobody cares enough since a turbo offers the path of least resistence.

I don't think what brat4by4 said was wrong. The s2000 had an enormous budget behind it with some of the smartest engine builders around. They had any test equipment you could dream of and yet the car still barely made 120hp per liter at 8300 RPM! On top of that it only had 153ftlb of torque at 7500 RPM, even a nearly stock ej22t with turbo/intercooler/injectors and tuning can more than DOUBLE that torque.

I think the assertion of 110hp per liter for a normal tuner is about right.

Uh, no, I didn't.

Not to mention if you get anywhere close to the proposed NA hp the engine will be making that power in a 100-200 rpm range or less...

Not sure what guys aren't getting about "anything is possble"? Please don't read anything else into my post other than what I said. With deep pockets, yes most anything is possble including making 300HP on a 2.2L Subaru motor. Keep in mind Formula 1 racing - those cars make 720hp with only 2.4L. That's over 100% increase in power for what you guys are arguing can't be done with a 2.2L There's no reason why any competent race team (or an individual) couldn't develop something like this with a 10-11k rpm.

Tmarcel,
This isn't nasioc! Look at the post count of the people you are arguing with. My point is that most of us here know each other and don't really care to engage in the chest pounding mental masturbation that you see elsewhere. Where this is headed is completely irrelevant to the op's inquiry. If he was a f1 engineer or had deep pockets he wouldn' be posing the question in the first place!!!

If you want to continue down the path of exploring what is required to get an ej22 to 300hp na, start your own thread. If the bickering continues in this guy's thread I will split the crap off for you guys to have it out.

Actually, I'm barely posting these days on any board. I've actually been a bit intriqued with this board since it offers specific Legacy content that isn't availble elsewhere. Don't forget, I also own a BC Legacy

So what's with the post count? I don't get it. I should be submissive or something??? I work in the industry, have built quite a few Subaru motors, and have tuned many cars, etc etc. Post count to me is pretty much non-sense.

As far as the original question, you're right then. It doesn't matter, but what's the point if a curious person can't post a question and have a subject matter expert answer it. I really didn't want to mention F1 because it might shake up a reader, i.e just an example. You really think a Subaru can't be spun past 10k rpms? It's not that hard but again, most of use will never go for the extreme.

Somehow I knew you were going to take my comment the wrong way and get all butthurt. As such, I will reiterate. We are a very tight knit community here and treat each other with mutual respect. Even before my post count comment and your relpy your previous response struck me as unnessecarily defensive and aggressive.That's why I asked you to back off.At no point did I demand you be submissive to the og. I really just asked you to calm down and back off a bit. This thread is over. Pm me if you still don't get it and need to talk about it some more!
