I'll address your points one by one.

1. It's not impossible, but it will be very expensive to get 220 hp out of a  NA Subie.

2. I didn't say the compression can't be raised. I said it can't be raised MUCH. And static means nothing. Dynamic is what I'm talking. Remove some combustion chamber volume, it goes up. Add lift and duration and it comes back down. Dynamically, I'll bet the stock and super-modified engines are pretty close. That is how I'm running 10.2:1 static in a 2165cc aircooled engine on 93/10 on the street.

3. 10% of 165hp is 16.5, or in the vicinity of where Lane's car is. Yes, 10% isn't that hard. It's when you're looking for 20% or 30% or even 33%(55 + 165 = 220) that I start to get doubtful. A 1/3 power increase on an already very well-tuned NA car is not impossible, it's just improbable.

4. An aftermarket ECU is indeed the key, as are intake, cam, head, and exhaust mods. All of them together, there is no free lunch and/or one bolt-on item that will give you 1/3 more. It's just expertise and MONEY.

Show me the dyno sheet, with all parameters listed(baro, humidity, correction factors) and with both HP and torque curves, like my man Stan says. Otherwise, it's just conjecture.

True statements Danny, EJ Engines range of Hp and torque ... say the stock ECU gives you 165 to 170hp if you tuned the stock ECU with a custom tune and had better exhaust headers and better flow air intake ie K&N you might get 2-5hp extra, maybe in California that would translate to 10hp more ... could be achieved.
