    No matter how much you tune the engine, you will experience detonation running too much boost with too high of static compression unless you change fuels. This is another mod. If you could run unlimited boost and unlimited compression everyone just would. Something has to give. BUT, if you change fuel to allow more boost, it stands to reason you need to change fuel for the 2.5 as well to remain a parallel comparison. So hell yeah I can say it. More compression, less boost. To surpass the 2.5, you have to increase boost but to do so it requires modifications that make it no longer "apples and apples".

    Unless the 2.0 gets modifications that the 2.5 does not receive, the 2.5 will keep putting out more power.

    How is the 2015 WRX STI? is it worth getting

    I'm not following the discussion. Doesn't make sense to me....maybe I'm not understanding it but the EVO had a 2.0 and mod for mod it makes more power then an sti.....as far as I know. Maybe he means it will make more torque...

    This video has been referenced many times in this type of discussion. Important info relevant to this topics starts at 2:24

    "This particular engine is much stronger than the EJ motor. Really likes to make power. The same turbo we put on this engine, on an STI we can make like 360hp, on this motor it made 430hp. Same turbo, smaller motor. The FA motor really likes to make power"

    When you have people like Crawford saying things like that you might want to take notice.

    We were talking the viability of one vehicle vs another for modification purposes. You can't do something to one and not the other. We're not discussing the cheaper method to end up at the result. You can't match the output of the bigger engine without modifying it. You can go ahead and spend the $10,000 vehicle purchase difference on engine parts for the 2.0 and I'm sure it will stomp the stock 2.5. But we're not discussing a horsepower output difference, we're talking about the viability of one vehicle vs another for the purposes of modification.

    Great, you're stoked for your 2.0-litre, and you can modify it to beat a stock STi. Be honest, the $8k price difference between vehicles will get eaten up pretty damn fast when you equip that WRX to be equivallent. You can't really think that you can SURPASS the STi without modifying it, but when you drop that budget into the WRX the same budget will make the original STi exceed your modified WRX.

    SO again, it's a chicken and the egg comparison. HOWEVER, you get more to start with from a base STi than a base WRX so despite your engine technologies, PLATFORM really refers to the vehicle as a whole. You can swap the 2.5 into the WRX and the 2.0 into the STi and the STi wins all day long(if what you claim is true). But despite your "superior" engine (as you call it) the platform is still less capable.

    Now you are circling. Define "platform?" The chassis between the two cars is the same, so if you're discussing swapping engines, transmissions, etc, wouldn't the better platform be the cheaper of the two??

    Also, as others have mentioned, mod for mod the FA20 makes more power. How are you not understanding this??
