Gas? Fuel? What is it? *EA82T Performance Thread*

My point is that switching from 87 to 93 and not doing anything to the car will not do anything at all except hurt your pocketbook.

I can also see the demand and price for an EA-82T short block from CCR going way up.

In a NA engine, would these two factors combine to reduce gas mileage and engine efficiency?

But when you are trying to get more HP....take for example, a true JDM STi engine...EJ207. By putting the best Jap pump fuel in the tank, you can probalby get 320hp no problem, STOCK. Its rated at 280 from the factory. Here in the usa, the same engine, on the best pump gas we have to offer...it will run like crap, and probably net something like 260 or so. Quite a loss. That is NOT to say that more expensive gas will give you HP...but it give you the capability to extract more power from an engine.
WRXs in Japan run 250 stock, while here, its 227. Not that those two engines are not the same. Cams, heads, ECUs, all are different, to meet US EPA standards, and to cope with the poor fuel we have.
My engine, will run like crap on 93 past 4500, unless I retard the timing way back and then it just wont have any more power past that. On 100 octane, it pulls like a mo fo from 1800-3600...and drops off a little and still pull like crazy to 6k.
I am sure someone can explain better than me the dynamics of octane better than I. All i know, if if you take a stock N/A EA82, and run 87 vs 93, either one will give the same performance. With mods...the 93 will net more power over the 87. Likewise with 100...you'd be running 12:1 compression, race cams, some wild intake and exhaust....
