so if most pistons are aluminum, then why would the Yaris pistons be any different than any other "fragile" aluminum piston when it is leaned out. If that were the case the the 2g eclipse's "fragile" aluminum pstons shouldn't have held up, correct?

and with the exhaust manifold being tubular steel, it would fail -way- before the pistons ever did.

have you ever seen a 1nzfe piston in person? 1nzfe connecting rod? no? i have. they're fragile, under-engineered.

this still does not account for the fact that a DSM is gonna get great gas mileage because of the turbo, and a 1nzfe is NOT going to gain fuel efficiency by leaning the engine out excessively.


do me a favor


go drive your yaris around at 19:1 AFR for the sake of the almighty fuel mileage and see how long your engine lasts

again, I don't tear apart my pos yaris that I drive to work every day to make it a race car, so no. I don't know what the internals look like.

then again, I don't expect a yaris to be an autocross or drag racing machine.

pot calling the kettle black, you want to lean out a high-compression N/A engine for the sake of fuel milege, because "some guy with a 1993 eclipse turbo did it" thinking it's a good idea.

turbo guys usually run higher octane too.

I asked if anyone had tried to lean it out for better fuel mileage, this forum is about fuel mileage, is it not? I was seeing if I could get some additional fuel mileage out of my daily driver is all.
