Dangers of Running Rich, 3sgte owners Options

[jgreening]

Well, ten days into ownership of the 3sgte and I can safely confirm what everyone else has said over and over....these engines run very rich. I have read many posts about this and about the fact that Toyota made it this way to avoid lean conditions. However, I would imagine that running an overly rich condition cannot be good for the engine over time either. I am wondering whether for engine longevity and reliability purposes, us 3sgte owners should take action either through an S-AFC or stand alone to lean out the A/F ratio. Obviously, we can see some horsepower gains from doing so but I am particularly interested in responses dealing with engine life.

I figure because they are a different generation. The 5th Gen Celica and MKII's MAY have a different pump setup, its worth looking into. I did some reseach and found the Supra pump would fit with not much fuss so I just got that one, gives me room to breath when I put in the 550cc's and upgraded TC.
