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.

tc - turbocharger, my bad I start shortening things. Well I am strongly considering the ATS "CT27" upgrade, I'm looking for around 300hp at the crank and this seems like a good option over a used CT20b, which still is something i'm considering. ATS offers a package deal which includes thermostat and fuel pressure regulator and also a ROM tune. Where you send them ur ecu and they tweak it a little bit. If I do that, I'll have them tune the ecu for 93 octane and 550cc injectors. I figure that with a new fuel rail, water injection, (maybe a FMIC dont kno yet. The W/I will help with detonation so the FMIC may not be necessary), a downpipe (2.5 or 3 havent decided), and midpipe it should get me there. That should be good for low 13's if not 12's along with the CM S4 & LSD.
