Well I'm not sure about the 2L, but my 1KZ-te comes from the factory with 12 PSI. I have read that 1100*F or 600*C was about as high as you want it to get. I don't yet have an EGT gauge on mine yet, so I couldn't tell you what it is actually running at. The lower end on the 2L and the 1KZ are pretty much the same aside from the bore, although I don't know if the 2L has oil squirters to cool the underside of the Pistons?
