ok, first thing is which 2l do you have? 2l-1 or 2l-2. 2l-1 is the "slant" engine with roller rocker cam. 2l-2 has flat tappet cam.
what turbo are you using?
pre turbo egt run about a max of 700c (1300f).
not sure if 2l-1 run oil squirter's or not. 2l-2 generally does.
don't worry about high boost. provided your not running the turbo inefficient high boost won't kill the engine. to much fuel is the big killer.
if running original turbo setup just use stock boost which can up to about 10lb.
1kz bottom end is different ball game to L series engines. 1kz is substantially better. L series do have a habit of snapping cranks.
