600hp=510rwhp (6spd), right? There's only 2 ways (without meth injection):
.
1) Destroy the engine - not immediately, but every time you boost to 510rwhp, it detonates, which takes chunks of tiny metal out of the pistons and head. What do you think happens to these tiny chunks? They ruin the cylinder bores, valve seats, and the turbo's turbine blades. Of course, it depends how often you take it up to 510rwhp, and how long you hold it there when you do, but regardless you're looking at a new/rebuilt 2jz-gte going this route (probably sooner and not later, relatively speaking).
.
2) Run a turbo so big that the lag makes the Supra practically undriveable. Huge turbos (80+mm inducer) generate very low levels of additional heat at low boost levels. They also lag like crazy... eg. with no boost whatsoever under 5500 rpm. Sure you can hit 510rwhp with a setup like this on pump gas, but who one earth would ever want to drive it? Sure, the huge turbo could be spooled with nitrous, but if you're going to that trouble, why not just put a meth injection system in, together with a more reasonably-sized turbo?
