From what I understand, the stock turbos run out of guts a tad under 200kw at the wheels. You can wind the boost up higher, but the extra exhaust backpressure and heat is all that's generating the boost, not decent airflow. I took a close look at a pair of CT12's off a 1jz yesterday, they are BLOODY TINY! To be honest I really don't see how they flow as much air as they do (just) manage to. Standard injectors (cant remember off the top of my head how big they are) are quite happy to run those stocky turbos off their dial. What pump are you using now? It never hurts to have a big arse pump, but it sure hurts to have a tiny/buggered one! Remember engines cost more than pumps.
