Outer Limits 4x4 Board

hey, friend of mine just abought a 2.5 nh with a fresh motor.
So just wanna know how to get power increase out of them, it allready has a biger exhoust, can the pump be wound open more and is it worth uping the boost a bit.
maybe a new turbo and larger intercooler also as options.

tell me what u think.

this guy cranked up the boost on his to 21 psi and runs a 13G turbo on his 4d56 and also installed a front mount inner cooler, and turned the pump up half a turn on fuel.

wow 21psi. wonder how long it lasted.

he is still driving it he wants to take it down it to 18 psi with a controller right now he has the wastegate wired shut. says it just lights the tires up on comand.

even at 18psi i still would be cautious.
