Hi, I am based in Brisbane and am looking for recommendations of a reputable workshop who specialises in evos. My engine was built by MRT with the previous owner and is a 2.4l with ECUtek tune. For some reason they kept the standard turbo and I want to upgrade this due to lack of mid-high range power. I love the instant torque and pull of the current setup but after about 130km/hr is just doesn’t pull anymore.
reccomendations on turbo (bolt on standard frame preferred) and workshop will be highly appreciated.

thanks
