Why such a small (7cm2) exhaust housing?
I wasn't impressed with the T3/T4's I saw or used. You had to overboost them just to push any real airflow.
I went to a TD05/6H-20G and even at 15psi it made the T3/4 hybrids look like the stock turbo.
Though I was running over 2.6L (Conquest TSi) instead of your 2L. I ran a 16G on my GST with great results.
