With those tiny arse turbo's it might. Our engines flow lots of air. Your drive pressure will go off the chart and may require those 44mm Tial wastegates. You will get better all around performance with the G30's, they have a larger exhaust housing and won't back up the exhaust so bad. I have a set of twins also. Mine are Zonarotor turbos the size of GT3076's. At 11:1 compression you won't have any lag. The problem with the smaller turbo's is you will have little control over how the boost comes on. The bigger ones will give you some adjustability.
