that wont get much boost because the exhuast gasses push the turbine round and with a big pipe there wont be as much pressure

I don't think he'll have problems getting much boost, just maybe a good amount of turbo lag. I'd be more worried about the size of those intakes on the head!!!!! At least an oval port with the turbo, c'mon!

i have been told that round port is better when ported properly because of flow angles

ive been told that to.
