The kit i was looking at comes with a t4 turbo. Too large for me, i want it to be streetable, and with this in mind i was aiming towards the gt35r. for now i got a t3/4 and was going to use that until i get the 35. I am aiming to hit 500hp on a fully built motor, and wondering wich i would be better off using. Does the top mount sacrifice any low/mid end to achieve all the high?
