I looked at FAQ and preformed seach. I was unable to find anything. https://www.nopistons.com/forums/pub...1047683358.gif



I would like to know what advantages are for these type of ports and the disadvantage. I have to option to daily drive my car or not to daily drive the car. The set up that I will be going with for turbos is BNR satge 3. Not sure if I will go seq. or not.



What kind of number would you see with this engine and the proper mods to the fuel system, exhuast with hig flow cat or mid pipe, PFC, and v-mount intercooler.

with the stock turbos and a cat, you'd be better off with stock, or a mild street port. the larger ports, like the bridges, have to be able to breathe to make more power, and the twins arent going to let them.
