They all run 4.5 inch intercooler cores if you look up the specs for any of the race intercoolers that's the thickness. They also run 3.5 inch intakes to the turbos 3.0-3.5 inlets from the intercooler to throttle bodies and 3.5 inch twin down pipes. They rarely run small A/R on the turbine side and choke them. This is why there are so many of them riding around with 800 plus WHP on pump 93 they have been doing this for years.
