:Did anyone determine if the stock throttle bodies or 2 inch :inlet/outlet intercooler diameters are enough bottlenecks to negate the benefit of 2.5" intercooler piping ? ( stock turbos ) Can the 2.5" pipes be installed with the engine still in the :car ? Any problems with the 2.5" not being bolted in...just supported by couplers ?
Without the larger throttle bodies coupled with the 2.5" intercooler piping and the larger intercoolers you cause bottlenecks in each of those locations. The 2.5" piping that I've installed has not been supported just the connections with couplers and having to find the hoses for the recir valves
