Im still after minimal lag with decent 330bhp from a std compression 2wd YB, it will run 803s and a 3bar MAP, what can be changed on it to improve throttle response on a std engine?
exh manifold- change to a tubular type?
inlet manifold- change to a Swedish type?
T34 exh housing-down size to a .48 from .63?
Pace rS500 type cooler or 2x 2wd Icooler welded infront will be sufficient for cooling and response?

anything recommended or should I steer clear of? Apparently at my power level and even 380-400bhp a swedish inlet will reduce throttle response? I could polish the trumpets and inlet inside to speed air flow maybe??
