Hey people I'm finally gona pick my little 316 coupe tomaz! WOOHOO! Got a quick question which has been brewing in my head. Would a 318 inlet manafold if fitted to a 316 give any increase in power, not much needed to be honest, just that little bit more. Is it possible? And if there is some sort of gain made from it, which manafold would fit the 96 (N reg) M43B16? Would it be the M42B18 or M44B19 maifold? And would the ECU require a re-map to suit the higher air intake?
Greatly would appreciate any advice.
