The N54 Port Injection Conversion Kit (PICK for short) is a combination of products and software that have been carefully developed by Nexsys Motorsport. While the N54 platform is relatively easy to make good power on, it struggles with reliability and expensive repair costs normally associated with the high pressure fuel delivery system. The piezo direct injectors that the N54 engine utilizes are unfortunately very unreliable (BMW has gone through 12 different revisions) and extremely expensive. At the time of this writing a new set of index 12 injectors costs $2759. The second weakness in the fuel delivery system is the High Pressure Fuel Pump (HPFP) which is a swash plate piston design that commonly fails and is limited in flow rate for high power applications (especially when ethanol is involved). At the time of this writing a new BMW HPFP is $1051.
