FMIC - Front Mounted Intercooler
Free Flowing Exhaust - Basically a Straight through exhaust system
Elbow - On the K14 the exhaust elbow (off the turbo) is fairly small and is a restriction. If you could unbolt it and stick a bigger turn off the turbo then that would help it breathe.
That said 147bhp was made on a Bosch 11mm, Top mount intercooler and a K14 i believe. Check out the Dyno Bible for the XUD and that gives peoples setups and power outputs.
