Fitted Bosch :) can you get more than 20psi on a K14??

[mark_airey]

Iirc the k14 is the smaller of the kkk turbos so it may run out of puff higher up the rev band but you should be able to put the mbc on it, just cut the metal pipe as you said.
Not sure on peek boost on those mind

Wrong way round, K14 is the bigger one, they are pretty much the same as a T2 and shares the same manifold, its the K03 thats smaller. ruan ran his at about 29psi for ages so yes to answer the OP's question
