c14nz

So I have a C14NZ and I want more power and something interesting. Had a few ideas but I’ve not really settled on much and then I saw this. Which appears to be c14ne bottom end with a c16se head (multi point) but with a single point inlet and a little turbo bolted on. I think I can achieve this...

so recently my engine (C14NZ) made a weird noise, it's not any form of engine knock, it kinda sounds like it's scrapping or boiling. the engine has oil. it sounds like its coming from the cam cover. The engine still runs like it always has ran. any ideas?

I'm not exactly well knowledge with car mods, but a friend of mine mentioned getting a carburettor... as a joke ofc and I thought about Individual throttle bodies, now would getting an ITB's for a c14nz be beneficial in terms of horsepower gain, or am I complete dumb idiot for thinking such...
