And on the point of your 300-400 cam.. Yes the cam alone may only cost 300-400, but once you get everything else to go with it to actually install it (all the gaskets, better springs/retainers/locks, maybe a bigger better timing chain depending on how crazy the cam is...) you are looking at 1k+ just for a cam install. And it is an extremely involved job.. If you have never had your hands deep in a motor before I'd stick with finding a used turbo kit for around 1500 and find a local tuner. Or do A LOT more research and report back.
