Easiest way to increase compression is to replace the pistons. You COULD mil the head but, that could cause way more issues than you should be willing to accept. Mostly because no one I am aware of has done it.

Anyone know if the N52 is an interference motor? I am looking for someone who will produce a header for us (affordably) so we can have a good option in that route. If you guys know of someone who is actually making one please let me know.

@chris, go away, if you dont think its a good idea dont comment or follow the thread. Some people want to do stuff just to be the only one who has done it.
