Same here.

Right now I have the Technique Tuning stage 2 kit with a slightly bigger turbo, ZHP cams, and 1.5 PSI more boost so we shall see.

In theory I think I should have at least 430whp

My goal is 500 wheel on pump gas, so the m54 might be a tougher route to go. So I suppose dropping a built s52 in my e46 wouldn't be too ridiculous, but tuning would be a different story.

How's it feel thus far? Butt-dyno wise

I know I'm bringing up an old thread, but I am wondering if anyone has every put an m54 head on m50/2 iron block. I understand the issue is a big coolant port on the m54 head that doesn't exist on the earlier model iron blocks; correct me if there are other reasons. If the one port is the issue and it's an addition to the m50 head's cooling capacity, then why couldn't we run it with the assumption that the head would simply have less cooling, equal to that of an m50 head? I honestly don't want anyone saying it won't work unless you have tried it and found that oil and water mixed, or it wouldn't cool right, or etc.. I don't have a way to properly test this on a project car or engine Dyno.

I have been curious about this for quite some time now. I honestly think it would bolt up and function, however I'm pretty sure that that missing coolant channel would turn into a massive coolant leak from the head. It would need to be blocked off, or a plate made to return the coolant moving through it to the coolant system. However, if that port leads to its own 'closed circuit' of coolant, then it might just bolt up and work. I have also read a few posts saying that the coolant in an M52 circulates the opposite direction of an M54, but I don't see that as an obstacle worth stopping over. If I had the funds to get an M54 head and an M52 short block specifically for this experiment, I would. Maybe I will this spring when I level out a bit financially.
