this is mos def more appropriate

You got your wish, now give me some M54 content

Please?

M54s ARE a good option for reliable power.

I agree. I would love to see some more of those turbo/sc'd whovah here. Btw the someone posted here is very very impressive.

Ok, M54 is now in with the S54. We will be keeping the E46's together and allowing the E36 guys to have their area.

IMHO S54 deserves its own sub forum just like it was already...

Absolutely but in the interest of getting E46 activity higher this is the right move.

Most of the FI S54 and M54 people know each other anyway....it kind of makes sense.

I've been so swamped with other projects, I haven't had much of a chance to even look at my own stuff. I'll get around to actually doing something worth posting about someday....

EXACTLY. No worries, we will be here when you get around to it

ok, so it has been a while. I have been diligently working on this project and have gotten a few things together... I contracted a shop to build me a motor mount, of which I don't have a pic right now, a wastegate pipe and the first two bends of the downpipe.
I'm still planning to modify the downpipe to add a flex section, but this will do for first fireup, the flex section will come before the car ever sees boost. the flex section will go over where the 3-3.5" transition takes place. the wastegate tube has a nice little flex section. The entire exhaust after the 3" pipes was cut by me and tacked together by my friend, Frankie. It was tigged by a not so local shop.

So, after much molding of the engine bay with the timeless hammer, everything fits- engine has gone in and out roughly 50 times... and this will be quiet a cluttered engine bay, but I'll try to make it clean and somewhat pretty. I'm not even going to try to put a meth tank in there, congrats to hpf in making that fit.
I have some other things to figure out where to mount, but that shouldn't be too difficult. over 95% of the fabwork is done... now I have to do things like figuring out if i want to mount the fuel pump in the oem filter location or more like the e36 obd1 filter location... but more against the framerail












I have newer pics, with the entire exhaust welded up, but they're a bit too high res... they'll be posted up after i edit them down, I'm lazy right now


EDIT ...sorry for the initial huge images, a little edit down

[Sticky]

No need to edit the images, board resizes.

Finally we get an update Was wondering where you went.

If you ask me, this is beautiful:

Just wanted our M54 friends to know prefixes have been added to this forum, so you can sort by M54 which is like having your own forum

ok, i realize I'm late

This was my first statement to Sticky, this is a miscategorization by my estimates. The M54 shares a lot with the rest of its appropriately named brothers in the m5x family (also including the US s50/s52). I think it should be categorized with those as the cranks interchange, the front timing cover is also removable. the oil pumps are used from the newer engine in the older ones as upgrades. The head hardware is largely interchangeable, timing is similar, etc, etc.
EDIT: intake and exhaust manifold also bolt-on directly even if they're not port-matched. The factory M54 exhaust manifold is port-matched to the cast-iron blocked M5x family, not to the M54. And though the M52tu is much more M54 than it is M52, due to the universe of shared parts between the two (m52 and m52tu), "technical update" isn't the biggest misnomer.
And this is trying to avoid restating all the other points Adam made above.
I think the N52 should be paired with the euro market N53 and the N55, the two other valvetronic motors.
Granted there are some differences, but the basic architecture is similar across these and the N54.... the N54 shares more with the N55 with displacement and it steel cylinder liners (which is hope, not researched regurgitated fact, I can only hope that the N55 has the same dimensions as the N54 and shares its steel cylinder liners).... If the parenthesized hope is not so, then the N55 is the perfect pairing for the N52. Despite that the N52 will sink further into the depths of being fully ignored as the N55 can still theoretically achieve SR20det status, all aluminum no steel. And if the N55 is still more like the N54, it still has valvetronic and is thus a another e9x nonM family member that belongs with its valvetronic brothers.
But in a forum called bimmerboost, with the exception of the long forgotten HPF 330i e90 one-off, does the N52 really have a place?... with the existence of the N54/N55?

Though I do understand why this grouping was originally made, and from a certain perspective it does make sense. But I think putting this engine either by itself or with the M5x family makes more sense.

Man, I really wish the N54 had an iteration without direct injection and the constant failure of high-pressure fuel pumps
Oh, it's the M54 with a TT kit... and bonus: it comes with a closed deck and more turbo (same boost, more power)

is that mean if i have M50/M52 turbo manifold, i can use that manifold on my M54

Hi Sticky, sounds good but how is that^ done?
I can sort by thread but that doesn't quite do the trick prefixwise...

Just click on the prefix. For example, to display all M54 threads simply click on M54. For S54, same thing.
