if the ports in the head are D shaped you may see a power increase, but if they are oval shaped like the m52tu manifold you will lose power from a turbulence during the step-down at the ports. you will lose low end either way due to slower air speed at low RPM, but not by very much, and top end may see a little bit of increase if the ports are D shaped. i think a more frugal, visible upgrade will be to port match the cylinder head and stock manifold. either way good luck with this. =]

i read the whole thread, i just wanted to add in my $.02
Hi,
for an adaptor to fit the M54B30 Intake Manifold to the M52B28Tu throttle body you can look here:
www.too-much-concepts.de
You can also use these adaptor to fit a M54B30 engine in a M52Tu car.
Regards Joerg
I have an adapter from Turner...But thanks for the option

Hi,
the M54B30 and the M54B25 Intake manifold are different. And the M50 is a much earlier engine generation.
did you use this adaptor:
Turner Motorsports - M50 Throttle Body to M54 E46 325 Intake Manifold - Adapter Plate
Read all 82 posts...there is much more to it than you think.

Joerg is one of the first to do this swap, I've seen his post on the German BMW forums. Just so you know, you will have to modify that adapter to fit the manifold and TB, Joerg's should be a direct bolt on.
I'm going from a M52tuB28 intake manifold to a M54b30 Manifold...I've got covered. Project is on hold for a while until I can get caught up with school.

No shit sherlock, why don't you re-read what was posted before you come off as an idiot. The adapter wasn't meant for M52tu/M54 conversion, but for the M50 throttle body. It will not work on the M54B30 without modification to both the throttle body and the adapter itself.
Always so harsh...
I know what I have to do. I'm already in possession of the adapter plate...the Throttle body needs to be ground back to fit the ICV.
Joerg said M54b25 and m54b30 manifold are diff't...I'm using a M54b30...
@Joerg- Looks like a nice part
Do you seal the flat side to the manifold and the TB seats on the O-ring? How does it clear the ICV?

Hi,
the M54B25 throttle body has the same pattern as the M54b30 but the plate has a smaller diameter. I do not know anything about the M50 and the throttle body of this engine.
My adaptor is a direct fit for the M52B28Tu throttle body to the M54B30 intake manifold. It is also perfekt for an engine swap.
You can download the installation Manual with more pictures from my Homepage.
www.too-much-concepts.de
The O-Ring will seal the adapter to the manifold and the original seal of the throttle body seals to the adaptor.
I have 252° Schrick Cams, sport exhaust, KN Filter, UR Pulleys and the M54B30 Manifold and my Z3 makes 228hp with the oem chip.

My Z3 had 108tkm about 67k miles on the odometer. Same time with the cams a Beisan Vanos kit were installed. The cams were OEM regrind to the Schrick 252° profil, this is much cheaper.
We had a BMW 328 in our firm with about 500tkm (316k miles) without any big trouble.
I thing our mild tuning will not harm the engine.

C'mon fella's. Why take a great (and possibly epic) thread, and ruin it.....no need for name calling. SB will just close the thread, and that won't help anyone.....now...behave...lol.
@Iceman....for the sake of good....please stop antagonizing Horney.
@Horney....got any updates?

Need to have my pulleys and tensioners, driveshaft guibo and center mount replaced
Gonna need another two weeks to gather the cash to order. I can do the pulleys myself but I'll need a lift for the underbits :/ Prob gonna get it done over Thanksgiving break.
That's about it. I need to start making payments to my Momma tho...she's kinda pissed that it's not 100% yet...but what used car is? lol

Ughhhhhhh...so...I've got a deal on a M54b25 manifold. What can you tell me about it compared to the M54b30 in regards to size and runner length? I'm almost 99.5% sure they're the same, but I need to know for sure.
And please, no BS responses from the peanut gallery.
Thanks.

Sorry, I need this to happen. I <3 real life drama like this.
Horny, when you get this done, me, my car (assuming she's fixed) and as much Sam Adams that can fit in my trunk, are heading your way.
Now they dropping and yelling, it's a tad too late, Nate K and Rayzah Blade had to regulate.

Hi,
go for the M54B30 manifold!
The M54B30 manifold will give you 6,5HP on an BMW325 e46 (M54B25).
M54B30 and M54B25 manifold are different!

Damn
Guy is selling two M54B25 manifolds for dirt cheap!
Joerg, I've been thinking about your adapter plate and would like to give it a shot. I'm having a hard time navigating your site though. Do you have an email I can reach you at for further communication?
