Also, has anyone done a muffler delete for the m56? comparisons to a regular 325i?

The only thing they have in common is the diameter...so if you were getting a CAI, you'd get a 330 one. As far as OEM parts, they don't share anything. Intake boots, MAF, air box, air filter are all different. We actually have the same air filter as an M52 328i.

The SULEVs have the same muffler as the 330 too, right?

Yup. Only the rear section is the same.

Did the golf tee mod today, it's a lot lower and and the change is most noticeable at 2-3.5k. I like it.

Here's my bumper looks like I was wrong not like the zhp. But still nothing I've been able to find on other 325i's. anyone know if we can put a mtech ii diffuser on this bumper?

Lol that's just a standard bumper. No diffusers will fit it unless you want to shell out the money for an ACS rear skirt.


Lets try and keep this thread on track please

Sorry, isn't this also a general m56 question thread?

+1 I thought this was general m56 discussion.

This thread is in the engine forum - "general" meaning anything M56 engine and driveline related. The M56 has the same bodywork as every other facelifted 325.

Even if it isn't I propose we make it the general m56 thread lol

Lol forum moderators like to keep the forums fairly on topic is all. I've tried having this thread moved to the General Forum before to no avail.

Btw the only reason your bumper looks different is the angle. All facelifted e46s without Mtech I or Mtech II have that, it's just not really visible.

Yeah I didn't know lol. Another random off forum question which I can't seem to get an answer too on other threads. will my stock fog lights work with the mtech zhp front bumper? If not can I get special brackets or something?

No worries.

No. I have an Mtech II (aka ZHP) front bumper and the fog lights are completely different in their size and the way they mount. The only way is to get a new set of fog lights that'll fit.

Another member and I tore my car apart over the last two days to change the oil pan gasket btw. I have some pictures of the bottom end, oil pan, etc. that I'll post up later. My oil pan was clean and completely sludge free

Very nice to know. On a side note when I first got the car I seafoamed it and 0 smoke came out the exhaust or unnoticeable. When I ran it in my Acura it filled up the whole neighborhood haha.

I've heard mixed results and mixed opinions on whether it is or is not worth to seafoam it. I figure drive it hard every once in a while to burn off all the carbon deposits and it'll be fine.

When I changed my intake boots last week, my throttle body was completely spotless. My ICV had some deposits built up but nothing too bad.

I just seafaom it as preventive maintenance, but it seems like this car doesn't need it at all. I took apart my intake as soon as I got it. Spotless throttle, very little on idle control.

What I noticed though was some deposit in the disa valve hole, very little though. I read its normal I still dont know why there is oil there. Does oil pass by there or gas?

DISA controls the intake so no, it doesn't have oil or gas flowing through it. Did you remove your DISA?

Yes I removed the disa. Any idea why there would be deposits or maybe just dirty air. Here is a picture. Like I said I read its normal and I saw pictures of others with the same amount of grime just want to know why.

Here is my disa valve. Maybe it's the air and any dirt that gets left behind maybe from the condensation from the heat is ending up like like deposits or grime.
