M52 vs M54

[sclass]

Wsup,

I drove my mechanics E46 320i (steptronic) a few days ago, I'd left my car with him to work on. It struck me how effortlessly rev-happy the motor is, my 328 feels dead 'reviness'-wise. Also the motor's smoothness is quite noteworthy even at the redline.

My car is like Lennox Lewis and the M54 is like Floyd Mayweather! :=):

The M54 and its stuff is lighter, so that might account for part of it. Other than than the steptronic might have higher ratio diff so that would also the car eat through the revs a bit faster.

its the restrictive intake manifold on the 328i...

 

[Raybimmer]

Anybody know the times from idle to limiter when revved in neutral ? Years ago Toyota Corolla adverts for twin cam motors claimed less than one second if memory is correct .

 

[sclass]

If it's mainly down to the restrictive intake then will an M50 mod completely change it's character?

 

[moranor@axis]

read your other thread if you do that it will be a completely different car

 

[sclass]

Ok Moranor...if you say it 3 more times I'll do the mod...I think :rollsmile:!

I know you're right, I'm just loving the low down kick :=):

the M54 also has double vanos which the m52 does not

 

[Sankekur]

Is this case true but not always, as the M52's that came in the e46 had double vanos.

The M54 engine in our E46 320i is a real gem! Very lively and sounds great! :=):
