325i

[RexKing86]

Well this is strictly a question ive wondered... Is there really a difference between the 325 in the E36, and the one currently in the E46? I know that the older ones have OBDI and NEW OBDII, but is that the only difference, because they have diferent HP & Torque ratings? Im also assuming that the new one does have a 2.5 I6 correct?

E46
Base Engine Type: Inline 6 Horsepower: 184 hp
Max Horsepower: 6000 rpm Torque: 175 ft-lbs.
Max Torque: 3500 rpm

E36
Base Engine Size: 2.5 liters Base Engine Type: Inline 6
Horsepower: 189 hp Max Horsepower: 5900 rpm
Torque: 181 ft-lbs. Max Torque: 4200 rpm

Im really just wondering, but I know some of you out there know!

They are different engines. They are tuned differently also. Remember, the m50b25 was the top of the line (non-M) I6 for the e36. The m54b25 is the entry-level engine for the e46. That is why when people come and ask if they will feel a loss of power going from an e36 325/328 to a e46 325/323, I always suggest they hold on until they can upgrade to a 330 instead.

Ya that makes sense, it has 5 less HP, but i thik that it being 'entry-level' makes them not want to tune it as well. I cant wait to get a 330Ci in a few years when i have more cash. BTW you have a 328 as do i... how much faster/peepier is the extra .2L? (if you know of coarse)

Not much faster. Then 2.8 is rated at 193 hp. However, the maximum torque is 206 lb-ft. A stock 328 will not be faster than a stock 325, but may feel a little peppier at times. 325 has the modability that comes from being OBDI.

Just a few points; the M54 B25 isn’t the entry level I6 The M54 is produced in three formats B22, B25 and B30 the E36 325 is a M50 this was produced in four formats B20 +/- vanos B25 +/- vanos The E36 328 is a M52 produced in three formats B20 B25 B28.
But not all these formats were used in the 3 series

Allow me to be more specific: my post above refers to US spec models only.

I beg to differ. The 328 is a full second faster off the line than an E36 325. I've driven both cars and the 328 feels much faster and is a tad more quick.
