anything different between '06 and '07 323i other than software?

epiphone3 · 09-20-2006, 03:59 PM

Hey guys,

I was just trying to find out if there is anything different, other than software, between the 2006 323i and the 2007 323i as the 2007 model is packing 200 hp vs. the 174 hp in my 2006.

Any one know for sure? I know the 328i has different pistons, etc. than the 325i but I was curious if it is a different situation with the 323i and I might be able to get a reflash my 2006 323 to 2007 323i software for more power?

The canadian 323 is a 2.5L the 325 and 328 in america are 3.0L

I think I confused you. I am actually trying to compare the 2006 323i (174 hp) to the 2007 323i (200hp).

The information regarding the 328i and 325i was for comparison between those two cars and how they are different in more than just software.

probably the year? software wise they are both the same!

Ummm... the 2006 has 174hp. The 2007 has 200hp. There HAS to be a difference other than the year.

I am just wondering where you got the info for the 2007 323i available in Canada. www.bmw.ca still lists the 2006 models. They don't even have the 328i/335i Sedan yet.

The 2007 E90 owners manual was posted here on E90 post a little earlier (like a week ago?) and it showed the 2007 323i with 200hp and I believe 180 ft-lbs of torque.

the 325i is 3.0 in the USA only. Here in mexico the 325i is 2.5

And here we do not have 328.
we have e92 325.

Do you know what the E92 325i has for horsepower?

The same as the '07 323 in canada. Im almost pretty sure the 323 name plate is used only in USA & Canada.

I highly doubt that... the euro spec 325i from last year had a 2.5 liter 218hp.

If they are using it in the place of the NA 328i, I guarantee it at least has this amount of power

canucklion · 09-21-2006, 09:51 AM

the 323's are sold elsewhere, and it wasn't even sold in the US for 2006

damn. I wish E90Fleet would answer this one!

Probably the same as the sedan - 218hp.

Which begs the question, why worry about tuning your 2006 323i to 2007 323i specs when you could tune it to 325i specs?

Both the 323i and 325i are 2.5L N52, and unlike the two different versions of the 3.0L N52, they probably have the same exact intake.

I thought of that... but are you sure they have the same intake? I thought that the 323i was 2.5l detuned from the euro 325i 2.5l in the same way that the US 325i was 3.0l detuned from the 330i 3.0liter.

It would be pretty tight to have the 2.5 liter six putting out 218 bhp! I am jealous of the euro 325i owners... If I had a choice between the 325i in Europe or in NA, I would love the euro one.

canucklion · 09-21-2006, 01:54 PM

I'm willing to wager that the cost of you converting your 323 to 325 specs would be more than the price difference between a 323 and a 325.

you may be correct... what I want to know though is if I can get to the 2007 323i spec just by a software re-flash or if there is more to it.

That could be. Actually now that you mention it - that would make sense. So if that is the case, then it would beg the question of whether the 200hp 323i is also using the intake from the 325i in order to make 80hp/Liter.

mhaw2001 · 09-21-2006, 08:53 PM

Could it be just a new SAE rating that gave the 323i a higher HP rating than the 2006 model which mighty have used the older standard? Lots of Japanese cars took a hit in exagerrated HP ratings (Nissans, Infiniti, Toyota Honda) and some actually gained HP under the new standards (Corvette C6, Pontiac G6). Is it possible that the 323i was underrated all this time and nothing is different between the two years?

Maybe... however, I don't think so because the peak torque also went up to 180 ft-lbs at 4000 rpm (from 174 ft-lbs @ 3500 rpm).

Because of this change in the torque curve, I would think that it is at the very least a software update

tctic · 09-22-2006, 08:46 PM

Could this be the answer to this question? A new engine designed for 323i from the start? Look at N51. (Image courtesy of E90Fleet) The hp bump for the 323i may seem plausible as the 325i is now replaced. This newer engine will close the gap between the previous 323i detuned 2.5L N52 engine with the new 328i engine.

this is very possible... if true, probably bad news for me as it would probably mean that more than a simple reflash would be required to bump up to 200 ponies
