E91 Straight Six Bearding

Quite.

280bhp is interesting. Recently learnt the E92 had 272bhp from its N52 and there don't appear to be mechanical differences so I could understand 218 to 272. Mapping the 330i from 258 to 272 wouldn't be worth it for me. But 218 to 272 (or indeed 280) would seem a no brainer for a 125i.

It’s really interesting to find out that there was a 272bhp N52. I sold my old N53 equipped 330i because it was so unreliable but I’d definitely consider another one in future if it had an N52. Looks like they also put the 272bhp version in the X5 for a while.

No, there wasn't - the 272bhp 330i was the N53 that you found so unreliable.

In E9* 3 Series models the N52 had either 258bhp or 265bhp.

The E92 N52 was 272bhp. We did this in another thread.

Everybody seems to say the N53 is 200KW, same as the last revision of the N52. 200KW is is 268hp or 272PS.

The manual for my E46 330d gave its power output as 135KW/184hp, but 135KW is in fact 181hp or 184PS. So maybe BMW are in the habit of just converting to PS, saying that's hp, and calling it a day? Just goes to show, you can't trust the non-metric units...

Yes, and you'll be wrong again - N52 was never 272bhp.

<sigh>

Do a VIN check on an E92 330i

So what power output does this car have?
http://www.autotrader.co.uk/classified/advert/2018...

BMW Warranty site confirms it's an N52. Autotrader says it's a 272bhp. Do you think that's wrong and it's actually some other output?

[ferrisbueller]

You need the info off the sticker in the door frame but our conversation in the ///M thread would lead me to believe 272.
ETA. Starts around page 335 of the current iteration of the thread.

2979cc is wrong for an n52. I wouldn't trust AT as completely accurate tbh

I wouldnt trust AT for accuracy.

N52 258
N53 272
N52 265 (in 130i)

No idea if the above are HP or PS.

In the E92 the 330i was listed as 272hp from launch in 2006 and that was with the N52 engine... I've just checked the original BMW UK press release.

From the thread referred to above, verified using a VIN from an actual car and other VINs via databases.

[texasjohn]

Maybe it was higher in the E92. It was certainly different in the E87 compared to E90/1

Morning folks. Had fancied an E91 for a while now, it was likely going to be a 320d then discovered this thread earlier in the week. Reminded me that you really need to look for an I6 version.

So yesterday somehow talked my wife into changing our trusty honda jazz for a 330i wagon. Deposit paid. Zero options, N53, Patchy service history. Wish me luck!

Possibly been the most useful car Ive owned. Apart from my Transit Minibus but thats a different thing.....

If its on runflats dont be surprised if it feels like the steering has a mind of its own - get shot as soon as you can!

Good luck. N53 is (IMO) a very good engine BUT I'd be whipping off the top cover and looking at what index injectors are in place. Less than 11 and you might want to start budgeting for a new set at some point. If they are 11 they've been done already happy days.

Yes, a 3 litre N52 is 2,996cc.

In an E85 or E86 it is also quoted as 265bhp, but for some reason in an E89 it's 258bhp.

How about the E92?

Is that all that commonly goes wrong with the N53? And how much is a new set of index 11s?

[helix402]

Injectors are approx £170 each+a decoupling element for each one. Though as the saying goes, if it ain’t broke don’t fix it.

Contrary to some advice the world will not cease to spin if you change a change a single injector and not the whole lot together. In a money no object scenario it would be better to change six together but it’s not necessary.
