moggle Posted December 13, 2007 Report Share Posted December 13, 2007 I am in the process of buying a 325d tourer (2007 model) which is the detuned 3 litre model. The 325d is rated at approx 190bhp. Are there any fundamental mechanical differences between the 325d and 330d? Alternatively is the difference in outputs down to the mapping of the CPU?

gizze Posted December 13, 2007 Report Share Posted December 13, 2007 Think it is just down to the re-map. Link to comment Share on other sites More sharing options...
Ben Posted December 13, 2007 Report Share Posted December 13, 2007 You sure the engine isn't one of the old ones, rather than just de-tuned? I have no idea, but thought it was a possibility. Link to comment Share on other sites More sharing options...
CarMad Posted December 13, 2007 Report Share Posted December 13, 2007 I think the 325d in the 3 is a detuned 3.0d, the other engine only went into the 5 series. I think the newer engine in the 325d is quite good. Link to comment Share on other sites More sharing options...

This is confirmed if I put the registration into the free demo HPI check on Autotrader web site. It is an ex-BMW owned car released to the trade. It was registed mid July and has covered around 1100 miles since then. I am hoping to test drive on Saturday. I am sure I will not be dissapointed with the performance after owning a 130bhp Audi A6.

Tizzy Posted December 14, 2007 Report Share Posted December 14, 2007 It's the same engine, there may be a slight change to the turbo, or else it is just the mapping. I drove both when deciding which 3 to buy and from memory performance wise when actually driving there's very little difference between them, but fuel economy is a little better on the 325d, so that's what I'd go for. That said I went for the 320d, which whilst it lacks the nice 6 cylinder whine is actually not that much slower than the 325d and the fuel economy (my main driver as I do massive mileage) is dramatically better, with over 50 being achievable on the motorway Link to comment Share on other sites More sharing options...
gizze Posted December 14, 2007 Report Share Posted December 14, 2007 I think I am going to get Fiona a 320d sport touring, with a remap you can get 210bhp and 450nm, and it will still return 40+ mpg all day long, in manual form. How are you finding yours Tizzy? Link to comment Share on other sites More sharing options...
Cleybrooke Posted December 15, 2007 Report Share Posted December 15, 2007 That six engine is very smooth - However I've just purchased a new 320d touring with the 177 Bhp and perfomance wise it is very impressive - 60 mpg and lower Co2 swung it for me - that and the massive discount I got the car....

gizze Posted December 15, 2007 Report Share Posted December 15, 2007 I have been offered a 177bhp for £26.5k out of stock, or a 6 month old 163bhp for £22.5k, not sure the extra each month on the 177bhp version is worth it, I will remap it anyway so both will produce around 210bhp, so it comes down to economy really, speaking to people it seems about 44mpg is the norm for the 163bhp and 48mpg for the 177bhp. If it were 40mpg vs 60mpg it would be an easier decision. Link to comment Share on other sites More sharing options...

I have had a 320 before so decided to go for the 325d tourer auto, leather, bluetooth, upgraded 17" alloys, 1000 miles for £500 more than the 320d.

BuggyBen Posted December 23, 2007 Report Share Posted December 23, 2007 What about the Alpina D3? Drove one the other day and it really goes for a 2.0 and it looks good in the touring version. Link to comment Share on other sites More sharing options...
gizze Posted December 23, 2007 Report Share Posted December 23, 2007 I would go for the Alpina too, now the deals on new 320d M-Sports is gone the D3 is even more tempting. They have stopped production though so has to be one from stock, rumour has it that the D3s will be based on the 323d. Link to comment Share on other sites More sharing options...
moggle Posted December 24, 2007 Author Report Share Posted December 24, 2007 I have bought the 325d tourer and it is a massive improvement over my old 2002 320d tourer. The extra power and torque is very noticeable giving the car excellent acceleration. Being a 3.0 litre 6 cylinder the engine is very quiet, even when accelerating very hard. At an indiacted 100mph the revs are around 2500rpm. The car does inspire confidence to drive quickly! I expect the performance to improve with a few thousand miles covered. At the moment it has covered 1200 miles. The OBC indicates around 37mpg on journweys where the power is being used. A slow trip across the M62 on Saterday saw 47mpg on the OBC for a 60 mile journey. Not sure how accurate the OBC is yet. Even so the fuel consumption is not bad for a 6 cylinder engine with automatic transmission. With regard to the D3 Alpina, they do look good with the body kit, however the auto was a priority for me. Also I chose the SE model rather than the M sport for a more comfortable ride.

moggle Posted December 24, 2007 Author Report Share Posted December 24, 2007 [ QUOTE ] That is excellent consumption figures Mike, is your car a post sept 2007 model? [/ QUOTE ] The car was registered in July 2007. I suspect it was the last of the production run before the factory closes for holiday and they retool for any facelifts, which then came out in September. There are a number of pre resigistered cars at BMW and non franshised dealers at present. They appear to start with a "Y". The car I bought had 1000 miles on the clock, so it had a little use. I managed to get it for £8k less than list, counting the fitted extras, so it was a reasobable purchase. I have just filled up for the first time so I will check the OBC accuracy for MPG. My last 320d was optimistic by 4 to 5mpg. Is this still common for BMW cars to read optimistically? Link to comment Share on other sites More sharing options...
gizze Posted December 24, 2007 Report Share Posted December 24, 2007 I found my 535d and the 335i was around 1mpg out at most, our 120d seems to be bang on. Link to comment Share on other sites More sharing options...

[/ QUOTE ] I have just filled the car for the second time and calculated that the car returned 36mpg. The OBC was showing 37.6mpg for the same calculation. The test was not filling brim to brim so there would be a small margin or error. It does show that the OBC ir reasonably accurate, unlike my old 2002 model BMW which was always around 4 to 5mpg out. The majority of the miles were on empty motorway runs over Chritmas at 90 plus mph. Link to comment Share on other sites More sharing options...
gizze Posted December 27, 2007 Report Share Posted December 27, 2007 Just been reading up on the 325d and tuning potenial, basically the tuners who know what they are doing are getting 270bhp from these, exactly the same as you get from the 330d. ESS in Norway are getting this for around €800 and Hartge are also getting the same, Birds offer the upgrade for £1100, but with a full warranty. Seems like the one to go for if you want to remap it, you can get Nav and stereo upgrade and the remap done for the same price as a 330d with exactly the same performance.

moggle Posted December 27, 2007 Author Report Share Posted December 27, 2007 gIzzE, thanks for the information on tuning. I will have a look at the web sites. I have heard of Hartge and Birds but ESS are new to me. Do they only work in Norway or do they have UK branches? Mike Link to comment Share on other sites More sharing options...
gizze Posted December 27, 2007 Report Share Posted December 27, 2007 No, not in the UK, they are big in the States. Although you could ask Roy at C A Automotive as he does a lot of business with the ESS supercharger, so they may be abke to supply him with the code and he could possibly do it at his place. You have to be a careful with the Hartge remap, there are two, the first one takes it to the same output as a 330d and the second takes it to the same as a chipped 330d.

I note the peak torque on the standard car is around 2000 rpm and BMW claim it is at 1300rpm. I have noticed manufacturers tend to incorrectly state where peak torque occurs in the rev range.
