Re: Mod 323i to 325i
this is the same issue with the 523 and 525. i have scoured the web intensively but at most found anecdotal evidence regarding the differences. whats interesting is that:
- engine part numbers are identical
- no photos exist to show/indicate the difference (not even from the tuners)
- no torque maps issued by BMW for 523 engine (not that i know)
so there is still hope .... at least I wish

Re: Mod 323i to 325i
The engine block is identical no doubt.....
Everything else is not.... The engine block is not the whole engine since there r a lot of attachment to it..
The manifold, throttle body bore diameter etc all r different. Also, the car is running on different compression.. U need to raise the compression to get the additional oomph !! Increasing compression means strip engine......
If BMW just uses a programme to bring down 40hp, then who will buy a 325 /525 cos they know aftermarket tuner will break the code in matter of months...

Re: Mod 323i to 325i
I am no expert to car tuning. But to me, as some brudders said, there is a reason for the $40k difference. Its like a computer. would u buy the stock desktop with all the specs u want? or would u go to Sim Lim square n customise and mod one. Sometimes things u put in are incompatible. Anyway my good old sim lim square PC kaput liao in jusy 12 months.
The 325i 's extra power had been tested and tested as a product before its sold. if u mod a 323 to a 325, is it tested? Not to mention that u may in the end have some minimal savings assuming u can get that 40 bhp afterall, but does the damn modded car drives properly like the 325i...well I dont know and I will not take the risk. For all you know if it only cost u say $20k, it may well be $20k down the toilet bowl. Just 2 cts.

I support parallel importors. They should bring in the E91 and 1-series BMWs, and also the 4-wheel drive 3 and 5 series. The premium PML charges for the next higher model is rediculous, in the USA its only a few grand but here, its several tens of thousands. Thats why my stupid german colleague whole life poking fun at me, make silly grins....haigh....
