325d is detuned (engine management and possibly smaller size turbo) 330d and 335d is twin turbo.

335D has twin turbos....and more torque than the ZF 6HP26 manual box can handle.
I think the 325D & 330D are probably closer related...

Instead of each turbocharger feeding three cylinders, the 335d uses two different-sized units working in sequence. At low engine speeds, the smaller turbocharger is effective immediately, producing 95 per cent of the available torque at just 1,500rpm. By 1,750rpm maximum torque of 580Nm is delivered and, as the engine speed heads towards 4,400rpm, maximum horsepower of 286hp is achieved as a result of the induction air now being compressed by the larger turbocharger.

This wave of torque from such low engine revs enables the 335d Coupé to power from zero to 62mph in 6.1 seconds while the Saloon and Touring versions take 6.2 and 6.3 seconds respectively. All three models, fitted as standard with a six-speed automatic gearbox with steering wheel-mounted paddles for an alternative method of gear change, are electronically limited to a top speed of 155mph, yet are still capable of achieving economical fuel consumption.

The 3.0-litre engined 325d Saloon 0 to 62mph in 7.4 seconds (manual) Vmax 146mph.

The 3.0-litre engined 330d Saloon 0 to 62mph in 6.7 seconds (manual) Vmax 154mph.

The 3.0-litre engined 335d Saloon 0 to 62mph in 6.3 seconds (Auto) Vmax 155mph.

330d is not a twin turbo, but has a larger one than the 325d.

I don't think there is an easy or cheap way to upgrade a 325d to 335d.

I doubt a twin turbo conversion would be worth it..the brakes, suspension, etc would need upgrading...plus the box needs to be a beefy auto before you start.

However DMS do some stonking remapping e.g 330D gets close to the 335D figures. No doubt when they get there hands on the 335D all manner of tarmac rippling torque will be available.

From www.DMSAUTOMOTIVE.com
BMW changed a lot of peoples perspectives on diesel engines when they bought out the 330D in 2000. Although the output was very impressive, it was limited to fit in line with European company car tax laws, this allowed us to re-map the engine management transforming the performance with torque levels approaching that of the M5. With other great models such as the new 730D (up to 260 Bhp), X5 3.0D 2004 model, 320 CD (up to 190 Bhp) our upgrades have become very popular. The BMW lead on performance diesels moves further on with the release of the 535D twin turbo, our demo has stunned the press out-performing any production diesel car with 0-60 5.5 and 0-100 13.4
This link to a review of the o46 204 BHP taken to 260BHP http://www.evo.co.uk/carreviews/evoc...bmw_330cd.html


I understand from a mate that has a 535D that the twin turbo route also offers enhanced throttle response over his previous car 530D......I will report back in about 7 weeks time.

...but you can make CHIP-TUNING with all varieties, so torque and HP
will be enough!

All have different engine management which utlizes the different turbo configurations.

All have some form of forced induction.

320d one turbo.

330d is a newer engine block and has one variable vane turbo.

335d utilizes an engine block which has been in use since 1998-99 and has a sequential turbo setup (1 small behind 1 big).
