Pasakysiu daugiau, tai vieno koncerno brendai

Tai Jūs teigiate, jog E39 eksploatacijos kaštai yra didesni nei E38 imant modelius su analogiškais varikliais?

Bet tai ko Jūs čia gerbiami ponai užsivedėte apie tuos valytuvus? Pirkau praeitais metais, mokėjau apie 120 lietuviškų pinigų dar. Bet čia toks dalykas ar jis kainuos 120 ar 200, vistiek kasmet nekeisi, tai ten dėl max 80 litų niekas nenukentės. Važiuoklės detalės sudaro žymiai didesnę išlaidų dalį. Kas dėl paprastų tarkime amortizatorių, tai jų tiek E38, tiek E39 yra prikepta ir aftermarket, bet tarkim norint nupirkti su SEDC lieka vienintelis variantas - Krasta Auto, oficialus BMW atstovas Lietuvoje, kur tokius mortikus parduoda už nežmonišką kainą kaip tūlam lietuviui.

Vyrai, kas turit info kuo skyresi m73b54 ir m73b54TU varikliai tarpusavy?

Unlike the other engines the major changes between the B and TUB variants concern the control system rather than mechanical changes. Both variants retain the M70's twin coil-and-distributor ignition system and if there is a weak area the ignition system is it.

In September 1998, the 750i was given a technically updated engine called the M73 TU (technical update). The cause for this update was to ensure that vehicles produced after this date fell within the emissions guidelines that the government set at that time. The update was not mechanical, but the ECU's and hardware were altered to give a lower emission value.

Beginning with 1999 models, 750iL models were equipped with the M73 TU engine which, though it has the same displacement as the older engine, features the following:

*Electrically heated catalytic converters (E-cat) and E-cat control module
*Dual Batteries
*Long-life spark plugs
*Compact water-cooled alternator
*Transmission fluid/coolant heat exchanger
*Rapid-action coupling in the coolant and transmission fluid circuit
*Pulley diameters and accessory belts modified to compensate for new minium idle speed (530 RPM)


Actullay M73N would be more accurate because the TU suggests a "Technical Update" but there really wasnt any change to the motor itself, it was more of the auxilary components that were changed and not the innner workings of the engine.

Other sources indicate there was a slight increase in power and torque but dont know what those figures are. Also, I've read there were over 15000 M73's produced compared to M73N's (TU)and the source for that data was simply Wiki
