The new N53 comes in two displacements – 2.5 litres and 3.0 litres. One major difference with the N52 is that it comes with High Pressure Injection, which is basically direct injection. But the N53 does not have Valvetronic because there is not enough space in the cylinder head to implement both direct injection and Valvetronic. The mid-range engine is the N53B30U0 which can produce 218 horses at 6,100rpm, and 270Nm of torque between 2,400 to 4,200rpm which is rather low by 3.0 litre standards, but the “U0″ 3.0 litre engine is detuned (used in ’25i’ products) and meant to compete with competitor products of a lower displacement/power output. The ‘proper’ 3.0 litre engine is the N53B30O0 which does the full 272 horses at 6,700rpm and 320Nm of torque from 2,750rpm to 3,000rpm. Uite aici niste discutii de pe forum-uri germane http://www.e60-forum.de/thread.php?threadid=4887&sid= Tradus cu google : All 525i Drivers interesting, the more power bissi want;-) I by accident when browsing the net on the company DS-Motorsport encountered, and this winter promises tuning the 525i an output of 280HP So in advance ... I speak here of the N53B30 Since you can get out with a sucker on the Chipen usually only healthy 10-15hp, I was wondering how something goes. Ask me this has been for my purchase ... What was cut back, what's the difference between a 525i and 530i LCI? Engine block and head are all the same, so I decided once the work done and printed out all the parts from two units of the ETK. Compared (So were about 200 pages ...) All the part numbers and lo and behold .... Throttle, rails, high-pressure pump, DME, suction, LIMA .... all the same The only difference is the intake manifold and maybe even the DISA VE ... Here I come to the numbers on the ETK not ran .... or they were not published with intent ... Item 2 +3 is missing Is or would be so easy ... Other map another bridge and the car is better than a 530i series? Question time tonight, the price for the 60 hp.
