Should I create a dedicated step-by-step M54-engine conversion thread?

Hydro-z4
Would much appreciate your M54 conversion thread. I have a very basic question for the conversion with this engine - I have a 2004 E85 with the 2.5i M54 engine and I have just taken a good look underneath, I cannot see any obvious mounting points for the pump, I assume it will be somewhere below the alternator but cannot see any mounting points that would be used for the pump, have you a photo of a pump fitted in the area - is the mounting integrated with the alternator mount ??

I suspect you sourced the pump without the M54 mounting brackets?
They are pictured below...

If you're missing these brackets then they are available separately from BMW.
They're also used for mounting M52/M54 engine in E36/E38/E39

hydro-Z4 - thanks for your quick reply. I have sourced a serviced LF-20 pump which has two mounting brackets attached, one is an aluminium casting attached by 3 bolts to the face of the pump, the other is a steel bracket that attaches somewhere on the engine to the rear. The problem I have looking at my M54 current engine pulley configuration is that I cannot see how the whole pump assembly attaches to the engine. I have a frontal picture of the M54 engine (loaded from online) with a hydraulic pump installed, it appears to be positioned directly below the alternator with an idler pulley in between, I am now assuming that there are no mounting points for the pump directly on the engine casing but a mounting frame that holds the alternator, the hydraulic pump and the idler. Am I on the right track and if so I will obviously need this mounting frame to attach my LF-20 pump and the alternator and idler. I will try an add a picture file in another thread to show the pulley arrangement as I have discovered to see if you agree with the serpentine belt route.

I attach a picture of the current serpentine belt routing on my M54 engine and a picture of an M54 engine with hydraulic pump installed from pictures I obtained online, it looks as though the pump mounting is integrated with the alternator mounting

Thanks for the mounting bracket pictures, I will take advice from others and drop the LF-20 and go for the LF-30, can you tell me where the brackets attach to on car with the M54 engine

The steering pump brackets mount onto the M54 oil filter housing

This picture is pretty clear on location of mounting screws.

Thanks Z4_hydro - saw your msg. and have just gone outside and stuck my head under the car and can see the two mounting points on the bottom of the oil filter housing, had me confused at first since the lower idler pulley is mounted there which clearly has to be removed to accommodate the pump mounting brackets. Assume it will take either the LF-20 or LF-30 brackets.

Raymond Harper ,
Hi Raymond, my power steering went out a few weeks ago and I'm considering a rebuild.
Can you send me a PM with these conversion photos, it would help a lot.
Thank you
