E34 Steering Box in E24/. Need E34 Pump?

Post by robertodonnell »

Evening chaps,

I have an E28 that I want to fit an E34 M5 steering box to. Fitment of the box is straight forward, and I know I need to re route one hydraulic line. My question is will I need to swap out the pump for an E34 one? Car is M30 based, so should be no biggy finding a pump from a 535i, just wanted to ask here if anyone has done the swap and knows if the pump needs changing out too.

Cheers,

Robert

I would search Realoem.com and compare the pumps part #'s.

Not the easiest comparison, e34 M5s have self levelling suspension so the use a tandem pump. Realoem only refers to this pump for the M5.

If someone has done this swap, I'm interested in what you did with the pump. Cheers.

Should not be necessary to swap out pumps. There is a 110 bar pump and a 120 bar pump. The e24/28 uses the same basic pump as the e32/34 without the SLS.

I knew this rang a bell from B35 / B34 swap searching!
