After an engine swap, the original servo pump no longer fits. If you want to continue to have steering assistance, you have to install a different servo pump. We offer Chase Bays power steering kits and high pressure hoses for the most common BMW 3 Series E30, E36 and E46 engine swaps. Regardless of whether another engine from BMW, an LS1, LS2, LS3, LS6, LS7, 1JZ-GTE or 2JZ GTE is installed, you will find it with us. We also offer a universal servo oil cooler, which optimally ensures that the servo fluid does not heat up too much and always works optimally.
