Sorry, late to the thread but am I understanding correctly that the e34 535i power steering pump is plug and play interchangable with the s38b36 power steering pump? I ask because I am putting the b36 into my e30 m3 and need to delete the sls feature. Any know if the s14 power steering pump will work on it? Thanks

My method is to make a simple modification to the original pump! Doing it this way means you can remove every part of the sls system with no worries of leaks, over pressuring etc etc.... You can also get rid of the monster pas/sls reservoir and use a standrd ATF one instead. (must still use pentosin). This will also resolve the problem for the E30 M3 transplant

Here's step by step pics.....

1. Remove the two cross head bungs. My method is to use an Impact driver, one good wack should do it!

2. Remove the springs and pistons. Usually these just fall out, If not use a magnet. Put the 2 Cross head caps back in (use new sealing O rings if you can).

3. Use a suitable bolt or union with a copper or ally washer to permenantly cap of the SLS .

And there you go! Takes just a few mins.. SLS gone....

this only works on roughly 70% of the pumps. 3.8 always have the system above, some 3.6 don't.

On mine, I had to machine the camshaft.

there's no telling which you have, apart from the latter having a different thread.

Ofcourse you can always get one of the 2/3 majority pumps and carry out above method.

If a normal e34 535i pump plug and play fits and deletes the sls as the same time, that seems like the best way to go to me. I just don't know if it fits!

I don't think the 535 pump fits

if you make a search here in the forum, you will see it doesnt fit....

Is there a pump that fits and doesn't require such modifications?

No.

The 535i pump doesn't fit.

Believe me, I tried. Its 2-3cm bigger b.c of the extra sandwich plate which houses the SLS aperture.

Besides that, the PAS S38 pump brackets don't fit the M30 pump and the M30 brackets don't fit the S38

I really feel like you did not have a 535i ps pump when trying to make this work because mine fits perfectly, as it does for at least two other users on this forum. S38 brackets mount directly to 535i pump, and in turn back onto the block's bracket.
