    Critique my S50 parts list!

    I'm getting ready to tackle an S50 swap on my 91 318is and put together a parts list of stuff I need, so I just wanted to run it by some of you guys with experience and see if I have everything covered, let me know.
    Thanks.

    1990 S50 goodness.

    Booster: Dont bother with the THR one, either mod one yourself or buy an IX booster

    ECU: If the ECU is a 506(non ews s50) then yes you reuse that, otherwise you either need a red 413 with a chip or the silver 413 with an ews delete chip(non prefered method)

    Adapter: I would have greg modify your harness for much cheaper

    Motor mounts: Use e28 green hex mounts and save some $

          I was under the impression you could use the stock driveshaft.

            There is an IX booster on ebay right now for stupid cheap.
            You going to need a master cylinder for it too.
            You can buy new e21 boosters from autozone for cheap and use your stock master and res. in the end it comes out to be the same amount of money as the IX setup.
            MrEricT on here also does a harness mod and adapters. He has done many and very cheap. Id look into him also.
            The e28 green mounts suck to be honest. I have seen many of them split and the studs break out. The black ones seem to hold up better for some reason.

              Yes if you use the 260 that's true.

                I got a 7 series booster at the junkyard for 25 bucks just need different MC and extended the push rod with a piece of metal from hardware store. I would try a good junk yard before buying a mod booster for $329.

                      I would buy AKG swap mounts. Broke more then $200 bucks worth in e28 green mounts, just not worth it.

                        What brand mounts did you kill?

                            Somethings not right there. I never see those mounts go bad even when people beat the S out of a E28 with a much heavier engine for years and years. Are you buying Lemforder and are you sure the mounting surfaces are parallel? That mount should NOT break.

                              it is one of the most important things to have for the swap.
