    Need room for brake booster; don't want to modify firewall

    I am doing a S38 swap into my E30. I have a M5 booster but I am tight in room and thinking of the idea of using a hydro boost system from an M30 powered E24 or E28. Has anybody used this type of brake booster swap? I was thinking this could be a good option due to space savings.

    It may save a little bit of space, but you're adding a big valve block, more hoses, accumulator (nicknamed "brake bomb", go figure), and creating a messier engine bay. I'd recommend an alternative OEM booster.

      Why not the modified e21 booster instead?

        E21 booster fits and clears, but may require remote mounting the fluid reservoir. This is the best plan IMO.

            Any idea of the size difference between a E34 M5 booster and an E21 booster? How is the performance difference? I have the E34 M5 and it looks like its a tight fight and would involve me removing the S38 Intake plenum which I would rather not do. What about those dual cylinder brakes without a booster, I believe somebody on here made them, can't seem to find the link. Any good?
