Hey Guys,
Has anyone fitted the e34 M5 plenum to an s38b35? Is it worth it?Aside from having to move the coolant resevoir, what is involved in fitting the plenum from the E34 M5 models? Can it be done easily enough? I noticed in the etk that the plenum controller requires some sort of vaccum tank to open and close the flap. Is that something that must be retrofitted?
