saintlucifa 0 Report post Posted April 19, 2004 Could anyone tell me if it would be a straight swap conversion to use an E34 525i 2.5L gearbox/clutch-system/pedelbox/driveshaft etc to swap into either an E34 535i 3.5L with auto, or an '83 635csi 3.5L auto ??? Are they the same 5speed gearboxes on both engines? Thanks Quote Share this post Link to post Share on other sites

318i Turbo 0 Report post Posted April 22, 2004 the hardest part of the swap is rewiring the switch thing in the auto shifter that allows u to only start the car in park or neutral so u can start the car once u have the manual in the car Quote Share this post Link to post Share on other sites
