Getting the m52 off was easy (15 minutes)... putting the m50 on wasn't TOO hard... the time consuming and annoying part was modifying EVERY SINGLE HOSE AND CONNECTOR from the m52 manifold to the m50 manifold. This means a few trips to lowes, home depot, plumbing stores, and a bunch of other places trying to find elbows, pipes, t-pipes, and everything else with the matching diameter and such. There was a lot of custom work that went into this.
that why i purchased the conversion kit. my mechanic said that buying the kit made it cheaper because it did not require any custom fabrications.
time for some m3 cams to make that baby fly
