    From what I've heard it's not woh the hassle or $. Likely better to just look for a 6MT model to buy or trade into. Mind if I ask why you're looking to swap into a 6MT?

    OP -- I think I remember seeing it cost somewhere between $6-7k to do an E90 trans swap. If it's going to be a track car, you could prob cut that cost down since it won't need OEM-like appearance (assuming the interior would be gutted)

    Not a bad thread to have around with the couple st guys with 6at's thinking about the swap. Has anybody done it yet? Off the top of my head the parts list would be something like; trans, clutch/flywheel, shifter, Clutch slave, clutch master, possibly driveshaft, pedal, shift boot, plus some small stuff here and there.

    That's about what I expect the list to look like as well. According to RealOEM, the MT also uses a different wiring harness than the AT. The good news is, the portion that is different appears to actually be a sub-harness (not the entire wiring harness). There is a P/N for that sub-harness and price is relatively cheap. That probably connects the backup switch, clutch pedal switch(s), and the DME. Also, I see no need to remove the AT sub-harness; just unplug and run the new MT sub-harness next to it.

    Oh, here it is:

    I don't think that complete list is required. The gas pedal for instance, I'm sure the only difference is the kick down switch for the AT and it'll probably work fine for the MT. I've got a buddy that wants to do this asap. He has a lot of sentimental value with his car and also plans to swap the turbos later.
    I'm thinking about 3-5k in parts including an aftermarket clutch and flywheel. When we start, I'll put together a build log and probably make a DIY while at it. He has another car to drive so I could take my time. I'll probably do the same to mine sometime next year and then swap my turbos as well.

    That list also specifies an oil pan; but when I looked on RealOEM, they do not specify a different oil pan for MT and AT. The oil pans seem to change with the chassis, though (e.g. E90, E92 and i or xi).
