Is that a tuned chip or just EWS delete? I have a TWS chip that is tuned for the M3 exhaust and lightweight flywheel with EWS delete. Anyhow, it should work, but the Getrag 260 comes in 2 flavors - shallow and deep bell housing. You can use an M20B25 flywheel on a deep bellhousing trans with a custom pushrod, and you can use an M20B20 flywheel on an M50 with a custom pushrod, so it should work. Again, this is the sort of thing that has to get figured out that can take time and therefore money. I wanted a 12lb flywheel on my M50 so I opted for an M20 flywheel of secret part number, but then had to use an M20 starter (I was surprised by that one) and a custom pushrod.
