I have a m3 that was converted to evo. I run the 22 rear drive pulley and 51 rear axle pulley I put the fm644 sp belt that the manuals say should be the right belt , but the belt is too long I had to dremmel the ecentrics to make it work. two other belt that are possisble fm379b and fmw9b which are 201 teeth the fm644 is 210 teeth what part is the wrong one and if the fm644 is the right belt which pulleys are the right ones for the evo the manual says 22 but doesn't give the rear # any help thanks

For the EVO the correct gears is the 22t front and a 51t rear with the 210belt. I could never get the belt to be in a tightend position but never had a problem with the belt slipping or stripping even as loose as it was. If you want to feel more comfortable you can use the pulleys and belt from the m3 which is a 20t and a 49t with the 201 belt.

thanks eric, I feel more comfortable with a slightly tighter belt so I will just run the dremmeled bulkhead

When using the new M3 EVO rear pulleys, you need to use the optional eccentrics, otherwise the 51T pulley will sit below the chassis.
