I have a 01 Sunfire 2.2, and I want to convert it to a Manuel Transmisson. Im wanting to know how easy of a job this is, and what manuel transmissions will bold up to the motor..

Yes it is possible... but it would be TEN times easier for you to just trade in your 01 for a new 03 w/ a manual.... or another 01. Because its not just a simple, "slap that puppy on der and shuv a stick up thru ur floor" You also have to cut your fire wall for a clutch, and if you dont have your engin completely out of the car this will be close to impossible.
