Depends on how much H.P. your going to have. If you will be relatively mild you can pick up a T-5
from a camaro,mustang, or others relatively cheap/ I did it with success. Later with increased hp, I went to a Muncie M2Z, rockchrusher. about $4-500 darn difficult to tear up.
If you want 6 speed, be prepaired to spend some bucks.
