B&M I think is the best but any short shifter that lets you shift gears smoothly and quickly without the delay and letting back pressure get to the turbo in between shifts is great all i care about is when I shift out of 25 psi at 8000rpm I want it to be right back into like 20psi in the next gear oh yeah and mine is on a ka tranny now too with a SR bell housing works great and you can get the tranny's for like $50
