I don't know if the I4 and V6 share the same transmission or not, but I can comment on the TWM Shifter though. With the bush kit ($19.95 when bought with the shifter) the short shifter kit is an excellent buy and reduces the throw by a fair margin (apparently 30%). With a weighted knob as well, shifting at speed is not an issue. Stiff and smooth. Bah, can't sleep in anticipation of the Stage 1 install. Going to be a long 3 days I think. 2 days to install, 1 day of lots of driving. on the TWM website it doesn't say anything about what motor so it might fit were did you get yours from and how much oh and do you know if the standard gear knob fits? Further communication in PM. Stage 1 of the supercharger install is complete. Biggest issue of the day was the bleeding of the new brake setup, the clutch just did not want to do what it should have done. Used an extra 500ml just getting it right. Everything is ready for tomorrow however.
