Running the T40 is fucking stupid, but I needed the car running again after the T50 blew and that's all that was available. It's been 18mths and I still haven't found a T50 that I'm comfortable buying.
Pretty much sit on 4000rpm at 100km/h, so short trips on the highway are bearable but not too fun in summer. I did drive it to Mullumbimby and back for Cusco camber tops though...
P.s. Smallports are awesome!
