I agree, but seems like the 5 speed Passon is unavailable, so it boils down to what is the car being used for, and how much money it will cost, and skill level for the install of a TKO. If it is a manual already, and if a Passion 4 speed is good enough, all is needed is an 18 spline clutch, then plug and play. On my 4 speed at 2500, I get around 75 mph with 3:54 gears.
