So basically, if I like low-end torque I might as well be happy with my
K24 as that's as good as it gets?  It already has shit for low end
torque, wouldn't want that to get any worse.  Damn, I miss my small block
V8 LT1 Trans Am then (burnouts at 1/4 throttle in 1st were nice).

Come on Scott, you're a fellow hick like me - why do you even bother
driving these things?  AWD?  Mine's just a good all-weather driver with
some passing power on the highway.
