ALL 'L' series engines and the 'KZ' are s*** engines.
but don't take my word for it, go buy one but do take this advice...
make sure you have enough in your account for:
a new head ($4K installed)
upgrade the rad,
water pump,
exhaust sizing.
the tow bill
the motel room (since the head never fails in yoru driveway)
the fuel economy sucks
the power sucks
all in all, you will be a very unhappy individual.
but in reality what do i care, it isn't my frustration, my money or my happiness that will be affected. so please do go buy one and be another of the HUNDREDS that have thrown good money after bad.
Toyota did make a lemon... notice, Lemon starts with an "L"? ever wonder why?
