the 4x4 has been a dream! hardly any trouble, only the turbo giving up 1 fine day!

here's me spec:

worked head (ported, polished, gasket.......)
chipped
full 3" exhaust system
low comp pistons
greys
t3.5
forge intercooler
32psi

ran 12.4 @ 111.5mph

(only changed the gearbox somewhere close to 10 times and diff about 6 times )
