Did some reasearch on one and came up with the following drift spec:-
I would stick fairly standard and go for lightening the car - this has better dividends in drifting. A limited slip diff 2 way 4.778 final drive would also be needed. You could add an APEXi SAFC II fuel controller too.
AE92 big port engine (red top) Toda cams 304/288 duration 8.5mm lift.
Toda adjustable cam pulleys, NGK R plugs, OER Quad throttle body kit with pipercross or K&N Filters.
Exhaust - Trust DD exhaust.
Tein coilovers front on the rear use TRD blue SS 8 way adjustable shock.
Hope that helps out a little?
