I'm sure Kevin can agree with me on this. The Hachi is a blast in stock form! Beef the suspension, install a good LSD, 4.7 gears, W series trans(longevity), the T series is an adequate trans though). Build the engine to @175hp @8500RPM. Lighten the car. Most of the non pro drifters are running this level of tune. 300hp is a bit much for the light frame. More likely than not, detrimental to the handling, it'll twist the body too much, and the suspension really isn't designed for that type of power. Remember that the little car that could, could due to the balance of power, body rigidity, suspension and weight. Throw away that balance and you've trashed the car. Best I ever saw was a Honda S2000 engine/trans(stock tune) in a completely done suspension, caged, welded, lightened 86. Oh yeah, when you get to this level, you have to use GOOD tires, not just street tuner tires, but track tires. Regular tires will last as long as track tires, if you get my.....uh.....drift. Yeah, massive power is as LOT more work than it's worth. The 86 is a living 'less is more' philosophy.
As far as the 2ZZ, not really sure if it is adaptable to FR. SR20, F20, GZE, 2JZ, 7MGTE, RB26, RB25 are all FR set ups, and fairly easy to adapt to the 86.
I really do miss mine, wish I never sold it. Sorry Kevin.
