Get B234FT in and it is going to be big drifts, of course that engine needs bit more boost
With stock B200K it is not going to be very good drifter, at least cam is needed to be changed (stock cam is for torque, above 4000rpm it is useless) and carb need to go, twin carbs or fuel injection.
Put those caravan(strenghtened) springs to rear or Lesjöfors lowering springs, maybe helps bit with understeering, stiffer ARB to rear is not bad idea also.
