Nothing wrong with power steering on a drifter.. May need a cooler if the fluid boils but other than that's I'd keep it.. I ran a sierra with welded diff for a year, was pretty shit tbh as far as a drift car goes, and I also had a 200sx for 6 months that was far better std than the modded sierra.

Unfortunately with six, skyline etc is the insurance kills it.. Mx5 are a very very good handling car if you can out up with the gay/hairdresser jibes. Even the 1.6 motor has a enough poke if you have some skill.. People think you need power to drift, you need skills more!!
