wow taka... im surprised the old RE-01's hung in there that well. sounds like it was wicked fun. i would suggest sticking with a 4G motor too... they are easier to work on than the EJ's...
actually, you COULD import a 1G DSM... set it up for grip quite easily. there are coilovers available for the 1G DSM's and such. add a welded center diff and it should be able to oversteer when you want... especially with a feint.
you could also do a Starion with a 4G63 swap... however, the obsolete steering setup on those cars is not very good for quick inputs. IIRC, its not rack and pinion at all. you could always do what id like to do: 4G63/R154/FC3S

add a custom Eaton M90 supercharger and have instant torque
