alot of turbo 240sx's have MAJOR traction issues if they dont have an LSD. R200 diffs are cheap to come by though, there are plenty of cars where they can be had from.

also, 205 hp at the crank isn't really all that much for an s13, and 220 isnt that much power for a s14. The power/weight ratio on both cars aren't far off of eachother if you think of it like that.

also, the type-r tranny is a hardcore racing tranny with near perfect gearing. after the mediocre fwd launch, it will start to shine in second gear, and it will really shine in third gear.
