its not expensive, but it can get if you don't do it right, setting the timing chains in the right place can be a pain if you don't mark stuff off, putting the timing chains in a bad way will most likely bend your valves as they open at wrong time and hit the pistons as it is an intermitent(sp?, don't really know if thats the word...its something like that) engine.
and knifeedge is right......since the vlsd goes with liquid, then it takes more time than clutch type lsd's, the S15 comes with a helical LSD which should be a clutch type, should be better, but not many importers get those right, then there's kaaz and some other companies that make clutch type lsd's but are way.....expensive.
