The SC61 will also have considerably more lag.
Not to mention a higher level of difficulty and price getting it installed on your car..
The extra $400 dollars gets you a turbo that bolts on to the stock manifold. You'll need an install kit from Frsport.com for the 2871R to be a bolt in affair. If you go SC61 you'll need a Top mount, custom downpipe, oil/h2o lines and most likely an external wastegate. So in the end you'll end up spending more money to get the SC61 installed vs the 2871R. It all depends on what you want from your car. Personally I like a fast responsive car, not a lag monster...
