Because there is sooooooo much work beyond just getting a new rail - you need an aftermarket FPR, new fuel lines and a way to route them including all the associated fittings. This quickly adds up to high cost and complexity.
I'm working on redoing my fuel set-up right now, using a custom secondary rail and Bosch 1600cc injectors.... Believe me, if you don't need the extra fuel that 1600cc provide, do something that utilizes the stock fuel rails: either 1300cc seccondaries, or modify your primary rail to fit 850's.
Not to mention, how will you acurately control your secondaries??? If you are running the Power FC, it will only accept up to 1300cc secondaries, unless you are using the datalogit software....
