WRX Subaru 2.0 Turbo- intercooler questions

[Trader4Less]

I put a 2.0 turbo with an upgraded turbo in my street legal Manx. I planned on adding an intercooler and larger fuel rail. Any ideas of what the best set-up and the cost would be? I researched the fuel and I found out that 40 pounds is the norm and that a 55 pound fuel rail with the intercooler is the perfect set-up... any ideas or additional info.

Thx, Manny
