I just went with this intercooler per Andreas M - Ill post my progress as I get it posted if anyone is interested.
EVO Intercooler which is suppose to work great for piping on our cars.
Overall size: 31.38" x 15.35" x 5.31"
Core size: 19.33" x 11.42" x 2.7"
Inlet/Outlet: 2.5"
Will just require cutting off the EVO mounting tabs and welding up your own.
