Springs are probably not a bad idea although at that power level it doesn't seem like you need much boost.
I went with the 603 pump also but in retrospect erx probably has the right idea with an electronic pump, Ole controller running a larger VNT than stock, and Baldur's stuff for pump control. Then you have a pretty modern-ish setup with excellent drivability.
There isn't a whole lot of room for a big air to air but it would be easy to put some in-line axial flow coolers in and put little water radiators in the wheel wells.
Let me know if you would like to sell the pump from your motor :-)
