I haven't done it recently (just looked it up in my maintenance log and it's
been almost 10 years!) but at the time it cost $150 from Ricambi so I'd 
expect it to be about $250 today. The "minor modifications" involve the 
pump mount and routing the hoses since the Bosch connectors point in different
directions than the SPICA. This sounds like a major deal, but it's not too 
hard. Also, you have to replace the exit orifice in the FI pump which controls 
the pressure on the inlet side of the plungers. It lives under the forward 
hose connector on the FI pump. The Bosch pump has a much lower flow rate 
than the SPICA fuel pump so you've got to reduce the orifice size to keep 
the pressure up where it needs to be. You can make one yourself from a metal 
blank with a fairly precision hole in it. I don't recall the size, but it's 
pretty small (on the order of .050" or so).
