Of course, getting the first-generation JDM Si CRX front-cut is a nice option. 130bhp of ZC goodness and with a front cut, you get the loom, ECU, drivetrain, brakes etc
I went for a ride in an imported JDM Si third-generation Civic - damn it was nice, the ZC pulled the thing along almost as well as the B16 in a 4G.
