Comparing the K20Z in an FD:
K20Z2
Displacement: 1,998 cc (121.9 cu in)
Compression: 9.6:1
Bore x Stroke: 86 mm x 86 mm
Power: 155 hp (114 kW) @ 6000 rpm (SAE net J1349 Rev 8/04)
Torque: 139 ft·lbf (188 N·m) @ 4500 rpm
Redline: 6800 rpm
And the B18C2 in an EG sedan (balance the weight issues out)
Displacement: 1,797 cc (109.7 cu in)
Compression: 10.0:1
Bore: 81 mm (3.2 in)
Stroke: 87.2 mm (3.4 in)
Rod Length: 137.9 mm (5.4 in)
Rod/Stroke Ratio: 1.58
Power: 170 hp (127 kW) @ 7600 rpm
Torque: 128 lb·ft (174 N·m) @ 6200 rpm
Redline: 8100 rpm (Fuel cut-off @ 8200 rpm)
VTEC Engagement @ 4400 rpm
VCIS Engagement @ 6000 rpm
Then calculate the curb weight (EG is 1144kg, FD is an estimated 1300kg)
So the EG has 148hp/ton and the FD is 128hp/ton. For torque the EG has 152N.M/ton and the FD has 138N.M/ton. On paper the EG would eat the FD2 on the straights in pure power-to-weight ratio, but when it comes to cornering I think the FD has the upper hand, due to stiffer chassis and a modern suspension setup (independent rear wishbone suspension and a much better Macphearson struts up front).
