Your 2000 Civic DX has D16Y7 engine (I think). These are the specification for it:
Displacement: 1,593 cc (97.2 cu in)
Bore and Stroke: 75 x 90 mm (3.0 x 3.5 in)
Compression: 9.4:1
Power: 106 hp (79.0 kW, 107 ps) @ 6200 rpm
Torque: 103 ft·lbf (140 N.m) @ 4600 rpm
Redline: 6800 rpm
Rev-limiter: 7200 rpm
Valvetrain: SOHC (4 valves per cylinder)
Fuel Control: OBD2 MPFI
Head Code: P2A-2
Piston Code: P2E
ECU Code: P2E

The F series engine mainly used on Accord with automatic transmission and lot of people considered a "Big block" on Honda. These are the specifications for the F23A1:
F23A1
This engine was used in the Honda Accord EX and LX
and Acura 2.3CL in North America.
Specifications
Bore x Stroke: 86.0 x 97.0 mm
Displacement: 2254 cc
Valve Configuration: SOHC 16 valves VTEC
Compression ratio: 9.3:1
Max power: 150 hp (112 kW) @ 5700 rpm
Max torque: 152 ft·lbf (205 N m) @ 4900 rpm
The F23A4 is substantially similar
but features ULEV certification with a slight reduction of horsepower: 148 hp (110 kW) with a maximum torque of 148 ft·lbf (200 Nm).

If you know what you're doing and has enough money in a reserved wallet. Anything can be done. Just remember you can't put an older engine into your 2000, for example any OBD 1 engine series (It's illegal) I'm not sure which Civic generation your car belong to (5th or 6th?) so I included both generations.

There are plenty of free guides, manual or blogs on the Net. Spend sometime searching for it and do a lot of reading will save you the headaches and avoid the pitfalls. That will cost extra money unnecessary. HTH

The most common engine swaps are the B16A (Civic SI), the B18C (Acura Integra GSR), and the new powerful K20 (02-11 Civic SI (except for the K20A3 from EP3 Si/ RSX base) and 02-06 RSX Type-S)
