For the 01 Integra motor (OBD2), you will need an ECU from from an OBD2 Honda/Integra. If you are going to use the GSR head, try and find a 96-01 GSR ECU. You can convert to OBD1 (92-95 motors), but this will require an OBD2-OBD1 conversion harness. If you did this, you could use the p28 ecu off of the 92-95 civic. This is a popular ECU choice for people with OBD1 setups. There are a variety of chip programs that work well with LS/VTEC's.

Go over to this forum and do a search. There is some good info on this site for LS/VTEC's.
