Just about any V-tech motor 1.6 and above will be able to get you almost the same power as the celica motor and at a fewer RPM. If you want something thats already been done with the same power, you could look at a K-series or H-series swap that would easily outdo that celica motor any day of the week (not so easy to put in, but powerful) . If you want even easier, you can look into B18's or B16's, there should be one of those that matches your power needs. and all the motors above should have some sort of mount kit already available.
