The mk1 SC is a great car, they are about as quick round a track as a mk2 turbo (stock). The SC can be tweaked to about 220bhp, which is plenty for a car so small. The Gen 6 Celica ('94+) is a 2.0 engine (3s-ge) and will fit, but as they are only ~160bhp there really is no point. And if you want a celica with a 1.6 SC, have a look for a Levin as they have the same SC'ed engine and are the same size as the celica ..
