Hey, try and find a mazda 323 GTX that has bad body damage, u basically need all the engine, ECU, wiring loom ( cables)
If u are 100% sure u have the G series ( as some 1995 models have thr F serieis) then all u need to do is swap the engien over, get a new clutch ( GTX one or better 225mm) and remove the old BP ECU and loom. U will also need a new Intercooler and plumbing pipwork

have aread in the F.I section there is lots of info, also havea look at my conversion thread.
If you need to chat my msn is
