If I were to do the swap on a 1G I wouldn't do it to stock MT parts though, I would upgrade from there(2G exh mani, 550's or bigger, 16G or bigger, EPROM ECU). To me it doesn't make sense to upgrade from AT to MT parts while doing the swap unless any of the parts were bad or you had a good line on those parts for cheap and working well.
