I have, worked out nice. Mounted on frame rail by alternator. Below intake pipe, pointing down

Most SC300's were auto also. The manuals were very rare......I am not sure if the trans. would swap between the 2 motors. Good question though, hopefully someone would have some insight on this. My take is that they would not be swappable. Y not get a sc300 with a 1jzgte or 2jzgte already in it with a 5 speed. That way, you get the power you want and the manual trans. There are a couple being sold on 2jztrader.com right now you may want to check out.
