I can't speak to the 4* personally but I really think you are going to be pressed for room. I gathered up all the components for Minn's smoke system to put in my Dragon Lady with a Saito 100 in it. After hours of trying to place everything in every location possible I finally gave up on the idea. There just wasn't enough room for it all without becoming a cluttered up mess & getting in the way of all the components that were neccessary. A lot of the problem for me seemed to be the fact that the Dragon Lady has that rounded fuse making it hard to mount extra stuff in there, but you are talking about a fuse that is a good deal smaller than the one I was trying to set it up in. Good luck, I do hope you can find a way to fit it all in & get it to work effectively for you. I decided to just scratch the idea for now & save all the components for when I get my 1st gasser. Something like a 27%er or better!
