The type SH has most of the modification problems because of it's large transmission. Running the downpipe and oil lines is why the Greddy Turbo Kit doesnt work. F-max would probably be the next best kit without making custom piping. I think it uses the Garrett T3/4 turbo, but the advantage with the F-max kit is that it comes with the intercooler. They dont do a very good job with placing the extra injectors and the piping isnt as good as Greddy but it would be less hassle and less expensive then the Greddy. The F-max kit will run you about 4000 give or take some, then installation if you need. The ATTS becomes a problem when you're making somewhere to about 250 to the wheels, then your ATTS light will come on and may not function. The tranny swap is a good idea, but will cost you. The F-max is probably the best way to go for the SH models if you've got about 4G's to drop, but it's the only way to make real power.
