This is a great thread because I'm am in the exact same host as the op. I even have an FXT as well.
I've done a fair bit of searching as I'm planing a turbo upgrade soon and would love to take advantage of the better priced turbos that work with rotated setups as well as ease to work on. But I also want to keep a tmic setup.
You can pick up a turbo xs kit of just the up and down pipe new for a fairly good price but I feel that setup might sit the turbo to high to plumb to a tmic. Perrin told me there to setup will work with tmic and you can buy just the up and dp. The also told me there new intake was made to be Maf based and has inlet to plumb you bpv back into so that takes car of that.
If you google "sti rotated adapter" a thread from itwsti will come up with a vender that makes a rotated adapter to a stock uppipe to help cut cost.
It would be great to see some pics of some pieced together setup of the tubing from the turbo to tmic.
I'd love to figure out a good plan and I would totally take the rotated route.
