You don’t need a FMIC, just get a whole clip which will have mostly everything you will need. (Smic and ecu), and I’d just recommend picking up a walbro fuel pump which is like $100 - $120 brand new. And if you don’t have an exhaust, this will be a good time to pick one up. Oh and you’ll probably need a downpipe which is around $100. You can also get a turbo elbow which might be $100 or less.
But yeah, I’d also recommend doing the clutch since the tranny will be out.
