Crank: Honest save the money, and go with a balanced stock crank.

Bearings: Nothing but ACL's

Con Rods: Corrillo rods are light and durable, plus I know a place that sells for close to manley I beam prices if you have them build your motor(which I'd recommend)

Pistons: 8.5 cr JE FSR. Had lots of good experience with JE pistons in other applications and from what I read here they seem pretty awesome. Though if anyone has a suggestion on a lighter but equally robust piston I am all ears or if 3MI releases a piston I will go with that. Also looking at stock piston bore size to start out because more chances for hones later. Good choice but I'd do minimum of 9:1

Gaskets: I'd just do copper sprayed stock head gasket, works all the time.

Heads/cams/valvetrain: There are tons of heads out there that flow better and cost less then cosworth. There cams are just whatever too, I think kelford and GSC make ones that walk all over theirs

Intake manifold: building my own out of carbonfiber composite, I have many years working with CF in sailboats and also in acoustic products. Also have lots of experience in CFD so I think I would rather try this one out on my own. I of course will be sharing what I find and anyone willing to offer advice and help are more than welcome to. I will do a separate thread for my intake manifold. Interesting to see

Headers+exhaust: custom equal length inconel headers and down pipe, ewg (twin tial 38mms should do it), titanium cat back. Inconel, that will be expensive

Throttle body: skunk2 72mm dbw

Intercooler: spearco custom air-2-water. Lighter, colder, less piping, plus unique, will put a water reservoir in the back. Not sure if I have seen a air-water that weighed less then a air-air, not ideal for street duty

Turbo: I think you'll find the .92 a/r housing will be a choke point.

Other then that I think you will have a hard time making that amount of power unless your doing it on a dynojet with good fuel.
