We've done more than our share of 1994 Turbo 3.6 builds. Your goal of 400hp -- even 400rwhp -- is really easy to achieve. Based on past dynos, it'll probably do 400hp at the flywheel around 0.5bar boost, and about 400rwhp on pump gas at stock 0.8bar boost pressure.

You've got a lot of the right ingredients already, off to a great start: rods, head studs, ported heads, cams, headers.

If the car is mostly for the street, the only think I'd change from your current list is maybe the cams. The GT2 cams don't have the best idle, nor great manifold vacuum. Consider a cam with more lobe separation (SC, 964, etc.)

The 964 plastic manifold works great, especially with the simpler round 1992-95 throttle body. Be sure to examine the injector bases, and use all the rubber manifold couplers from the 993 Turbo (fiberglass reinforced). Use the resonance flap -- greatly improves the torque.

Wastegate -- stock 930 if you have it and it's in good condition, otherwise Tial 46 (bolt-on)
Blowoff valve -- 2x stock 3.6T/993TT, or 1x aftermarket
Stand alone ECU -- AEM, Motec M84, MS... what your tuner -- or you -- is comfortable working with
Injector size for 400-500hp with being street-able -- Siemens Deka will work perfectly, fantastic spray pattern

And an intercooler. For your power levels, a stock C2T intercooler will work fine, if you have one. They support ~470rwhp. You can try to modify the manifold's center plenum (ala Ruf RCT) or re-fabricate the intercooler's outlet tank. A Garrettson/Andial intercooler will work, too, and can sometimes be found used to save you $.
