If you're not looking to make 600+hp, the stock rods will work with ARP rod bolts.
Replace the pistons, or pistons & cylinders (there are very safe slip-fit 3.8L P&C sets, like we offer and use).
Replace the head studs (we use and sell ARP).
Add boost.

ITBs -- I can help you with that, have a set available complete with plenums, or can make a new system for you. And yes, it'll rev like a motorcycle and let you run some huge cams for big, broad power that otherwise would not work on a single throttle intake manifold.
The 993 3.8RSR throttles don't bolt up, different 3-bolt pattern on the RSR heads and wider port spacing than street heads.
If cost becomes an issue, though, the single throttle body 1995 intake will easily support 700hp and leave plenty of room for a big air:air intercooler (unlike the VR manifold which leaves very little room).

EFI -- Motec, AEM, Autronic... as mentioned above, think a lot about the support you'll need and can get, especially if you plan on doing all the installation & tuning yourself. We use AEM and Motec.

Also have an almost complete twin turbo system available. Give me a call if you are interested.

A properly designed single turbo system will save a lot of money and fabrication and can get you nearly the same low rpm torque.
