Add to that an intercooler, making for a denser charge, your boost will drop at least 2 psi. Increasing boost without significantly increasing fueling will not produce any appreciable power, it will increase your EGT's though.

Your base engine has a lot of room to play with performance wise. You can go crazy with it and get north of 300hp. There are many sources for performance upgrades namely in Europe, so modifying it to suit your needs should not be a problem.

At the moment, the greatest limiting factors IMO is the packaging. It still has to be fitted to the Disco, and that will have to be accomplished prior to making other commitments to the engine, as the packaging will dictate your exhaust, intake, intercooler plumbing etc. Without the packaging being completed, this will be very difficult to plan for in advance. Once installed and mated to your existing trans, xfer and gearing you will have better info as to what works well with each other and where tweaks could be made to the gearing or the engine, or the engine's ideal powerband for your specific setup.

I'm sure that the Landie world has some great insights into what others confronted in their swaps. Hope this helps you somewhat.
