I assume you are going to raise the boost somewhat.  There are stages
of what you can try -

  *  A changed wastegate spring will get you from 1.3 BAR to 1.7 BAR
     which has noticable results.  That's going from 5 PSI boost to
     about 11 PSI.  I've got these for $35 with instructions.

  *  A wastegate spring and ECU modifications can be even better.  Try
     Ben Swann at benswann at comcast.net  I think he is doing ECU upgrades.

  *  Another source of ECU and turbo modifications is Intended Acceleration,
     see http://www.intendedacceleration.com/

When you are planning the 4000 instalation, leave room for a big intercooler.
That will let you run more boost than otherwise.

Going further can include turbo swaps, and different fuel injection.
Before you go too deep (read: expensive) with an MC engine, I'd recommend
that you find a 20V engine complete with it's ECU and wiring harness.
This engine has the potential for near 400 HP before you get into engine
internals like lower compression pistons and forged rods.  Remember
these engines reached into the 600+ HP range for European rally cars.
