Best bet for this is Devonmikeyboy or Devonutopia. Both have done a lot of engine work, including rods, injectors, headwork etc.
 
Your talking lots of money to start doing engine work.

Dibilas Cam or Colt Cam
Ported Head from Jabba
Rosten Rods
2.0TDI pistons
bosio injectors or Firad injectors...

thats 4000k just there.
