That turbo comes with the engine, I only needed to modify the inlet fitting by 90 degree (it used to point backward to the firewall for the turbo fitting and now I have it pointing toward the intercooler).

The process quite straight forward:
1) Measure the inner section of the intercooler (only the core area)
2) Cut the hole on the bonnet with the area above ( find the right place in engine bay first to see if anything will be on the way first of course -:)
3) Close the bonnet then get the string to mark left+right cuts then front+back cuts so you have 2 marks on the guards and so on...
4) Open the bonnet use masking tape to join the marks and the small area enclosed by 4 lines in the middle is the bonnet scoop hole.
5) I used temporatory brackets to hold the intercooler up then adjusted the gap b/w the bonnet and the intercooler, I then left those brackets in place and made the perm ones to secure the intercooler in place.
6) Finally the pipes.

The whole thing took about 5 hrs for me (excluding 2 hours to weld the aluminium inlet then file it down)

By the way, I just got back from a long trip today. Fuel consumption seems to be better as well, I got 620km from ~52L of diesel, mainly on hwy at 100km/h
