First of all welcome.

Second of all, please re-read things before you press post and have a look at formatting. Tax payers have spent thousands of dollars on schooling, please use the skills that have been given to you.

To answer your question, I think, to pass rego all of those modifications look stock. the inter cooler and turbo they wont know the difference. The fuel lines will be fine also. They look for if the car is roadworthy. Oil leaks, exhaust etc

Congrats on buying a good car by the sounds of it. Pictures say a thousand words.
