I keep going round the houses on this one but then my expectations differ from most

Given the car is in fine cosmetic order and with fully re-furbed general parts etc .
The options need to be expanded upon so here goes .
OE is self explanatory
Mild is higher lift cam , turbo to suit ,bigger injectors and Renix remap .
Modified .As above ++ ,exhaust headers ,changes to turbo plumbing and starter and standalone management .
