So yeah, list is as follows (probably forgotten some stuff)
Intercooler - removed or engineered (doing the latter)
ECU - SAFCII apparently non compliant, need a stock ECU
Turbo - RB30 bolt on is non compliant, need a stock Turbo
Window Tint - since the car was ADR complied in 2000 its too dark, needs to be removed
Suspension - Bilstien coilovers need to be put back to stock ride height
Exhaust - Needs to be put back to stock, otherwise the car would need to go down to the EPA join in Penrith and tbh, f**k that
Pod filter & BOV - obvious ones, but least of my worries
So yeah, if anyone has a stock exhaust, ecu and turbo lying around for sale, please let me know.
