Regarding engineering you'll have issues with the following:

  • Vented Bonnet (especially if fibreglass and not ADR approved.)
  • Carbon Fibre Mirrors (Same deal, if not ADR approved)
  • Race Seat (Again, issues if not ADR approved)
  • Gauges (depending on placement)

These are particularly difficult due to the costs involved for the tests if they are not ADR as you'll have to foot the bill proving these meet the ADR requirements, whether they pass or fail.

ECU, turbo, etc is fine if you pass an IM240 test.

Oil cooler should be fine.

BOV is fine if it doesn't vent to atmosphere.

Front Facing Plenum I would have no idea on (this might come under IM240 and review of piping placement)

Airbox - as long as it is covered. Can be a sticking point as some may say it needs to be covered when the bonnet is open, others is fine if it's enclosed with bonnet closed.

I am not an engineer but I have done a lot of research into RMS Engineering, the ADRs and talks with engineers on testing requirements, process, etc.

Hope the info helps.

    • From the pictures I have when doing the job the flywheel is the same diameter, I don't think they're playing weird tricks like putting weights at the outer diameter to increase flywheel inertia or anything like that. The OEM flywheel is definitely heavier, but it's not a huge difference. Quoted weight savings of the clutch is 2 kg so I can't imagine the flywheel being lighter than ~7 kg. Kind of regret not weighing it before the clutch went into the car but as far as driveability goes I have no complaints.
    • HKS trigger kit should be very easy to integrate with a Link. It's a 36-2 crank trigger. Hard part is finding the motivation to take off the timing belt and everything on the front of the engine to install it. You also need to cut out a hole in the oil pump housing so the sensor can read the trigger wheel. Changing out the cam sensor for a 24 tooth setup is probably good enough but as others have mentioned depending on what underlying assumptions are changed it becomes more of a problem. Reading the crank state off of the cam is an abstraction that works in the general case, but if you have an edge case it makes less and less sense. There is a GTX2860 gen 2 that can take a compact 5 bolt housing so it's direct bolt on but I'm not 100% sure of what's involved. Peak compressor efficiency drops off a bit on these turbos vs -5s, 77% vs 73% but you get way, way wider region of operation. The -5s have a really strange surge line in their compressor map that is all over the place. If you think the hot side on the -5s aren't open enough you can try the Tomei T550B turbos which a local tuner seems to be happy with:
