1) Passed the pits with my VR4 on D2 coilovers and he didnt say a thing (o'connor) - and they were bright purple :O! - they were more concerned about exhaust & oil leaks.
2) Bracket sounds easy enough, what about it not having a AFM/
MAF - I assumed it was something they'll look for with regards to emissions.
3) Looked like stock standard tint
4) Was apparently recently rebuilt and after leaving it to run for 15min when checking it over, there wasn't a drop of oil to be seen - trust me i was surprised!
I guess its like i've seen over heaps of threads similar to this it really depends how nice/blind the pit inspector is.
Thanks for the advice Voot/Kato really appreciate some direction on this - I do wonder if it would be cheaper in the long run to get a stock manifold, turbo, exhaust and air box to get her over?
