Hi Ben, answers as follows.
79,445km total - I have the original cluster, the Nismo cluster was purchased new from Greenline and installed when the engine rebuild was done
ADR Modifications Pty Ltd, 100 New Street, Spotswood, Victoria, 3105 - they imported the car and complied it, odometer reading at the time was 69,865km
Suspension installed prior to engine rebuild, and it was purchased new from Access Autoworks (I have the receipts)
Turbos installed approx. 1,500kms prior to engine rebuild, and they were purchased new from Just Jap
The clutch was supplied new and installed by Racepace - I think it is an Exedy
Yes, the climate control / AC works well
Everything on the whole car works as it should
