I have e-mailed them as well. Everyone is back ordered. So far the ETA has ranged from 30 days to discontinued from stock.
My understanding, someone correct me if i'm wrong, is if Autech or Nismo is not making them there are not going to be anymore. So your next best bet is paying the $750 from Kelford or pay out the nose for some customs. I don't think there is anything you can even regrind to get the profile of an N1.
All in the name of performance right?
Maybe someone should contact Kelford and see if we can get a group buy
