For the ppl to talk to over hear in WA
either GtrKen from hyperdrive ems or SST Steve from SST automotive. Both know their stuff.
As for ND4SPD - Thing has impeccible manners for a 800hp (engine) car. Idles well, uses less fuel then a stock GTR when its being driven normally (which is hardly in Ants case ). Thing is daily driven and has no problems at all running on the Wolf.

As for the price, wolf comes in cheaper then that Autronice, but thats a bloody good price.
