extreme custom engineering - Craig the guy who ownes it built my bottom end, ported my head, made my exhaust, made my olf front mount, and piping..and does heaps of custom fab work for Anthony Kellam, and John Dual (sorry if i spelt your last name wrong!)
only guy i know who can weld this neat.. here is a manifold he made for Lochlan (ae86 lover) at triple 999 automotive, does most of their fab work too, also if you have seen a turbo conversion done on a car from brisbane turbo and tuning, 99% chance Craig did it..
