Hi all I've finally decided to make the move to turbo my series 2/3 au Falcon but I'm confused on a few things....I've read I can't upgrade injectors or have external waste gate...had any one been through engineers in NSW that could clear things up...my plan was to use a t66 or t70 turbo heat sheilded and mounted lowish.. recirculating bov with water injection and air to water intercooler..going for as stealth as possible till on boost..standard air box..all tide together with a j3 chip which will be dynoed and dynoed again till tuning is spot on...stock bottom end hoping for 10-12 psi..I have a 2.5" exhaust will go 3 once engineered...so that's my story lol who has certs and what's the biggest problem/muck around...
