I have the money now to send my turbo to BNR for upgrade. Not sure stage one or two. Done a bunch of searching and not finding my plan in anyone build.
My build is a S5 irons and housings (stock ports) with S4 N/A rotors and 4x 680 injectors. FMIC and 3inch exhaust, no emissions. Haltech PS1000. Was thinking 10 psi max for a goal between 250 and 300hp. I want the engine bay to look as if Mazda had built it, so I like the stage one for that.
