Sydneykid,
What power do you think that the GCG Stage 1 & 2 would make (approx) on an RB20 with Wolf 3d v4, GTR Injectors, Bosch910, Exaust & Dump, Hyperflow Cooler & POD at around 18-20psi.
I am considering getting a GCG High Flow opposed to my GT28 because there is less fabrication and I will be able to do the work myself.
GCG quoted me $1550 for a Stage 1 @ trade price which is damn good I thought.
