Don't trust the shit in Zoom, we have seen great results with Greddy intakes on RB 25-26 and SRs.
Pauls GTS is the highest power ever on my dyno with a factory Turbo at 300rwhp and 411 with a GT30 turbo at low boost,then theirs Ants GTR and SR that are basicly the best of their kind in WA. Shut up DP.
