Hmmm, logic would suggest that stock turbos would not benefit significantly from the improved intakes, for starters the OEM inlet snouts are properly sized for the TD03 compressor wheel exducer, where as on Stage 2 turbos such as those from RB or VTT they are not. The Stage 2 turbos also move a lot more air than the stockers.

Having said that no one would have thought the TFT kit would realise such substantial gains on RB's either, so...

I'm pretty sure some stock turbo guys in the US would have bought this kit so we should know the answer to that soon enough.

As for pump gas gains on RB's, yes I would have to think so as the improved compressor efficiency should allow for an increase in the power ceiling relative to a fixed octane, before the onset of knock etc.
