Yes we do read it still
Cheapest option - do what RIPS does (as far as i know), buy a rb30e short motor, new rings and bearings. Buy a rb25de head, polish combustion chambers, away u go. when it blows costs less than 2g for complete motor
As far as vvt goes - im not using it cos its not in the 32, and thank god cos it sounds a hassle.
Normal rb25 oil pump will do.
Std. pistons will cope to 250rwkw if tuning is good.
HKS GT30 series is ideal for this engine. I will be running mine on for a month or so on the std rb20 turb that has been high flowed b4.
Or u could go out and spend the 10K + that it costs to do the perfomance upgrade side of it.
