For $700 or so the tomei poncams 260 deg 9.15mm lift (had these in my 32R with 2530's) go well if you are after 330-400WKW, mainly allow you to run less boost for the same kw output as stock cams and increase torque.
There are also others like, jun, HKS 264's, but check out the RB26 dyno results to see what others are getting out of their setups.
