Sounds like someone's very passionate about their RB30.
Nobody said they didn't rev, just that they don't rev as high as an RB26. 8,000 rpm is nothing to be sneezed at and with all of that torque backing it up, it's a very good engine.
Take for example the world's quickest and fastest Nissan, the HKS 180SX that a few years ago made a 7.27-second 189-mph quarter-mile pass at Sendai Raceway in Japan. The 180SX is powered by an RB26 that produces approximately 1,300 hp at 9,000 rpm and 672 ft./lbs. of torque at 7,000 rpm.
I've also seen on some of my DVD's RB26's reaching 10,000 rpm.
An RB26 costs a lot of dollars, but compare it to an RB30 with a RB25e head and you've a lot of bang for your buck. The RB26 head is a lot more expensive and would take even more money to mate it up
The RB30 would be a better option for your money.
If funds were unlimited, I'd have a different opinion..............
