… What??? Of course they’re amazing and free reving. If you want to look it up too, the Silvia RSX (Japan only) came with a CA18DET.  
Yes they are free reving. It’s the same bottom end. Of course it won’t be as free reving as the same engine with more power.  
S12s came with CA20E, and CA18ET in Japan as well as here. The US got a VG30E instead of the CA18ET in the last year or two of production of the S12.  
The CA18ET that was offered here is the exact same as the JDM ones and is just as free reving as those.
