The R31 never got the RB30ET - it was only in the Holden VL Commodore (and Calais) - and they're starting to be worth a fair bit of coin these days.
Another good swap might be the Toyota/Lexus 1UZ-FE 4.0L quad cam V8. Plenty of people have done that swap and they're tough motors. Space is a bit tight 'cause of the x2 DOHC heads but people fit 'em in and there are mounting kits out there too (www.rodshop.com.au has a pretty comprehensive one). There is a guy from NZ on here with a 1UZ E30 - sounds tough and goes really well. Just needs big cams and a supercharger for more fun!
