if you were going to do this you'd need to go all out.
forged high comp pistons, lighter rods, balanced bottom end with around 11.5:1 Comp ratio, some nice meaty cams, maybe 288's or something around that with a shortish duriation but high lift. basically want to make the bottom end hold together and swing to around 10,000 rpm.
defo use a plate and use the RB26 ITB's, make some nice and long intake trumpets, big air box feeding air direct to all of them.
and then put it in something light...
