Patrol God
I am not rapt with the lighter gearbox bolted to the RB30. Yes they had a higher first gear, as its guts is designed for skylines. When I was seeking info about rebuilding the first gearbox that let go, a supplier confirmed that it had the same ratios that Commodores ran.
My advice is: not to follow my advice.

Compared to the gearing used for a TB42, 1st gear behind the RB30 is very tall and engine braking is minimal, even in low range.
I have tried to descend some very steep, but short tracks locally, by using different methods.
Using just the engine, it revs to about 2500-3000 RPM before there is any noticeable braking effect.
Of course, by that time the speed is suicidal and I have had to apply the brakes so as not to smash into the bottom of the hill or bounce off the track.
I have also found that applying the hand brake when moving, even very slowly is not an option as it tries to grab and shudder violently.
I guess there's an issue with the hand brake shoes/drum to give out a shudder like that.
I've done steep downhill engine braking on first gear, but can't remember I compensated with brake or not.
I'll have to try again.
