R33 Engine Pull Advice

[Blipman]

I'll be doing an engine swap in my R33 GTS25t soon, I have an RB30 bottom end/RB25 head combo to fit in. The new engine doesn't have accessories, clutch, flywheel or injectos so I have to swap all of these parts over. What wearable items (e.g. injector o-rings) should I be replacing while doing this either because they are likely damaged in the swap or because it's good preventative maintenance practice? Any mods or checks that are easily done while the engine's out that aren't while it's in? And aside from flywheel bolt torque specs that I've seen in the DIY section, are there any other bolt torques that it's critical I get right? Finally I plan to lift the engine and gearbox attached out of the top of the engine bay, I assume it'll all fit.

Thanks in advance.
