It can be tricky at times with engine editor to tweak engines to exact figure, just a couple hints:
If you want a torque monster you want the torque spread to be at a lower number and also the cam timing at a lower number this is what gets you either closer torque to HP or more torque than Horse power like a Diesel
Engines Inertia will adjust how easily the engine revs up, so light engine rotational mass, think of this as a light weight or heavy weight fly wheel. Most modern street cars would be from 1.0-1.3 diesels over 1.4, Formula engines 0.6-0.7 and regular race engines most of the time around 0.7-0.9.
You building an old 1920s-1960 you probably want to use somewhere around 1.4-1.6.
Turbo multiplier is how quick the turbo spools, diesel trucks I found the sweet spot right around 0.50, street stock turbo around 0.40 and race cars probably around 0.30 give or take just try it out until you feel or hear the difference. You can also hear how fast the turbo spools
