brzys/bengines — reverse-engineered prompt

Build me an MTA:SA 1.5 resource that replaces the default vehicle engine audio with custom sounds and makes vehicles feel much more alive on a multiplayer server. It should automatically choose the best engine sound for each vehicle based on its handling or class, with a solid range for buses, bikes, sports cars, trucks, boats, planes, muscle cars, and normal street cars, using the included sound packs. I also want turbo effects with a nice whistle and blow off sound, plus ALS style exhaust flame effects.

Please keep it smooth and reliable enough for a busy server, and make it easy to customize later if I want to add more sound packs or tweak how vehicles are categorized. I’d also like simple functions to get a vehicle’s current RPM and gear, and a way to turn the custom engines on or off so the original GTA sounds can be restored when needed. If anything is unclear, look up the current MTA docs online and wire it up cleanly.
