My swap is straight piped, and you can hear the turbo plenty well enough once it spools. Don't expect just-off-idle turbo noise like a PSD though, stock 617's just don't spool that soon.

You can hear it a bit in this video.
Also, my swap used a redrilled Toyota flywheel, I have no issues. I would expect your Ranger flywheel to work just fine, weight wise. Be aware that you'll have to have it balance matched to your existing flywheel.
