Diesel engine swaps

So a couple things that come to mind here.

You can hear a V8 in a performance street car. Are we looking for a quiet engine that makes big power? I can say my 24V's are quieter than my 440 with full exhaust.

The early Mercedes were hot boxed (no intercooler). There are places with them to make more power besides simply adding boost pressure. Fuel, larger turbo, intercooler, exhaust, intake, timing are some of those. (HX40 chargers, intercooler, replace head bolts with studs and 8mm fuel components)

This would be for a C-body cruiser not a performance build. If I kept it gas I'd put quiet mufflers on it. I have my Duster for going fast and making racy V8 noises. And yeah diesel noises are completely different than loud gas engine noises, and all you need to quiet down a loud gas engine is mufflers. Diesels make noise from the engine itself.

I know the Mercedes can be built up but one thing that turns me off is that most internal engine components are INSANELY expensive. Like a set of stock replacement pistons for an OM617 are around $1500... I know those engines run forever for the most part but if I'm going to crank it up to 250-300 HP I don't want to be screwed if something does break. The 4BT is attractive because it's super plentiful, and not European lol.

I'm still considering both options though.
