The OM606 is a completely different beast.
It's not the engine that has a problem with 6000rpms, it's the injection pumps, they just won't deliver the fuel up there... The inline pump on the OM606 is what makes them able to rev... But they're a frikkin' nightmare to setup and very finnicky...
The 25tds is a GOOD engine I'd say, it's prime for mucho boost... Bet you the bottom end will take some serious abuse, not as much as a 603 or a 606, but they're something else!
The 330D engine isn't that good to begin with, it's riddled with faults like the swirl flaps, the turbo is nigh on it's limit, you'll sturggle with nozzles and HP pumps, and then you've got to pay for remapping... Which no one really does that well tbh, it's pretty much a 6cyl HDi tbh, has all the same problems of lack of parts and knowledge equalling muchous £££ to find the people who do it properly and are usually up tight and dont let any info out about them.
