I wind my 2.4L LR up to 8000-8500 and it just seems to love it. Marco (Magnus Motorsports) told me once about a guy that bought one of his long rod 2.4L engines spinning it up to 10,000+ rpm in Australia with no problems, but that might be where longevity could be an issue.

Of course rpm has some to do with the motor going if you are reving the shit out of it all the time but I think running really high boost has more to do with it. In Steves case if he keeps it around 30-33psi give or take it should be fine with a good tune. The failures you read about are usually people that are in the 35psi-40+psi range.
Its seems like half the DSMs you read about in the high 9s and low 10s are running that 3575.
