Congrats, how many miles on the 2.4?
Longevity of the 2.4 is the only thing that really worries me.
Can't wait to see what your final numbers/powercurve looks like.

I have yet to see any real evidence that the 2.4L has longevity problems. Keep an honest rpm limit of 8500 and it should last as long as any 2.0L at 9000-10,000 rpm. 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.

About 1500 miles. The other 2.4 I built at the same time has around 10K miles at a similar power level and gets flogged on the streets of Duluth regularly. They seem to hold up fine.
