You can't say that an increase in peak torque has any negative effects just by the fact that it is at a higher RPM. Does the motor actually make less torque at 5200 than the old motor?
You quote a torque peak of the Prelude Type-S, by the way, which comes with the dual stage intake manifold. The Accord Euro-R is quoted at 6700 for peak torque.
If you want something with a low torque peak that will keep running longer than you are alive, perhaps you should look into a SOHC Prelude, which will make peak torque at 4500 RPM. It will also be very slow, because the unfortunate thing about engines is, the faster they can be spun (and still produce power), the faster they will make a car go. Formula 1 engines are in so many ways utterly conventional...no exotic variable valve timing, turbos, variable geometry intakes, run on gasoline...but they make over 700HP out of 2.4 liters of displacement....caused by RPM.
Heck, a regular H22 (6800RPM power peak), if maximum acceleration is desired, should be shifted at fuel cut off in the first three gears. Just like an H22 Type S or H22 Euro R.
If you want something that is going to last longer but also go quickly, maybe you should get a bigger engine or something with a turbo.
