One of these numbers is extremely difficult for me to believe. Guess which one?

automatic transmissions are a little more sensitive to horsepower upgrades than manual. id say if your actually going to try and make that much and put it through an auto trans. i wouldnt go to far over 300 and you torque converter might not like much more torque than the factory motor had. just be cautious with how much power your trying to put through the trans and listen to it. dont go crazy and blow it up.

Yup. That's why Honda de-tuned the engine in the NSX so that it makes only 252 horsepower in the automatic transmission versions (which comprise about 9 percent of NSXs), vs 270-290 for the manual tranny cars - they were worried that the automatic couldn't reliably handle the higher horsepower.
And if the automatic in the NSX couldn't handle it, I wouldn't expect the one in the Prelude to do so.

Eliminate the accumulators (or stiffen them significantly), get some good frictions, and up the line pressure, there are some kits out there for this. Get a good external cooler too. They can hold more power than people think. The preludes have 4 frictions per gear, put 100-180psi behind that piston and that gear is not going anywhere, especially when the accumulators are eliminated/disabled.
What is the redline on the auto NSX vs manual, and is the torque the same? Given the displacement is the same torque should be too, RPM does not matter in this case. Torque is the true measure of an engines output, RPM is just a figure to tell you torque/rpm relationships IE "horsepower". Most auto's have a lower redline and thus less HP but similar torque.
