support 12psi? There is a lot more then 12psi of pressure inside the cylinders.
If your talking about 12psi of boost, that could be anywhere from 100hp to 350 hp so thats not any use...
How about you let us know what motor you have, your set-up (I assume it's turbo) and how much power you plan to make. Unless you have high static compression and a giant turbo, most stock honda's can handle 12psi with the right tuning. I've said this several times before, but i'll say it again...(search and you'll find this info)..
Psi is nothing more then resistance (pounds per square inch). You can cram 2psi in your motor and blow it, or you can cram 15psi and have it live a long life. It's all in the tune and the amout of power being produced.
Exceeding the power limits of the motor and crappy tuning blow motors, not resistance (psi).
Generally d-series can handle about 220whp in stock form and B-series can handle about 300whp safely....in stock form.....

*disclaimer****
When I say stock form, I mean stock internals,(rods, pistons,etc). Not a stock N/A honda engine. The motor without the turbo would be considered stock, add the turbo to the motor (while still internally stock) and it can handle about that much power (listed above) ....had to add that for anybody that doesn't understand when I speak the words "stock" and 300whp in the same sentence.
