So basically the dpc doesnt reflect the engine itself. A safe boost is determined by original design. If the engine was designed for a turbo then its different than if someone adds a turbo to an n/a. It all depends on the engis who do the engine design. An engine design determines the mods it can take, yet if the engin has a big enought dispc then its ok to add a turbo, but how far it goes is what i am talking about.

So many people here know all about Turbos and how they work...its funny to see someone talk/type like they know something, but show them a compressor map and they think its a rifle target...
A stock motor honda will never, can never run 25 psi not even for 1 sec without blowing to particles. You need lower compression pistons, good forged rods, forged crank...whole lot of stuff to make that kind of boost possible. Only few stock motors are capable fo that kinda boost, such as TD, or Subarus (STI only), talons...ect ect...these are all cars that were designed for boost from the start. The other thing to keep in mind is that running 25 psi on one turbo can flow the same air as 15 on another. PSI means ....its all bout CFM.

the danger with that motor is that it starts off with such a high cr... the b18c5 was designed for road course racing, thats why it has the engineering behind it to hit 9000 rpm on a stock computer (let alone what you can do if it is remapped). I think the block comes 11.5:1 ... which means MAJOR work has to be done in order to bring it up to 25 psi.

Mr X, i am under another theory based on such and such, that this proves to be the right answer, can you research this and post another thread explaining that maybe there was a mistake in your explination.

you are pretty much correct...except the b series cranks are forged from the factory adn can handle any power that they will ever make
