It sounds like a really fast car. As far as lowering to 18psi, that will not hurt anything. You will notice a power loss, but the engine, turbo. Will last a lot longer, and things won't break as often. I actually think it is a good idea. I assume when the engine was rebuilt, they redid the lower end with performance parts; otherwise, I feel it would have already come apart.
