how much pouds of presure i can place win standard injectors and standard fuel pump and how mani check valves i need install in the map sensor

 

come again?

 

Factory fuel system by itself can handle about 2.5 psi at the most I'd say, probably a little less. It wasn't designed for readings above atomospheric pressure.
However, the fuel system can be slightly modified w/ a new pump, FMU, adjustable regulators, etc, etc.

The MAP sensor can read up to 10.5 psi(http://www.hondata.com resource) before it will throw a check engine light. You would need to install check valves to prevent the MAP sensor from reading above that amount of boost. Or just upgrade the MAP sensor instead of having wires all over the place

 

I know you meant to say it can register 10.5psi before its out of its operating range. Unmodified, it will throw a CEL right after the boost threshold.

I took me 3 checkvalves to keep the MAP happy at 6-7psi.
