Ya i just bought a 89 crx and it has a fuel pressure regulator on it and i dont know the manufacture i think its a B&M but im not shure and i dont know how to adjust it can you guys give me any tips?

 

Why do you need to adjust it ?

 

if it's a b&m it will have a nice top half and oem bottom half.
To adjust disconnect the vacuum hose from the im, loosen the nut on the fpr, turn cw to raise pressure, ccw to lower. Put the vacuum hose back on.

what motor and mods do you have?

 

yeah its my friends he bought it for $900
here is the mod list

and maby more we havent taken apart the engine to check for cams pistons etc

you dont realy even hear it kick V-Tec so we are not shure if the guy wired the v-tec right. He is thinking about a ls swap into it but inst shure yet.

 

Oh and he also wants to know if a B series transmisson would bolt up to the current D series block.
He thanks you guys for the help.

No. Any D can bolt up to a D, if its hydro its gonna need special mounts to go in the Ef.

get the correct ecu for the vtec to work correctly. the SI ecu isnt a vtec ecu.

So back to my question, why are you messing with the fuel pressure ?

More fuel = more powwwer!

 

The SI ECU is a B series ecu

 

if its a 88-91 si ecu, its a D....

 

its a 96 si ecu cause its hiting v-tec just cant hear the diff. when it kicks it kicks at like 4500 rpms or something close to that+

 

Theres no such thing as a 96 si? Maybe an ex?

 

and 96 is obd2...
