i have a h22a jdm with type s cams intake exhaust crank pulley and ecu what is a good recommend fuel pressure for theses mods?

 

what ever gives you max power on a dyno, and is not too lean is the best. The only way to tell what that is for your can is for you to hit a dyno and tune your car.

 

if you ecu is not tuneable then yes the best would be to dyno it, and adjust your fuel pres, you don't want to go too lean, and using just a fuel presure adjustment isn't going to be the best think to tune,

if you looking for a good place to start with your fuel presure start around 42 - 43 thats stock.

 

how abou setting it at like 55-60 at wide open throttle

 

I bet you will lose power if you do that. The prelude runs rich as hell at WOT, unless your running boost. Making it more rich will just make the power go down more. Just leave it at stock pressure, untill you can get on a dyno with a wide band O2 sensor.

 

what is stock on type s cams

 

there is no such thing as "stock on type-s cams"
as far as i know all obd2 h22a's run igher pressuer htan obd1.

your best bet is to run 42-43 psi which is stock for the engine,ecu etc...and then get on teh dyno.
