Ok heres the situation......
1996 integra gsr car
1995 jdm h22a engine
1995 p72 ecu

I have a header, intake, clutch, step colder plugs, aem fpr, and zex nitrous kit.

Currently we are running a 55 shot but we are interested in stepping it to a 75. What timing and fuel pressure are some of you running?

Zex reccomends
Zex kit 55hp 65hp 75hp
nitrous jet 32 35 38
fuel jet 36 34 32
Ignition retard 0* 2* 4*

Is that what some of you are running? We also are using the stock ignition with internal coil due to the jdm distributor.
any responce is appreciated(sp?) and thanks for the bandwith.

Just go with what zex recommends fuel pressure should be set to stock because that is what the jets are calibrated for.

 

Run what is recommended and check the plugs after a run just as Zex recommends as well, then change jets accordingly or don't depending on what the plugs tell you.
