i was wondering if anyone knows how many cc's the injectors off of a gsr, an itr, a h22 and a h23 are all from obd1 years. any info would help

 

All obd 1/2 B series are 240cc's saturated

All obd 1/2 D series are 240cc's saturated

1992-96 Prelude non-vtec (h23) Peak and hold 240cc
1992-96 Prelude VTEC (h22) Peak and hold 345cc
1997-up Prelude VTEC (h22 obd2) Saturated 280cc

 

thank you very much dubcac

 

Does JDM B16A 1st generation same type and size as B20B (97/98 CR-V)? Thanks.

 

They are different obd versions, however the flowrate and type is the same.

 

Thanks. Just some more questions, does pulse is also the same (I know the ECU control the pulse). I meant I have B16a head with B20B block.I know B20B needs more fuel,so if I set the fuel pressure regulator the same as stock B20B engine is it okay (around 38-45psi with vaccum off)? Also,the fuel pump rate is the same between B16A1 comapre to B20B? Thanks.

 

The fuel pump rate is determined by the pump in the car, not the motor. As for the FPR, you may want to bump it up a few PSI at idle, but I'd get a VAFC and have the fuel adjusted on a dyno to be safe.

 

whats the difference between saturated and peak and hold.

 

Saturated = high impedence
peak hold = low impedence
