okay i have a 95 JDM H22, and i want to get some new injectors. a friend of mine said to use a set of OBDII one's and just make sure i don't hook up the injector restor box. is this true? or should a get a set RC or something.
BTW the injectors would be for N/A up to 300hp thanks

 

stick with the same that will match the ecu you're gonna be running. if you're running a obd1 ecu then use the corresponding ecu don't jump gens....

 

oaky, i have a JDM P13 now OBDI. so the OBDII injectors don't "flow" better.
I was told they do thats why i ask.
and...... soon i will be using a P28 rechiped for hondata. does anyone know if i will need an resetor box for that rechiped ECU????

 

Okay first of all. ODB I Prelude injectors are like 320cc while ODB II injectors are saturated and 290cc. So dont be fooled in thinking the ODB II ones flow more. If you still think you need to upgrade your injectors then just get some DSM ones or pay more for a set of RC's. And yes if they are of the peak/hold variety then you still have to get resistors/box in order for them to work properly..

 

If it's a '95 motor and ECU that you're using (OBD1) than you already have a resistor box.....in addition, the JDM injectors flow even more than the USDM ones, so your current injectors are probably around 350cc....
Spend the money where you're really going to need it: the motor.....if you're planning on 300 whp N/A on an H22, it's going to cost you a LOT of money.....the injectors will be fine if you up the fuel pressure to 50 psi or so......

thanks for all the help
