Hi all,

As above, looking for a standard fuel rail and injectors for a H23 engine.

Thanks

Steve

H23 Fuel Rail and Injectors

It would help if we knew the car/ECU/wiring you plan to use this on. Since you are in search for H23 parts, I suspect it is 4th gen Prelude. In that case your cheapest option is using f20 rail and 240 cc injectors. H22 rail will also fit, but fuel pressure regulator might be different, I will get back at you about that.
Beware of impedance on injectors. If they are low-impedance then you don't need anything else. If they are high-impedance then you will have to replace you injector connectors and remove your resistor box. Injectors can also be acquired from B and D series engines equipped with VTEC, as all of them have the same 240cc injectors.

Thanks for the reply!

Sorry, Yes I have a 4th gen prelude, it has a stock ecu and wiring.

Ok, I will have a search for those parts.

Really appreciate the help!

Steve
