Yup the spoolin post was against all the evidence and other posts.and the thread you mentioned,the guy also using RDX injectors,which are being used for K20,k24 ,R18,RSX. so thats why i got confused.but now i am clear.Thanks to you.can you people tell size of our top O-ring, 11 or 14 mm?
Meanwhile the TRE responded to my email.he said to send me a pic of my Injector.


Good thing you asked and good that it's all cleared up. :nod:

Spoolin could reply that it wasn't a 'direct' fit without slight modification though.

I will have to measure the top to see which it is.

But i have decided.i will order those RDX 410 cc when my tuner decides what Tune we will be using.i will take pics and may video it for sake of others who are confused.i will list any problems we got during install.

Just ordered RDX 410 cc injectors and AEM F/IC. Lets see when they arrive

why not wait for ktuner to release their flashing system?

since you did order the aem are you going to order a boomslang harness or wire it yourself?

Mine one is a complex matter.it has body of Ge8 but engine of CRZ.i asked flashpro if i can use their JDM CRZ CVT flashpro because that is what mine has,but they said,it doest matter if engine are same.the ECU's will be different. i know they are being on defensive side.
similarly i asked ktuner,but he answered that your model not supported at this time.
So i am better off with universal tuning products.
i have hired a tuner online.he will do online live tuning with fee of 250$
he recommended AEM.so i ordered. i am not using harness becuase mine is a mixture of Ge8 & CRZ.so wiring will be done by a local motorsports shop which will also install the kit.

the stock injectors use a 14mm top o ring.

ah I see the difficulty with your setup.

Why use the crz engine rather than the ge8?

I have had some serious thoughts about using the ge8 engine and swapping the ignitor ring and the cam sensor so that a gd3 ecu will work with the engine. That way I could have a 3 lobe intake rather than the 1-2 intake valve vtec setup now.

Ha ha it not my choice to use CRZ engine.ITs OEM from Honda Japan.The Fit Hybrid RS version there have same drivetrain as CRZ.i have ordered injectors anyway.we will see how they fit

Atlast completed my turbo project.and i used RDX 410 cc injectors,and those are direct fit,no alterations to fuel rail.the OEM wiring harness dont fit on them,so i had to use wiring clamps which came with my ordered injectors and tap them into factory injector wirring harness,that is just 2 wires per injectos.that was pretty easy

Can you please tell me if the yellow wire with black stripe on all 4 injectors is positive or neg? Forgot to make note before I depinned them. TIA!
