Default Bigger injectors installation

Hello everyone, I have installed a turbo on my Honda Accord CC1 with F20A7 engine. I had to change the injectors so the flow is high enough and thus bought EV14 Deatschwerk 550cc (17U-01-0550-4) but they are not designed specially for our engines.
To install them, I have to remove the resistor box, and change the clips from USCAR to an OBD1 style. Am I right?
Do I have anything more to do so they are fitting/functioning? Maybe tophats?
Thanks!
Worgche

Hey,

the B/H/D family is usually a 14mm bottom with a 10mm top ( fuel rail ) . The injectors you got are 14mm bottom with 14mm top, you will need to buy an adapter as you noted, then play with the spacers on the fuel rail to have it fit correctly . Then lastly is the connector, you can buy the EV14 adapter to obd1, or depin and rewire your current injector connectors to the EV14 style.


Here you can see ( its the same injector body style to the ones you got ) .

Thanks for all that info ! I got a F serie engine (F20A7), are the top/bottom sizes the same as B/D/H ?
So for the things I got to buy, a 14 to 10mm top hat adapter + a connector adapter from USCAR to EV14 are enough if I understand correctly

Edit: is this kind OK ? https://www.ebay.com/itm/145172791609

Yes, that should do it .

I dont have personally experience with the F20A7 , but it's the same for the F20b. So you should be on the right path .
