I am building an LS/VTEC motor, with stage 1 Cams (skunk2), minor port and polished head, and civic type R pistons with a b17 head and skunk 2 manifold. I'm pretty sure that I have to upgrade the injectors because 240cc injectors I'm told will only support 48hp apiece. I am not going OBD1 because I have a PR3 ECU and a VTEC controller. Only problem is I don't know where to find "peak and Hold" OBD0 injectors (around 310cc). Can I just use OBD1 peak and hold injectors out of a first gen h22a (92-96 prelude)?

 

As long as the injectors are peak and hold they will work. You will however need to wire in the prelude injector clips.


For aftermarket injectors:

They should have what you are looking for and can probably answer more questions than we can.

 

Thanks.
