Hi guys, I'm currently building a fairly basic B18B-B16A2 hybrid. I'm wondering if stock injectors and pumps are fine to use.

I have PR3 pistons that I think will give me 11.3:1 CR, just hoping to match the B18C2 HP numbers so not much to chase.

 

Stock 240cc fuel injectors will work just fine... the fuel pump may be an issue depending on what chassis you are putting this swap into. A Civic CX or VX will need a bigger pump... Integras will have a pump that should work just fine.
