Im working on upgrading the intake and fuel system in my CRX sins im putting a bigger intake manifold and a cold air intake on im going to need bigger injectors the prob. is im not sher what the stock injector size is I think its 250cc or 255cc ??? and I need to know what a 10-50cc diff. would make ???

stocks are 245's and bigger injectors r not going to make n e diff in that motor. stock injectors r going to be good to around 200hp at 80% duty cycle B18c still use 245's, unless your looking for boost or spray i wouldnt waste the money, combustion chamber and CR r going to be the same, your not going to burn anymore fuel

Ok cool thanks for the info why I ask is becuse iv put cold air & ram air on a few cars and gain power at high RPMs but at low RPM when I need it I get a real lean burn and lose a lot of low end TQ now when it comes to tuning/hot rodding the rules have always been if you add more air you must also add more fuel now if my stock injectors are rated for 200hp what would be the best way to up thare flow for a more even mix

Bigger Injectors, Fuel Rail, or a Fuel Pressure Regulator ???

and for that matter whats the stock fuel pressure ???
