What size injectors should I buy? I have a D15 that I am going to be switching to V-Teck and after I am done I am guessing should be making around 150-170 HP. After I install them will I have to reprogram the ECM?

 

hi,im doing the same thing,you can use your factory injecters or the ones from the vtec head your better off with the vtec intake and injecters better flow, the ecu you need is a p28 get it for auto or 5 speed your choice,youll find what you need in the threads by FINALIMPACT his the man that inspired me to go for this look for honda mini-me conversion by FINALIMPACT his the man, thanks.let us know how it worked out.

 

the d15 and d16 "vtec" injectors are both the same size, so there is no need to swap out for bigger injectors unless you are also going turbocharged or supercharged, etc

 

Well every thing else is going to be new I would hate to use my old ugly injectors right now I have DC header, cold air intake and I have an OBX intake manifold, MSD external coil kit, high flow cat and MUGIN fuel rail coming from E-BAY I am going to be modding the **** out of the motor and plan on getting a comp street strip cam that will move my shifts to around 7,500 RPM my stock injectors are going to handle this?
