ok so i got a ls/vtec will my stock injector be ok or do i need bigger ones.

b18 block
12.1 comp
b16 ported head
buddyclub spec3 cams
itr manifold
exhuast header and all that good stuff.

 

your going to need bigger injectors with that setup i would recommend RDX injector witch are 410cc.The rdx setup should cost you less then what the RC injectors go for plus your gonna get that OEM quality.

 

im using around 270-280cc at 220whp on my lsvtec bloxC

prelude 310s or dsm 450 would be the cheapest route probably

 

I'm not sure about other tuning systems but I know Hondata doesn't like people running DSM injectors with their systems:

"DSM 450cc injectors will not work with the Honda ECU - the electrical characteristics of the injector are not suited to the ECU, resistor box or no resistor box.

If you use DSM 450cc injectors you will find the engine difficult to start, and the engine running lean at part thottle, plus tuning is very difficult."

i used dsm 450s with crome and neptune without any problems

 

I thought prelude injectors were 345 or 290 cc.

 

I figured I'd just throw it out there since we didn't know what tuning system he was using.

 

this is what i'm searching how to do. I want to use the RDX injectors on my N/A B16 but not sure what is needed on the IM or Rail to accept them.

 

hmmm...I thought the problem with DSM 450's was that the spray pattern wasn't the same as honda injectors? I could be wrong...

 

so yeah i used bre(bens rom editor) im a oldschool obd0 guy always was.. but yeah i used 450 with my old turbo set up and maxed them out but on lower bosst they always worked fine.... but anyway maybe ill just throw them in i also have 310 from a miata....idk with my setup which to use yet
