hey guys im a noob at tunning hondas just wondering im doing an all motor build with my b18c1 block with a b16b head

im using nippong racing p73 piston 81.5
with ctr cams
skunk2 intake
jvt headers


what im wondering what size of injectors should i use as of right now i have some denso 280cc injectors someone told me that i need to be using some 400cc injectors... and what kind of gas should i be using some 93? maybe well thanks a bunch

 

whatever your tuner/engine builder/dyno tells you you need is what I'd go with.

 

is it better if i use a vafc2 or a hondata s200

 

I'll put it to you like this... That's the same as asking, "is it better to use a calculator or a computer?". Apples and oranges. Your tuner/engine builder will be able to guide you.

 

lol i know what your saying but can i get an advice maybe cause im the one doing the building

 

will it be streetable use

 

go with hondata, From experience never go with a vafc they suck. I have s300 it works amazing plus you can use your own computer to do diagnositic like ses lights and adjust everything on your own if need be.

 

finallyy something helpful

S300 with a 2 step...even better

 

what kinda of gas are you running in this build that has a lot to do with inj size!!!

 

what the tuner wants to use is the proper answer. however, stock injectors should be fine at higher pressure. your cams are a little small for 12:1 compression but i don't see larger injectors being needed on an engine that is going to produce that power level. if you have 280s@45psi {guessing} that's a little larger than stock and would help keep the duty cycle down. normally you don't need to step up injector size unless you start running near 100% duty cycle.

 

dude you are awesome thank you very much dropping in the engine on friday hehehehe cant wait

 

no , u should get bigger than stock injectors, so you can run them at lower duty cycle, and you won't have to worry about them maxing out then ur motor running lean, as for ecu hondata s300 its so easy to work with, well worth the money!
