im on to purchasing a set of injectors, now without the motor not even built yet, how do i go about seleting a size.

i was thinking maybe 1000cc, is what ive been hearing.

its a fully built b18b with b16a3 head. turbo t3/t4 for now and 9:1 pistons

thanks guys

What's your power goal? That will help you determine your injector size.
More power = more fuel = bigger injectors.

i do want to get gt37 but this year im using turbonectics t3/t4. soo 600hp would be nice for next year, maybe 400 with this turbo setup

D.T.P

You should be fine with 750cc injectors for 400+ whp setup. Though I believe for your ultimate 600whp goal, it may be pushing it.

You can calculate the size I believe by calculating combustion chamber volume, air/fuel mixture and air entering the engine. I remember seeing the formula somewhere, ill get back to you for that.

Rc site can help you calculate.

i used the calculator for 450 crank hp. and it says to use 955 injectors soo basically 1000cc. might as well get them, can always adjusted during the tune. sooo im going to get PL4-1000H. correct? it says honda syle soo asuming those are good

D.T.P

for 450hp you will need 886CC injectors.
Did you use 0.50 or 0.60 for B.S.F.C
Either way, 1000cc injectors will be good. Though i would say double check with Zeeman.

i used the 0.60

D.T.P

I did it 2x and got 885.9CC
Either way, should be safe with 1000CC injectors.

Better to get the bigger squirters now and be prepaired for future mods.

you say to go bigger, well i could get 1200s. now peak&hold will be good rite? there is no saturated ove 750cc

MPR

Well, you don't want to go ridiculously big, but big enough to efficiently supply the required amount fuel, with some room to grow.

if you're going to use 1000cc's in a honda, get the Injector Dynamics 1000cc's. They're linerally scaleable up to 1600cc's depending on your fuel pressure.

They're a saturated injector and won't require a resistor box. They idle unlike any 1000cc injector out there. Yes, they're expensive, but worth every penny.

just to confirm the rite ones, when ordering, they are product code: id1000, and they other 1000s are peak n hold soo im assuming these are the guys for 115 a piece
