What size injectors?
 

I want to know what size injectors to get for my setup i plan to run 10-17PSI when its done and setup. I have the following:
Fully built JDM Accord B20A Wiseco 8.5:1 Comp
Garrett T3 Super 60
Spearco FMIC
MSD SCI Ignition
Im looking into using AEM EMS possibly

I want to use RC Injectors but my problem is i need Peak and Hold Injectors for my car and they only have the following:

320 cc / min
370 cc / min
500 cc / min
550 cc / min

I was thinking the 500cc but im not sure if i would be running rich if im running a lower boost? and i know the 370 are not gonna be big enough. Thanks I figured i would ask since you guys know your ---- and this is my first turbo project.

Re:What size injectors?
 

I'm not real familiar with the EMS, but you should be able to use the 550cc injectors or 500cc wihtout any problems. Why would it run rich? I'm pretty sure the EMS has an input for injector size so all you would have to do is enter the size and tune. You are correct about the 370cc, they would be too small.

To be honest i dont know much about sizing injectors and dont want to have to buy things twice. Iv been buying the best stuff possible to make this engine hold up and run well and be reliable on top of it. The only reason why im looking into AEM is because i can easily put it back to stock if needed because im not sure how its gonna work with emmisions when the time comes so this way if need be i could easily swap to my stock engine and be good for another 2 years. Plus the price is not bad and i have a local shop that uses it and is known to be a great shop.


Thanks for the help again Dr.Boost!

Considering your going to be running high bosst, I would go with the 550cc. You don't have to use all of the duty cycle. You're better off in this case to be too big, than too small as long as the EMS can input that large of an injector. I'm assuming it can, but I don't know for sure. You might want to talk to that shop and see what they would recommend since they will be doing the tune on it.

Thanks i will post some pictures of my setup later this week the manifold and downpipe are almost done getting coated. So far its coming out really nice but it hasnt been cheap either so i better be happy when its done but i think i will be and it was kind of overkill but i wasnt gonna run a low boost setup on a stock bottom end so i figured i might as well go the extra mile and do it proper. So far everything has been a challenge but has come through. I went as far as having ARP match studs up, rod bolts, and got exhaust studs aswell. And im having Cometic make a headgasket and working on finding an LSD but that is a tough one with my odd ball transmission.

Re:What size injectors?
 

Sounds good. That sounds like a really nice setup. Make sure you post some pics of that when it's done. It's always nice to see new setups, especialy when it's a different motor than the usual B16, B18, D16.

Keep us posted. :)
