I'm about to do a B16a swap into my 94 EJ1. For the B16, just finished putting in JE piston's with 9.0 to 1 comp., Eagle H-Rods, and a KMS block guard. So it's safe to say it can handle at the very least 15 lbs. of boost.
I'm going to do a complete turbo set-up with a T3-T04E turbo, and have it peak at about 12 lbs. Being run with a Hondata ecu. I plan to just upgrade the stock injectors to supplement the boost.
My question is, what fuel injector size would be recommended for this set-up? My options are 440cc, 525cc, or 650cc. Is 440cc enough, better to go 525cc?

I'm definitely not an expert, but I'd say go 525cc if you plan on upping the boost down the road. What is your HP goal?
Hopefully someone with more knowledge on this will chime in and tell me I'm right

At this point, I don't have any hp goals. I just know that a boosted b16 built correctly will be at least 150 % better than the currently installed single cam that leaks more oil than just pouring the stuff out of a bottle.

update: just spoke with a Hondata dealer here that does a lot of turbo installs in honda's. nissan's, every thing. He said that for this application he highly recommends running 750cc injectors. So that's what I'm going to do. Hey, better to have too much than not enough right?

I have always heard you can have to much of a good thing and that you need a carefull balance of air to fuel mix.
If your injectors are to big they will put to much fuel into the engine and cause it to flud, I might be wrong so someone please correct me if I am.

With the Hondata ECU ( and other control systems), the computer will control the actual amount of fuel going to each cylinder, no matter how big of an injector.
