Bigger Injectors in Stock D16?
I'm slowly putting together an engine and turbo build for my EK. I'm building a D16Y8 currently, and I plan on putting it in mostly stock and then running it as is until I gather up all of my turbo parts to put on at a later date.
My question is, can I put my 440 cc injectors in now as long as I use my chipped computer, and just run a stock D16Y8 map with Crome and input that I have the larger injectors? I'd rather put this engine fully together instead of pulling out injectors and spilling gas and stuff all over when I go turbo.

Re: Bigger Injectors in Stock D16?
if you're not putting the rest of your gear on until later, there is no advantage to a larger injector....
running bigger injectors on a stock engine is pretty much pointless...

OK, thanks, I'll go with the stocks to avoid any issues. And to the previous poster, I'm not expecting any gains from using the larger injectors, I just wanted to put them in beforehand to save a little effort and mess later when I put my whole setup in.

Re: Bigger Injectors in Stock D16?
whats the easiest way to add bigger injectors? looking into everything for a turbo setup. what setup are you going to be using as far as ecu, injectors, any other specifics aside from the mechanical aspects of the turbo.

Can I run 370cc injectors on the stock d16y8 vtec motor internals? I am upgrading to walbro 255, pressure reg kit, Cai, full flow catback with 4-2-1 header, race timing, aem wideband, msd blaster 2 coil and distributor kit, ngk v power plugs. what afr should I look for when tuning with this setup? And what should the fuel pressure be set at for a first fire? And I plan to turbo later with a turbo cam, internals, valve train.

You cannot run 370's with a stock ECU. You will need a way to modify the tune for the larger fuel injectors. Fuel pressure should be about 45 psi with the engine idling... NO vacuum connected to the regulator. You will NOT need larger fuel injectors until you add the turbo kit... even if you did the engine internals that you have listed and kept it NA right now. The stock injectors are large enough without the turbo kit.

Re: Bigger Injectors in Stock D16?
Can I run 370cc injectors on the stock d16y8 vtec motor internals? You can use larger injectors on a stock internal engine, but you can’t just plug in larger injectors while using a stock ECU (computer) because it will dump excessive amounts of fuel into your engine, causing it to bog down at the least, but not work at all more than likely. I am upgrading to walbro 255, pressure reg kit, Cai, full flow catback with 4-2-1 header, race timing, aem wideband, msd blaster 2 coil and distributor kit, ngk v power plugs. Those are good parts if going Naturally Aspirated however you’ll probably want a different exhaust when going turbo. You can’t use the CAI or 4-2-1 header once turbo, so you might as well not install those or purchase them if you haven’t already (or look to sell them and put the $ towards turbo parts). what afr should I look for when tuning with this setup? What do you plan on tuning with, just the fuel pressure regulator? If so you can add a few psi of fuel pressure to compensate for the header, intake, etc. if you insist on installing those parts, but the gain will be minimal and you’re better off planning for your eventual goal of turbocharging. And what should the fuel pressure be set at for a first fire? What Dax and JRCivic1 put, or a few more psi since you’ll have a CAI and exhaust/header if you go that route. And I plan to turbo later with a turbo cam, internals, valve train. That’s good, but just be ready to spend at least a few thousand to do it the right way if you plan on a cam (few hundred $), internals (pistons,rods,etc. 700$ plus), valve train ($600 plus), and the turbo kit ($2k plus) for quality components.

There is really no reason to install them now. It is such an easy job to install the injectors when doing the rest of the turbo. Might as well install the turbo and tune everything at the same time in my opinion. Actually, when I did my turbo, I even left the stock injectors in, drove the car to the dyno with the wastegate open to avoid building any boost, and just quickly swapped the injectors over when we were putting in the new chip for the tune. Quick and easy.

This is a 13 year old thread with a completely different subject that you've randomly bumped with a one-liner question and no other details.
Also yes Go-Autoworks is literally the last company left that makes off-the-shelf full kits for our cars that are actually worth buying.

No problem man, good luck with your build. Make a new topic with more info about what your goals are, budget, etc if you need more help.

Which kit you buy will depend on your power goals, how the car will be used, and your budget.
