I have a N/A 93 teg with the b18a1 and it is descently built with pretty much all the bolt ons, so i have proper air flow thru an expensive cold air and headers/ full exhaust, i have bigger plug wires w/ some nice ngk plugs and a hot coil, so now im going for the fuel system to match air to fuel to spark and i put a new fuel pump w/ BDL Industries rail and pressure regulator. I know ABSOLUTELY NOTHING about injectors for the DA's and was wondering what the OEM injectors flow is? And most importantly what brand and flow to go with my set up? Please tell me any particular preferations or experience.

Thanks a Bunch,
Justin

 

Intake, headers, exhaust, and plug wires are not what make up a "descent" build.

 

ok i wasnt being very specific, sorry my thread does not meet your specifications of perfection. if you want me to be more exact here you go ***got, besides what ive already said above i have a knife edged crank, itr rep pistons, shaved head to about 9 to 1 compression , full port and polish, full crower valve terrain, crower 404s and enough power to spank whateva you attempt to drive. yet im still running lean and need more fuel. so if you know nothing about injectors why even bother me with random crap like that. therefore my question stands, does anyone know what brand and flow injectors i should use in a b18a1 with a DESCENT build (meaning it's not completely bad*ss yet)

Thanks for nothing retard,

Justin

 

You are no help, kick rocks.

And for you Juicy! Look into getting some DSM injectors. You can find them for about $50-$75. The 440cc should be fine.

 

Minor bolt ons are fine, but make absolutely no case for a pressure regulator, replacement fuel rail, or oversized injectors.

Return all those items to stock. Getting a tune would be a much better use of money than those parts.

Just my $0.02 anyway.

 

ok thats alot of help and i appreciate both of yall's help but now im confused, one of you says get some 440cc's from DSM, and another says really they're not needed. three out of my four injectors are leaking right now anyways so my car isnt wanting to start because the plugs are drowning in fuel so i have to buy injectors regardless of power, is it worth it to go ahead and get some good aftermarkets or no???

thanks
justin

 

Since your stock injectors are not operating correctly, then the decision to buy aftermarket or replacement OEM comes down to a single question. Will the car be tuned? If so, go ahead and get aftermarket in whatever size your tuner recommends. If not, replace with OEM (size at least).

 

First and foremost Juicy...

When asking a question like this its wise to spill the beans on your "build"... So a full list of all your mods will benefit anyone trying to help you.

Second... when someone posts something that doesnt help... being an equal douchebag towards them doesnt help your cause.

Third... on you list of mods... you say you have ITR rep pistons and a shaved head resulting in 9:1 compression. You're either full of ****, completely stupid or have no idea what you're talking about. Also in regards to you build lowering compression will not help a cam like the 404's you claim to be running. Furthermore you have absolutely no need for any of the aftermarket fuel system parts you're using (fuel rail and regulator).

B18A1 compression is roughly 9.2:1... if you add ITR "rep" pistons it should theoretically bump you to 10:1 compression... (I used http://www.zealautowerks.com/bseries.html to calculate the compression)... and also lastly if you "shave the head" you raise compression you do not lower it.

So what I'm saying to you is... find replacement STOCK injectors and you should be fine. That's assuming your engine has just bolt ones. If it does infact have raised compression (ITR pistons and shaved head) and the 404's you're claiming to have then I would get RC 310's and have the car tuned by someone who knows a lot more about the topic than you.

 

Cpt xThread,

No im not a complete retard i swear, i was f*ckin with that f*aggot for no reason. your right tho i prob should not stoop tohis level. anyways the car is not that built no cams or shaved head but the rest is true, so i plan on getting an AFC of some sort to tune it all with so to answer your question it is going to be tuned. i was told that hp has a big deal with injector size and i dont know power but i would say around 200 judging by the cars i have raced and their power and weight. so my question stands as to what exact size and brand do you recommend for me because i really know nothing about injectors. thanks a bunch

Justin

 

TunerNOOB,

thanks that helps alot i plan on getting it tuned real soon so i guess ill do what you say, just out of curiosity do you know what the flow is on the stock injectors?

Justin

 

Youre not making anywhere near 200 to the wheels (probably not even the crank). So its basically a STOCK LS with basic bolt ons... ya no need for a larger injector... or tuning for that matter.

 

If all you really have is DA with basic bolt on's such as intake, header, and exhaust then sell the fuel rail, and fuel pressure regulator and put stock back on. Keep the stock injectors you have, because you don't need bigger ones at all. If they are leaking because of the rubber seals, get new seals, if the injectors are cracked find replacement stock injectors. And you are definitely no where near 200 to the wheels. It definitely takes a lot more than bolt ons on a VTEC motor to get to 200 to the wheels let alone a LS motor. Also scratch that Idea about getting an AFC to tune. You most likely wont even need a tune with what you have BUT if you are dead set of getting some sort of tuning I would Just get and obd1 LS ecu and socket and chip it with a basemap for your setup from www.phearable.net.

 

ok so i believe you, sorry im not as intelligent as yall and yall make me sound like a retard but thats why im asking the question, because i dont know the answer. but, may i ask why you say to return fuel components to stock? will more fuel not make my car faster? why would they not be beneficial to overall performance regardless of horse power? these questions are not me being a smart*ss im dead serious and curious as to the answers. Thanks for the help.

 

real mature duestch bag

 

essentially no. you've wasted time and money adding the aftermarket fuel components to an essentially stock LS. more fuel will actually hurt your car.

 

Nah man you have to learn somewhere, don't worry about it! I say return them to stock because your car is not going to need more fuel than the stock injectors can handle. Stock injectors are 240cc which is more than enough for what you need. Bigger injectors and more fuel will not make your car faster. It will not benefit because it will dump TOO much fuel causing it to run rich and loose power. Sure if you really really wanted to you could get the 310cc injectors and have it tuned to work fine with your setup, but why? Stock injectors are more than enough, and it would just be a waste of money.

 

wow... stock injectors are good enough for what you have done. and you are not pushing 200 hp with those mods, no ****ing way. the butt dyno is often incorrect. /thread

 

 

To add some sanity back to this thread.

No, I don't know what the stock injectors flow.

However, playing with an AFC is not a proper tune. All they can do is screw with input to make the ECU think a different condition is present than actually is.

Do you have a wideband? Tweaking an AFC with only the butt dyno is asking for trouble. The car might feel faster running lean (under some conditions), but that will destroy the engine eventually. It might also feel faster rich (in some other conditions), but that will kill the cat and your mileage. If you don't know what the actual AFR is, how do you know what direction to adjust?

Bolt ons, run a stock ECU without a hack, and the stock fuel system, and it will be fine. If you want it to run even better, talk with a local tuner and see what software they are familiar with and recommend, then have them tune the car correctly, on a dyno with a wideband.

 

good advice. stock injectors flow 240cc as i stated in my previous reply.

 

ok i appreciate somebody not being a f*cking duestch bag around here. i was told this forum was pretty good with pretty intelligent people on it so i could learn alot and get some questions answered but your one of the only ones thats not a complete sh*t talkin f*ggot and you actually help. thanks. so ill go ahead and return those items to stock and buy some oem injectors. what would be a good alternative to that tho, like cams, or something of that nature?

 

ok thanks ill return those and get some oem injectors

 

good point. i didnt mean get an afc to screw with it myself i meant to go have it tuned proffesionally. and what is a wideband btw

 

No professional will tune with an AFC, because you can't really.

They will use a replacement ECU, or a programable chip added to the factory ECU (depending). This allows them to actually change what the ECU tells the car to do, what it outputs. An AFC only changes the inputs to the stock ECU.

A wideband is an O2 sensor that reports better than the factory one. Stock, they (more or less) only report lean/fine/rich. but not an actual reading of the air/fuel ratio. A wideband will show how lean/rich it is, meaning show the actual AFR, and allow the tuner to adjust the ECU to use the correct amount of fuel, timing, vtc, etc...

 

Thats because you made outlandish claims and had no real idea what you were talking about. Now you know what not to do.
