Default H22A injectors what do i need???

ok im doing a h22a swap into my 92, i dont have injectors and am looking to buy new ones. but im the type that hates to buy a stock part when you can get a better one for a couple bucks more. so im looking into bigger better injectors.. any suggestions?? have 8 basic bolt ons, what else to i have to change to run slightly bigger injectors? and if anyone knows pros and cons on peak+hold and saturated??

Um.. If you staying OBD1 then you NEED Peak & Hold Injectors.. If you're staying N/A with only some bolts on's then Stock Injectors will work fine.. They're 345cc for the H22A and H22A1 OBD1 Motors.
Saturated are for OBD2 ECU's and are smaller cc's, stock of course.

From the Factory the Injectors cost $116 a piece so it's over $450 for all four..

You can find them used for cheaper.. Some people practically give them away for the prices they sell them for..


*I have a set also if you would like them.. Just let me know..

the stock OBDII injectors are good to ~200whp

stock OBDI 345's are good to a little more than 200whp

until you are making beyond 200whp, you dont need to worry about changing injectors.

^^Yeah.. And you'll need a stronger, I guess that's how you would word it, fuel pump. Like a Walbro 255lp..
And an Aftermarket Fuel Pressure Regulator would help.
Aftermarket Fuel Rail of Course..

Might be others, but that's good to start with..

you lie sir. not even 350hp motors need a bigger fuel pump or fuel pressure regulator and aftermarket fuel rail is just stupid unless you are makeing more than 400. that is a load of ****!!

talk to a tuner they know their ****. you cannot just put bigger injectors in. lets say for example your computer has your 345 injectors running at 65% of their capacity and that is 1 gallon per hour (not even close to true just an example) and you put in 500cc injectors. your computer will have them run at 65% and at 65% of their capacity that is the same thing as 3 gallons per hour. see the problem here??.

so if you want bigger injectors you will need something to tune them with. i do not suggest the vafc or safc the are only band aids. get something like a stand alone. so just keep it simple and leave it stock.

if you have simple bolt ons then just get the stock 345cc (peak and hold not saturated)injectors. you can find them cheap. check out homemadeturbo.com they have them all the time.

lol, Sorry.. I didn't mean "Need" those items.. Just meant that they could help.. And I wasn't trying to say they'd be needed for just simple bolts on's and such.. I meant after that, after more than just bolt on's...

^^Yes yes, I agree with that completely.. I didn't ever say he'd need bigger injectors.. I know the Stock Injectors are enough for most applications.. I don't think I stated that "bigger" injectors were needed..

Sorry for the confusion..

i dont have a prelude either and i also know other accords using the STOCK FUEL SYSTEM and making over 300 whp. so obviously his calculation is wrong. i was exaggerating the knowing nothing. he could be a genius i have no idea but i know of plenty of accords making more than 250whp with the stock pump

that doesnt mean they arent going passed the safe limit of the pump . You dont want to run fuel devices to their max, same goes for pretty much everything else. Just like injectors; your not supposed to run an injector beyond 85% duty cycle.

well, i meant safely. sure you can push it to the max, and it will probably handle 300whp, but do you really think a pump is going to last very long running it at 100%, i wouldn't think it will be all that great for it.

If you care, here are the flow charts i got from RC engineering, and i plotted it on a graph.

it's not like i am pulling these numbers out my ***, so calm the expletive down. just cuz you saw your friend's cousin's sister's massage therapist make 300whp on an accord pump, doesn't exactly mean it's safe.

Did they have aftermarket injectors? Maybe they just had higher pressure injectors or an adjustable fpr. Although higher pressure is no replacement for volume. Just my .02.

seriously dood, do and think what you wish. if you like to half *** everything, that's fine, it's not my car, and not my wallet.

I already showed you the flow numbers of a stock accord pump, if you choose to ignore it, good for you.

i wouldnt call it half assing. just not spending unneccessary money. it will support the hp. i see what your flow chart says and you are right it is pushing it however it will work and if you know what you are doing it will last a long time

RC Engineering did not get to where it is by spreading bad information and lying. If they say that they would not recommend usign a stock pump to go beyond 250 whp I would jsut go buy a Walbro pump.

Its a lto easier and cheaper to buy a $99 pump and put it in then it is to blow your engine up.

Why in the world would Honda make a stock fuel pump that would support 300whp? Wouldn't happen.

^^I couldn't be positive about it... But I wouldn't say "Honda" actually made it.. It was probably made by another manufacture and Honda uses it in their cars..
So it would be to the Specs that the actual manufacture made it..

But as always, I could be wrong..

why in the world would they make axles, trannys, internals, sleeves etc to withstand 300 hp? why would they put injectors that will support 250-270? no one knows but **** happens
