ok since I am putting a turbo on, I wondered if I needed to upgrade my injectors at all what all is required when doing that? First, what is the stock size of the injectors in my car and what are some suggestions for upgrading if I need to? I am running no more than 10 psi so I doubt I even have to upgrade but still just wondering. If I do, what else needs to be done since hondas use a map sensor instead of a mass air, I guess the only thing that needs to be done is the ecu needs to be tuned for the new size?

most stock honda inj. are 240's .anything over about 200 hp u will need injectors. 10psi ~ 550's will probably suit ya well.

You wont need to upgrade if your not going past 10 psi, stock is 240cc. How was that kit on install, and what are your thoughts on it?

You can't judge injector duty cycle by psi on a turbo kit.
240cc stock injectors peak out at around 200 whp.

You should never run an injector at a high duty cycle as you can run into issues.

If you plan on trying to make over 190 whp (200-300whp) I would personally recommend 440cc-550cc injectors, a real fuel management system such as an obd1 chipped ecu running crome, hondata, ectune, neptune etc.

I would also recommend a walbro 255lph fuel pump.

If you are going to eventually run more then 10 psi I would also recommend an aftermarket map sensor such as a motorola 2.5 bar or gm 3 bar.

Sorry to bring bad news but... Just a warning before you install your cheap turbo kit. The turbo seals will probably fail upon startup or within a few weeks. I have yet to see a cheap ebay turbo kit last more then a month or two.

I also just noticed your running an automatic.
There is not one factory ecu based ems that officially supports the use of an automatic tranny. You will end up having to look into a piggyback fuel/timing control unit such as the AEM FIC

with boost larger injectors are probably a good idea over stock. aftermarkets will flow better and probably give u better performance anyways.

The size of your injectors really doesn't matter if your car is not tuned properly (engine management system)

a/f r's are key, get crome

all it takes is tuning, tuning and some more tuning. took me 3 times till my car was where i liked it.

I take it your pretty knowledgable from your thousands of post (literally). Do you have voltage offsets for crome, for rc 550 or 660 high impedance injectors ?

Funanin

would greddy emanage be what i am looking for or would i need the ultimate? or something completely different?

z6hatchboy

^ You'll be fine with crome, or neptune and its a fraction of the cost as emanage (which from my understanding can only be tuned by a qualified greddy person?)

Funanin

no im good with tuning I have something called a tweecer for my mustang and I went to school for advance engine performance before I got hurt, but tell me more about this crome if I can save a few bux and do the same thing then why not?

a/f ratios are 1/2 the battle.
Ignition timing is really key as a/f ratios are actually the easy part.

Figure it out with a multi-meter your self. Every car is different

Crome does not fully support automatics. Any use of an automatic tranny with crome is experimental. We don't even support it.

Funanin

ok well i just ordered the piggy back for the ecm and im gonna try crome i guess. I am also gonna look into hondata

sensys01

if crome doesnt support a program for auto go with uberdata... imo it is a way better fuel management program.
just my .02
