are 740cc injectors to much for the apexi afc neo2?????

[shmiddy]

so i was thinking about getting nismo 740cc injectors to finish my sr. but the guy who does my tuning said that i should get some sort of stand allone or a re-tuned ecu for that kind of injector rating. he says that with the neo itself it wont work as well.. is that true?? this guys almost rewired my whole sr harness in a few days so i have allot of confidence in the guy, just want a second opinion.... any afc pro's on zilvia??????

[chituntang]

neo cannot handle that much...
If you are using 740cc injectors, I think your setup needs standalone anyways.

afc's are shit and i believe 550cc injectors are the limit over stock! Look into a jim wolf ecu or enthalapy ecu!

[shmiddy]

^^^ thanx guys

damn me for being a cheap bastard :-/

[dookiedang]

go power FC! its the bang for your buck for a stand alone ecu well that is if you wanna stick with Apexi. theres hks Fcon Pro too, that works really well. next step is Aem EMS if you wanna go Big.

[dookiedang]

Power Fc Ftw!!

hahah of course everyone like AEM EMS. it cost almost as much as an sr front clip.

[shmiddy]

ok one more question guys.. how much hp can i get out of a sr with 550's

set up:
s13 blacktop
full t3 top mount turbo
walbro
sard fpr
and freddy intake manifold..............

I'd be hesitant even to go to 550's with an safc neo, i'm running 480's and a z32 maf with mine, and i still have to take out almost 20% fuel up top (though thats become 15% now that i'm running a 25% e85 mix). Just remember the more fuel you have to take out or add in, the farther away your timing map will be, and that's what causes problems, especially if you're not monitoring knock.

[Sileighty_85]

550's will get ya 300-375 reliable I think.
depending on you HP Goals if ya want around 400+
just go with some 740's its better to have more fuel then not enough

[S14DB]

50% is the bigest you can go on a SAFC style piggy. So, 50% of 370 is 185, 185+370 i s 555. 550 would work but is on the edge.

You are still faking out the ECU and Nissan ecus alter the timing based on load. I would be worried how much my timing would be off. High denotation and crazy EGT risk.

OK for trimming a Tune. But I wouldn't tune with them.

AEM you need to get a replacement trigger wheel and modify the CAS.

The ignition map will sometime sweep off track with load which could spell disaster.

They are now equiping the newest batches with the upgraded trigger wheel that replaces the stock on in the cas.

JUST FYI
