ok so what do you need to do for your fuel to run boost.....and can you use a apexi vafc?....and how do you tune a vafc??...please help!

I guess you could, but for the price get the GReddy E-manage IMO. It's only $299 and does 10x what the VAFC does. Including controlling the VTEC point. Plus it controls extra injectors, ignition when they come out with a fix for the Honda, blah blah blah.

Well, you need to remember that our 7th gen civics have a returnless fuel system...It depends what kind of turbo set up your gonna use, you may have to run your own fuel lines, regulator, fuel pump to make it a regular return system, you have to add a missing link check valve to isolate your map sensor.... Or.....go for an SF Turbo Kit and do no major mods....
It's up to you!!!

the greddy e manage is not all you need...you have to purchase a lot of stuff plus the lap top software.....its a whole process and it would cost a lot more....i was thinking abuot going with the sf but then i dont have the money to buy the whole thing at once. i mean i can afford the apexi safc right now...its going for about 300 or less then that...

Ok, the E-manage ($299) and the injector harness ($30). You can clone the PC cable, or buy it... it's optional and a lot of shops already have it for their own use= you don't have to pay for it. (I doubt that you can tune it without a shop) Trust me... my car is in the shop as we speak. You can raise the fuel +/- 50% with the S-AFC... but that doesn't mean your stock injectors can handle it. And what about when the MAP see's boost, the S-AFC can't account for that... and if you want to go ahead and use the S-AFC with a check valve (missing link), you have already spend more than the E-manage. Tuning either correctly is going to have to be done at a shop anyway with a wideband O2. I'm sticking by the E-manage for the sense of overriding some of the stock ECU. But that's me... go talk to a shop around your area and see what they have to say.

Have you tried sending a PM to SF to see if they sell their fuel system by itself....It sounds like thats all you need...i'll send him a PM.....let you know when he replies!!!!

thanks....i think he does.....it runs around high 500 dollars.....

What about the fuel system that turbo discounters sells? it has it comes w/ tubing, injectors, and everything.

 
Rep Power: 312

The SF fuel system is $525.
(i wrote the parts list and price list)

oh yea, did i mention that there is no tuning required with the SF fuel system? it comes completely tuned, and ready to go. Just a fuel in/ fuel out, power, ground, signal, and vaccume line

Thats 2 hoses, 1 vaccume line, and 3 wires.

weird how everything comes now assembled these days, whatever happened to good old fashioned RandD work . but that is damn convenient catalyst, nice work

You can run an S-AFC with boost, you only need to increase your stock injector size. You do not need a check valve for the map sensor using the AFC. I'm currently running RC 440 injectors and a S-AFC and I am not having any problems and no ECU codes. IMO it's really what you want to do with your car after 6-8psi. If you want to stop there I'd suggest maybe the e-manage although I have no experience with this product. If you want to continue past 6-8 psi then get bigger injectors, run a S-AFC for a while then upgrade to the AEM EMS when it comes out. Just remember, you can't make a decent increase to an injector that is already running at 80%-90%

see i knew that it was just bigger infectors and a apexi safc....thanks n318Z.....what kind of set up would you use???......catalyst i would like to order your set up but i was looking to get a safc......n318z do you have the first apexi safc or the second one?

 
Rep Power: 0

I have the first one

 
Rep Power: 312

how much, on average, do those Safc's run?

Fill me in... you are running (4) 440 injectors to replace the 4 stock injectors? And you aren't using any additional injectors? How high have you turned up the boost? Let me know the details on fitting those injectors in the rail, so I can let the shop know. It's a lot better than extra injectors.

 
Rep Power: 0

Yes I replaced all 4 of my stock injectors and replaced with rc 440's. No additional injectors. I went this route since I plan on building my motor for more boost in about a month. Currently still running on 7psi. Now for the fun part of how they fit in. The stock injectors of course have 2 o-rings on them. Both of them fit onto the rc injectors. But, you need a spacer plate in between the intake manifold and the throttle body. Otherwise the fuel rail will not fit because of the Map sensor.

damn. that sounds fun. At least it isnt like the old DX style injectors.

I don't want to take over this thread to ask these questions, but I will because it might help others.

1. Do you know what the size of the stock injectors are? I have the E-manage and it allows you to put the stock size and the upgrade size so it can automatically adjust the fuel map. I have the factory service manual and it doesn't say anything.

2. When you say a spacer between the TB and manifold, do you mean something equivalent to the Helix Power Tower? Is it the MAP sensor that won't allow it to fit, or is it the TPS (mounted on the TB)?

Thanks again... anything beats spraying fuel into plastic (that's gotta create some kind of residue in the long run)

That is a good question, I would like to know also? Did Chilton or Mitchell make a manuel for our cars yet? I can't find one here on Maui.....we too laid back!!!

I believe the stock injector size is 240. The spacer I'm refering to is the one that comes with the Turbo Discounters kit, it works very well. And yes it's the TPS not the MAP

Gotcha... thanks a lot.

240? ok thanks!!goota keep that in mine.....

do you have a picture of this spacer plate your talking about?

and does anyone know why 450's wouldn't fit off a DSM?
and if they do would a resistor box be necessary?
