So im looking into buying this piece of art, and was jist wondering what kind of work ill have to do, and after installation will anything else be needed such as professional tuning?
Before that os this part even compatible with a 5s-fe

Neo's are stupid expensive and you are better off getting a used Apexi SAFCII. Similar wiring install.

The install is fairly simple. Id recommend solder/splicing into the ECU wires that you need to connect to. There are specs that are listed on the site as to how to set up the SAFC for your stock 5SFE. If you cant find it I will try and recall what my settings were when I was running my SAFC on my stock motor

Where would I look to purchase a safcii, im gonna try ebay now but that said how much should I pay for a second hand one, that apexi one is going for $460, also ive got aftermarket headers and a cold air intake if that makes any difference.
Ive also never soldered as this is my first car (still learning), but theres always a first time I guess. Thanks in advance

Carry on with this thread.

they will go anywhere from $100-$250.

$120-180 is the reasonable price range you should pay for one.

Its not too difficult to solder it in, but since youll be tapping into the ECU which is kind of important, I would practice a few times with some spare or scrap wire. Along with splicing into wires as well btw....which in the case (the way i did it) was to strip off about and INCH of the wires casing with a blade and wrapping the wire from the SAFC around it and solder it together.


before I go all out into explaining the process go get the SAFC first and come back haha

you should also be warned that you wont really see a large increase of power from a tuned SAFC on a stock motor (It helps get a little more power from 4k RPM on which is what the 5SFE needs), regardless of your bolt ons. Camshafts would be your best bet along with the SAFC to see some actual gains.

just something to chew on. I saw go for it. Its a great way to learn new things

Thanks guys, ill probably go to the buying/selling section and see my luck there.

Instead of stripping wires you could always use quick splicers, saves time and if you manage to splice the wrong wires the patch up is easier to do. However if you want a professional looking job and you are serious about keeping the system in the car, do as tiga said and practice soldering wire. Definitely the SAFCII would be the one to consider as it is the cheaper option than the neo and still a very functional system too.
