SAFC with N/A KA Question

[Kaioshin1982]

Hey guys.

I have searched for this topic and I found a thread with couple of good point outs but I still had some questions for it. Please help me out.

1. Someone mentioned to put a 71mm Pulsar N15 Throttle body on it to get more air into it. How hard is it to put the TB on a KA? Is it a direct installation?

2. As far as what I learned. SAFC will be able to add more fuel so what I would need is more air. Besides intake, TB, and cams, whatelse can I do to get more air?

3. How hard is it to tune the safc (kinda broad question... i know i know....)

4.) Is it really worth it? I am eventually going to go KA-T so even if it wont work as well with a NA ka, I will sure to have a good use for it in the future.

5.) If I run too rich using SAFC, what are the good and bad sides to that?

Thank you for your time.

1. dont know, cant be that hard.

2. I could be wrong, but in NA form I'm pretty sure you will want to lean out the mixture for any kind of gain.

3. never tuned myself, my friend has one on his ka-t, i doubt its very hard.

4. I have heard its not very good on an NA, but when you go turbo I'm sure it will pay off. Kinda fun in NA form too, you'll get to know the thing well.

5. Running rich is like running your car waistefully or too safe...if I'm not mistaken.

Hope this helps, I'm tryin to figure this stuff out too lol.

1.) not sure either but don't they have 1.6-2.0 engines? maybe for sr replacement or something not sure either

2.) to get more air, hmm well u need to upgrade ur exhaust also 2 1/4 to 2 1/2. maybe install a header. not sure but replacing the maf sensor for the turbos works not sure if it will work on ur na

3.) u need a a/f to tune it. they cost $$$, but its not that hard. better if u have 2 person, one driving and one checking/adjusting the safc. price about the same or cheaper to dynotune it.

4.) not really worth for a na, if u really want to test it yourself running rich, buy those chips on ebay lol. buy a good catback and call it a day. if u do have some money to spend, i am leaning towards aem management. it should work on na, and definitly if your gonna kat it.

5.) no good will come out of it. your just gonna waste more gas and clog your cat and make ur car slugish.

I would save up and buy AEM EMS instead of SAFC. I have seen it floating around that with AEM stand-alone, DC header and intake they got 27whp out of it.

1. With the Pulsar TB, it is a direct bolt on, you just bore down the sides a little bit from the inside. You can get one from SPL Parts (sponsor).

I've heard of using the H22 or Q45 TB's too, I believe the Q was the biggest, 80mm?

2. Intake, TB, Cams, head work (port/polish, valve job, etc) should be pretty good together. Get some KA-E pistons and up the compression. But if you want air, ya can't beat the turbo .

3. I've heard if you tune the SAFC yourself you just start off running rich and gradually take away fuel. Dyno tuning would probably be the smartest thing to do though.

4. You can get good numbers out of the setup you are thinking about, but I would wait until I got the turbo to start buying parts. Like cams, just wait and get turbo cams when the time comes instead of spending money on something you will want to replace in a couple months.

5. I don't know what any good things come from running rich. You have to buy more gas, you'll start fouling plugs and o2 sensors, and everything NinetyFive240sxSE said.

Hope I helped you out a little bit.

Am I retareded or are the KA-E pistons gonna be a step backwards in uping the compression?

[1991S13]

I have seen threads in the past stating E pistons up the compression when in a DE block. If you search, you probably can find them.

They may not be ideal for his setup because he is going turbo and compression would be too high, but if he did want to stay NA this is a path he could take.

how about a different intake manifold to increase air?http://boostdesigns.com/store/...id=66not sure if there's a difference in performance with this manifold between turbo and n/a though.

and you may not have to add fuel at all...it all depends. you pretty much want a more lean a/f mixture instead of rich to make more power like driftingislame said.

also, if you run rich on purpose with a near stock n/a engine after buying the S-AFC...you've pretty much defeated the purpose of getting the unit in the first place.

Found it, thanks I had no idea that was the case.
