Ok, its not like im gonna die over it but i bought my 87 turbo II like a month ago, the guy told me he bought it the way it was never did anywork to it (but it was rebuilt, but i dont know what its got done to it now!) so i assumed it was stock and it had only a fuel cut defender on it, the crappy plug in at the boost sensor one. Well i ordered a Apexi S-AFC so i could trun up my boost. Well I'm tryign to install it about a half hour ago and i pull back my carpet, take off teh computer shield... and what did i find.. I found an HKS Fuel cut Defencer, and an HKS PFC F-CON Fuel computer system.. I'm new to the turbo scene so can somone tell me what i should do? I mean i still have the S-AFC I wnated to install but i dont think i should now. Can somone tell me in all seriousness what I got myself into and what I should do?!

 

thank god first then sell the AFC for some new fuel injectors.

 

lucky bastard!!! j/k... seriously you got a deal on that those are expensive... ya sell the apc for some bigger injectors.... take the car and get it retuned is what i would do

 

Why should i get bigger injectors? I herd i can still hook up the afc to the f-con. I dont know anything about this stuff, somone has to explain to me what this f-con is doing for my car all i know is it mod's my fuel. Crap, i dont even know if it has bigger injectors in it, I dont know what's done to it now at all..

 

Ok, I just read about it at HKSusa .com and aprently its an 1100$ fuel system and now all i guess i need is a bigger turbo and a front mount right lol. Unless I can get any other suggestions, yeah and also i gotta find out how big my injectors are. How can i do this?

 

You got very lucky. On the HKS website, the PFC F-CON is listed as $1135. Basically, it can do what the S-AFC does but better, plus some other stuff. The bigger injectors are needed to give more fuel to a moddified engine. Considering the fact that there was a PFC F-CON already installed, you might already have bigger injectors.

 

what do ya want for the safc?

 

Well i had some problems with my idle and some fuel issues and i figured i try each one and figure out the differences and find which one i found more sutible for me.. I found i dont have bigger injectors, and when i tried just the afc my idle problems were corrected and i have a prefect idle and a few others were fixed like my funky air/fuel readings while cruising they read lean as hell..and when i ran it stock with nothing it didn't do that..but when i put the f-con back on it all started over again..so i stayed with teh afc but i think later down the line i will reinstall it when i get bigger turbo yadda yadda..but if anyone is interested in it i might let it go..PM me i guess..

 

it would be funny if he had some bigger injectors aswell. lol. lucky bastard.
