I know this question may have been addressed a few times but I still can't find the answer I'm looking for. I currently have a 94 rs integra and will soon begin installing my turbo kit. It consists of a T3 super 60, 28.5x5x2 fmic, equal length tubular ss manifold, cartech adjustable fmu, rx7 bov so far. I need to know if I only run ~ 5-7 psi daily driven, do I still need an inline fuel pump to complete fuel management? Or would it be ok to run my stock intank fuel pump?

Thanks

 

honestly my first thoughts were to go with piggy backs and **** like that.. but then i was worried about reliability and what not so i decided to go with a Hondata S200 w/ Boost. with that all you would need is some 450cc injectors (DSM injectors) which u can get for like 50-60 bucks used for a whole set. stock fpr and fuel pump is OK for low- mild boost using a hondata. U will also need a chipped OBD1 ecu.. if you are obd 2 find a obd1 , perhaps a p28 , and send it out to be chipped by hondata or find someone or if u think u have skills with electronics, goahead and chip it. WHen u purchase the Hondata interface (S200) it comes with a CD which will explain how to chip the ecu if u decide to.. oh yea if u are obd 2 now ..when u get the obd 1 ecu u will need a obd 2 to obd1 conversion harness..and thats really it.. then have it tuned..

 

Thanks man but i'm not using hondata, too expensive right now if u know what i mean, i just wanted to know if the adjustable cartech fmu is enough for fuel management on a low boost application.

honestly , your better off with the "AFC Hack" ..u get a SAFC or VAFC whichever you want and then 450cc DSM injectors..

EDIT: to really answer your question, a cartech FMU ALONE will not cut it.. you should get bigger injectors and def will need an inline high pressure fuel pump.

 

Thanks man that's exactly the kind of answer I was looking for it's just that some people around the way were saying that I don't need all that fuel to push low boost.

hondata is 445 for s100, and 600 for s200 and can be had cheaper used. few hundred for injectors + intank pump and few hundred for tuning.. its a bit out there, but if you're going to end up gong for more hp, you already waisted money for fmu and inline pump and afc. subract that from hondata setup to see the difference, or add it to hondata setup if you're going to get one later.

 

I appreciate the input, but I already established that I don't intend on getting hondata, it's not like that's the only way to turbo a honda. Besides this is a custom "budget" turbo setup and I don't plan on raising the boost past 7 psi. Is hondata the better solution to tuning? It probably is but unfortunately I don't have that kind of money to spend...

 

With a FMU, you definately need an inline fuel pump. Otherwise, you will not to be able to maintain the flow needed at higher fuel pressure.

A FMU does not necessitate larger injectors, that is the whole point.

 

if you aren't looking to spend a lot of money on engine management...look into the free rom editors like Uberdata and Crome(pretty much just like Hondata, but FREE!) most you'll spend is about $120 for a burner and chipping supplies...but it'll give you way more piece of mind thna dealing with FMUs, IMO

matter of fact what do you know I'm selling a chipped/socketed ECU for a P75 B18 LS...perfect to run Crome or Uberdata on

 

I appreciate the offer but I don't know sh#t bout that stuff, let me do some research first then i'll get back to you if you still have it of course

 

yeah im doing the same route as b18badboy, im on a low budget, so im going to get the vortech 12:1 fmu for like 70 bucks and get the inline fuel pump.... we all know that hondata is way better for our cars, but all your FMU haters out there, suck a ****, and give us money if you want us to run hondata....lol

 

Atleast now I know I'm not the only guy boosting a honda without mad money to spend

 

you'd be surprised if you'd do a little more research what quality things you could get for your setup that actually don't cost a lot of money but you think they do...ignorance is bliss, good luck

 

I understand your on a budget here, but if there is one thing you shouldn't skimp on, it isn't fuel management. Mayeb there are other places you can cut the cost of your setup in favor of something a little better? Otherwise it seems to me as though the FMU w/ missing link may be the only way you can afford, and if that is the case. It wont hurt you that much. Eventually i would look into a better fuel mamagement system. Purely up to you, but spend where you will and want what you will. But no matter what, enjoy it while it last. Who cares what you do as long as it suits your needs.

If the minimum is what you want go for it, nothing wrong with that. Have fun and enjoy it while you can. Thats all that matters!

Good Man

 

Go with Uberdata. Better than the hack and definitely better than the fmu. You would need bigger and injectors preferably dsm 450cc injectors (50 dollars), a resistor box(5 dollars), and a chipped obd1 ecu, which costs like 30 dollars to do yourself.

Also I would recommend going with a walbro 190 intank fuel pump (80-100 dollars). People have gotten away without using one, but I would go with one.
