i've wanted to upgrade my fuel system and just want to think what's best
thanks in advance
 
What are your goals for the car?

If you plan on sticking with lower hp numbers, I'd upgrade the fuel pump to a 190, get an S-AFC, and get some 650cc injectors.

If you plan on going a bit higher, say between 350 and 500, I'd get a 255 pump, an AFPR, and whatever size injectors you want. Anything higher than 650's will not be able to be controlled by an S-AFC so you'll need either DSMlink or AEM EMS. Once you get into that, you're getting into some pretty serious stuff.

That kit would be something I'd recommend for a high hp car (say in the 500 - 600 hp range).

Let us know your goals so that we can help you out better (and by the looks of it, maybe save you some money)!
 
All you actually need from that are the pump, injectors, AFPR, and whatever engine management system you choose. The stock fuel lines are hearty enough for sub-500 whp goals.
 
i'd like to put more stuff to my dsm and try to max it out with out having to go internals and to see how much i can push and just have it at that, never run at the track before so, kinda new but willing to have a nice and quick dsm so if anyone have good ideas, that will be great,
i'd like to get these, 750cc,255 walboro pump,arpr,and rail plus using apexi safc neo, plus get the apexi safc to control my fuel level because my high end seem to hesitate with my 16g, do i need to get any wideband or any dataloging stuff too? i mean these are pretty pricy,by the way what does dsm link do?
i'd like to know what people have in there dsm/or their setup so i'll have something in mind

Setup sounds good but I think the safc can only control 650's. If you go with 750's you'll need dsmlink. You don't need a fuel rail, the stock one is more than sufficient. A wideband would be nice to have one you start tuning. A logger is a must once you start tuning - just so you know, dsmlink logs and tunes so take a look at it.
 
Don't bother if you have to ask if you need a wideband, then you are not expeirenced enough to take this level of fuel managment.

This is not to insult you, but save you from future head ache. With the turbo you have, I suggest a MAFT Blow-through setup with 550cc injectors, 550cc injectors, SAFC, Walboro 255 (rewired), and a AFPR kit.

Wideband is optional but a very good idea if you plan on tunning with a SAFC.
 
DSMlink is the shit, its a piggy back system but does almost everything a stand alone does and it also logs so you wouldnt need to spend any extra cash to get a logger and costs only a couple hundred more than an SAFC.
 
I run a 16G as well and if you check my profile you will see what I have. The only thing that should have been done differently is the injectors....if I had it to do over again I would have gone with a set of 850s.

DSMLink (everything...DSMLink, laptop, ECU + socketing, etc.): $900
Pump and injectors (255/625s): $350
AFPR: $150
Fuel rail feed and return SS lines: $175

All new for a total of $1575, however the fuel system alone is only $675.

$1150 with a SAFC for a controller as opposed to $1575 running DSMLink...I'll spend the extra $400 for DSMLink and be done with it. DSMLink not only is a fuel controller, it also controls timing as well, plus a slew of options that would make your head spin. On top of that it has the ability to log ANYTHING that the ECU sees, hell it can log when your AC compressor comes on or shuts off, so it can see many functions that a basic logger would never see. Go to DSMLinks website and be overwhelmed with all it can do.

Add a WB for $200 and a MAP sensor for $100 and you will have a very nice tuning package.

But as stated, for where you're at, the SBR kit is way overkill and expensive.

DSMLink is VERY not a piggyback. It's a standalone that uses the stock ECU. A piggyback interrupts the signal from MAF and injectors, this tool can change almost every parameter of the ECU settings.
