1st paycheck = new parts?

DragonofBC · #1 09-08-2005, 08:16 PM

I started my career 2 weeks ago and I'm waiting on my first paycheck next Thursday. I think I want to get something for the car but I need some advice. My mods are in my sig and I'm trying to figure out what to buy next. You'll notice that I'm running on the stock exhaust and I, unfortunately, have to keep it that way for a little while. I'm thinking something with the fuel system but I don't know what to get first.

First off, I logged a few pulls and I have my boost set to 11.5 psi right now. I'm getting smooth timing curves. I turned it up to 14 and it dipped around 5.7k so I turned it down to 11.5 and haven't played with it since making sure there was no knock. I guess my options are SAFCII, injectors (660s), or fuel pump. I only plan on getting one right now but the rest will eventually be purchased.

The reason I say 660s is because they will flow enough fuel to max out the 16g, which is the furthest I plan on taking this car. I'm not upgrading the turbo again. I guess a question I have is will a 190 be sufficient to handle maxing out the 16g or do I have to go 255 + AFPR?

So what should I get? Or should I consider a FMIC or something else I haven't thought of? I just don't know what will help me the most. Thanks for your input.

If you get 660 inj. you will need an S-AFC.. they kinda go hand in hand unless you have DSMlink...
If maxing out the 16G is something planned... go with a 255walbro and fpr...an exhaust would be helpfull also... everything you have stated kinda needs everything together... more boost needs bigger exhaust to allow it to flow.. more boost needs more fuel...bigger pump...bigger injectors...bigger inj.. S-AFC/DSMlink...
It's kinda a viscous circle but....it's all good..
I was running about 14psi on stock inj/pump/turbo and it ran pretty damn good...

make sure to rewire the FP, if u have a pocketlogger, u dont need dsmlink if u get safc, but basically ur gonna need FP, injectors, safc, and rewire

DragonofBC · #4 09-08-2005, 09:47 PM

I should have included it in my sig, but I did rewire the pump. I kind of got the impression that everything needed to go together, but I was hoping you guys would tell me differently

. I get the impression that the 190 won't support a maxed out 16g then and thats kind of a bummer.

I'm guessing I should start with the SAFC or fuel pump stuff and leave the injectors for later. Will the fuel pump allow me to turn up the boost more than being able to tune my current pump? Maybe I should purchase and closet some stuff for a bit...

I bought a Walboro 255 HP and it wasn't that expensive. I think it may have been the same price as the 190. You just have to look a bit.
I think I paid like 90 bucks for it.

sganc4life_4 · #6 09-08-2005, 10:00 PM

255 is the same price, but u need an afpr too, which you have to be very careful hooking up and doublecheck everything

DragonofBC · #7 09-08-2005, 10:03 PM

the afpr doubles the price the "pump upgrade" in my mind which is why I'm trying to figure out if I can just go 190. If I didn't have to get the afpr, it would be 255 fo sho.

tsipsi20 · #8 09-08-2005, 11:12 PM

You don't need the afpr. Everyone thinks you do. I had this conversation in another recent post. I've had absolutely no problems with mine without a fpr, and I've never heard of anyone needing one. A lot of guys in my area have the 255, and no one uses an FPR. Yes, I will go with popular belief that it helps... but it's not essential. That's just my two cents, and I bet I'll get some criticism for it.

DragonofBC · #9 09-09-2005, 12:18 AM

Your mod list is very impressive but I don't see a mention of a logger or DSMLink. From what I understand, the afpr is used to turn the fuel flow down. Do you have any problems with the car at idle? What does your a/f gauge read when you are under full boost? It would be great knowledge that I wouldn't need a afpr but I've see 255+afpr said so many times that its hard to be convinced otherwise.

Shut the fuck up! 50+ GPH = overflow. End of story. Want to spread bad information? Log the Fuck off!

Walbro 190 rewired supports the following:

9.5:1 (stock) AFR @ BFP @ 15psi = 44lb/min airflow
10:1 AFR @ BFP @ 15psi = 46lb/min airflow
10.5:1 AFR @ BFP @ 15psi = 49lb/min airflow
11.1:1 (fastest flame speed) AFR @ BFP @ 15psi = 52lb/min airflow
12:1 (RBT)AFR @ BFP @ 15psi = 56lb/min airflow
12.5:1 (good target) AFR @ BFP @ 15psi = 58lb/min airflow
13:1 (LBT)AFR @ BFP @ 15psi = 60lb/min airflow
14.68:1 (Sticho)AFR @ BFP @ 15psi = 68lb/min airflow

The Evo 16g will flow a max of 44lb/min. 255lp or hp is not nessessary!

Expect your BFP to be around 50psi if you use a Walbro 255hp and no AFPR. Over runing your FPR like that would turn a set of 660cc's into 710cc's. Not only would you have a major problem trying to get 660's dialed in correctly with a SAFC2 but you would never be running a correct AFR. Tuning would be a nightmare!! Thats not worth it! Spend the $130 and get an Aermotive afpr. Turn down the pressure, add a -6an return line, and screw a gauge into the gauge port. End of story.

Oh yeah 660cc's & reired 190 is a great combo. 190 flows a little the 1-2% more then the 660's are capable of. good combo.

why do you have to keep the stock exaust??? emissions?

Whathits14 · #12 09-09-2005, 02:24 AM

some damn good info from scottsee.
No way in hell you need 255lph pump.
190 flows enough for ~400hp which probably wont happen with the EVO III without some major work. 660s will be good for the EVO III. SAFC when you get you injectors for sure unless you go dsmlink. Looking at your mod list, I would also look into an intercooler upgrade, get it used to save some major bucks or if you are handy, fab one yourself for pocket change (compared to a kit). But before any of that, get some exhaust...if you keep a cat of put a new one in, you will have no problems with emissions. Go for a custom built one and weld on a muffler that does not sound like shit. I have a flowmasters 40 series and it sounds mean...sets off car alarms.

If you do decide to go with the 190, I have one lying around brand new, that I need to get rid of. Make me any resonable offer.

DragonofBC · #13 09-09-2005, 06:59 AM

Awesome info going on here. Thanks scottsee for the nice 190 writeup. Whathits: I sent you a pm.

The reason I'm staying with the stock exhaust for now is kind of a silly reason. My parents offered to pay my car insurance for me through December while I get settled with my new job as long as I don't change the exhaust on my car. It doesn't even make sense to me but as long as I'm getting my insurance paid for, I'm not going to mess with a good thing. Eventually, I'll change it, just not yet.

spyderturbo007 · #14 09-09-2005, 09:16 AM

I'm still on the stock exhaust for a different reason......I really hate the loudness. Scottse says it's because I'm a pussy

Anyway, 2 months ago on the stock exhaust I dynoed 242.5WHP. Since the addition of my UICP I have picked up another 3.7 lbs/min of airflow which should bump me up over 250WHP, easily. Car pulls like a MoFo

I know with an exhaust and FMIC I would probably be over 300WHP, but I am having traction problems as it is......freaking wrong wheel drive.

Anyway, it really depends on how much you want to spend. Here is a FP, injector, SAFC-II upgrade for $619. But you would need a logger to go with that for about another $140. So you are looking at needing about $760.

Might be easier for you to tell us how much you are planning on spending. I got my logger and SAFC-II months before I did the injectors and the FP. That way I was ready.....but it's all up to you.

Thanks spyderturbo for the input and for the link. I think I can put together that kit myself for cheaper than they want, but I am planning on all of that stuff eventually. I think I'll go with the 190 first, then SAFC, then injectors. It seems to be a good order that will be safe. With the 190, I can tweak boost up a little. Then I'll get the SAFC and learn to use it properly before getting the injectors and tweaking more. I already have the logger. That was definitely the first purchase after the new turbo.
