My Setup ??

[98GSXboosted]

Hey my mods are as follows
14b
Intake filter
255 walbro
slimfan
EGT, A/F,Boost gauge
S-afc II
short throw
FTS AFPR
Greddy rs BOV
am currently running 15psi
Well i just bought some new parts
RNR Racing turboback W/ Highflow Cat
RNR Racing FMIC (Race Kit)
Injen Intake w/ K&N filter
and an EVOIII 16G
Obviously i will be replacing the 14b w/ the evo, and i am running on stock injectors w/out a DSM link will I be able to run this setup w/out both of these? Should i just turn down boost to 10-12?

 

[hereitcomes]

the stock injectors are good to 16PSi before fuel cut, and boost related problems.
You have an SAFC and that should sufice for your tuning and able to control some of the ratios on the air/fuel. the evoIII turbo setup will allow for better air volume and better flow than a 14b. you can turn it down to 12 and fiddle with the settings on the SAFC-II and get it to how you want. good luck man.

I would just try to pick up a set of 650cc injectors to go on top of everything else you have. From the looks of things, with bigger injectors, you should be able to support at least 300-350 horses. Usually, you can find a good set of used 650s for ~$150.

Your setup looks awesome, tho, man! Pretty much where I am looking to end up with my 1g.

Just to note, fuel cut is not based on pressure, but rather airflow through the MAS. The Evo3 can flow a good bit of air and I wouldn't be surprised if fuel cut becomes your new best friend. Look into some injectors as soon as possible.

I agree that 650s would best exploit the E3 16G by far... but the SAFC will not compensate for the 650s with out serious issues. I know from personal experience... i think this:

...get 550s if you want good power and a fun car now
...Or, get 650s and a chip burned for 650s and fine tune with safc if you want to max this turbo out and see what she'll do
...or go DSMLink if you want to go all out with this motor and go to the limit of the bottem end.

YES! Im glad you caught that... I was even talking about injector upgrades for my car the other day and decided to go the 550 route so I dont have to chip my ECU.

...get 550s if you want good power and a fun car now

With 550s and the setup he is talking about, he should be able to support up to about 450 HP, right? Would that be getting close to the limitations of the 16g? Im pretty sure that the 14b can put out 300-350, cant it? Only bad thing about the 550's would be if you wanted to go higher than that?

Im just asking because I am going to be doing an injector upgrade very soon and want to make sure I have my info straight. Also, with 550's, does impedance make any difference?

Do you think i can get bout 320 whp out of this setup? I can't wait to install now

 

[98GSXboosted]

I just got back with my new parts. They are RNR Racing FMIC w/ piping, RNR Racing exhaust 3in turboback SS w/ highflow cat, EVOIII16G, J-pipe, and Injen intake w/ filter

jesus christ, man.... i wish i had all of that stuff sitting in my living room

honestly, with that front mount and exhaust and the means to tune you should be able to get about 300 even with the 14b. It might be difficult with the 450's though. You really need to pick up some bigger injectors so you can crank the boost up. you do have a manual boost controller, right? just keep a close eye on those EGTs.

i am guessing your IC piping is 2.5" thru out? I cant tell with the exhaust, how big is it?

I am at 93% duty on my 550's on my small 16g, I am currently flowing around 34-35 lbs per min. The Evo3 has done 44 lbs per min, 550cc is just not enough injector for the Evo3.

there you have it. i wouldnt put the 16g on until you get bigger injectors. i honestly havent looked in to the 16g that much so i dont know everything you are going to need. you can still make hella power and have a good time with the other mods and 14b until you can support the 16g. just dont crank the boost too high cause fuel cut is not a fun thing when you are tryin to get down.... !

anyone with a setup similar to his with a 16g, as well? what are you guys running and what is your setup to tune with?

According to DSM_Tuning_Sheet_v2.1 found elseware on this forum, the maximum horsepower 550s will support on a perfect tune is 395.28 with a 2g FPR. That's at the crank. You will be pretty close to the max of your E3 16g at that point. Although it has been proven that you can go higher HP with the E3, mostlikely you won't. I say go 650s. You will have room to grow and you should be able to support a 20G upgrade later. I think all the power you could want on the streets can be had with 650s (but there are some psychos out there who want more ).

About impedance: here's good info on injectors here. From my understanding Turbo DSMs have resistor packs and low impedence injectors. N/Ts have high impedence and no resistor pack. So if you want to use high impedence injectors then take out the reistor pack. I don't recommend high impedence because they usually have longer deadtimes which give you less usable injector pulsewidth per revolution. This gets troublesome up top in the rev range.

 

[2gGSX]

Stay with low impedence injectors. The problem they are talking about with the AFC and 650cc injectors is that the AFC has to take out so much airflow that the ECU bumps up timing, significantly, which causes knock. Someone else may be able to chime in with advice and experiences using this setup.

My advice is to get the 550's. There have been many people who are over 300 whp with your setup on pump gas. This would be the upper limits of this setup however, but if you increase your base fuel pressure you will be able to squeeze out some more fuel. For example, if you up your base fuel pressure from 43.5 to example 55 psi, then they will flow sqrt(55/43.5)=1.1244 times as much as before, squeezing just under 620 cc/min out of your injectors. This is only an example mind you.

Also, as an example, there is a certain 2g AWD with an Evo 3 16g in the 11's using 550cc injectors and RACE GAS. This is the key, and what will allow you to go much further than what people are saying with 550cc injectors.

DSMLink or a chip is what will allow you to effectively run bigger injectors, but will be relatively more costly.

Yea i have a MBC but i just lost the spring and ball in it so no mbc as of now, i just ordered a new one. It's a 3inch turboback. My egt guage is broken as well, its autometer procomp got probe installed ran all wires but gauge doesnt work. I need to buy a new one just havnt had 100 to buy one yet.

I am using a small 16g, relevant changes in my setup would be cams, the EVO3 manifold and the EVO3 TB. If you're going to do something, do it right. I'm kicking myself in the ass for not getting bigger injectors in the first place, I just ordered 880's. The 550's have done me well, 7.84@89 3 weeks ago in the 1/8 mile. They are close to being done though, and with my upcoming Green swap I need something a lot larger.
