Stock GSX 16G upgrade?

[oplix]

I know this must have been answered a lot of times but I felt special enough to start a thread Anyway I have a completely stock 95 GSX and was wondering if I wanted to upgrade to a big/small 16G what kind of supporting mods would I need. Preferably if someone could tell me the order of which to get the mods as well.

Greatly appreciated

You can run 8-10 psi on the 16g, any which one you want. I would get the evo one though.


This can hold you over till you get the supporting mods.

You will feel a difference in the t-25 vs the 16g.

So I can just run it with a stock configuration? Do I need to retune the car afterwards? Also do I need a boost controller? Thanks!

also how much horsepower would a evo iii 16g add?

If your going to run a small 16g or a big 16g, you dont need any mods to support it. i had a big 16g and was boosting 14-15 psi w/out any problems. I also have a manual boost controller but I dont think you need it though. It's really up to you.

If you want to do it right just get a 190 fuel pump at the very least, some injectors (550cc), and then your golden. You probably wont get boost creep with stock exhaust. Then you can pump up boost to about 18-20 lbs. Of course that is if your watching stuff with a logger.

If you don't do any of that, keep it about 10lbs or less. Expect your power curve to shift to the right meaning that you will be faster in the upper rpms. Probably the same in the lower rpms though. Nobody can tell you accurate horsepower gains but to be safe a jump in about 20-30 horsepower to the wheels would be a good guess if you run it stock. Lots more if you do the supporting mods.

Definitely do the supporting mods though. You're gonna spend all that money on a turbo you might as well get full horsepower from it.

That is why i said just run the 16g on 8-10 psi.

He still can afford to run the turbo, not risk blowing the car, And afford to get the supporting mods later if he wishes to add more power.

You should go ahead and catch some of the maintenance up and get a boost gauge if you dont yet have one.

Mbc is not really needed yet, wait till you get a logger.

Golden? Then his car would run like crap. You'll also need some sort of tuning device to control those bigger injectors. S-AFC, Dsmchip, DSMlink etc. I would say that the logger is necessary if you do not get dsmlink; it's always good to see what's going with your car.

But like others have said, you can run low boost (I wouldn't go past 12lbs) with the 16g on your stock fuel system and feel quite a difference over the T-2 small.

 

[webconnect]

Oh yeah I forgot engine management. Get a safc or the de facto - I could code this program in 10th grade- dsmlink

 

[packinkimber45]

I believe you dont want to run past 12psi on stock fuel set up or you will overrun your injectors with that 16 g past 12psi. Hope that helps, anyone correct me if I am wrong. I would get injectors 650/750cc, walbro 190 and something to tune with. I would go 750 so you wont need bigger injectors later.

 

[Toxicangel]

if you just bolt on a 16g with no supporting mods, your car is actually going to run slower. the turbo spools slower that the stock t25.

1. need 650cc injectors
2. dsm link or at least afc
3. boost gauge
4. boost controller
5. at least 190 fuel pump


not in order.

dsmlink is really nice but too expensive right now. I guess ill just start with a new pump and injectors then get a boost gauge and controller.

oh by the way, will bigger injectors and fuel pump decrease my gas mileage?

ADDED:

Would a AEM Tru-Boost Gauge be sufficient enough to function as both a gauge and a boost controller? I'd like to have the least amount of extra gauges and other aftermarket things inside my car.

 

[BoostedinSoFla]

Boost gauge will go inside, the MBC will be in the engine compartment unless you opt for one of those fancy in-cabin boost controllers.

Really? Slower?

Where'd u get this from dude? Do me a favor. Go out and try to race a DSM w/16g on low boost while you're still on your T-2 small (on stock boost) and see what happens. Any turbo is better than the T-2 small.

A AEM Tru-Boost Gauge will function as both but its expesive $329.00. manual boost controller $100 & boost gauge $60-$120.

EXACTLY.
if you remain stock and just add a 16g you will be faster, not slower. thats crazy talk. the 16g has more room for flow in the compressor housing (because its bigger). that means more power. add yes the 16g will spool slower then the t25, not that its at a degree were you can notice so it really dosent matter.its not like your getting a gt40r. but anyway thats the whole point of having a bigger turbo. you trade your quick spool for more high end power.
but most important, and trust me on this. you dont need to mod anything on your car if all you want is to drive around normally with a 16g, and a little extra power. all the fuel and air components will handle the 16g to about 17 - 20 psi stock, all though i dont recommen doing it. i have had first hand experience with the limit our stock fuel systems can take.

16-20psi!! thats why there are only a few runing dsm's.

 

[210 dsm]

tell me about it

 

[Afroclipse]

Guys this is repetitious, if he does a 16g search he can find his answer, there are threads like this all day everyday and it doesn't make any sense. If you look up on the top there is a tech guide which teaches you how plus RRE has on too come on guys.

Now to answer your question, this is the route i have taken.

1. fuel pump + rewire
2. mbc
3. boost gauge
4. logger logger logger logger logger logger logger logger get it, logger.
5. I have a chip but you should run with an safc
6. 720 Injectors, 450's are known to have balls see how far they take you(logger, logger)
7. turboback ( complements the system, so does porting of mani, or, and Ex housing)

im sorry this is so frusterating for you guys who have been here a while, but im doing the same thing, just got a 95 gsx (auto), the day i bought it the seals in the turbo went out, im new to the dsm seen and im deff not a mechanic, so instead of rebiuld or buying stock, im upgrading now but broke as hell, i just want clarity on the situation, so this helped alot.

just one question tho, without a contoller, how do you control how much psi your pushing, cant afford to blow something now?

 

[Afroclipse]

You can only run what the solenoid says and that is the stock 12-14 I think.

 

[dj_remy]

okay cool, thnx, and i guess with it bein an auto, no real change of over-rev or to much boost for now, thanks man.

is that a safe range, i would think so?
