Turbo upgrade question?

[jdms-14]

I have a s13 sr and I just upgraded my turbo to a s15 (t28) with HKS actuator, i also upgraded injectors to 550cc...
heres my question:
-is it normal that the injectors make more noise? i hear them loud, and they are working perfect, i just wanna know if is normal?

-also, i havent had the chance to get tuned, so is it safe to drive the car like that?? or should i just wait?

-a friend told me to smell the oil, and if it smells like gas then i should change the oil and not drive it, true or false?

as of now the car is sitting i dont even wanna drive it because ive heard is not safe until it gets tuned, can i just used the stock injectors until i get tuned or is this a bad idea?

any advice is welcome
thank u

God Bless

Not safe at all to run bigger injectors without a tune. You will run too rich. You can use the stock injectors with bigger turbo, but need to stay out of boost, or at least not turning up the boost because you will most likely need more fuel to run a bigger turbo.

all you need now is z32 maf and safc2 and you'll be making good power. all you're gonna do is foul out your plugs. you're gonna be slower now than with your t25 since you'll be running so rich, so y even take it out. get it tuned, but you won't hurt your motor running rich. once you drive it and feel how slow it is compared to your t25 you'll be like , bah i'm getting tuned. and DO NOT think it's a good idea to compensate for your extra fuel by giving it EXTRA BOOST lol :P just givin you a hard time.

all in all , you could have the best parts in the world on your car, but if you're not tuned for em, or have a crappy tune, you'll get owned by people with average parts and a good tune. it's all in the tune man. you asked some good questions. gl , post your dyno's and don't take the stock maf passed 270rwhp, bad idea. laterz

thanks mang, by the way i do have SAFC2 and m60 maf (maxima maf)

i actually live in ATL and im member of 240atlanta.com... ive seen u b4 too, sice u live here, where do u recomend me to go get tuned???

I think im just gonna put the stock injectors until i get tuned, or to drive the car to the dyno place since is like 30min drive..
what do u think?

Turbo Dave or Rob at mainstream performance. Turbo Dave'll look at ur car making 280rwhp. you'll be like "DAVE MY CAR'S SO FRICKIN FAST 280RWHP i've never had it that high, u rock!!!" he'll be like "hmmm 280rwhp....something ain't right......there we go......next pull.....320rwhp , more like it =]"

seriously though he knows his shit and that's who tunes my car

"DON'T MAKE EXCUSES.....MAKE POWER"

lol, holler at me next time you see me at bp, i may be out this weekend if my tranny's done

making noise?
Are you sure its not your fuel pump? those make noise, I have 850cc injectors and didnt notice more noise, maybe cuz the engine in itself makes tons of noise, but never heard of inj noise.
its either the fuel pump or the Flow of the bigger turbo that you are not used to yet, is it only when you accelerate?

do not drive you can hydrolock your motor if its getting unsafe amounts of fuel... this happened to my friend but it was because of an o-ring but still...

oh, for sure bro!
thanks for da help, ima try to contact dave at mainstream and try to get it tuned this week...

[bigOdom1]

yeah i wouldn't drive with it untuned anymore than necessary

[jdms-14]

thats whu i just have it sitting in my driveway... it sucks that the guy that helped me with the swap didnt tell me anything about it... oh well, im glad nothing bad happened...

Safc2 is far from a one stop tuning solution, get a rom tune if your on a budget.

What?????

Hydrolocking (hydro=water, by the way) occurs because water gets sucked into the intake, into the cylinders, and everything seizes. Because water does not compress. Water also does not explode (like gasoline).

So unless your injector manages, somehow, to dump a few ounces of gasoline into the cylinder during one cycle (which would be, oh, I don't know, maybe 200x more fuel than it has the physical capacity of flowing), and the spark plug manages to not ignite said fuel before the piston moves all the way up the bore...what you said makes no sense.

You can run The T-28 on stock injectors You can run 14PSI on it without a prob
Im running a T-28 with Stock ECU and injectors @ 14 psi when I had my PFC plugged in my injectors were only reading 60%ish at about 12 psi.?? I forgot by now, but still had enough
so you would be fine at 12PSI

There's more than enough information around to where you can tune the SAFC yourself. Get a decent wideband and an EGT
