pretty much if you run boost without a fmic untuned then later down the road there will be air/fuel problems, and itll start to run sloppy. no fmic but tuned, while be a little better but you can only run minimal boost. fmic + tune = sex =)

this is what everyone is telling you in simpler words, have fun ;D

the motor is going to need a tune if you boost it, no matter if the injectors are stock or not

it does not need an intercooler. the intake charge will be warm but def not "exhaust temps". my air charge runs about 65*c on a fully warmed up motor, im guessing his would run around 70-75*c without one. with the warmer air charge you would need to run higher boost to make the same power fyi

the motor is not going to overheat, but a dual core radiator might be a wise upgrade come summer time

Having no intercooler means you need a richer A/R to compesate for heat and/or less potential hp. Extra fuel and no intercooler means less effeciency in this case.

he will do that later on, he does not want to do everything at once. why would you need a tune when none of your air/fuel settings are changed? the car should run fine without a tune.
Not true. Untuned = run like s**t AND f**k s**t up.

Boost is NOT as simple as bolting a turbo up to the head. It takes money, knowledge and a COMPLETE kit to ensure everything is functioning.

Its one thing to skimp on JDM parts or something and buy some knockoffs, but boost is NOT one of the things that I'd skimp out on.

Might as well tell your friend to just wait til he has everything together at once.

This is the part that I don't get. How do you figure the air/fuel settings haven't changed? Do you realize that a turbocharger literally shoves huge amounts of air into your motor? Obviously you are going to need to throw more fuel in the mix.

where does this "extra heat" argument keep coming from??? the intake charge is not going to be hot compared to the typical temps. it will probably be a 5-10 degrees warmer than the factory intake would make it, which also means the air charge will be LESS DENSE thus requiring less fuel for a stoich ratio... there would be no need to run any more rich than a typical boost setup runs

where at in bama are you?

we need more people from here.

but..sorry i have no input in the OPs question.

Go back to blahmans post, I think he is the only one that was hung up on no FMIC= overheating...which again is not true

allright,
compressed air= hot air, well warmer than normal, that also depends on what turbo and the efficiency range you are in on that particular turbo. i wouldn't worry about that on this setup.
intercooler on 5-6psi ins't necessary, but we all know boost=crack. so he will want to turn it up, thats where its good to have an intercooler, because as covered before, more pressure=hotter air.
5-6psi will just give him a taste of what it can do.


Your kidding right??

Well since you appear to want to be an e-smartass. The intercooler, like I said, cools the intake charge which will help improve the combustion efficiency(ambient air). The FMIC simply raises the det. threshhold so you can throw more boost at the motor....that's it. Running a car with no intercooler does not let air into the throttle body at exhaust temps...that is silly....but since you have "first hand experience" I guess you already know that.
Intake temps and engine temps are different. What your saying almost sounds as though you are implying that a non intercooled cars IAT would be the same as its ET.

radiator...
he may be an e-smartass, but you are an e-dumbass.
IAT has nothing to do with combustion efficiency, hot air can burn fully burn fuel, so can cold air, you can get a 14.7AFR in both(which is perfect burn). has nothing to do with det. threshhold, as long as you are within a rich to stoich AFR. now hot air can cause det. but you would'nt contoll it by cooling the air. you would retard the timing. which is what factory turbo cars do with a know sensor.

so i would recomend to get an IC, even a used dsm sidemount is better than nothing, but you can run it without, as long as you take proper precautions.( timing)

are you shitting me???? what is it that you think a turbo does exactly?
