Intake.

[vang240sx]

I read in the installs part of 240sx.org and saw "Marks custom s14 short intake". I was wondering if a short intake would be better then an intake like injen.

Well, the injen is a short intake to begin with. You pay extra for the Cold Air Extension.

When looking into this though, here are several thing to think about.

Does it flood where you live? If so, then a CAI may not be best for you.

My car only had a Short Ram Intake from AEM, and it was perfect for me. A lot has to do with your plans for the car. Are you looking to do a lot to it? Or is this simply a little boost to the cars power?

If more modifications are to come, the I would go with the CAI as long as you don't have to worry about flooding often.

About the Intake and Cold Air Intakes... I have been told from the Nissan Dealership from where I am at that there have been some folks coming in with there 240's hopped up and and the ones especially with the Intake or CAI hvae been coming more and more frequently about some engine trouble and/or problems. I was wondering is it common and is it a part of the side effect of having a cold air intake/or plain intake?

some CAI users have had problems with the motor running a little rich due to the extra airflow being overcompensated by the ECU and too much fuel being added. This will set off a code. As will not enough fuel being added.

Personally, I have not ever had this problem.

If you dont have the CAI extension, can this problem still occur. There wouldnt be too much air being put in if I didnt get the CAI extension right, because I was planning on getting the AEM.

How would you correct the rich fuel problem? An adjustable fuel pressure regulator?

[Aries]

usually, you just reset the ECU, and it will recalibrate on next start up.An adjustable FPR will also fix the problem though

i think vang's talking about this intake: http://www.240sx.org/links/ins...x.htmcompared to this, the short injen is a monster

I doubt the CAI is the actual cause of the problem. The MAF's, particularly in the S13's are quite sensitive to turbulence. I've had a CAI in both an S13 and my S14 and neither ran rich or threw codes. Hell, my turbo doesn't even throw a code for that. My EGR is bypassed so that trips the code...

As far as short or long intakes, long intakes tend to have a resonance effect and may give you a slight hump of power somewhere down in the midrange.

And as far as wet areas, consider where the filter sits. It is fairly high off the ground. And consider the top is typically just under the sheetmetal. You have to pretty much submerge the filter (or at least really close)in the water to start sucking up water (like a straw) into the intake. Small droplets of water won't do much, and may actually cool down the intake charge a bit. And as high as the opening is, you'll have to drive through water that is higher than your rocker panels. In other words, you'll probably have water coming into your interior before it gets sucked into your motor. If the water is deep, just avoid it...

Personally INJUN is the way to go. I just bought mine and it gave me good HP gains and Torque. I havent noticed a change in gas mileage. And unless you drive into a lake you wont have to worry about sucking water into the manifold. A good buy and a Great look.

You mount it at a high point on the intake and if water, snow, or whatever gets in the filter it bypasses the filter so your engine doesn't suck in stuff.

i had an injen a while back...i got rid of it for a custom cause i didnt like the way the pipe runs over the radiator in my s13. i just moved the battery, MAFS and extended a few tubes so i could have the intake come right down from the throttle body and into some cooler air. But it really doesn't flood around D.C. much.
