This is still a work in progress, but it works 4 now.
I moved my battery to the drivers side, and ran a few cheap elbows from autozone. In the process of making a custom air box to fit on the throttle body, and running a tube to pull air from the front of the truck. Got to get rid of those ugly pacesetter headers to!

 

[TheOregonFront]

cool, but why are you goin to take the headers out? besides the CAI thats the best performance mod you can do.

 

[nastynissan]

Didn't take them out. I just want something that looks better. Probably some stainless Megan headers. I'm taking all the brackets off and painting them a metallic silver, so that stainless will look a lot better than flaking paint.

 

[PeeWee]

Any noticeable gains from that cai setup? I have been trying to figure out something to do about mine.

your goofy man, of course your going to get some gainage from an aftermarket induction system

not necessarily

X2 I know plenty of people with CAI's who noticed nothing but a change in sound. None of these are frontiers but nevertheless, CAI's don't necessarily always work.

 

[nastynissan]

Yeah, you notice some change soon as you hit the pedal. It's a small change though. It's not like you put a turbo on. With the intake and exhaust the sound changes more than the hp, but any gain is better than no gain. Nomatter how small.

That really depends on the vehicle. I know people who have put on custom made CAI's and they actually lost power and torque. Like someone said in another reply, the biggest change is that in sound. A CAI mated to a header (in the 4cyl) and better flowing exhaust could show some performance gains when you are dogging it and in normal driving you could see an extra mpg or 2. But you have to look at the cost if you are trying to increase mileage and figure out how long you will need to keep the truck to make your money back.

I was thinking of doing the same setup, smaller filter though. I have a Pacesetter header. When I get back to the states, I'm getting a stainless header with a 4-2-1 instead of this 4-1 that the Pacesetter has. The KA responds better to the 4-2-1 setup. I am considering the intake off a 240 as well. Then everything will match up well. If you get another header, go with the 4-2-1 design. Looks nice, I don't think you're done though. Take care.

[prior8t2000]

Yup, I am still looking for a good Header.
I currently have a Pieceofshi!!er on as of now.
I did help with some power gains but, not a hole lot...
...
Tanks, if anyone can point me in the right spot or location for a new one.

 

[1fstmax]

good set up! what are the sizes of the couplers you used?

 

[upcominZ]

That filter is way too big. Talk about overkill. I don't think there are too many gains on the power side. Mostly sound. The displacement is just too small to notice the gains of sort ram intake(thats not CAI, not that either make a noticeable difference). On a dyno, you will maybe gain 2-3whp with that intake. I think you would have noticed the same amount of gains if you would have replaced the stock filter with a KnN filter.

An aluminum underdrive pulley is a really nice mod, quick, easy, and proven. If you are DOHC, a cam swap from a ka24de from the s13 will help. they're plentiful in the junkyards.

Headers may help, but don't remove the cats, the gain in HP won't make up for the loss in TQ experienced from the loss of back pressure. You need the cats on NA engines for the scavenging effect of the exhaust flow.

 

[nastynissan]

sorry I've been a little busy. Those are 3 inch couplers. They don't fit perfectaly on the throttle body, but they will stretch a little. I'm still waiting on a friend to make me a custom air box.

i dont think that filter is too big at all. the more air you suck in the better, do you even know what your talking about on the cats? jesus man. the factory cats just plug your exhaust up.

If you don't know what exhaust scavenging is, then you really don't know what you are talking about. If you strait pipe your exhaust and add on a high flowing exhaust, then you greatly reduce your back pressure and will lose tq. If you use flowmasters or what ever baffled mufflers, then you won't lose as much backpressure b/c they are really not that high flowing. If you decide to remove the cats, then I would add in an xpipe or Hpipe.

And, yes that filter is way too big. I would love to see that filter and short ram compared to just a k&n drop in on the dyno. I bet there will be no difference. I guess you have to factor in the chrome factor.

I had a drop in K&N filter, and it worked ok. I made this intake because I didn't like the way the Weapon R ran across the motor. It just gets to hot. With a smaller filter the motor would bog down through first and second gear. So I put a bigger filter on, and that solved the problem! So I guess the filter isn't to big! As far as the cats go, I have to agree. I learned the hard way. You need some back pressure, or it feels like you are pulling a big load all the time.

I also learned the back pressure thing the hard way. My other car is a 300zx TwinTurbo. Back when it was NA, I was going the whole NA way, headers, pulley, intake, ecu, and exhaust. Well, I did the test pipes and instantly it felt weaker in the lower rpms, and i really couldn't fell any extra pull on the top end. Later I learned NA engines need back pressure for lower rmp tq. The new Twinturbo engine is fine with no cats b/c the exhaust turbine provides all the needed back pressure.

I guess your right about the filter being needed that big, it did fix you bogging problem. It does look really nice, and, I not trying to be hard on you. To each their own.

But, performance wise, just a drop in would be suffice. But, you get an A+ for the cool factor. :goodjob:

 

[BigMack00]

What did you do with the sensor that plugs into the end of the stock intake right before the box?

 

[ryanschillinger]

You can't run an h or x-pipe on the truck, it's a single exhaust coming off a 4 cylinder... And damn OregonFront, relax man! You might know more than everyone else, but don't gotta act like it. Haha
Anyway...
I removed the cat from my old Nissan, expecting a power gain, but lost bottom end big time, ended up putting a 2 1/4" cat from a Mustang GT on, followed by 2 1/4" pipe and a Mac Flowpath muffler. THAT was a killer setup on an otherwise stock truck with a K&N drop-in filter. Some vehicles react differently to mods than others might, so if you really wanna find out, try it. If you don't like it, change it to something different. I tried a few different exhaust setups until I found the one I was most pleased with. The 2 1/4" piping (with cat) and that Flowpath muffler was my favorite by far.
