Real Cold Air Intakes

[Splash]

I've been reading this awesome US based forum lately - http://www.sr20deforum.com/

I'm amazed at how many bolt on mods they have for the SR20DE over there! :eek: In particular I am interested in the cold air intake setups they have.

I have saved a heap of pics I found on their forums, check them out here (http://splash.ausgamers.com/intakes/)

What do you guys reckon about getting something like this in Australia? I know MikeG has/had one on his car, but he had it imported.

I guess any decent exhaust shop could make up the piping.. Any ideas how much something like that would cost?

Cheers.

yeah pretty easy to make up, a couple bits of mandrel bent pipe and your laughing. Only needs one or two connectors at in the final thing, and then oil catch can the rocker cover, and block the other pipes off. Just a matter or sticking some time into it.

Not sure what costs are associated with the piping. I would think that getting it made (welded) out of pre-made mandrel bends would be cheaper thatn getting one long piece with muliple mandrel bends in it . . but shorley not that much.

i dont know if i would trust having a pod that close to the groud... get a bit of water into it wouldnt ya :confused:

[Sim]

hey thats pretty tuff....but i agree with clay..ur air filter pod would pick up a lotta shit..espcially water...but then yeah u really are ramming that air in..

im guessing u could get these fabricated danny...

the guy at driftking said to me that he wanted to put the battery in the boot..then have a mandrel bent shiny pipe with a pod on the end extending to where the battery used to be...he reckons u could then like pop put the headlight or indicator..(like the drag rotas) and this would help heaps..

i was like.."sweet" but was gonna be pretty exe. so i though bugger that...

i actually like the pod in the engine bay, for show etc..
but if u got more gains from that way i'd like to know..

[nismotoy]

Hey guy's,

I agree with keeping the filter in the enginebay, but just replacing the intake pipe between the afm and the throttle body and leaving the pod behind the battery didn't appeal at all (even well sheilded it's not the ideal thing in my opinion.)
Sim your on the right track - moving the battery to the boot is probably the best way if you can afford to loose the space back there.

Attached is a pic of what my bro and I have managed to do to mine, wasn't the cheapest thing to do, but having access to a sheetmetal workshop definitely has it's advantages!!

I'd be interested to hear your opinions on it :)

Nice shield. I think the gains from putting the pod in the wheel arch arent just from it sucking cold air but also the length of pipe which makes a difference.

[Twells]

hey guys,


I had one simler to the ones in the pictures it was mad from a couple of mandrel bends and the pod sat in the gaurd type thing but I found one problem with this set up when i wanted to clean the filter I had to take the bumper off , No two minute job. I had Rick Shaw replace that with a pipe to the head light and the pod on the end and to be truthful i can not tell the differnce in power


Twells:rockin:

[Ben8OY]

guys i've had this kind of setup for 2 years now...in my old n13 and the n14...its works great and i've had next to no problems with water and crap...cleanings a breeze and response is freakin awesome! oh and it sounds mad too

Forget taking the bar off!! ..thats crazy...what ya do is grab your jack....jack up the front and simply unscrew the clamp holding the pod on the end of your pipeing and drop/pull the pod through the bottom.



When there is a will theres a way!!

[sifuwould]

still... if stuff does get in your filter because of a low pickup you can say goodbye engine if breathes in h2o

Like this,:)

Anyone put a cold air solution to a stock airbox intake on an N14 SSS?


:confused:

[Ben8OY]

I hosed the sucker down with water and didnt have a problem......and besides i dont think waters gunna be getting sucked THAT hard to get enough water alllll the way up the piping and around into the TB..... ive had the filter totally dripping after a huge downpour of rain and ( i didnt have the underguard of plastic covering the filter..oops) it still went great.......

i still recommend it :thumbsup:

[Piz]

As briefly mentioned before I believe, the length of the pipe is going to make a difference :)
In the states they go crazy with those style CAI's.

Yep,
If you rip off the old Nozzle you can put 50mm PVC in place of it and run it wherever you want it to. :thumbsup:

[Tephra]

ive been thinking about CAI for my DET.

firstly why does the length of pipe matter?
second what size diam on the pipe should i get 50mm? 60?

if i scoop from the front does the AFM get bad readings and confused the ECU?

Thanks
Dave.

[AWK666]

I read on a website in the states that if the piping for the CAI is the right length it can have a supercharger effect on the car, dunno how, im not even sure if this evidence is substaitiated. HOWEVER! i personally can tell you that if the piping is too long then the engine has to work harder to suck the air in (get a pice of PVC a metre long and one 10cm long and tell me which one is harder for you to breathe through)

I just realised this supercharger effect that thier talking about!! Its harder to suck the air throught a long peice of pipe, but as the veocity increases the enigine wont have to try as hard as it would normally as the air is going to become smoother flowing!!! Am i thinking on the right lines or am i tripping?

Listen guys, you will not suck up any dirt. As long as you are using a K&N it will be just fine.

The fender liner keeps water away from the filter. Just do not drive thru water that is bumper high. When it rains just use your sense.

The power from it is awesome.

OK, the picture isn't so great but it is there.

Hold on:
This is a great page to show the install:

I understand you guys are worried about hydrolocking the motor but it is not se easy to do.

Hey everyone, im from the www.sr20deforum.com forum. Those are pics of my AEM cai. Like pretty white said, its pretty hard to hydrolock the engine. The fender liner covers it pretty good. And yes, one of the reason for power gains is the resonance that proper intake pipe sizing and length will create. You guys should check out www.se-r.net . There is a ton of good info there. Also check out http://www.nissanperformancemag.com . There is a good article on there written by Mike K. that talks about how a CAI helps.

Yep yep, CAI's kick ass. Place Racing, Hotshot, and AEM make great ones for the SR20.

[Triple S]

Call me stupid ( I don't care I know **** all!!) but what the hell is a pop filter and what does it do. Also do you need one with the inductions talked about in those articles ore can you get away with just the K&N Pod?

Nath

[97 Black SER]

A POP filter is just Jim wolf technologys name for a big K&N airfilter. Heres a pic of onehttp://www.jimwolftechnology.com/toyotapc.jpg

You can get away with just running that filter in the engine compartment, but you will gain much more power by running the full Cold air intake. The colder air is what makes the power.

[Triple S]

K Thanks thought it might be something like that.

Now... WTF is that big flattish silver thing behind that filter???

Also can you refer me to a good thread that tells how to do that full on proper CAI into the area infront of the front wheel guard as I'm interested but couldn't follow the one on SE-R.net

Thanks

Nath

[Tephra]

i had an idea ragarding CAI's

are there any in pipe filters? ie you run piping from your TB intake to a whole in the wheel arch, then u just put a filter halfway along that pipe, well roughly.

then u are sucking cold air in from the outside...

what do u guys think?

d.

[AWK666]

Yeah, but it would be easier and a little less complicated me thinks to just run piping into the Resonator thats already there behind the wheel arch and pike the pipe out of the front bar. Same job, half the holes are already there for you (you night need to do a bit of modding) but i recon that would be easier.

Besides it would be easier to suck in a gob full of air coming straight at you as opposed to trying to lap it up like a dog with its head out the side window.

Why does that guy have 2 filters :confused:

[Triple S]

Sorry what guy and what two filters??

Thats definately not a Nissan. That is a Flap door type MAF used on older Mazdas, Toyotas and BMW's. I am guessing that box is a Toyota Mass Air Sensor. The second filter is probally his crank case breather filter or something. I have a 91 highport motor that uses one. The 93-up lowport SR20's don't use the reed filter.

[AWK666]

NFI dude, its just what ive heard.

[97 Black SER]

Just tried to post a pic of hte POP filter. That isn't a nissan.
