Ho lucky are you guys that they sell CAI kits in the States!!
I'm from SA and Nissan accesories are few and far between.
Well, I am from Greece and over here it may be even worse than where you live!!
The USA guys complain about the luck of SR20 parts in the States (as compared with Japan), the UK guys complain about the lack o fparts in UK (as compared with the States)0, we compalin... etc., etc.

Anyways, I'm going to manufacture my own CAI. Need som e help though. Can I leave the standard piping between the TB and MAF?
Of course you can. For starters, this is what almost everyone with a WAI (Warm Air Intake, aftermarket cone filter, Fitler Pod, whatever you want to call it) does.

Will it be better to:
Remove the filter box, replace it with a Cone and heat shield and then have a cold air pipe that runs through to a vent in the bumper?
or,
Have a cold air pipe straight from the MAF to a cone filter located behind the bumper/grill?
Any assistance appreciated!
Between the two, the 2nd option is certainly better. Your 1st option is only a cone filter with heatshield (good enough) and some cold-air feeder to it. It work OK but 50% or more of the CAI gians come from the air "tuning" effect that is created by the CAI piping from the wheel-weell (in our cars this is the preferred position) and 50% or less from the colder air.
If you can go the full CAI way.

ps: Who can help me to have my cars pic hosted so I can reveal it to the world? I think you guys will like the SA version SR20 pulsar...
I suggets you may try to be a bit more patient... You ask a question on January 2 when most of us are still recovering from the festivities of New Years eve!
20 minutes later you wonder if anyone is going to answer your question... This is rather hasty, don't you think???? Not to mention the fact that in the US where 90% of the forum lives it is was anywher from 1 in teh morning to 3 int he morning of January 1.
Thanks Chris!! Didn't really know there were Nissans in Greece but there you go. Send me some pics of your ride if you want. ronnieb@discovery.co.za
I've been sorted. you can view my pics under the topic "My SR20DE Sabre from SA" on this forum.
Pls give me more exact info onhow to set up a proper CAI for my car. Where to palce the filter, where to run the tubing etc. I'm struggling a bit as there's not much space and I don't want to screw it up...
You'll get the idea. There is only one "correct" way given the engine bay space in our cars (your is a N14/B13 as well judging from your pictures) and it places the air filter in the wheel well, behind the left fog light on the bumber).
I dunno, although I have no hard proof my car seems to feel better with the AEM, and I had a Hotshot about a month before I switched.
My AEM CAI felt better too...
This above dyno sheet is from late 2002.
At that time I had pullies, no p/s, lightened flywheel, HS Gen5 header, 2 1/4" cat-back exhaust, S3 cams, stock ECU.
Vs.
This from our last Dyno day back in Sept, 2003
Same mods as before except, AEM CAI and JWT ECU with S3/4 cam program.
Now on the surface the numbers are close. However, with the ECU program, I should have peaked a couple of HP higher and had a bit more area under the curve.
When I looked at my Dyno sheet I was like "WTF, NO HP gain?"
After talking with a couple of the SoCal SERCA guys (Martin G, Naji Dahi and lastly, Mike Kojima all of whom had been present), I had learned that the AEM CAI was good for SRs with NO mods. And the Place Racing/HotShot CAIs were good for SRs with everything.
Subculture, was the orange line which peaked at 138.7hp the stock setup? Did you dyno it on the same day and same place? For all those mods you have, you only gained slightly over 10hp.
When I replaced my PR cai with the AEM, I definitely felt a gain and I have all the common boltons. But maybe the the difference varies between the highport and lowport or even between models of the same year. Also could it be the jwt ecu running richer which causes the drop in power. I've seen a couple of times that the jwt ecu makes less horsepower from independent dynos.
And does the dyno reflect the correction factors for atmospheric conditions? It shows obviously that the conditions shown in the first dyno is favorable. I have experienced running on different days at the same track resulting in a consistent deviation of a few tenths of a second. Also the alignment on the rollers might cause a deviation also.
I dunno, but the AEM feels so much better than the 3" PR on my 99se-l. And AEM is the only one who don't just built their products to fit.

No, that line shows, where the $tillen header power began to fall off as compared to the peak HP gain from the HS.

Same place, R&D Dyno Service, but not on the same day. However, I always made sure I had a fresh tune up/wheel alignment etc.
Quote:

No, all those mods put me slightly over 30HP over stock.
The HS gained 11HP over the $tillen.

NEVER trust the butt-dyno!
That's why there's Dyno testing.

Maybe, but I doubt it.

The JWT ECU leans the fuel map out a bit as the OEM fuel map tends to be a bit rich of stoich.
BTW, have you really seen JWT ECU lose HP compared to an OEM ECU?
And if so, did the car that was using the JWT ECU have the base timing set at 15* BTDC?
Quote:

Yes.
And I make sure that my engine is at proper operating temp, before I make a HP pull.
Quote:

I always run OEM alignment settings whenever I Dyno.

That's because the AEM CAI has a smaller diameter piping and a shorter overall length. This enhances bottom end responce.
However, the downside is, you'll give up some top-end.

Actually, Justin Choi helped Place Racing design their CAI.
So it wasn't just a case of Place Racing just bending up some piping and selling them.

This is news to me. How did Justin Choi help Place Racing design it? Where did you find this info? I would like to read it as I still have my PR cai lying around and I might switch back to the PR once I add a few more high flow mods to the engine. I've always trusted AEM for the reason that they actually "research" and develop their products unlike most other aftermarket companies who does no research at all.

This was info that was mentioned awhile back in the SE-R mailing list.
Can anyone please provide me with the pipe lenths on the AEM or PR CAI? I need to make my own as we're not lucky enough to get them in kit form over here.
