hello guys, well i have done all the research and here are my modifications, i have a y pipe with the pre cats gone. i have a 2 and a 1/4 b pipe from the cat to the factory muffler. i have a racing gear. i also had a shop manufactured cold air intake. All that was done with this was the old intake system was disconnected and a plate added to the snorkel. then the cone filter was added to the plate. the problem is that the battery sits right in front of the filter and blocks it. Is this ok guys or should i change it's location . What would be a good location for the filter at the top of the car and will i see any changes in power if i change. Thanks for everbody's advive. are there any other fairly cheap mods i could do or have i covered all my basics. i have been talked out of reflashing my ecu by puppetmaster.

 

How close is the filter to the battery? Most likely it won't cause any performance loss. You could use some air ducts to help cool air enter your intake though.

BTW: What's wrong with reflashing ECU?

 

What's a racing gear...

 

nothing's wrong with it....but it's not going to "do" anything unless he has alot of engine mods done....the ECU will learn new mods in time anyhow...

I also told him not to bother with the ECU reflash, via PM, when he asked

 

I think you mixed up me and Joel (puppetmaster).

by racing gear, do you mean a short-shifter?

 

as irish stated reflashing the ecu will waste my money. the reacing gear, i will tell you the way they told me. a few months ago while driving a car struck the front passenger side of my maxima. the force disconnected the drive wheel from the fwd transmission manuel. when the shop were fixing it they said that the gears that the transmission turns on my car were actually aftermarket racing gears and i would have to reorder these ones if i wanted it to drive the same. i got the car with six thousand miles on it so i guess the prevous owner added this mod. BTW what do you guys think about the addition of a racing clutch to my maxima, i heard it has a hell of a lot more pull and a stronger grabbing traction than the factory clutch

 

a number of us went into the effort of convincing him not to do the reflash, but sure.

 

I just wanted to find out what's the deal with ECU reflash. ya, in this case it makes no sense to do that.

 

How many times has a shop you...

Ask them what the ratios are.. and we'll tell you how racey they are.


You need to move on to more advanced performance besides I/Y..

Get headers or stick with the y-pipe.... Some have said they're going to get a dyno comparing the 2 (Y vs H) but no one has just yet


Remove the VIAS rod.. DO NOT ASK ME HOW because it's in the stickies.

Spend some quality time in the F/I forums and AM...
Try the dyno forum for some tuning tips etc.

Start working on your car on your own and stop letting shops own yo so badly.

 

nmexmax can you at least tell me what the vias rod is so i know what to remove, thanks

 

Did you even attempt to read about VIAS the FAQs and How-Tos? Do it and you'll know what it is and how to do it.


Btw, I have to call on the race gear thing until we see some description and pictures of what they are.

 

No, we had an ECU reflash discussion here:

There are none for 00-01s. At least, none that really work.

 

If your intake looks like this:



It is not a CAI, but a short ram or WAI, which many people here have (JWT/Stillen, Weapon-R, Berk and Frankencar make it). It is fine for airflow and you will probably not gain that much by relocating the filter or the battery. If ya really wanna do something to it, the only change you could make it so make an extra tube that would bring the filter down below the battery right by the fender wall and drill a hole in the plastic fender cover. This is how the Place Racing CAI works.

 

this is exactly how mine looks, so i will leave it like this, hey puppetmaster i already read the stickies on the vias valve system. According to the stickies the valve should be totally removed. if i totally remove the valve wouldn't i lose low end torque due to tomuch airflow at low rpms. are their anymore stickies with better directions.

 

You will lose low end and gain high end w/ removiong the VIAS rod. Pay to play.


.....It's not an amateur mod, and judging by most of your post, that would rule you out as a candidate for performing it on your own.

 

Post links to the stickies you have read and so we'll know if there are more to supplement what you've already read.

 

don't remove the VIAS unless you're pushing more power (FI), IMO.....

 

ok i wont what about resetting my advanced timing to seventeen is that recommended.

 

Yes. That will produce a noticable difference on your car and costs only 80-100 bucks at a dealership.

 

ya, that's a good idea. I was very suspicious at first, after all, it puts more stress on your engine... But after seeing people running over 10psi of boost and making like 500whp on stock internals for over a year, and actually using all that power, I decided that advancing timing by just 2 degrees should not cause any problems.

What I'd recommend though is to first clean your engine with Auto-rx: auto-rx.com
That's what I'm doing right now. I'm ganna advance my timing as soon as i'm done with ARX.

 

What is that black duct with the red sticker on it above the radiator? thanks

 

it's what's left from stock airbox.

 

wow, I've owned my 02 for about 4 months now and it never had that part. is it worth picking one up? ****!

 

It only assists in guiding air in to the stock airbox. I wouldn't worry about it, though I suppose you are directly guiding a tiny amount of cold air towards the short ram. Course, maybe it was left on to keep from losing it...

 

Don't worry about it. If you want to pick up a couple of free ponies, do the gab.
