Yeah that never happened sorry about that. Ended up sitting down to dinner to find out I got the wrong order. I work till midnight so I will see if it dims or not when I leave.

Still no luck on seeing if it dims. All the hi beams are coming my way and I'm headed the right way down this road. Don't even see it as an option in the 98 brochure. Electrochromic is only listed as Mirror, inside rear view. Outside mirrors are heated.



While I was debating on if I want to cut up the pre 99 air box some more, I took the 99 and up air box apart for pics then cleaned it up(in that order).

All the pieces of the jigsaw puzzle laid out.

Here is where it sucks air from behind the drivers headlight. Pre 99 sucks air that passes the headlight and traveled into the fender well.

This area is the foyer, The ECU hangs out in here.

Once it leaves there it heads to the filter media.
Hole on the left is what the filer breathes out of on a pre 99 air box. Right is 99 and up.

^ I swore I submitted this last night but didn't. Looking at the box it has larger holes and the air comes from the top instead of the bottom. This makes water have to defy gravity to get into the filter. The pre 99 air box gets wet inside the "Foyer" in a drive thru car wash or even light rain situation. ECU sits up and air goes under it where new stile ECU chills on the bottom and air passes over it slightly. The tubes are almost connected but leave slight space to give ECU air and resonate inside the "Foyer" of the air box.

 

Wow, that pre 99 looks really restrictive in that last pic. I can't say I've ever paid close attention to the setup on mine. I only had it 80% disassembled when I took the ECU out in July.

 

Yeah when I removed that snorkel it didn't make the hole that much larger. If you notice the snorkel bottle necks in the middle. Going to cut a few more holes in the box with the dremel and take pics. If I can get a drill I could do the overflow conversion. I might test fit mine behind the air box. I kinda remember room there to do that. I still have a universal overflow bottle for my Top Mount Intercooler Sprayer project that's going nowhere on the Subaru. If it fits I can extend the hose to the bottle and call it a day. Might even dremel the Impala throttle body to fit my linkage. LG8 has same linkage as the LA1 but smaller throttle body.

Sorry about that had some computer issues. Just upgraded to Windows Se7en and a new hard drive. Luckily I was able to salvage the pics and files from my other hard drive.


I did get to test fit the LG8/LA1 airbox and nope the oem and aftermarket overflow tank can't be moved behind it. Back to the original mission, cutting the pre 99 box up. Also just a random thing, the L82 air box bolts to frame where the LG8/LA1 just pops in and out with rubber tabs.

Pics start here.

Here is the box with ECU removed. You can see the somewhat lip that holds water. In the LG8 box, the air enters the top half of the box. Hope nobody plans on fording a river in their W body granted I seen 26 inch wheels kinda fit the Century with "some modification" on YouTube.

Here is the opening where I removed that bottle neck snorkel from my 98 air box flowchart thread. I could have placed the snorkel back to show where it was in relation but it's a day late and a dollar short now.

This next one is the hole where the box breathes from the fender just above the tire(the next bottleneck). The Regal guys run their CAI filters this way. Grand Am guys aren't as lucky cause they have a fender brace here.

Here is the new big gaping hole in the air box. I went back in later and smoothed the edges out some. The angle that wall is at made cutting a traditional square hole almost impossible.

Since I was there, I went and cleaned the throttle up some. Started to rain so I didn't do the LA1 throttle body swap.
http://i90.photobucket.com/albums/k2...6/be4a39e8.jpg

Still kinda early to say but it didn't make a drastic change. Car is still learning but mpg wise I say it helped some. Air box didn't get magically louder or more aggressive sounding(cause of the bottleneck in the fender). Once the winter breaks I might just go with the ZZP air box with a IAT extension and ditch the LG8 factory one. Will make a for sale thread once the ZZP is installed. Might even make one for the Canadian Gauge Cluster too.

 

It sucks that you can't use the LG8 air box. Do you know if there's any way to gut it? I'd like to try to make mine a little more free flowing, but I don't have the space and time to take a look at it for a while. Exams start next week. haha.

What's the ZZP air box like? Any improvement over stock?

 

I'm convinced the box is way better and linear for airflow than the L82 I wasn't doing to to much to it. My last 2 bottlenecks is the opening of the air box into fender and when the 90 degree bend into the maf. I was told by many do not gut the honeycomb on the maf.

Making this hole larger on right.

The LA1 throttle body is a direct swap for your car. I have to cut my factory linkage to get the TB plate to fit.

ZZP is here. http://shop.zzperformance.com/store/...ir-Intake.aspx It has an air box on it and a spot for the ecu. I remember seeing one of these a few years ago on a 03 impala and it sounds nice. For most my cars I did both short ram and cold air intakes. Short ram was the most noticeable gains but once the engine bay gets hot from sitting in traffic you lost those gains. My Subaru loved the sort ram but it the intercooler couldn't help it much cause it also got heat soaked from sitting on top of the engine in traffic. CAI had more power but the placement of the vents in the scoop to cool the turbo leaked water down the intake and soaked the filter when it rained hard enough. Turn the car on and half a block later CEL light for wet maf sensor. Reason I am going for this setup cause it keeps filter in the engine bay for sort ram and air box for heat soak. Still have to drill holes for the overflow unless I can hack that metal on the tower from another century.

 

That ZZP box looks pretty cool. I'd like to do a short ram or full cold air intake on my car, but i doubt i'll ever get around to it, if I still have the car.

 

This car isn't going anywhere. Once the Subaru gets running again this will be the mpg car. Even debating on the MPG cam instal way down the road. You could Make a short ram if you want, you just need to fabricate a heat shield for it from the radiator. Regals poke the filter just outside of the fender by removing the drivers tire splash guard. I have way too much fun with puddles here. Subaru has short ram cause of the CAI check engine lights and the intercooler helps cool the intake air.

 

Haha yeah, I'm the same way with puddles. If I don't have a new car next summer, I might try to make a short ram. The only thing I'm afraid of is figuring out what to do with the PCM. I feel like if I leave it out in the open, it'll corrode, and open a whole new realm of problems.

 

Wrap it tight in plastic & duct tape. You aren't going to drive onto a military installation anytime soon right, LOL? The ECU in the pre 99 might as well be exposed. There were salt/water stains under the ECU when I took it out of the AIRBOX.

 

Well, that gives me a little more confidence. haha. I remember looking at a bracket for the regal that moves is directly under the intake, for CAI applications. I can't seem to find it now..
