Don't forget the RSM throttle body parts too. All this stuff tends to help the high end more than low end. Another suggestion - at 82k or anywhere up there, new plugs and plug wires (DO NOT fool with anything other than replacing with the exact same stock plugs - anything else has shown to cause problems) will probably help. Don't be too lulled by the 100k on the plugs. Be realistic, they probably serve fine up to 100k, but I would be surprised if they perform at 100% up to 100k before starting to slide.
Also - clean the throttle body. At high milage with this never being done (or even once), you are losing power for sure.
In short, before looking to modify, take care of the maintenance first. It can make a difference. And yeah, a simple K&N filter and box mod can add a tad bit of power right away. You want more - then look to Corsa and an RSM throttle body.
#249 of 267 A few statements and questions

JRS -- how much louder is the Corsa system during everyday driving than bone stock? Awesome sub-15s..
Also, I hear a lot about using the 2nd gear position.. On my Classic (managed to buy a 1998 with 26,400 on the clock), using second firms up the shift quite a bit. It seems to cut the shift time in about half, and if you forgot you placed the shifter into 2nd, it will surprise you. I actually can hear my serpentine belt squeak during the abrupt RPM change.
I second the want to find someone who can change the PROM variables on these OBD-II cars.. moving the redline up a bit would be good (in 2nd, the Classic shifts around 6100, just before the hash marks.. but the engine doesn't feel anywhere near valve float).. it just dosen't feel out of steam at 6000. I'd buy V-rated tires if I could increase the top speed variable.. it pulls strong at 110, and the cutoff is quite abrupt.
On an extremely minor note.. does anyone else's PCV valve buzz like crazy? I've replaced with a third-party and an AC.. both rattle audibly at idle.

I have the Corsa too. It sounds awesome. On the highway, it's stock quiet. Around town, it's not bad at all. At WOT it sounds great. I was very wimpy about getting it, fearing it would be too loud. I am so happy I got the Corsa. Check out my post on the modification area. Let me know if you want pictures and info on how to modify the Corsa STS system for the classic Aurora.

I second Greg's observations. His are more relevant, though, as he has a Classic. On my 2nd gen car the exhaust is stock-quiet most all of the time unless you get on the throttle a bit. If you are accelerating you'll notice a little more noise. If you gun it, it will be noticable but not loud. Louder than stock but to me it is not obnoxious. Cruising is quiet as stock, possibly quieter.

I expect I'll wait to get some more use out of the stock system, but I like what I'm hearing about how the straight-through path can open things up. I wouldn't mind a little more growl -- the sound is for sure part of the feel of a car. I think even a bit more of a roar at WOT 5k+rpm would be welcome. Garnes -- did you say you live around the Indianapolis area? I'm camped out on the west side.
I haven't managed to secure a profile, etc, anywhere, but I do have some pictures I took the day after I drove it home if anyone cares
It had the spoiler when I bought it -- I am impressed that a lit one was made for it. I read that it was not a factory option, but I have to assume it was dealer-installed, because I can't imagine the older couple the car belonged to jumped through hoops to get it.. I haven't seen another one to date.
Maybe a somewhat off-topic post.. oh well.

I saw a similar (maybe the same) spoiler on a Classic in Johnson City, TN, last month. It was at a repair garage that was closed, so I didn't get to ask anyone about it. How does the light operate? Brake light? Tail light? Both?

It's brake only, I believe tied to the high-mount light (which is also in place).
#255 of 267 95 Aurora electrical Issue? need help
Aug 21, 2005 (6:18 pm)
I have taken the car to the dealer and it sat there for two weeks. They ran a complete diagnostics and couldn't find a problem or they were unable to recreate the problem. The problem is that when driving the car it just turns off. It happens on and off sometimes when I'm at a stop sign or even while on the road traveling. When I turn ignition its as if the car is dead, no sound nothing. Then I try again and it kicks in like its attempting to start after 3 times or more it kicks in and starts up. Can anyone tell me if this might be a fuel pump issue or electrical.

Sounds silly, but.. battery terminals? An intermittent failure of everything in the car makes this the first thing I'd check.
The fuel pump isn't necessary to crank the engine (if the fuel pump's out, the car should crank until the batt is dead, just won't start).. Nor, if it dies when running, can we blame the starter. Lock cylinder is a possibility.. it controls lots of stuff.
Will the horn work when it's "dead?" Easiest thing to check that will always work. No computer, no logic, no ignition key position.. just a switch, relay, and battery. If the horn's dead, think battery, terminals, wiring, fusible links, fuses.. in extreme cases a short somewhere.. but enough shorted current to stop the car dead in its tracks would generate smoke somewhere.
