Default What C5 mods should I consider first

I know most of you guys know me as a C3 guy. I have been hard core C3 on those other forums and rarely ventured out of my comfort zone. It was a little over 3 years ago we surprised my wife with a 2000 C5 for Xmas when she made the mistake of saying wheres mine? She doesn't know how to drive a stick. Well it is bone stock right now, but what mods should I consider first?

Get a cold air intake, long tube headers and then have it dyno tuned - that thing will SCREEEEEM.

Those C5's are really good cars, don't you think? Fast, comfortable, reliable, good gas mileage and you can get them pretty cheap.

I thought it already had cold air intake??? Whats that box in front of the radiator? To tell you the truth, I haven't looked at it very close.

Just wondering.....won't you have to mess with the ECM settings to change things?

It does but you can open it up a lot more. There are a couple of different ways you can go. You can get a bolt on like a Halltech or some of the others like that that draw air from the engine compartment through a larger fillament, or you can get something like a Vararam which draws air through your front brake cooling vents, through a filter and then up to your throttle body. Then there is the Callaway that draws air from a slight modification you can make to your fan shroud. The Callaway is what I decided on after quite a bit of research - but they are expensive.

Anyway, if you start researching this topic more you will encounter more opinions than you want to hear, you know what they say about opinions.....

No, you drive the car 30-40 miles and the computer relearns following the change in air volume registered at the sensors in the MAF at the throttle body.

Isn't there a paper someone wrote about modding the current C5 airbox for cold air? I'll try to find it.

A cam swap would really wake it up, replace the timing chain and valve springs at the same time... however it's a lot more work than doing it on the old SB...

First mods should be exhaust and a handheld programmer, I got the Predator and really like it. You already got nice rims, lower it a lil
