I have a 2000 A4 Vette, and was considering installing a set of Long Tubes W/Cats, a LS6 Intake and maybe a U/D Pulley.
What should I expect from this upgrade, and is it worth the money?

I would wait until you swap cams for the UD pulley unless you get a good deal on a used one.

ALSO,,,,
I just read that the 2000 Corvette came with a 78mm TB and #26 injectors.
Is this a factor when looking at power?
Should I look for a 2001 Later 85mm TB and #28 injectors when making the changes?

Without a doubt your goanna feel the new power from the money you put in.
Id go for it..Your choices are pretty much the best horsepower for the buck.
Dont forget a tune if you arent planning on doing more anytime soon!

def the LTs and intake....just sayin i have heard mixed reviews on the underdrive pulley, some ppl like them and others dont, so do more research into that one, but all of these bolt ons will DEF give you more power

If you're planning on doing more later on and for the added benefits already, might as well go 92 or 102mm intake and 32-40# injectors. Better than switching now and having to switch again later

The headers and intake are definately good mods. A lot of mixed feelings on UD pulleys, do more research on it. Upgrading your TB and injectors are pointless at this point with only headers and intake mods. They will not net you any gain in power. The stock fuel system can support close to 500whp. And btw, all C5 Corvettes ('97-'04 including Z06) all came with 75mm throttle bodies. 2001 and later C5 Corvette's came with 85mm mass air meters, but the throttle bodies were all the same.

There is a lot to gain with those parts and a decent tune...the injectors will work for what you got now.

first, do you have a bigger stall?


but yes those mods are worth it. get a tune too. get LTs though. nothing else.

Here's a video of me racing my brother before headers, ls6 intake, and mail order tune, and then after.
