I've just purchased my first vette. It's a 2000 verted auto. I already added corsa touring exhaust and mti ram air. I was a little disappointed with the sound of the touring and I'm looking for something to increase it. What are my options? TPIS long headers? Also, what are the next mods I should add? I've been told that a t-converter is the best possible mod for an auto. I think I'm going to add a 2600 Vig. Does that sound about right if I'm not going to do cams and heads right now? And last, can I run the 1/4 in the high 11's if I add every possible bolt-on, or must I do cam and heads? If anyone has a plan I can follow I would really appericiate hearing it. I know it's a lot, so thanks for your time. A new member, Eric. :cheers:

 

I am new also, and just beginning to put mods on my 2001. I just spent hours at my dealership today (LONG STORY), and talked to the corvette mechanic there. He has done tons of Corvette mods.

We discussed Torque Converters, rearends, NOS, everything.

He told me, to do the rear end differential AND torque converter at the same time. Basically, you take out the tranny to change the rearend, so you might as well put in a converter at the same time and save a boat load of labor. Also, you then need a Hypertech, or some programmer to reprogram the ECM for the new rearend and such. I'm stuck there, because Hypertech doesn't have a programmer for the 2001, only the 2000 and older. I've TTS has poor customer service, and I just don't know enough about the LSI Edit to talk intelligently about it.

So, I do plan on either a 3.42 or 3.15 rearend and a P.I. vigilante 2600. The mechanic told me about 12 hours labor for both, including the reprogram. I think I can work that a little better though even though they are giving me a cut on the hourly rate. The mechanic has mostly done Yank rearends, but my service manager told me to do a 2600 stall and not a Yank 3000. And he is the one who is going to continue to honor my warranty with all my mods, including NOS, so I follow his advice.

You'll have to do an awful lot to get into the 11's though. Your biggest problem will be traction, and unfortunately no one make a drag radial for an 18 inch wheel. There is a big email campaign right now with Nitto to try to encourage them to make a drag radial for the 18 inch wheel. That post is here:

So, good luck on your mods.

with bolt ons and no internal motor work, 11's should be easy :yesnod: If nothing else, nitrous should bring you there :D
If you want a louder exhaust note, there are a few cat-back exhaust systems that will be nice and loud, Borla XR-1, SLP Loudmouth, PRT's should be louder too. Headers will make your car louder too.
Best advice I could give you is to find a local tuner and work with him/her.

 

Kurt is your 2001 a 2.73? Because mine is a 3.15 and I'm told the vig. 2600 to2800 is just right. What do you think?

Good luck with the labor. Eric

Look at my mods & times. No NOS...all bolt ons and want the LS6 intake to finish it off. If I add the converter I pick up .5-.6 seconds....that puts me in the 12 flat, high 11's. And that is with 3.15 gears! Put the 3.42's and you are surley there. Tires are a must & I have a set of spare front 17" coming to put Nitto or BFG drag radials on for the track. So 11's from bolt ons w/out NOS is definatly obtainable with traction. :cheers:

 

Go straight to the 3.42's... you'll end up there anyways.

 

Look guys I'd like to add these mods this weekend and only 3 people have replied out of 103. What is the point of the forum if you don't educate the new members? :confused:

Yes, I have the 2.73. I am seriously looking at a 3.15, but may go 3.42. If I had a 3.15, I probably wouldn't change a thing, but that is my opinion only. Others would say go to a 3.73. So, it just matter what YOU want to do.

I would personally stay with the 3.15, and I think the 2600 stall is perfect for it, and so does my Corvette guy at my dealership.

Also, make sure you add air induction and a coupler. Cheap, cheap HP.

Good luck with the mods.

Get the gears, torque converter , intake , headers , exhaust , x-pipe , and some other bolt on's and you should be there ... :D

 

In my honest opinion you will not see the 11s without at least a cam, headers, 3.42s (minimally), agressive torque converter (2900 stall or highter), pcm programming, LS6 intake (unless of course your running the laughing gas and then it will be easy). Also, in addition to the above, you will need some good rubber for drags to see 11s such as BFG Drag Radials or et streets or hoosier drag slicks.

There are many heads and cam C5s who have not quite broken into the 11s yet and without at least the above I think you are dreaming unless you went with a hard hitting torque converter, gears and 150 shot of N20 and et streets. Otherwise, forget about it, its not as easy as most think (without the aforementioned mods). The fastest C5s naturally aspirated without heads/cam usually see 12.1 to 12.4 (under perfect conditions). Don't forget its tougher to get a C5 into the 11s vs and f-body b/c of the solid axle of the f-body (camaro/firebird) and non IR suspension (unlike theC5) makes the weight distribution for dragging more desirable in a F-body.

My advice, first off definitely go with t. converter and at least 3.42s right off the bat b/c this will change whole complexion of your car and will shave .5 sec off ets. Also, from the get go ditch stock intake and go with ram air set up such as MTI< Vortex, Donasldson, etc. THen, save for stage II heads, cam, longtubes, Ls6 intake, PC etc and forget about the basis BS bolt ons. Then you will see 11s. A cheaper route would be to go with N20 (unless you prefer N/A like me) and that will get you screaming to especially with t. converter and gears.

Goodluck and be safe and I most warn you (mod attack is extemely addicting and your car will never be as reliable vs. keeping it stock. You will pay to play and i speak from experiece as i toasted my A4 tranny just 700 miles after t. converter and gears and one hour after getting car back with heads/cam :U Don't mean to bum you out, but feel you need a realistic warning concerning the fact that "YOu defintely have to pay to play! I miss the reliable confidence that my car had b/f becomming an 11 sec machine but would never go back if i had it all over to do again b/c I am a HORSEPOWER FREAK, like most others here! LOL

Welcome to the Forum. :cheers:
Take a look at my sig. I run consistent high 11's. I should be running faster, but there is a problem with the 2001 auto's and torque. I don't get full throttle until after 5200 rpm's. The computer genius' are working on that now. The 2000's do not have this problem. I would definitely go with the 3.42's., and if you can get away with it, a 3000 or higher stall converter.
I'm sure you can get 11's with bolt ons without heads/cam, but I believe you'll need nitrous.
