Cheap Street C5 This winter I wish to prove that you can build a fast C5, not spend megabucks, AND look and sound completely stock. <img src="images/icons/smile.gif" border="0">
The plan:
* Remove Heads, do port/polish (I will be doing my heads myself, but there are a lot of shops that can do this for $300-600), and use the new 2002 LS6 valves. Stock valves are about 100gm, the new LS6 ones are sodium filled and weight I believe ~60 on the intake and ~50 on the exhaust side ! I haven't gotten a price on the valves yet, but I think they'll definitely be worth the money and the increased rev ability.
* 2002 LS6 cam and springs.
* 100 shot dry. "Discreet" install. <img src="images/icons/wink.gif" border="0">
* I'm looking into a header solution. I'm not happy with what I've been seeing on corvetteforum with the TPIS headers. I've seen a lot of quality issues with folks and these headers are more than $1000 !

Re: Cheap Street C5 Good plan. I'm going to keep my car looking stock, but it wont sound that way <img src="images/icons/smile.gif" border="0">
I am going to put together some header information based on what I've been reading for the past several months and make a post tonight.
How long have you had your C5?

Re: Cheap Street C5 If I do headers, mine won't sound stock, either, LOL <img src="images/icons/grin.gif" border="0"> . I was planning on cutting the mufflers open, removing the internal baffling and welding a straight pipe through them, but I've really grown to love the sound of the C5 muffler, stock.
I revved at a friend the other day, and a C5 just sounds EXOTIC, to me. They sound great, and they aren't really a restriction like the F-body single systems seem to be.

Re: Cheap Street C5 If you dont care about resonance, and you want to make your car sound like a race car then put on straight pipes.
I'm running the back half pipes from a Borla XR-1 system and it sounds mean. The only other mod on my car is a Donaldson Intake.
The straight pipes didnt change my track times really. I ran 13.19 @ 109.xx and 13.14 @ 109.87 after. Both runs were with 2.1x 60ft times, so I know the car has a 12 in it easy. DR's are on the winter shopping list.
I'll be installing a T1 cam from MTI before spring, that alone should significantly change the sound at idle.
I'm already considering putting mufflers back on it, but I'm not out to spend $800+ on a new system so I am prepared to wait.

Re: Cheap Street C5 the 2002 LS6 valves are about $42 a piece. <img src="images/icons/shocked.gif" border="0"> I'd just stick to a dry shot and maybe removing the precats (if the 02's still have them). That and good frivetrain mods should be enough.
When are you gonna come out to the Allen GTG again?

I have a hookup at Friendly Chevrolet, I might be able to get them cheaper than that. $42 is a bunches, though!
16 @ 42 is: $672 for valves! YEESH!
At least it's not one of those fancy-schmancy 32V motors. <img src="images/icons/grin.gif" border="0"> <img src="images/icons/grin.gif" border="0"> <img src="images/icons/grin.gif" border="0">

I don't want it that loud. I want to go the completely stealthy route this time. <img src="images/icons/smile.gif" border="0"> My 1984 T/A has dual exhaust using Edelbrock Headers, Cats, and Bullet race mufflers... it's LOUD <img src="images/icons/smile.gif" border="0">

Re: Cheap Street C5 AgaveCorvette, the TPIS quality issues were prominent when they first debuted. Mine are the "new" batch and I have had nothing but great results with them. I got them for $849 shipped. They're viable solution <img src="images/icons/smile.gif" border="0"> .

I like headers. But remember, this is "cheap street" c5. $849 is way too much for the power gain. That kind of money could buy all sorts of internal goodies. If it were between $849 headers and paying $674 (list) on the LS6 valves, the valves would get the nod. <img src="images/icons/grin.gif" border="0">

Re: Cheap Street C5 You might see some gains by removing the pre-cats on your 02 if you dont get headers. I'm not 100% sure though, since I dont have pre-cats.

Re: Cheap Street C5 I'm trying to make the most horsepower for the least amount of money. Spend your $$$ wisely and you'll be faster than the guy who wasted mega bucks on things like a Corsa exhaust that gained him all of 5 horsepower and a watchful eye from the local fuzz.

Re: Cheap Street C5 Agave, I agree but LT's are no cheaper than that unforunately <img src="images/icons/frown.gif" border="0"> . I do go with the nod to valves though <img src="images/icons/grin.gif" border="0"> that you're considering. Do you think they will net you much power? Are you first to do this or have others switched the valves over, and if so, what were the gains?
Pre-Cat removal doesn't really net that much, especially on '02s, their manifolds flow much better than pre '00 manifolds, maybe 5 HP from removing those? Also it would make it a "tad" louder, very subtle though.

As far as I know, I will be the first to switch to the new valves.
I am not going to remove the precats. I, too, have seen no gains worth mentioning from doing that on an '02.
A friend of mine with an '02 removed his precats and got no gain. He gutted his cats and mufflers and got a whopping 6 hp and 4 tq. It's not worth the noise tickets and the visual inspection hassle.

Re: Cheap Street C5 It occured to me on my drive home that you could probably get a cheap, low-mile, used set of '02 LS6 valves from a tuner. I would call MTI, ARE, etc and see what they have.
