I'm looking at increasing the performance of my stock '02 6-spd coupe's LS-1. The only thing I've upgraded on the 'Vette thus far are the shocks and sway bars.

I know there are 427 options out there, but I don't have that kind of cash. In any case, I've read quite a few comments that say while the extra horses are great, it's not worth the money you put into it.

To be honest, if I could have ordered a LS6 engine/powertrain set-up in coupe form, I would have. (Curse you GM! Well, not really.)

What I'm looking for is something that's Z06-esque or better. Anyone have any suggestions for parts/pieces/perf.-package as well as shop to install everything? (I live in the Macon, GA area.)

Thanks in advance for the comments.
:cheers: :steering:

 

Im not the most informed on this subject but I would think that a good set of long tube headers and a mild cam job would put you up or above z06 specs. Just my .02 Hope that it sets you in the right way. :cheers:

 

Step 1: Air intake system. Blackwing if you want simple install and ~10rwhp gain ~$200, Vortex if you want a few more ponies from its cold air advantage ~$240, or a Vararam if you want the best all-out air intake system that gives the best gains.

Step 2: Muffler system for improved sound, looks and 5-8rwhp. Brand and model would depend on what type of sound, and how loud you want your exhaust. There also many tip options. They run from $400 - $800.

Step 3: Long Tube Headers, many options available, I highly recommend Stainless Works, which get you the most for your money: best quality and fitment, excellent power gains (~15rwhp without tuning), 304 stainles steel construction with lifetime warranty.. All for around $1000.

Step 4: For an M6, I highly recommend an aftermarket shifter. It may not get you any extra ponies but you do notice it, and love it, everytime you drive your car. There are a few to choose from. I recommend either the Hurst or the B&M Ripper. They are all around the $170-200 range.

Step 5: Get a good PCM tuning done on a chassis dyno with a wide-band 02 sensor to get your air/fuel mixtures perfect after you add all of the mods previously mentioned.

Step 6: This is where you have to start dipping into the engine internals to gain any more power that is worth the money. You can go with a cam-only install and get ~30+rwhp depending on how agressive you want, etc. Then there are heads/cam packages that start in the $3500-4000 range installed and tuned, or less if you want to do the install yourself. You can also go the Supercharger or Turbo forced induction route if you want to not touch your engine. You are looking ~$5000 for the kit and then another $2000 for install and tuning.

If you are have any questions about anything or are interested in the best available pricing on anything I have mentioned, please feel free to email me! mattglas@sympatico.ca

300 shot of nitrous, $1000.
RWHP=615 :crazy: :crazy:
dont worry about you engine and trans, find a crooked dealer, pay him a coupla bucks to remove n02 and claim it on warranty :reddevil :reddevil :D

 

Since you are in Georgia, Call Lamar Walden Automotive in Doraville. They are the best shop I have ever delt with in this area, they have a ton of LS1 experience. They are not one of the sponsored vendors on here but they do very, very high end work on these cars. They have built numerous C5R engines, so that gives you an idea of there status. You will also save alot of money going with these guys. Their tuner is Tom Garland (nevrenuf) here on the forum. He is the MAN when it comes to tuning these cars.

Ask for Rob, tell them that Dave Thompson sent you. You will not be sorry

 

TWIN TURBOS!!!


I have them on my 2000 SS and it is a trip to drive and hp/tq out the wazoo. No heads , no cam- all stock innards. At 5lbs boost she has 486RWHP and matching torque. Next stop a stroker and a REAL REAR!!

:iagree: :iagree: Like always MattG has hit the nail on the head!! :yesnod:

If you are just in Georgia then it might benefit you to contact More Performance up here in Charlotte... moreperformanceinc.com Not too far away and they do incredible work! :yesnod: They have done all the work on my car and I make pretty good power (see sig) have spent over $30,000 in last two years with them and have loved everything they have done so far :smash: :yesnod:

 

After you upgrade the air intake and possibly exhaust you will find that further performance mods are very expensive on the C5. I think you can run the 1/4 at 110-112 MPH without breaking the bank, but, going much faster is going to cost big bucks. Heads/Cam, Cam + Headers, FI, Stroker, whatever : they are all extremely expensive. MattG is right on the money with his recommendations. The only thing he left off the list is a gear upgrade.
