500+ hp
After saving for over a year now I finally have about 10k to put in to my 03 m6. Here is what I want to achieve...I know there are lots and lots of combinations you can go with when it comes to N/A. The question that i want to know is and I want anyone and everyone to chime in on this. Can I build with a 10k budget a N/A C5 with around 515-530rwhp. The only thing done to the car is a z06 ti exhaust if you consider that a mod. Let the chiming in begin!

Ive seen H/C stock bottom end cars over 500rwhp. You don't need a built engine to do it. Picking an N/A route depends on how you want the car to behave. I think the easiest way would be to supercharge it if all you are interested in is that HP number. Also factor in the cost of a clutch that will handle this power and hardned output shafts.

I wanna go n/a for the reliability issue and for the fact that how fun would it be to have an all motor vette laying down hp numbers that a procharger or paxton would put down. Dont get me wrong ATI and ECS put down some very impressive numbers but the cost to install a supercharger will leave me with nothing but maybe enough to get a clutch installed. I know h/c can net me somewhere around the 440-480 range with your basic longtubes,exhaust,xpipe,fast 90/90. I am figuring in all the factors of upgraded rear-end ,clutch,halfshafts,etc. If someone on here knows of a person making that kind of power with just h/c and bolt ons send me in there direction or list the shops name. I live in tennessee and im having problems trying to find a reputable shop to install everything.

What are you looking for torque wise? If you raise your torque (not including gear mods) Hp numbers are almost certain to follow.
My suggestion would be:
(induction)
- A "True" CAI (vararam, honker, vortex or hurricane)
- Good plumbing from CAI to throttle body
- A 90/90 TB/intake manifold combo will be your friend
- H/C package (there are countless combinations)
(Fuel)
- the proper injectors and fuel pump to feed the monster. Ask your tuner what is best to match your H/C package
- make sure the rest of your fuel system can stand up to the demands of your engine
(hardware)
- you may want to consider boring/stroking to 383 if your budget allows. this will let you keep your original block which should be less expensive than a whole new block. HOWEVER you also hv to consider the cost of the matching hardware: pistons, connecting rods, etc.
- With minor upgrades, the trans should be able to take 500HP depending on it's current condition.
First, decide what exactly it is you want to get to your goals (reguardless of price)

a better goal would be a time you want to run at the track, one shops 500 RWHP does not equal anothers, so what you should be thinking is i have ten grand and i want to run (insert your track time here), thats a much more realistic goal to shoot for

That is what I thought at first. Then I saw the car. Fine on the street at any kind of speed, even traffic. Can cruise in traffic or make 500 mile road trips. Then you can drive it to the track and run mid 10s all night and drive it home. The reliability on the engine has BY FAR exceeded what I thought it would. It holds up very well.

Did you take a chance to read the thread I opened on my quest to my 511 rwhp / 455 rwtq on a stock bottom end 346Ci NA ???
Some of your questions can be answered in it...
Don't ever consider only the engine aspect to make it reality and drivable on the road with reliability!!!
The ones that are saying "no problem, here is the receipe for cheap" for sure have never been there...
Let me know if you need some more info

Here's an idea...403/L92/L76 setup. 500+RWHP 470RWT. 380RWT at 2200. Budget will be close. The car drives better than stock with all that RWT. The car is a beast..

If you have $10k to put toward your Vette to get to 500 hp AND be reliable, look into letting Lingnefelter Performance rebuild your engine.

The problem is... you're also going to need other mods to get there. Headers, a good intake setup, a good clutch, or a strong A4, and you're also going to want stickier tires so it hooks and you can use the power rather than blowing the tires out. With the stickier tires you're going to need at a minimum a DTE brace, and stronger axle shafts. So will $10K get you 500+ horsepower? Sure. Will it last and be reliable? Doubt it.

What do you want your car to do?? 500+ HP and street drivabilty are not always the same.
and when you get 500 plus ponies if your car weighs 3400 lbs with you in it, what is it going to matter with that much weight?
Gutting you car to reduce wt makes your car faster then adding more HP.

Hi AU N EGL,
I will not agree with you on this one, as an axiom nonetheless.
It is going to be a question of choice...which is a very important component of American way of life.
You can go on a 346Ci NA stock short block short way with a big cam and good flowing heads and free flowing exhaust and EWP and obtain your numbers...you have it!
You can go a similar route I choosed and have a well qualified engine builder matching all the peripherals with having in mind your goals and obtain the results with my ZO6.
Different approach, different price, different results.
My car is a DD, my wife use it to go shopping sometime, and it is far over 500rwhp on a 346Ci.
Did you take a look at this thread?

that is why I said "Not Always"
and to look at what you "really want for your car?" Just big numbers? Big numbers AND drivabilty AND reliabilty? Big numbers down low to get off the line or out of a corner? or what?
I have driven a 525 rwhp Z06 that was not streetable. Why? it had 535 rwtq flat torque curve at 3600 to 4600 rpms with a light wt racing clutch that did not drive UNDER 2000 rpms.
Also drove a 500 rwhp Z06 that was just a dog under 3500 rpms, and ripped the pavement to pieces over 5000 rpms. ANd this owner wondered why stock coupes were walking away from him out of coners.
YES I agree with you that for these kind of numbers a well qualifed engine builder should be used.
To get these type of numbers, it is a combination of everthing, not just bolt on cam and heads.
It comes down to what do you really want your vette to do?
