Help with mod suggestions under 1k
Alight forum friends... I am about to make my next purchase however, I am totally torn on what to do. I am thinking about the following.
Options 1)
Headers - Any set and it really doesnt matter. 1 7/8 for sure however, this would pretty much be the end of my mod list. With the my E85 I'm hoping for 25-30whp gain
Headers Price $700 - $1,200
Option 2)
Spiral ported throttle body + Z06 manifold setup + deleting cats
I feel I'm getting more for my money here and I'm leaning more towards this direction.
Throttle body Price $150-$200
Z06 Exhaust price $350 - $450
Total: $500-$750
All that being said which one would net more power and in your personal opinion and, which direction would you go? I'm sure the power would be close if comparing the two although, headers have such a unique sound to them.
HELP! Thanks for your input!

Headers....then tires.....then sway bars.....whenever you get the money.....COMPLETELY new feel for the car. Unless you start racing/HPDEs you won't need any more than that if you're on a tight budget....guaranteed.

OBX headers..best "under $1000" mod that exists for our cars.
If it were an LS2 it would probably be between those or a Ported FAST intake, but the LS3 intake is already very good.

Thanks for all the suggestions everyone! It seems people are leaning towards headers (kinda surprised). Glad I asked and I will be looking in this direction moving forward.
With the price of of the OBX headers I might still have room for the ported throttle body. Gotta love the chase for a good deal!

But I would say headers considering the sound factor alone!

I didn't think about you still being on stock injectors.
Plan on upgrading to FAST 60# or something similar at the same time. They're pretty cheap...only ~370 through Hinson.

Um...you don't want to take injectors to 100% duty cycle.
You're already really pushing it at 90%.
80-85% is where most like to keep it.

95% duty cycle when you tune it...changes in weather could very easily cause you to go into a lean condition at WOT, which would be bad.
It's much cheaper to get a set of injectors now rather than what could happen after going lean.
A tuner should not be advising you to get so close to 100% duty cycle.

Hey Floyd! How hard are injectors to install yourself? I am technically advanced but in a mechanical field other than cars/engines. I have heard from an "iffy" source it is very easy. If I dont have to tear too much apart I would consider doing them to be safe when running my LS3 with E-85. Any thoughts?

You can save yourself a bunch of money by buying a used, complete ZO6 exhaust system. You can get one very cheap and it's a bolt on! Any mod that impacts the engines breathing will require a tune to get the most out of it.

I talked to a guy this weekend at a corvette only show in MN (stillwater) that said he sold his stock Z exhaust for $400. I think $700 or so is more usual though.

If it includes the mufflers that's a great price.
