Not much that isn't pricey. Speed is money. Start with long tube headers. $1000

The best $25 dollars you can spend and see it is to curve your distributor, a curve kit about $12,..the correct vacumn advance can about $13.

You will feel it through all Rpm ranges, and most are set up wrong..

Next would be to get your AFR correct....not too rich, not too lean...just right for cruise and power

If auto best mods are toque converter, headers and a tune. If stick a 3.91 gear, headers and a tune. Unfortunately none of these mods are “cheap”. The late model gto is not a cheap platform for upgrading.

Horsepower = money$$$
I was lucky to get a new/used Vortec blower kit from A&A and installed myself on my 04 Z06. Really, much easier than
expected. Would be even easier on the GTO. After getting it tuned, it ran just under $4k. Picked up a safe 170rwhp.
Headers are the only needed accessory for a small blower/turbo kit. Gets around 22mpg tooling around, also.
You will also need a good supply of cash for rear tires.

Also, for a deal on coated Pacesetter #72C2258 Headers $329.58 free shipping:

https://www.ebay.com/itm/Pacesetter-...cAAOSwowdciuiw

I installed a set of these non-coated in June, 2007 at 53,289 miles. About 8 months ago, at about 206,000 miles, I had a small rust
hole over the #7 tube at the flange. I put a small piece of header wrap under a hose clamp and still going strong. I bought a set of
these (were $358.03 then) and will install when I feel like it. Dropping the steering rack down isn't any fun.

These are not stainless steel, but they are not a thousand dollars, either.
My uncoated headers cost $285.97 in 2007 and I got 12 years and 153,000 miles before any problems.

Spot on GTO44!????those LS motors are awful good, now if you have the earlier version that have PCV valve..I would suggest as a lower cost upgrade an ME Wagner dual flow PCV Valve.

That valve I run on my 460 Pontiac, and it will do a lot of nice things for your engine. First it will pull a vacumn in the crankcase of 1 to 3 hg 99% of the time and you tune for your motor, on the motor. Second it will pull out all of that blow by crud and condensation and some car ones up oil.

Best is to run it with a catch can and then your PCV feed into the intake is also all cleaned up, better for your mixture, cleaner for your intake, your valves and your cylinders. Will leave lots of less carbon gunk.

In addition it will allow the downstroke of the piston to be pushing against a slight vacumn rather than a slight pressure, a possible small horsepower gain. It will also stop annoying leaks from seals and gaskets and oil out the breather.

Your current cheap $6 PCV valve will only pull a vacumn 10 to 30 % of the time. See the tests on ME Wagners website.

So all of that, with work you can do yourself and you donít have to have major engine changes or even crawl underneath it.

Cost the Wagner dual flow is $129, catch cans run from $20 to a few hundred. Get one with a dipstick or a sight glass. I use a Radium Catch.

can.

Make sure your ME Wagner vale is baffled so you donít lose too much oil.

So $140 to $500,....Cleaner, more power, less leaks, better AFR mixture you can do it yourself.....that is a good upgrade even on an LS motor.

Then buy you a bottle of Redline S1 fuel system cleaner and put it in your tank, and use it per directions, cleans valves cylinders and keeps intake and carb clean....

It has the only real cleaner for high temp carbon deposits, PEA....which is Techron invented by Chevron Chemists and used in their gasoline.

Now donít you feel better? ....Even though you are missing a distributor!
