Do you already have a torque converter? A TC is the best mod you can do for an auto.

That doesnt include my suspension upgrades, or any maint. items that I have done to the car. This list should put it into perspective for you what youll need to do.

Also, this car is my daily driver.

ok cool thanks for this post

roughly on an estimate how much did it run you?


and ATX no, no TC

Many of those parts were on the car when I bought it, but roughly that list consists of $4-6k in parts depending on buying used v.s. new. Add more $$$ if you are going to be paying someone to install the parts.

I understand your goal. I too want to achieve this mark if not more. I have a 2001 ss a4. Right now I am at 343rwhp with a thermostat, 373 gears, k and n cold air intake, ported throttle body, underdrive pulley, and american racing headers that hook into a magnaflow catback system. So I have 57 rwhp to go or more to reach my goal as well. The car is a weekend driver at best. I am very tempted to just get a procharger and say the hell with it. A part of me wants to stay naturally aspirated, but the devil on my other shoulder is saying just run some boost. Either way I will build this car up. I have to believe buying some trick flows 215 cnc's and a custom cam (mild to moderate) with some supporting mods such as a timing chain, better oil pump, and a new 102 intake will get you to 400 - 425 rwhp. Also find someone who performs a great tune. I think too many mechanics don't take their time finishing their work with a good tune. Just my .02 Also you will need to get a stall.

I am at 400WHP and 390WTQ with a comp XER273HR-14 and stock 241s. Stock intake (LS6), Kooks LT, and a MagnaFlow muffler. The power under the curve awesome.

Trans24am

thats all you have in right now? and your pushing 400whp, very impressive.

alright...budget in mind?
Pacesetters 1-3/4" (TSP 1-7/8" are cheaper than kooks i think...)
True duals...outflows a catback, but yours should hold up.
ls6 intake, you already have this.
Underdrive pulley
P&P TB.
I think you would be content with this..it would land you about 340-350ish after a tune
243 heads (ls6), you can find some used for $300-$400
You could add a smaller-mild cam to that and be about 370-380, I WOULD HOPE you would be happy after that haha.
Not to mention you WILL NEED supporting mods in suspension, Oil pump, various others.
I think youll spend about $5k if you want 400Rwhp
Good luck!

Cheapest option.
100 shot of nitrous...lol

For 5k buy a used supercharger or turbo setup I think you buy a new sts kit for 5k.
