Thread: Performance Upgrades

not quite 1 million just 999,999

Theres really not that many steps for a 3.4/3.5 setup.

Here let me break this down into a "million" steps:

1: Intake

2: Headers

3: Plugs/Wires

4: Pulley Drop

5: Tune

Now if i can count right, thats only 5 steps.

I made the same mistake as this guy did, but I bought a ZZP 3.5" mps. Had that thing for over a year and a half before I got my headers.

And the thing he got from summit racing says can help your engine produce up to an additional 25hp. With proper supporting mods i could see that being possible.

So i have vacation coming up shortly, where is it recommended i start off?

Dude....

Did you just not read the list i made you?

Its in order.

Do the 3.5/tune/and colder plugs all at once.

while you have the supercharger off port the outlet and paint it

And like Matthew said here..

Do your LIM Gaskets first/tune up.

Make sure she is in strong running order before modding it.

its not gonna get you back to 240whp you never had 240whp and they never claimed this car to have 240HP at the WHEELS that is your crank HP rating from the factory and they never claimed the car had 240HP really they claimed the engine had 240hp and im sure on a engine dyno a stock L67 would have 240 HP anyways nicks right crank horse power is lame

yeah i phrased it wrong usually a good 3.4 will get you at around 240 whp

1: Get a scan gauge/tuner

Fixed.

Just buy headers, plugs, pulley, and a tuned PCM (if you dont have a tuner program or know someone with one) for the mods all at once, and spend a day or how ever long it takes you and put it all in at once. Make your own intake, And I know most will disagree with me but you should be okay with a basic 3.5 setup and no tune "right away". Im currently running a 3.4 setup on a stock tune with almost no KR

Speed daddy headers off eBay are the best for the price

Or what are the other ones called SSAC i think? Might be the same as the speed daddy's? I don't know I have pacesetters.
