I want to add more performance modifications to the 07 Pacifica (Signature Series).
On the way are:

- 1.75 inch suspension drop (progressive lowering springs)
- 275/45x20 on 20x8.5 or 20x10.0 rims
- K&N air filter

What performance modifications have been done to the Pacifica?
Engine (forced induction?), Suspension (shocks? Sway bars?, bushings?), Chips, Transmission, Chassis (tower brace, stiffening), Steering (heavier feel desired), Brakes, Air Intake, Ignition, Fuel delivery, etc.

List all you have done, heard of or seen (links).

Thanks.

i had an 04 pac the only thing i found was a k&n filter they make drilled & slotted rotors as far as chips go they are junk good luck
finding mods

 

Did the K&N make a difference?

 

not realy maybee a tad better gas mil but cheaper in the long run never have to buy filters again just clean it

 

The rear suspension is a Mercedes designed auto leveling type. I wouldn't touch it.

 

Clearly: no!

Not even to my sensible foot and behind. And not even at wide open throttle (when the increased flow should show).

What are you trying to do, i mean this isnt a vehicle that you can race, you wont increase you 0-60 by more then .01 its cheaper just to save up and buy you a crossfire.
its just a pimp wagon. ( but if you really want to do something i would go with a better exhaust, 250-425 depending on what you want)

 

Well: believe it or not, I am one of those drivers who try to combine the utility (hence the wagon) with a decent performance/ride (I wouldn't think of the Crossfire). Think a combinaton of a C6 Corvette with an R-Class Mercedes. Also known as: Sport Wagon. Obviously NOT the type of driving enjoyment for you, but nevertheless a class of cars quite commonly found in Europe (f.e. 2007 Mercedes-Benz R-Class below) and enjoyed by a selected few enthusiasts here:

Performance & Efficiency Standard Features
- 6,208 cc 6.2 liters V 8 front engine with 102.2 mm bore, 94.6 mm stroke, 11.3 compression ratio, double overhead cam, variable valve timing/camshaft and four valves per cylinder
- Power: 375 kW , 503 HP SAE @ 6,800 rpm; 465 ft lb , 630 Nm @ 5,000 rpm

While this would be nice, I am trying to get close without spending the kind of "dough" (as you would likely all it); and at the same time enjoy the DIY part.

So the K&N didn't make a difference? Can't seem to find a cold air system for this car, only the filter. I've put the K&N kits on my other trucks and it helped with throttle response and bottom end torque. I also posted a new thread a couple days back about Hypertech's power programmer for the 3.8liter,any thoughts on this?
