'98 Durango 4x4 5.9 Engine Mods

I still am in the process of doing engines mods and will post updates as they are done.

Cold Air Intake

Optima Battery with a polished aluminum holder.

Bosch Electric Fan from a Volvo
After removing the stock clutch fan and installing this fan I have felt the increase in horespower which some claim is 17%. I can now feel the power and pickup since the stock fan has been removed.
This fan moves a lot of air and has kept my engine running cooler than the stock fan did.
This is an alternative to installing an aftermarket fan to cut down on cost.

After the fan shroud has been removed. Remove the belt then the fan. They do have a special tool to secure the pulley if you can get a hold of one.	I removed the two top mounts with a hacksaw. You can see the one in the top left before it was removed.
The arrows are pointing to where the top mount was removed. This is so it will clear the A/C line. There is a gap of about 1 to 1 1/2" from the top. This has not effected cooling.	Info on the type of fan I used. I picked mine up off of Ebay for about 15 dollars.
I used a zip tie to hold the fan in place until I could install all four of the Nylon Mounting Rods	Arrows point to where the top two Nylon Mounting Rods are installed. The holes for these were already in place and the tie only went through the radiator
I had to drill holes for the bottom two ties. They went through the radiator and the A/C cooler for the bottom two.	This is the bottom tie coming out through the radiator and the A/C cooler. These took a little patience to get through both the radiator and A/C cooler.
The fan left a 4" gap at the bottom of the radiator. But with the amount of air it moves it still keeps the engine cooler than the stock fan.	Here is the fan installed.
Nylon Ties I used to secure fan. You can get these at any automotive store. They are sold for mounting transmission coolers.	HERE is a link to a recent addition to the fan. I installed a Variable Speed Controller on it.

Installed Mopar PPH Headers.
They are polished stainless and are ceramic coated. The exhaust is all stainless from front to back.
I have a Pypes Cat and a Flowmaster 40 Delta Series Muffler in line ending with a polished stainless Flowmaster Tip.

	Pypes Cats
This two chamber design incorporates Flowmasters patented "Delta Flow" technology. The "Delta" deflectors result in increased scavenging for better performance and reduced interior resonance over the standard 40 series with a nice growl outside the vehicle. Sounds great on late model performance cars with catalytic converters. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability. Interior is all stainless.

I did this Kegger Intake modification after reading that it takes away very little bottom end, though gaining a lot of upper end power.
The instructions are located [url=http://www.dakota-durango.com/forum/showthread.php?t=58960&highlight=kegger]HERE[/url].

Cut them down with dremel	Here is the attachment I used, a cutting wheel
Closer view of them cut down	I used this attachment to bevel the edges of the cuts
After beveling them	Then I used this sanding attachment to start smoothing the cuts and polishing the gasket ports and injector ports
	Then used this wire wheel attachment to further polish and smooth everything. Plus down into the tunnels as far as I could get
Then I bead blasted the outside	Also bead blasted the inside
Ready for primer	Shot it with self etching aluminum primer
Then shot it red

Throttle Body, ported and polished by [url=http://www.dakota-durango.com/forum/member.php?u=4748]bwdakrt[/url] on the Dakota Durango Board

And yes, when I posted this picture after I shot it red, it was pointed out to me that the linkage was installed upside down when I put it back together.

Before	Before
After removing old throttle body, alternator, a/c and bracket, I also removed injectors along with injector holder, so I could paint it black.
Old Kegger gone. You can see a lot of oil buildup around the Distributer, seems the Kegger had a nice leak back there.	Old Valve Covers gone. I also cleaned up around the Distributer real good.
Mopar Magnum Valve Covers in place. I used aluminum powder coated t-bolts to hold them down.	New and improved Kegger in place
Almost there!	Finished and cleaned up!
