I'm currently updating this page, bear with me. The other 8 pages are still there. There are a few photos missing, since most of them were over a year old. They will be replaced with current ones soon.
This is my 1991 Dodge Dynasty. This car comes from the factory adequaely powered, well equipped, and very user friendly. However, just about every car has room for improvement... or just tweaking for personal preference. I am posting all of this to help people. obviously, it could all be done on another car like this, but the main idea can be used on any overland transport module.
(updated exterior pictures coming soon)
There are three powerplant options, and two transmission options (that I know of) for this car: for engines; there is a 2.5 litre I-4 SOHC, a 3.0 litre V-6, and a 3.3 litre V-6 (New Yorker and Imperial had the 3.8 litre V-6 as an option). For transmissions; there is a 3-speed hydraulic transaxle (A413?), and a 4-speed electronic transaxle (A604/41TE). Thankfully, this car has the 3.3 litre V-6 paired with the 41TE, it makes for a smooth, efficient ride... but I want more.
What I'm looking for is a comfortable, reliable, and economical vehicle to drive. Absolutely stock, it's tolerable... but a little work and it's become comperable to modern cars. Aside from the paint, it's aged quite well.
I use this car for work, and my own personal use, so it has to meet a wide range of demands. I need something with outstanding endurance, brakes that will constistently stop this car faster than anything I feel like tailgating, enough power to quickly launch this brick on the freeway when FULLY loaded, susspension that can handle Florida's shitty ass roads and extreme overloading, an interior comfortable enough for me to be in the car 40-60 hours a week, and fuel economy that won't burn a hole in my wallet (and down to the earth's core).
The first thing I worked on were endurance mods:
I needed everything to stay in working order under any conditions I decide to abuse the car with. The most important thing I could think of is keeping the engine cool... enter the Modine radiator... and a accessory belt that won't fly off in the rain: Goodyear makes a belt that does quite well, I've had it on there for three years, and it's never come off, and it shows no signs of wear. I think it's called a "Gatorback". Another good idea is drilling 1/8" holes in a zig-zag pattern on the smooth idler pulleys, they seem to be where belt throwing problems originate.
200,000 miles and counting...
I made a bug screen with some fiberglass window screen, mason's line, and some snaps (usually for marine applications). I can remove it when it's not bug season (seems like every month it rains is bug season).
After fifteen years the factory exhaust wasn't doing too well. It did what it was supposed to, but it also did a little more... I hate rattles, so it had to go... time to upgrade.
Obviously, I'm in to ultra low maintenance (like none), so stainless steel was a must (titanium is expensive as hell, plus I can't find anybody that will weld it). I replaced everything from the madifold flange all the way back, using 2.5" T-304 extruded stainless pipe (don't want any seams busting).
For the cat, I just used a plain old Hi-flow found at any rice shop. It was really small... it's perfect. To replace the resonator, I used a 4" round 16" long Magnaflow "strait-thru". It doesn't muffle much on it's own, but it does more than a resonator will (and not block flow). The intermediate pipe between the resonator (well, where it used to be) is a tricky piece, it has to snake around the rear susspension... which is designed to barely fit a 1.75" pipe through (and it would always rattle if somebody sat in the back seat)... 90 minutes, and sixteen precision bends later, the 2.5" pipe runs through there without a rattle in two years. To tie up the end, I sprang for a Borla. It cuts the noise down to almost non-existent, I can't even hear it on the freeway.
Opening up the exhaust is always a compromise, I lost about 2mpg in the city, but I gained about 3mpg on the freeway. Since 80% of my driving is on the freeway, it works out very well.
Oh yeah, there aint a single one of those shitty ass clamps on this exhaust, I hate those things. Every joint is welded all the way around the pipe.
I have a hood ornament that shows up once in a while :P
I frequently carry a full passenger load, plus 500+ pounds in the trunk. To keep this car's fat ass off the pavement, serious susspension modifications had to be made. To keep the car level with the road, air bags were the only option. I wired up a compressor, so I can adjust ride height anywhere.
Now the ride height problem is solved, but with extra weight, comes extra susspension travel and body roll. KYB Gas-A-Just shocks are the stiffest damn shocks on the planet, and they seem to last forever. They keep bounce to a minimum under any load conditions, and the ride is still smooth when the car is empty.
I'll install variable-rate coil springs and a rear sway bar someday. More susspension stuff on page 6.
More items for work include a CB radio (speaker output wired into the stereo) with weather radio and external PA loudspeaker, 16 pattern 4-way strobe lights (they seem to interfere with any radio transmission and bluetooth devices), multiple 12volt sockets for phone chargers and things, 120volt inverter, red map lights for the navigator (well, they're really for me, I don't want to be bugged by a light while driving in the dark), a spotlight for working at night, many other things that will get mentioned later.
This car comes with a good array of instruments for most people, but I want it all. I added a vacuum gauge, tachometer (leave a message in the guestbook if you're stumped, the 3.3/3.8 Mopar engines are a little tricky), trans temp, air/fuel (useless piece of shit), Autometer D-PIC... more to come. I'll be adding an engine oil temp, and a wideband A/F gauge later.
I also changed the factory instrument lighting to red... red is best at night, green and blue are the absolute worst. Don't believe me? Ask any ship captain or airline pilot, all their gauges are red for a good reason.
I like to listen to the stereo while I work, and the car will be off for at least two hours daily with the electronics active (parking/strobe lights, radio with subwoofer, interior lights from door being open, electric fan in the summer, etc. Electrical upgrades are imperative.
I installed an Optima yellow-top for the constant long cycles, it lasts a REALLY long time. I had the stereo, a soldering gun, and a floor lamp from my living room going for 9 hours while working on a buddy's car once. The car fired right up after all that power was used.
Another important thing is the right connections... let me put it plainly... LEAD SUCKS ASS! Autozone sells marine clamps made out of brass for $4.50 a set. They have a stud and wing nut for way better connections that any clamp-on terminal, and they haven't shown even a hint of corrosion in the last year.
For a better running engine, lose the OEM ignition wires. The wires are more important than the plugs themselves. I chose MSD's "super conductor" wire set, because of the easy availability, good durability, I have a couple spares (set comes with eight plug wires, plus a coil wire), and I assemble them myself, so they can be the exact length I want. However, radio interference from the direct ignition sustem interferes with AM radio.
I used platinum+4 plugs, but I kinda want something else... maybe E3? I want something thet doesn't have the ground in front of the electrode.
People drive like total dickheads in Florida, and the factory horn wasn't nearly loud enough. I installed air horns in their place. They're louder, but still not loud enough (a grenade may be loud enough) I don't like the sound either. I'm gonna try some "freeway blaster" horns soon, they are at least twice as loud as the factory horns, and still much louder than the air horns... maybe I'll install four instead of two :P
Another endurance mod would be oil filtration. I'd like to be able to drive anywhere in the country... and back, without having to change the oil.
The "Trasko oil refinery system" gives conventional motor oil a service life of 10,000 miles, I assume full synthetic will get that too. It does.
This is what the oil looks like after 7,500 miles, I think it's pretty good. These filters only let particles less than .01 microns through, and all are carbon. All metal, water and acids are removed on the first pass. Remember, carbon in the oil is okay, it may turn it a medium-brown color, but it will not reduce the effectiveness at all. Carbon is actually a very good lubricant. The oil isn't actually "dirty" until it feels sticky. This thing was $75.00 and the refills are $10.00. You can get this at traskousa.com.
I upgraded the brakes on all four wheels, more detail on page 5. The rotors are from a '90 Daytona ES, Shelby, or IROC R/T, The rear calipers and backing plates are from the same car. The front calipers and brackets are from a 2nd gen. Grand Caravan with the oversized brakes. The Daytona calipers and the Caravan rotors are incompatible with the Dynasty, this is the best combination I know of. This setup will stop this rolling cinderblock from 60mph in under 120 feet.
For air filtration, I eventually settled on the Accel "power filter". It's a re-useable filter with comparable flow to the K&N, but it catches everything other cotton filters let through.
For the crankcase breather, I couldn't find a foam filter (I'll just make one eventually), so I made a little bong thing filled with oil. All the air than enters the crankcase passes through the oil in the jar, which cleans it much better than that crappy gauze thing.
Chrysler PCV systems pass a constant, steady flow of air through the crankcase no matter what the manifold vacuum is. Whenever the engine is running, a steady amount of air is bubbling through this jar.
