so bernd is my dak capable of going past 100 miles with turbo??or will it last like 30 and blow up(which would make me kind of happy cause I'd get a turbo V8 then)
how hard will it be to install turbo and what other parts will come with it when its all done?(igntion, fuel pump, etc) any chance of twin turbo on V6...I know u said it didn't make it better but Twin sounds so damn cool.
also u have an estimate on the V6 release date?

stop thinking like me!!! thats exactly what i said and then when my friend turbo charged his s10 it was cool but my neighbor SC s10 runs faster than my friends! the point is the 2 trucks ran basically side by side down the 1/4 mile but my neighbors truck was a hair faster now it puts about 3-4 truck lengths on it????? i also know my neighbor paid i think $300 more
also know what your getting. i wanted a 20g turbo which was $5200 for the 97-01 3.9L. and the SC was only $2400. depends on what kind of turbo/SC you get also some are better than others

Was the turbo matched to his specific application? It's requires much more than just "bolting on" a turbocharger and making power.
Between the two, i'll be running a Turbocharger within the next few months on my (formerly) supercharged V6. The nice thing about a turbo is that when you stomp on the pedal you've got full boost. That doesn't happen with a centrifugal supercharger.

you'd have to be a stupid f*cker to pay $1000+ for a turbo setup, LET ALONE $5000+. anyone who knows what they are doing can build a turbo system for $500 or less that will whoop ass. n8 dawg, you are giving out advice and trying to tell others what to do yet all your "knowledge" comes from "oh, my neighbor has this" or "hey, im paying X to have Y installed"?
although turbochargers and superchargers both have their uses, overall a turbo is a much better choice. if you just want to pay someone else to bolt something on to your truck, and you've got the money to waste, sure go ahead and get a supercharger. if you want to do a little work yourself and beat the piss out of the guy who did the above, get a turbo and tweak the piss out of it.
running twin turbos on a dakota rather than a single turbo actually seems to be the best option. the reason is that you can use two smaller turbos rather than one large turbo, and the smaller turbos are easier to find in a junkyard (meaning you can pick up both turbos for like $100 rather than having to order a brand new huge single turbo for like $700). find a good junkyard with good prices, then go around looking for turbocharged cars. most of the smaller 4-cylinder turbo cars have the kind of turbo you'd want for a twin-turbo setup, just grab two of the same type of small turbo and go to town. you will have to fabricate (or have fabricated) turbo headers, this can be expensive depending on how much of the work you do yourself. if you want to do it yourself, look around on the internet, there are some good instruction pages out there. you will also need to have an exhaust shop weld you up custom downpipes.
you will have to have some way of tweaking the engine computer. i'm not familiar with dodges, but i hear they're easy to program.
you will need to install bigger injectors (35lph+), a bigger fuel pump (i recommend a walbro 255lph pump), and a fuel regulator than is referenced to boost (i.e. that will output more fuel pressure depending on the current boost level). once you have all this installed, you will want to program the computer with the new injector size.
invest in an air/fuel ratio gauge!! you do NOT want the engine going lean under boost, it will detonate and your engine will be trashed. you always want to stay on the rich side of the meter. you can get one of the LED meters that just has the red, yellow, and green LEDs, it is more readable than the standard gauge. also, invest in a good boost gauge as well.
also, you want a good intercooler. once the air has exited the turbo, it is much hotter. an intercooler is a radiator-like device that cools off this hot air and helps prevents detonation, allowing you to run more boost. examples of very good intercoolers can be found in these vehicles: Saab 9000s, Volvos, Isuzu NPR commercial turbodiesel trucks (these are VERY good intercoolers), 89-95 Thunderbird SuperCoupes, 87-88 Thunderbird TurboCoupes.
remember this: the junkyard is your friend! if you can find a good junkyard you can get just about everything you need for a nice turbo setup from it. if you can weld, or have a friend who can, this will cut down on a lot of expense and really help you out.

im just telling him what i have saw. and my neighbors SC is the only thing he has on his truck besides mufflers. there is a place near me that puts on turbos/superchargers and they charge around $1500 for the turbo/sc and installing them. and i have never saw a sc/turbo for $500 where the hell do you live that you can get them brand new for that???? cheapiest place i have saw them was the place near me they have a sc strating at $700 and turbo at $850.
and i thought turbos were better than sc until people i know actually got them. and also in junkyards around here you can find stuff but not for 97+ dakotas and turbos wont be $100 for 2 they would proably be $250-$400 for 1 used and you dont even know if they work so why take the chances?

"...anyone who knows what they are doing can build a turbo system for $500 or less that will whoop ass."
YEAH RIGHT!! Do you know how much it actually costs for even a remanufactured (and matching) turbo (not some junkyard special either), correct wastegate, piping, intake, intercooler, fuel system, and any ignition upgrades?? $500 won't even come close.
So...on the smaller turbo's from a smaller engine...are you sure the island is correct for the application, the compressor is the correct match for the application, etc., etc., etc. It's not a simple "bolt on" like a supercharger. On the single vs. twin turbo...it depends on application and engine size, not preference. A single turbo, if matched properly, will put out the same HP/TQ output as a twin. Once you're above the 350CID range, a twin has the advantage.
Turbos also are non-linear on boost...unlike a centrifugal supercharger. You floor it, you've got max boost within a second (if matched properly)...on a supercharger, it's dependent on rpm. That also puts more into the equation of fuel, timing control, and any modifications to the engine that may be required for the higher level of boost. A custom PCM program can only cover the linear side...not the non-linear.
Installing 35#+ injectors on the Chrysler OBD-II system is just stupid. You'll need more than a simple PCM reprogram...FAST, Haltech, Split-Second are all companies that have a programmable fuel controller for this. (You can also tack on $500+ to your turbo system.)
"...remember this: the junkyard is your friend!"
Also remember...you get what you pay for.

BERND when did your sc kick on at 2500rpm's? b/c thats what the guy said mine would kick on if i get one. and turbos on stock cars atleast older talon's dont come on until you get up to 3000rpm's.
and sonsidering right now run a 16.3 with a turbo what do you think i wuld run.......mid 14's?

what bernd says makes more sense. if turbo was so cheap everyone would be trying to do it. and how easy is it to find 2 identical turbos at a junkyard?
bernd will your kit require a pcm reprogram? and how is the R/T twin coming??

N8: My S/C started making boost at 2000rpm due to the smaller pulley I was using (11# pulley). Stock 6# pulley normally starts making boost at 2400-2600rpm. It all depends on the ratio of the pulley and engine speed.
On "factory" vehicles, the S/C and Turbochargers are detuned for a reason: LIABILITY. They don't come on as quick, make less than optimal boost, but work well for the average driver. This is why there's such a thing as aftermarket parts. If everything was optimal from the factory, we wouldn't need such things as aftermarket boost controllers, headers, modified throttle bodies, etc.
Since we're using no more than 8# boost, the stock PCM with some mild "tweaking" to the fuel and ignition system will suffice.
