Message:
About how much boost will this turbo produce?
I am not looking for anything too much, just to add a little bit more power, over all of my other bolt ons.
And what exactly is the size of the inlet and outlet of this?
I can get the innercooler also.
I am only going to be sending about $100 on this, is it worth it?

Turbo is going to be a difficult thing to deal with, you will need to change injectors, your computer will not know what the hell is going on and it will probably detonate if you don't retard the timing which means custom computer calibration. Your modifications to make this work will stem well beyond $1000.

The only problem I am going to encounter right off hand would be retarding the timing, if need be. I was just wanting to know how much boost this one would produce and how well everything else would hook up.
I have almost everyother thing taken care of so far. And I have plans on how I will hook it to the exhaust so that maybe it will not cost as much.
I think that I can get this thing hooked up and everythings else taken care of for about $300-$400. Not too much if it will give me what I want. I don't want alot, just a little extra.

i think you'll wind up grenading your engine if that's all your gonna spend to install a turbo. i hope you've done plenty of research and know what your doing. even just a little boost can be damaging if not done right. good luck and i hope it works as you would like it too.

Like I stated in the post before, I have everything that I need except for retarding the timing. I have some knowledge with this stuff and have a few buddies that know what they are doing. I just need some answers about the Turbo.

Allied Signal was bought by honeywell. there is some turbo info on their site. it is possible they could answer your questions if noone here can. www.honeywell.com

Watkinstick, Good luck with your project. I have been building my remote turbo system on paper now for 3 months and shopping for the best prices. I know you say you have everything covered and only plan on spending 300-400 hundred. A quality external turbo oil pump costs $200. not to mention a $100 blow off valve and if you are looking at the remote system which hangs the turbo where the muffler is, $150 for an external wastegate. Oh yea $400 for the MSD 6 BTM. this will auto retard the timming based on boost numbers. and then there is the custom pipes and welding needed. My project is up to $1200 so far.
Hope everything works out. Let us know.

Intense,
I had sent you an email a week or 2 ago. How much boost will this turbo produce do you think? Is the turbo and intercooler worth the $100, or not? A mean $100 for both sound good to me. (the only thing that I don't know about a turbo is the numbers, that is where I need help.
Steve, the wastegate and BOV are not going to cost me that much, I have connections, which is really nice sometimes. And the piping all I need is for someone to do the welds. I am thinking about getting a Supertuner (you can retard the timing with it right? from what I have read). I have a MSD Blaster SS coil and new plugs, wires, cap and rotor - so there is plenty of spark. The oil pump is one thing that I have not got (but I am sure I will not spend $200 on it).

You should be able to trim that budget a bit. Found on eBay - MSD 6 BTM $122. I've found other things like suitable waste gates and stuff too.

Their was someone on another forum that did a remote turbo for his 3.9 v6 dakota and he found that the computer seemed to compensate for low amounts of boost just fine.

the computer will not compensate for boost at all. The single bar map sensor will actually fuk up when it see's boost... it will be out of it's operating range.
watkin's, i doubt my e-mail is updated on this site so i'm not sure if i got that email or not. The turbo i ran was a Garret TB0301B. It had an compressor inlet of .42 a/r and exhaust turbine of .82 a/r, and it was considered small. On a 3.9 a turbo that size could make about 10 lbs of boost through the operating range of one of our 3.9's. Your compressor inlet is the same size as mine, but your outlet is considerably smaller. It will make boost, and it would make it very fast, no lag at all.. but that turbo would be finish spooling sooner and actually overspooling before you hit the end of your power range. You could burn it up really fast and possibly damage your motor.
Dont do what i did and go cheap.. it worked but just barely and looked like poo.
there's a guy around my area selling a nice T04B for $300 i believe, which would be perfect for a 3.9 and be very adjustable.
Greg K,
you mean your truck didnt come with one of those? my 98 did.

It spooling up quickly and not being able to keep spooling at about 4000-6000 rpms is what I was worrying about. Though I do not get up that high unless I am messing with one of my buddies, or in the times that a ricer burner tries to race me. I usually keep it in between 2000 and 3000 rpms under normal driving conditions. But if you do not think that this will work well with my truck, I will try to find a bigger one. If I can get it for fairly cheap.
I had plans on mine that would not look like poo. I am just needing to get the right size turbo. I don't want to go too expensive, I am on a tight budget. I am in college and just had to move out of mom's house and I am having to pay for my own place, so it is a little hard now.

Ill have to look that site up then maybe he did something to the map i didnt notice. He was only running 5 lbs of boost max anyways.
Dang i cant find the site oh well... I did find the info for stoping the map from bugging out going into boost. It was something that crossed 2 wires using a zener diode so it dumped voltage when hitting boost to fool the computer into not seeing 0 vaccuum before WOT.

yeah we did the diode on mine when i ran boost... but a single bar (single atmosphere) map sensor will not adjust for boost. That's when you start needing 2 and 3 bar maps.

maybe its just me, but i've never heard anything concerning the map sensor and boost from all the 5.2 5.9 supercharger build ups, nor the few turbo builds ive read about. isnt it all the same map sensor?
also, themongrel over at dakotausa never mentioned the map sensor in explaining his remote turbo on his 3.9, and he was quite detailed.
not saying that its not possible, i believe you, intense, since you've actually run a turbo 3.9. just wondering, was there a different sensor for your year, or something different with the 3.9s map?

all the sensors are the same. I'm not saying your truck will not boost, or the computer will not run anything.
Anybody that has made real boost, ask them about the part throttle/part boost hesitation that the truck gets into if you're just cruising and decide to give it a little gas. The motor starts bucking pretty hard as the computer doesnt know what to do with the MAP readings. Several people have done what we did to mine and some people put a check valve in the vacuum line going from the throttle body tot he MAP sensor, but they all work the same.
now i never had this problem with the weak little powerdyne i had, that only put 4 lbs of boost in the intake with a 6 lb pulley. I only had this problem with the 7-10 (spike) boost my turbo generated. The reason for it not being a problem on the powerdyne is because it didnt see any boost unless i was above 3000 rpms and WOT.. it was weak. The turbo could make boost on part throttle runs and full 7-8 lbs at 2300-2400 rpms... it was pretty damn nice i tell ya.
but the main thing that i am saying is that the computer will not add extra fuel when it sees boost, because it's not designed to see boost with it's single bar MAP sensor. What happens is when you turn your truck to the on position, the computer takes a quick reading of the volts and uses that as the maximum voltage in the maps working range. If the MAP senses anything above that voltage (Boost), it doesnt know what to do and most trucks will get the hesitation that i talked about before. By measuring the MAPs max voltage at the "on" position, but not started, Bernd went shopping for a zenier diode and a resistor to keep the computer from seeing voltage above the initial input. This got rid of every bit of hesitation and bucking that i was seeing, but this did not add fuel... it regulated it better.
FMU's and piggy back computers are just about the only options for adding fuel to boost.. stock computer wont do it.

awesome, thanks for the explanation intense. i'm wanting to get a remote setup on mine eventually, and its great learning more about the extras and details that go into a project like this.
"The turbo could make boost on part throttle runs and full 7-8 lbs at 2300-2400 rpms... it was pretty damn nice i tell ya. "
sure sounds good to me.
