 Subject: Designing a remote turbo system
IP: Logged
Message:
I am in the process of designing a turbo system for my 1996 dakota with a 318. I will be making it a remote mount turbo system. I will be mounting the turbo where the spare tire used to be. I have seen a couple of turbo setups like this before on dakotas but cant recall where. I am having trouble picking out a the right turbo for this application. I know I will need something similar to a T-66. Does anyone know what automobiles from the factory use a turbo equivalent to this? I am wanting to do a bugdet setup so I dont want a 2000 dollars turbonetics turbo. I want a turbo that can boost at least 10# of boost on a 318 since the long intake pipe from the back of the truck to the front will lose 1-2#'s of boost. If any body has some turbo building tips for me that would be great.

The longer the pipes, the greater the turbo lag.

Uh...yeah, I already found that site, thats how I got the idea.
.boB: I realize there will be some turbo lag but that is why I need to find a quick boost turbo. All turbo systems will have some turbo lag. I was also looking at alternitive routes to put the turbo. Like maybe right at the crossover collector.

get the correct trimmmed turbo and there will be no lag.
it's not like there is a "universal" turbo out there and it has different lag on different applications.
sts has done their homework on this and has some pretty good applications out there.

Does anyone know of any turbos I could find in junk yard to fit my application. I was thinking about one from a cummins deisel but that would probbaly have too much lag. Which turbo do most of the 5.0 mustang single turbo guys use. That seems like it would work well for me.
Here
is a website where someone already did this but it is on a V-6

Ok, that's pretty cool and all but why not just put it next to the motor like normal?

Here are some reasons
1. No custom manifolds to be made.
2. No intercooler or oil cooler needed.
3. The turbo will run cooler
4. You can pop the hood and not see any anything.
5. Its different which I like to be.

There are a few books out there that should help you determine the right turbo size. Corky Bell is a name to look up. I borrowed it from the local library (a.k.a. free). You will not likely find a perfect match from a stock application. And you may spend more time and money getting one set up right.
You may want to talk to the STS guys for some help, or the guy from that picture you have there. The V-6 application turbo will most likely work for your application as long as it can flow the volume. The V-6 air intake to exhaust ratio should be very similar because it is the same engine less 2 cyliders.
I know this doesn't help you imediately which I am sure is what you are looking for. But in this situation the more knowledge you have the better your systam will be.

Im not going to do it imediatly. I am the kinda of person that like research everything before I do it. I you just go into something without anyplanning you will end up with something that doesnt work well and extra would be spent. So I am being pretty patient on this project. I just ordered that book so I will see what it has to say about it all.

I had done some research on a remote system for the 4.7 and a 273 cid. but I can't find the paper! Dammit.
I'll list the turbos here if I can find it.
BTW a garret T25 with an airflow housing of .66? will work in a twin turbo app.

i don't know if this would work but maybe one out of the old 300z that Nissan made. i think those aren't to hard to come across. i could be wrong thou.

search around, there's calculators out there that'll tell you what size you should use, but those are all based on traditionally mounted setups. could try getting in touch with STS directly and see how they determine their turbo sizes.
keep us posted on your layout & design. i'm planning one for my not so distant future.

Mopar 318,
I know it's not your original design, but in about 4 years, you are the first I've seen really bring it up here in any detail at all.
Nice work.
Just some questions, for a possible application on my 4.7.
You mentioned no custom manifolds, but it will take some custom plumbing.
I thought the turbo needed an oil line to it, to deal with the rpms and heat and friction that builds up. Would a quality sealed bearing work?

Yes, I would need an oil line. I would just tap into the oil pressure sender, run the lines to the back and install an external oil pump for the turbo. Then send the oil back to the front and dump it back through to the valve covers. I dont think there any turbos with sealed bearings. They would probally explode at the 100,000+ rpm speed and heat of the turbo.

Mopar318, why would you dump th oil return into the valve cover? you could put a bung on the oil pan above the normal fill level. i would think that would be neater and less likely to leak.

Hey mopar318 I couldn't find my spec sheet.
All it takes is a little research to find what you need.
Also don't forget that you need a scavenger pump to get the oil from the turbo back to the engine.

First off using a used turbo may be cheap in the beginning, but will cost lots more in the long run. Used turbos will(not could) have problems you can't see. Once it hitches on you, remote mount or not, it will cause lots of problems for you.
Feel like Smokey the bear offering safety tips.
