Let's talk remote mounted turbos...

[$100T2]

Has anyone ever thought of doing this with an NA? I know that it would be far easier to plumb in a remote mounted turbo than to do what other guys (you know who) did...

As far as I know, you need a turbo, an oil cooler and line for it and a pump, unless you somehow plan on running it to the engine oil. Let's discuss the logistics, come up with a plan, and then someone, probably me, will be the guinea pig to try it out.

Problem solving time, people. Let's rock!

Relocate it to a storage bin? :dunno:









:rofl:

For real though, I like where this is going. Hopefully there will be some good info put in here.

[$100T2]

Relocate it to a storage bin? :dunno:


Actually, that's not a bad idea. If you cut out the storage bin and weld in a box, reversing it so instead of open to the car, it's open to the undercarriage, that would give you a lot of room. Take out the passenger bin, and the turbo would be conveniently located, too.

Damn I'm good. Could you duct pipes/air for an intercooler back there? :p

[$100T2]

Now you're pushing it.

[My5ABaby]

Small intercooler? With alky or water injection? :dunno:

I always thought one of the advantages of remote mounting is the long charge tubes serve as intercoolers themselves ;)

So a small intercooler would be good... :D

[85rx-7gsl-se]

^ Maybe a modified TII top mount?

[$100T2]

If you put some cooling fins on the charge pipe, it could be one long intercooler. Drawback: Road debris. Maybe run the charge pipe inside a larger pipe with directed airflow through it to surround the charge pipe?

[djmtsu]

Good luck finding a place under the FC to remote mount a turbo. You can put one where one of the mufflers sit, but that would mean a lot of long tubing. You could put one in the front bumper somehow, and melt the front end to the ground.

Just another note. The stock turbo is too puny to deal with a big FMIC, much less all the tubing RMing it would create. What turbo would you remote mount, that would fit, and not lag like hell?

Which is the point of this thread. We're going to do all the theoretical stuff now and work it out, then try it.

[Rotary_Rocket_87]

STS Turbos makes remote kits for alot of vehicles. They could probably figure this out with little difficulty.

[85rx-7gsl-se]

^True, but I think he is wanting to go low budget on it :p

What's the fun in that? Plus, if we figure it out and do a how-to thread on it, other people can duplicate it.

[Rotary_Rocket_87]

Sorry, what I was trying to imply is that the OP could talk to someone there and get some advice.

[MaczPayne]

Unless you can find a way to retain all the thermal energy contained in the exhaust, you'll lose it as heat through the ultra-long manifold leading to the remote-mounted turbo. Not a very efficient design IMO.

Hmmm. If it's going to be run from the bin area then I would think you could insulate the intercooler piping with the exhaust piping somehow.

I realize the design isn't as efficient as an underhood mounted turbo, but what I'm looking for is a way to add a turbo to an NA without all the underhood work required. I'm not looking to make huge power, I'm looking to run 5 -7 pounds of boost to give the car more pep.

[firzen]

If you put it in the bin area, it's gonna get crazy hot in there- and you'll have to cut through a fair amount of metal...

If my memory serves, I've seen this kind of mod done on an Infiniti sedan somewhere on the nicoforums. I'll look through there and maybe find the link to that thread... But IIRC, it was a ginormous turbo and the piping seemed too long and unnecessary.

Gotcha. So what's your plan so far? The turbine section will have to mate with the exhaust flow somehow, and that requires some fabrication. I have an image in my head right now, but I'm not sure if it's the same as yours.

[Max777]

one of the points of the remote turbo setup is the fact that you DONT need an intercooler!

The length of the pressure side pipe may seem like a lot, but in reality it is actually SHORTER than a FMIC setup, AND there is no need for one.

Second, there is no real need for almost ANY exhaust, you can run a header, an straight pipe to the turbo, and then a short straight pipe right out and to the atmoshpere.

The fintake pipe will most likely be the big problem, and you will need to mount it out of the way of water, which probably means putting it inside?

From what I remember reading on some thread, the oil cooling is also done separately in some cases.

That's about all I learned about it. Sounded stupid to me at first, then I read some thread about how it really isnt as bad as you would think, and while Im enlightened, im still never considering it...


I think a comprex supercharger would be cooler.

[Boostmaniac]

I think a comprex supercharger would be cooler.

Yes, not to mention more sensible if all you are looking for is pep vs. big power.

[Max777]

lol

I take it you read "That" too, huh? :D

[TehMonkay]

Why on an FC?

[Phoenix7]

1. where would it be mounted? THe bin doesn't seem right to me. And there isn't much room in the exhaust system. Too far back and it's stupid close to the fuel tanks too far forward and it's like mounting a stock TII turbo.

2. piping and custom work. Where is there enough room to mount the turbo, piping, wastegate, etc., etc.?


3. Bad weather. Would the turbo or HOT pipes be damaged by COLD water on the ground after a storm/rain? Imagine full boost into a puddle of cold water.

4. Oil/water cooling? Where will the reservoirs be (bins?)? oil/water pumps would be necessary to plumb in it's own cooling system. Unless you use the stock oiling system (will there be enough pressure in the system to make it work?).


I've followed this thread since the beginning but didn't post since I'm not a fan of these setups.

"Actual photo of how hot a traditional front-mounted turbo can get. You do not want this near critical plastic and electrical components in the engine bay, or mounted under or near your feet causing significant driver and passenger discomfort."

SO they decided to install them next to the plastic vette fuel tanks??


Where, under the FC, can you set this up:

[Max777]

i like how both pics have solid axle cars, and I also totally agree with you, phoenix, (but dont let it get to your head.) :D

[Phoenix7]

they have a 350Z that claims a 120hp increase but no setup pics. :dunno:

[Ender]

Ok seriously, if you mount the turbo even just 4 feet from the block do you realize how wicked your lag will be?

[Phoenix7]

no. I haven't thought about lag yet. Tell me more.

[AwakenNoMore]

i think we're all think in the wrong direction, instead of far back what about far forward, as in under the passenger side headlight or something?

[My5ABaby]

I'd see heat being an issue there. It'd have to be well insulated or stuff is going to melt. However, I suppose it's a possibility given enough room.

Ok seriously, if you mount the turbo even just 4 feet from the block do you realize how wicked your lag will be?
I'd be OK with lag if it meant I would have a turbo on my car. A 4 port is near the same as a 6 port low end without boost and even with a laggy turbo the turbo-ed car would still be faster.

[classicauto]

I think lag could be negated with a properly sized turbine housing for the smaller amount of heat.

In reality though, lag even on giant T6 turbo's is a moot point. Anyone who's going to flog the car isn't going to do so from 1800rpm - you're going to floor the fuckign nuts off it.

IMHO though, there's way too much room in the engine bay to consider re-engineering the turbo system for this type of mounting.

[Phoenix7]

I can see why they'd want to keep that cramped engine bay away from a turbo but the FC hs plenty of room. Either in the stock position or with a custom manifold that moves the turbo forward.

[Ender]

When I was still using a Thrush Turbo muffler as a midpipe on my otherwise open 2.5" exhaust (w/ two mufflers after a y-pipe) I was able to creep to 12psi boost for a brief moment, but then it'd plummet down to 5-6psi, even in the high gears. That Thrush pos reduces to about 1.75" inside, yet I was able to hit some wicked boost (but only for a moment) before all that air got compressed into the three feet of pipe before the restriction point. I don't doubt this would work similarly, but with even worse effects. First, when you romp on the throttle you won't boost quickly, your basically NA motor will be fighting to cram a bunch of air to drive a turbine (which will certainly resist, and more so as it spins faster). So then, once it's actually spooling, the turbo will have to play the same game to get the compressed intake charge into the chambers. I would bet that such a system may not benefit you AT ALL in first or second gear, and maybe minimally in third. And when you shift, your compressed intake charge will have to be vented and the only thing you'll have going for you is the turbo is at least still halfway spooled up. I'd be curious to see this done just for kicks, but I don't see any real practicality in it. Compared with a standard under-hood turbo setup, you'd almost certainly sacrifice power gains, you'd fight things like lag, it could end up costing more than if you'd just used an intercooler (look at all the labor and piping it takes to do this)...

[dregg100]

have you been alseep for the past few years? have you not seen the remote mount turbo kits companies are producing and how rediculously fast they spool. remember, rotary's put out just as much exhaust as most 6 cylinders and some v-8s. also remember that the cooler air gets the more dense it becomes. so actually you are wrong in saying it "wont make boost in 1st or 2nd" haha. thats why long runner manifolds(underhood) spool faster that shorty's or that shitty cast iron block of a stocker you are running.

i think this would be fantastic and have been wondering why no one has tried it yet. good luck

[Ender]

No, I just haven't done research, and this is the first time I've heard of this in a serious context.
