Discussion , Non-traditional Remote Mounted Turbo Systems

[toastyghost]

The first few posts are a little off topic, read on to get to the parts about remote turbo systems.

One great way to increase your performance is with 800-lb chrome wheels.
Seriously though here's a few ideas:
If you're going to have to custom jimmy-rig an intake you might as well make it a cold air intake instead of short ram. The performance gains are nominal with either but CAI is a little better because it extends to the wheel well or behind the headlight where it can get cool outside air instead of hot engine bay air.
The Pacesetter headers themselves are ok from what I've heard. The only complaints I've read about them were that the thermal coat peels and consequently performance gain starts degrading. That's not a major problem, just get Wal-mart paint stripper spray.. I forget exactly what it is, search the board for "wal-mart" or something to find the thread. Use the stripper to take the black coating off (cheap Pacesetters on NOPI) then spray your own high-temp thermal coating on them.
Someone was talking about they were running a 30 shot of nitrous with a cheap kit they found.. which would be ok except they were advancing their timing when they should have been retarding it. So ask that dude where he got his NAWZ kit (again use search to figure out who the fuck that is, I'd do it for you but I'm lazy). Then if you're going to use it I think they said retard ignition 1 degree.. this prevents the NAWZ from detonating and hurting the engine.
Hmm.. cheap performance...
Oh yeah, another thing you might want to look into is possibly making a "junkyard dog" turbo kit out of parts from salvage cars. The old Saab 900 T should have a lot of what you need to do this. You'll want to get the turbo itself, the coolant feed/return lines and the oil pan tap piece, and probably can use the downpipe and flange from the intake manifold. The flange will have to be broken and re-welded to a custom manifold. I was reading somewhere that a dude built a low-boost turbo kit good for maybe 80 hp (?) or so on a budget of about 600 bucks, by hitting his local salvage yards. Gains = 80 on stock internals, pretty damn sweet if you ask me.
That's all I can think of at the moment.
Good luck! Smoke dem damn Eclipses!!

Speaking of turbos, I heard that you need some sort of "approved" sticker on your turbo if it has been specially modified in any way in order to show that it is street legal, is this from the DOT or what? Or is it not even true? (I don't know turbo's) Anyone?

[1988starter]

Here is an idea for those of you who don't want to build a manifold

Interesting, however, I wouldn't think it would be as effective being that it's located where it's at. That, and hell, there goes 4 grand if you ever have something hit the bottem of your car, heh. Cool concept either way.

[1988starter]

I thought the same thing at first but look how high it is It would be hella hard to actually scrape it besides If it was me I wuls fabricate a small cage to protect it.

[Dutchboy]

I think that its a good idea if you cant fit a turbo under the hood!
PLus when your racing people on the street and they ask you how the heck your car is so fast and you pop the hood and show them that its just "stock" then theyll be very confused and taken by the shear power of your stock looking car and engine when theyre running a hopped up little civic or some pocket rocket.
I love Turbos!! good to see new ideas coming out!

[88accordhb]

manifold turbo is soo much better. it's closer to intake mani, you wont need all that long charger and ic piping and yah if you hit something,there goes the turbo.

very interesting tho

[smufguy]

in 2003 SCC featured that turbo system. It was proven to be worthwhile for trucks and suvs, but it was just too much work and only smaller turbos can be used. This is the same concept of the underhood turbos, but only with low boost and very unefficient method. They ran another article in the following month, critizing it.

[NXRacer]

i saw an installation of one of those on a camaro. I thought that a system like that wouldnt make boost for shit, but from what i understand, its pretty close to a manifold turbo and much easier to install. It is a lot more of a PITA to route pipes and stuff.

personally, i wouldnt want to worry about an expensive and somewhat fragile turbo getting crapped on all the time by being under the back of the car.

[danronian]

If I were to install one on a street car I would probably mike a protrusion in the trunk area so it would actually be at about the level of the trunk floor. It sounds like a great idea and all but I couldn't see having something like that hanging beneath your car, it seems like a great idea for a race car, but not a daily driver. I can't see them selling well to the normal person with a SUV or big pickup b/c can you imagine how fast that thing would get trashed going off-roading!

[b8er]

its a neat idea yes, its been out for awhile yes,its about the only way you'll get a turbo on a car with a small engine bay yes, but the downside i see is that a turbo runs off the exhaust gass' and heat from the engine, thats what actually turns the blades , as far as i know, and from what i can see , the farther away the turbo is from the exhaust manifold i worse its gonna perform or the more lag your going to have, and as we all know lag is the number 1 downfall for a turbo and for me i just wouldnt use it, there would be to much lag for and like some of you guys have said before if you do happen to scrap a rock or anything along those lines its pretty much toast

[NXRacer]

turbo's do not run off hot hot gasses, its the exhaust that turns the compressor wheel. The only problem i can see is that it'll take a longer time to spool the turbo since the exhaust has such a long time to go before it enters the turbo. Doing a muffler turbo would eliminate the need for an intercooler.

[smufguy]

turbo's do not run off hot hot gasses, its the exhaust that turns the compressor wheel.

its true, but the efficiency of the turbo does depend on exhaust gas temperature as their decline in temperatue with time reduces their velocity leading to bad spool time. Which u did mention after. Thermal efficiency is what all turbos fight to maintain because of their exposed exhaust housing. Thats why vendors sell wraps for turbo housing, mainly the exhaust housing to prevent heat loss and also reduce underhood temperatures via radiation. But like we all said, this set up in the scc and turbo mag blow, they might make pretty much the same power, but putting them on the graphs, and looking at their efficiency, it would not be the same or even preferable.

[b8er]

"but the efficiency of the turbo does depend on exhaust gas temperature as their decline in temperatue with time reduces their velocity leading to bad spool time"


this is what i was tring to say, not the gasses but the exhaust gas temperatrures, sorrry about that

[nismoracer99]

wut about rain?? wouldn't it get sucked up into the intake, and also water get on the turbo, making it corrode?

[Robs89LXi]

Actually, exhaust gasses travel very fast. Crank up your car, and see how long it takes to exit the tailpipe; it is almost instantaneous, and that is at idle. Heat does not matter too much either, as it is pressure differential accross a pump that tells it's efficiency. With the exhaust of the turbo now being a very short distance, you greatly reduce the exit pressure, thus requiring less inlet pressure to have the same efficiency. This is of course for the hot side, and when speaking of spool time, that is what you are concerned with. Conversely though, the opposite could be said for the cool side. With a much longer charge pipe, one would expect more back pressure on the compressor side of the turbo, thus hindering it's rotation, but this is where a properly sized turbo will help. Pressure in the charge pipe will be almost instantaneous also, especially if it is sized/routed correctly. Our cars have good low end torque, which would help the initial spooling process, then after that, the boost will do the rest. True, this will not be a great setup for instant boost from idle, but then again, who doesn't rev up their engine before dropping the clutch?

Yeah i was thinking rain and puddles too. Turbos are hot and i don't think cold water would be good on it. It would almost have to be a summer only ride, hot and dry. And a CAI filter every 1000 miles.

[g2driver]

Why do you all say a muffler and a tip? Wouldn't a tip if anything, restict exhaust flow?

[bobafett]

i doomed myself in this thread. my best 1/4 mile time IS a 16.6 lol

[Micah 89LXi]

why dont you be the first of us to get one of these
http://www.ststurbo.com/home its a remote mounted turbo....turbo is something like 200degrees cooler because its under the car at the back...they have a universal kit for $3k thing is i dont know if our cars can take 5psi boost stock...but this is an option i dont think anyone has discussed or considered..as i just found out about them..but just look at the dyno's and vids...they are insane..and even if it just made 200 bhp with 5psi of boost..do some engine beefing and you could take it up more...and even if not..200bhp for our cars would be nice and quick..oh yeah no need for a lot of the electronics in this kit...it takes out the need for a turbo timer and all that and its supposed to have almost no lag

[Micah 89LXi]

have you guys heard of or tried this?

yah ive seen it and they use liek in chevys the inner rear wheel well for the intake and tey give ya a cone filter with a filter "sock" it is im pressive being the pipe lengths on chevy's and trucks , makes me wonder with our 3 g's being very short in comparson that it might creaate some decent #'s

ive also heard that they make a injection of some sort to cool in intake air

[mr eff]

i don't see how running any amount of boost WOULDN'T require engine tuning... i want to believe, but it sounds too good to be true. "bolt on turbo" -- psh!!

[ICEMAN707]

i've been wondering of doing that for sometime. now that article i read on HCI magazine about it proves my theory that it works. but i wouldn't buy that kit. $4000??? yeah right. for that much money i can build it myself cheaper. just get a reground cam, i get to keep my dc header, apexi afc, 1g dsm turbo injectors, FPR, walbro pump or chevy camaro v8 fuel pump, msd coil and ignition box, ractive 3-core wires, ngk plugs, ball bearing turbo, custom piping with ceramic coating, b-series high-flow intake manifold (edelbrock victor x maybe), etc. etc.

i'm thinking of using two small twin turbos from the mitsu 3000gt vr4's, mazda rx7's, or nissan 300zx's for fast spool up and big boost.
