remote mount turbos

[sharkey]

ok i know some people here are gonna get into the whole remote mount turbos being a bad idea, but im just looking for some info, lets keep this civil and on topic.

im wondering what turbos are used for the remote mount setup. ive seen the sts kits, done lots of research, but cant find anywere what turbo they use, other then they say its a specialy designed turbo. i know some people have built their own remote mount setups.

basicly, i just wanna know what turbo(s) to use

Specially designed turbo? I know you need to have some sort of system to get that oil away from the turbo and back to the pan when the turbo sits at the same or lower level than the pan.

[sharkey]

yea i know about the scavenging pump to get the oil back. on the ststurbo.com site, they say they use specificaly designed turbos for remote mount applications.

i found the site of the guy that built the 3400 swapped z24 with remote mount turbo. ran 12.5 with alcohol injection and 10lb boost. he uses a t04b. before that he used a t3 from a volvo and proved it was to small for a 3400. so i guess that throws the whole "smaller exaust section" thing out the window for remote mounts.

[SHOoff]

I dont really undestand how they could be so specially designed. There's really not much to a turbocharger. Hell, with slight modification, a turbo can be made into a jet engine.

Probalby just one of those advertising gimmicks for "Blah Blah Blah, you HAVE to buy our kit so we can price gouge your ass"

I would say find a turbo that will be big enough for the engine, but yet quick enough to spool since you're going to have all that tubing.

[sharkey]

well the specificaly designed part im guessing they are using a turbo with a small hot section and a larger compressor side. but its now proven that you dont need that, that turbo z24 is using a t04b with a .63ar hot section, and thats not very small.

as for filling the long charge pipe, in reality, its not much more volume than a typical large intercooler. and the pipe acts like an intercooler itself, but has less pressure drop than a typical fmic.

im not sure exactly what im gonna do here. i have dual exaust on the car. i was tossing around the idea of twin remote mount but it seems like way to much design problems for me. i think ill just bring the exaust together just over the axle and into one turbo.

i just gotta find a turbo. i know volvo's do use a t3 in some years.

I've been thinking about doing the same thing. You know the benefits. Like you said, there is no intercooler restriction, so it's a wash? Longer pipe=more restriction, but no cooler=less restriction, so the same effect right? I just like the fact I wouldn't have to relocate the battery or mod the exhaust.

PM Kenton (89jyturbo) over on v6z24.com\. He's a very nice guy. He's the guy with the RMT 3400 that runs 12s. Just tell him what your doing and he should be able to suggest a properly sized turbo for remote mount.

another big thing with it is ease of install. a remote mount turbo kit can be peiced together without any special equipment. you can get a flange welded up to a pipe and clamp into nto your currect exaust. charge pipes can be made with silacone couplers and exaust tubing/bends. you dont even need a welder yourself (although its nice to do). and if you ever had to turn it back to stock, its quick to remove. building an underhood turbo setup is a lot harder, requires a lot more fabrication (custom headers and crossover pipe, exaust fabbing, ect.

the long charge pipe acts as an intercooler, but doesnt have any restriction.

think it can be done on a ciera? I'm gonna turbo my engine while I rebuild it next month.

Trying to find merits in a remote setup while using a traditional setup as a reference will get you into trouble real quick if you do not understand what you are saying...
A remote works because it works...the facts and I am been objective is compressing air in a 6-8' (I am been conservative) is a lot. This is automatic lag...throttle response and transient load suffers. There is NO intercooling effect...from a traditional stand point. The effect is the heat gases simply get cooler due to distance..., due to bends, etc, etc. Thermal trnasfer of heat by another medium in this context is so negligible you cannot call it intercooling Less pressure drop is debatable...but I guess it is not the object of the thread...lol!!
Regardless there is a place for remote setups...the niche is growing...Goodluck with the setup!!
BTW the turbo used by STS is not "special" it is just sized for the loss or inadequacies created by exhaust piping (depending on what side of the fence you are standing)...It does work...

Like nocutt said the turbo is no different. They use a small oil pump to suck the oil out of the turbo and place it back into the engine. This also benifits your engine because you get more oil compacity and it cool the oil off.

The company STS is about 25 min. away from my house and a lot of people around here run the steup. There is a Comaro around her putting 400-500 hp down to the wheels and there is also a twin remote mounted Mustang pushing in the 400-450 range. I dont remember the numbers but have personally looked at both cars and they were done quite nicely. Lots of the Toyota Tocomas around here also run the STS.

A while ago I remember reading a article in some hot rod mag. where they installed the STS on a 2003 or so Chevy silverado with the smaller v8. They got lower intake temps than with the stock setup, gas mileage went up like 5 mpg, and it dropped more than a second in the quater mile times.

I will do some digging and see if I can find the article. I believe they said what turbo they were using also.

Good luck getting it going

For me, I find it easier to build an under hood set-up than a remote mount, though I have not built a remote mount, simply becuase I feel it is no easier or time saving than going with an underhood set-up that will generally perform better. Ask 89jy, he will even tell you that he prefers conventional turbo set-up to his remote mount. The conventional set-up spools quicker, has less tubing, you don't have to worry about water splashing on the hot turbine housing causing it to crack, you don't have to worry about other objects hitting the turbo, filter, etc, period.

Myself, I have a very hard time finding space under cars to install neon tubes that are about 1" in diameter, I can't imagine trying to hang a 2" to 3" tube under there, and running back up to the front beside the exhaust will only help to heat the charge more.

89jy will be your best help in this build.

BTW the turbo is not "specially designed", the hot side is just smaller than would normally be used for the same application, due to the heat loss that happens between the engine and the rear of the car.
If you read about turbine theory and application, you'll never want to run a remote mount set-up.

You don't need any special header for a conventional turbo either, but headers like in any application will only help, even in a remote mount set-up.

If you are lying to yourself saying that a remote mount requires less speciallized tools or is easier, go ahead, but the reality is, it's no easier, and still requires the same tools and know-how.

BTW I have considered a remote mount for my '98 Malibu, but when I sat down and started planning it out, the conventional seemed easier, and I know it will work better. I'll probably have one custom manifold, because of the way I want to build my set-up, if I did it a bit differently, I probably wouldn't even need a custom rear manifold.

I first saw this for the firebirds/camaros. I've seen the superchargers with the water intercoolers. I can't believe they make these turbos due to lack of space.

OK! Why don't my quotes get seperated and highlighted???
