I was just wanting to know if anybody here knows anything about remote mount turbos. Ive been taking to a shop owner who does a ton of work and really good work and we've been discusing putting a remote mount turbo system on my car. If anybody knows anything please let me know. thanks

What do you mean by remote mount?

I believe he is referring to the "Squires" turbo type arrangement.
Put the turbo back were the muffler lives. Yeh no spool up issue there baby

 

[the driver]

hmmm interesting, I've never seen a setup like that before, time to research...

It's popular on cars with cramped engine bays.

 

[toykilla]

that does not seem efficient.. your will be piping exhaust back to the turbo, then piping the intake all the way from the back of the car? Take a look at the APS single setup.. It puts the turbo right after the headers... Best single idea i have seen yet.

 

[redlinez33]

yes the setup is where the turbo is mounted in the rear of the car, I dont really know that much about them, but from what ive been told the 350z engine bay is cramped thats why this setup has came into play. The person that is going to do the work has told me some hp numbers that are pretty good.. they said around 360 rwhp give or take.. on i beleive 7psi. The kit is comming from squires turbo systems. They dont make a kit for the 350, so the guy which is a sts dealer and incredible mechanic is going to be i guess building me a kit.

 

[toykilla]

there have been plenty of creative ways to stuff a single or two turbos into the engine bay. I think puting a turbo at the back of the car is just not a good idea by any means.

yes the engine bay is tight, but greddy, power enterprise, top secret, aps, turbonetics, JWT, and many more companies have had no problems stuffing snails in the cracks.

 

[redlinez33]

Well Ill go a head and let you know that i would rather have a APS, Greddy or any other turbo kits, but I can get this done a lot cheaper so why not...and i am not going to do it if it isnt going to be safe. What questions would you be asking if you were me?

 

[studybuddy]

Is he making you a custom manifold too?

doesnt sound like this is using a manifold. From my understanding the turbo is giong to be attached to the exhaust pipe somewhere near the back of the car. Then you will have to double the piping ALL the way back to the engine.. This extremely inefficient. You are going to loose some flow by doing that.

How much are you paying for this setup? I would be asking the guy if he really knows what he is doing. Sounds like he just doesnt want to put the turbo where it belongs (in the engine bay) If you are paying anywhere under 4-5k then i would be weary of this guy. But for a little over 5k you can have the safety of the name Greddy.

 

[redlinez33]

I am going to be paying under 4 for everything including install, The guy does good work and has done a lot of incredible work like custom stuff from headers to manifolds... the guy did the a single turbo conversion on one of my friends supra tt and the work looks good. I dont think he would be telling me to do this if its a bad idea. but who know....i dont yet.

 

[toykilla]

I am just skeptical, but if it works out i want to know! Post pics and details when it happens.

I'm sure it will work , and the peak rwhp could be good as well.
Howver; the boost lag and shape of the TQ curve will suck.
But for <4k installed , go for it. It's a "budget" arrangement, far from perfomance optimum , but cheap. Definately on the ghetto side of the curve.

 

[redlinez33]

Iam going to talk to the guy whos doing the work this afternoon. hopefully i will understand a little more about whats going to be goin on, and what ever i find out ill post...

Yes I know a fair amount about this turbo design and position, in short don't bother. This turbo approach has many design flaws, not worth the effort for such a poor result imho, invest a little more into the project and then have the turbo conversion performed the smart way which will deliver optimum results.

[redlinez33]

what exactly is so bad about doing it this way...Ive heard people say its not good but havent really heard a anwser.

 

[Nis350ZTT]

Well, it will be mounted at the rear of the car under it, not very safe imo. Lag will be pretty bad (turbo won't start spooling before 3500rpms I imagine). Like g3po said, TQ curve will be bad. Might as well save a little more and get a Turbonetics. Or maybe even consider Vortech (I consider Vortech the most potent s/c kit for the 350Z, just m.o. though).

1) Very inefficient use of the exhaust gas energy, the exhaust gas temp is much lower by the time it reaches the rear of the car where the turbocharger is mounted, I've tried this approach on a number of different cars over the last 20 years, the result is always the same, very poor.

2) It's very easy for the turbocharger to be stolen from the rear of the car.

3) The discharge air ducting is at least 10 to 12 feet from the inlet manifold, the pressure drop is very ugly hence poor engine response and power.

4) The air cleaner element is in a very vulnerable position in terms of dust, water and, and other road debris.

5) The turbos lubricating oil has to be plumbed from the engine and then pumped back to the engine in most instances, a lot of unnecessary plumbing to have floating around under the car.

There are more good engineering reasons though these are the main reasons that come to mind, not a good approach to turbocharging imho, and I've had practical experience with this approach. :headshake:

& if ya don't believe the man from APS, who ya gonna believe?...

Your mech. might be a good guy & all, but...not everyone's an engineer. & since you're behind the wheel of a highly engineered vehicle, why fall down at the finish line?...

Wait, save, do the right thing....& you won't be disappointed. The comapnies who've developed F/I upgrades for the Z33 have all done their homework...some better than others...(APS)...What's the point of a generic, untested system, which, by its very design is inefficient?...

The thing you can't put a price on is how annoying it is to have something done & not turn out right...
