STS Turbo Kit
 

Hey Guys,

Came across this in my random internet shenanigans. I think I saw that someone posted about the idea of a remote turbo kit and even had done one on their own a while ago. Since I didn't see the STS kit in the Turbo Kit sticky, I figured I'd share.

Aside from weight distribution and novelty, what are the benefits? Seems like it would add complexity and material, which are negative attributes, in my opinion.

STS is showing their rear turbo BRZ at SEMA. I'll see if @Chris@Phastek and I can get them to talk about this kit and the benefits while we are here

The most notable benefit I see is the significant under hood heat reduction and probably a cooler running turbo though with a charge pipe that long I imagine throttle response to be pretty much non existent and the overall extra weight added to the car makes the idea of rear mount turbo questionable

One uneven road and POW..

That uneven road would hit your front bumper, under tray, oil pan and differential before it hit the turbo.

Not included in the OP but it was mentioned in thread STS is later doing twin turbo too.

This looks like a nice synopsis:
+Intercooler optional.

A couple of owners are SC + TC. My guess is this will be a good option to keep an unclutter engine bay.

Rear mount is something Ive always considered more for cars with big v8's stuffed under the hood that don't have room for FI. Luckily we don't have that problem.

I like the idea, but in my opinion, it has no practical value. Laggy turbo? Aint nobody got time for that.

when all you have is a hammer, everything looks like a nail...

this is a solution looking for a problem. sts builds rear mount kits for cars that can fit a turbo where it belongs. why?

I never understood the appeal of these systems. Piping that long will make the turbo take forever to spool. Just adds a bunch of extra complexity and weight.

Somebody should release a turbo kit that would utilize a V-mount setup.

Interesting design

I've always understood these kits to be good for 2 problems:

1. Cramped engine bay
2. Budget

And if you're only 1 for 2 ... you should save up.

HOWEVER

If you just want a street car that goes whoosh and is fast... the details probably won't bother you and this kit will be fine.

Serious about motorsports / racing? You're probably going to be looking elsewhere.

A rear mount is a design compromise just like choosing between a low mount (AVO Style) or a high mount (FullBlown).

I would really like to experience one of these first hand before passing judgement like most people seem to do.

And I agree with empower-auto, since most people use these cars on the street for fun Im sure this would actually satisfy lots of people. Accept that its harder to brag about at the local show.

Well there are quite a few enthusiasts that feel different is better and the more "unique" your mods are the better they are. So I'm sure if it works they will have plenty of buyers to stay in business.

I just don't like their seemingly thrown together add ons (willwood, verdestein, etc)

Have the people complaining about lag experienced and measured it in real life? Turbos move air pretty darn quickly. A T3/T4 can move like 500cfm at full boost. To fill a 12 foot x 3" diameter charge pipe takes about .03 seconds at 500cfm. Certainly more time than a short charge pipe confined to an engine bay, but I can't say I'd be unhappy with that response time. Of course, there may be some variables I'm missing. This was just a quick calculation on my lunch break.

my issue with it isn't just that it's inferior in many ways as previously mentioned, but that said compromises are completely unnecessary on this platform. we have room to mount it where it belongs. it's rear-mount because they only make rear-mount kits, not because that's the way it needs to be.

i mean really, when was the last time an oem put a turbo where the muffler goes? there's a reason.

Also if you were to stretch out the piping from the typical intercooler you end up with a pretty significant distance as well, so considering the full distance from the rear isn't very fair. Some people claim this pipe under the car is enough cooling to no longer need the intercooler, so thats nice I guess.

However, it isn't just as simple as the intake charge pipe. You also have to deal with less optimal exhaust due to being at the end vs right off the header. (things like heat, pulses, etc) So, the turbo won't spool as fast. Its not just the time to fill the intake piping. Be prepared to not only deal with intake pipe leaks now but also exhaust leaks due to a system that typically wasn't designed to be pressurized now being pressurized.

Additionally, unless you run an oiless turbo, now you have to run oil lines to the rear.

So basically there are a lot of tradeoffs for essentially the single benefit of not having to change out the header. Hurray.

Rear mount setups have their place. Unless this kit is somehow cheaper than the AVO, that place remains with the v8 world. If it is cheaper, then idk, maybe some people could find it worth it.

Good points, I hadn't really thought about exhaust pulses and heat lost on that end. I agree there's not really any reason to do it on these cars other than perhaps weight distribution or stealthy street racing.

:beatingadeadhorse:

For a company that thinks they own the patent for rear mount turbo(s) in any automobile... EVER.
They are over a year late on this chassis.
@Roadstercycle Should sue file a suit. :lol:

On another note, while not for me. Some people would be quite surprised with the actual lag in a similar system.

The STS turbo for our platform has been around since over a year ago...

^^ yup

Suggesting some equivalent effectiveness of the cooling potential for a volume of air moving in a standard intercooler to the volume of air moving in a length of charge pipe is pretty absurd. First, the pipe will create more static pressure (e.g., resistance) than the intercooler and cause the turbo compressor to work harder and heat up faster. Since the air velocity in an intercooler plenum is much slower than that in a typical charge pipe, it has cools faster. With fins and high velocity air striking perpendicular to the intercooler it further dwarfs any comparison with a long pipe under the chassis. I don't know what the delta comparison would be, but my guess is an order of magnitude difference. BTW, I am responding to an earlier post that I didn't quote.

I've heard an STS kit strapped to the rear of a 350Z. Everything else aside, it sounds like you're following behind a jet.

It's certainly a great deal of nonsensical fun. :D

I need more info on this.
when will it be available and what's the price?
can you guys start a formal thread with info on this kit so that we can have it added to the turbo kit sticky?

my biggest and probably only concern with this is how close to the ground the intake is.

Yes, even the youtube videos it does sound pretty incredible

I emailed them last night, if I get any updates i'll post them in this thread.

"Our full bolt on kit comes with vehicle specific ceramic coated pipes, a vehicle specific STS remote mount turbo sized out for your horse power and torque goals, STS intercooler, proprietary oiling system, Turbo smart waste gate and blow off valve, STS wiring harness, all the vehicle specific lines and fittings, optional tuning package and a full step by step instruction manual. We also offer additional system upgrades such as ball bearing turbo, electronic boost controller, heat shield, etc. Usually we see a 20-25 hp increase per pound of boost and a 10-15% mpg increase. I think that our turbo system would work really well on your BRZ and make a huge horse power difference. The great thing about our turbo system is that you are gaining performance and you are keeping the drivability of the vehicle. The base turbo kit for your BRZ/FRS will be around $4495-$5995 depending on options and if you want the intercooled kit and tuning package. Let me know if there is anything else I can help you with. Thank you.

Popular optional components and upgrades include:
STS Turbo Dual Stage Boost Controller $175 – Allows for a low and high boost setting. Allows you to change low/high boost from inside the vehicle and is fully adjustable
STS Turbo Water Methanol Injection System $499 – Arms with the electronic boost controller, lowers air intake temperatures, prevents detonation, strongly recommended for higher boost applications
STS Turbo Turbine Jackets $175 – Heat blanket that covers the exhaust housing of the turbo. Allows the turbo to reach operating temperature faster, increases spool up time, keeps turbo heat away from the vehicle
STS Turbocharger Ball Bearing Upgrade $600 – Decrease spool up time due to less friction on internal components, longer life and better throttle response
STS Turbocharger Compressor Wheel Upgrade $300 – Increased hp per pound of boost, better efficiency , allows for high boost pressure, ask for horse power rating
STS Turbo Wide Band/Boost Gauge set $600 – Allows you to watch boost levels and AFR, Strongly recommended on any application."

Good for roll-racing... *shrug*

why in the world would you use a turbo jacket with this setup?
it's so far away from the engine.

This Kit seems very expensive for not having a turbo manifold.
Also how are they running the oil to the turbo?

I wonder that to a few have already said it but I have been in an STS Rear Mount WS6 and it was not slow to build boost in fact it had boost by 2800rpm. A way to make this happen quickly was to decrease the charge pipe size. However that car did not see that done as the owner went to a front mount later on to make more power with a bigger turbo. However he really liked the setup but at some point you do run out of room for bigger turbos. But then this was a V8 setup not an FR-S 2.0L.

These systems do have their pitfalls and its nothing major.
1) if you blow a coupler it can be harder to get to but that's not uncommon for turbo cars.
2) Providing oil to the turbo can be an issue but STS really got that down years ago when they started these kits.

These kits are what you want to go with when you want stealth. If I wanted to go completely hidden this would be my choice but I prefer the Supercharger idea I have.


STS makes a decent product, is it perfect no. But then I don't know one shop that has a perfect product its all just a matter of opinion and we all have an opinion.

from http://www.ptpturboblankets.com/faqs.php

I'm an absolute Forced Induction novice but wouldn't it be easier to twin charge with this kit since it won't clutter the engine bay? I would assume the Innovate supercharger would work with the STS turbo no?

So wtf isnt there more info on this here?

Im just gonna make my own if i dont see info soon. Pretty simple to replicate lol.

just google search roadstercycle. STS basically stole his idea.

bye now

not sure what ur eluding to... sts does kits for all kinds of cars but i believe (could be wrong) roadster finished his first for the brz/frs. please tell me ur not one of those sts-has-rear-turbo-patent guys.
