STS 370Z Single Turbo System
 

This is the STS Turbo 370Z thread. Here we will provide information, post pictures, videos, updates and answer any questions that you may have. We hope you enjoy!

The new STS Turbo 370Z turbocharger system has been over 1 year in development and testing. We are proud to release what we believe to be the best forced induction product for the Nissan 370Z.

Our large front mount dual-core intercooler fits behind the stock front end with NO modification to any of the structural components of the vehicle.

The engine compartment is left clean, free of clutter and requires NO modification. Any future maintenance or repairs will require no more work than a stock Z. Dual 52mm Turbosmart Race Port blow valves are standard in every 370Z kit.

All of the exhaust components come standard with an extreme high-temp, ceramic heat barrier coating. The intake pipes are also coated with a durable high-luster ceramic coating. Exhaust tips are a stainless steel dual wall design, also standard. Notice how our piping follows the factory exhaust path so you know there is nothing on the STS kit lower than any factory components. In fact, the turbo assembly is harder to see from the rear of the car than the factory muffler!

To maintain the dual exhaust we have used the wastegate dump as the driver side exhaust. Also, notice the large filter shield which allows plenty of airflow while keeping the air filter out of the elements. Just loosen a few bolts to remove the shield and service the air filter.

This customer wanted our dual resonator upgrade to quiet the exhaust note. The resonators are a high quality polished stainless steel piece modified to be a bolt-on installation with our system. The resonators have a solid ceramic core so there is NO chance of a resonator packing failure.

You are not required to buy headers, exhaust, air intake or any other aftermarket components to complete the installation. The STS system does not require you to modify any of the factory emissions equipment. All of our HP numbers are from cars with completely stock exhaust manifolds and cats.

This car was a bone stock 2010 370Z Nismo. This car had a baseline of 272.58 RWHP & 229 RWTQ. We have seen the stock Nismo cars go as high as 295 RWHP which would only add to our boosted numbers.

At only 5.5psi we are getting over 400 rwhp. That’s 125 more than stock! With methanol injection you can safely make over 500rwhp! We also offer numerous turbo upgrades that will support up to 950chp! (Dyno graphs are in video below)

The average install time for this kit is between 8 & 12 hours depending on options. The ONLY modifications to the vehicle is drilling a small hole for a clamp and cutting a small ear off the plastic radiator support to allow an intake pipe to be installed. If you can install a cat back exhaust and a cold air intake, then you can install this kit by following the detailed full-color instruction manual.

now this is what i like to see. this thread will be blowing up soon with questions i'm sure. there are so many people interested in this kit, but up unitl now there has been so little actual info.

looks like some vendors do like to come support their customers

Subd... any idea on pricing?

I drive my Z in the winter as a DD. I wash my Z a lot at the touch less car wash which includes a bottom blast to the under carriage. Would this be ok to do with your turbo kit?


----
Edit:
It looks like I would have to fab something to protect against direct water blasts. However, I'm still interested in what you recommend.

Mod list? Does it cost extra to have everything coated with resonators? If it does cost extra, what does it cost?

I really like that gauge he has who makes it?

Anyone try this with Fast Intention Long Tube Headers yet?






DAN

someone did check the other STS thread

What about fuel system and ecu management? Does this comes with the kit also?

this kit sounds so so much better with the new exhaust setup, can't wait to get the new exhaust installed, spring can't come soon enough!

I was gonna go this route but STs informed me that leaving the stock cat in hold heat better and spools the turbo quicker

That's why they stick with 2.25" exhaust piping.

Can this set up be used for track use without fear of overheating the car? From what I know all the other FI options can't be tracked for a longer period of time without having the cooling system seriously modefied

An oil cooler is always recommended for an under-the-hood turbo system as oil temperatures rise quickly with the VVEL system. It's not needed with the STS kit though.

I believe the hottest day I've ran mine was in the mid 80's...my oil temp never went above 220 and that was driving the hell out of it for about an hour and a half. Of course it wasn't a constant boost fest but it was a good amount.

This was not on a track but on the highway!!!

^ do you get quite a bit of lag with the turbo being that far away?

No...don't believe everything you read. If look at the pics you will the exhaust runs into the Turbo, so everytime you hitting the gas it's spooling the turbo.

Any increased risk of hydrolocking with the filter being below the body of the car?

No. The air filter has a water sock on it. I've taken through car washes and drove it in the rain. Just every once in while it needs to be cleaned.

Oh wow that's very surprising. I definitely getting one installed as soon as my warranty is up then, better get started on saving.

Just don't make the mistake I made and buy it at the installers shop (buy it online). Taxes killed me...about 800-900$ in taxes. Otherwise they are a very good, inexpensive turbo. I paid about $8000 for the whole kit....that's with a boost controller, meth injection( they threw that in for buying the boost controller), ball bearing upgrade & ceramic coated.

@ STS/ Vernon or Marc....Could you please send me the info on the Uprev tune that comes with these kits. I have emailed you but still waiting on a response. I'm going to be taking my car to have it tuned at another shop and he needs the info...trying to fix my hot start issues. Thanks.

nah, just by looking at the pipings and seeing how far the charged air has to travel to the engine i would assume there would be major lag till it actually reaches the engine.

congrats on the kit though!

Thanks...had it since Sept. love it.:tiphat:
It's not going to beat a twin off the line because it is a single but trust me I thought the same thing until the first time i hit the gas.

lag from piping distance is negated by the cooler, denser air charge created from the remote turbo location. lag is virtually undetectable. plus our engines run such high compression from the factory, it makes the typical "turbo lag" hard to detect anyways

At what RPM does boost start and what RPM does it hit max boost?

I want to say at about 3grand and somewhere around 6grand. Its been over 3 weeks sincse I last drove her. So I could be wrong. :icon14:Old age=memory loss

you are 7 speed right? How many miles on it and hows the transmission holding up

Thank you sir, Exactly what I was looking for :tup:. The system is looking better and better.

Yes sir is the 7AT ....the only issue I have is the uprev the tranny will do if it's cold outside but was told that its in the tune. One existing problem before the turbo was that in manual side,when I wouldn't downshift it would clunk going from 3rd to 2nd..doesn't do it any other time and not all the time.
11,500 on the car....about 2,500 with the turbo.

I'm impressed. At first blush, I was like: "WTF???!! Look at how long the flappin' intake is....! Boost will come on somewhere between 2 seconds or two blocks of target...." After watching the vid, and looking closely at the chart, it's pretty damn good. It makes 300whp at 4400 RPM. Helloooo!! Now who's complaining??

The whole thing appears to smack of home-built mentality, but, truth is, it's out-of-the box thinking. America is good at that. :)

I wish the purported pricing was less ($8000?), but from all appearances the labor savings and lack of other hardware needs makes this a value.

Good for them. I will be looking forward to some other build threads and performance trials. I ain't looking back, but this ought to increase attendance in here.

Coop

You've got to remember...I bought a lot of extras ...so everyone else's total could be about a grand or more less.
Just found the picture of my receipt ...with the turbo ceramic coating,and ball bearing upgrade and shipped was $6950.

Boost and TQ does come on alot sooner then I thought it would, Im impressed. Only few things I wonder is...injectors, fuel pump, and who's base tune? Also on the high boost setting they stop at 7k and TQ falls off hard...lil weird

I'm trying to remember...but it should come with new injectors, plugs and fuel pump in that price...it dropping off a 7g my guess is that's when he let off the gas.

Thanks for all the questions and general interest guys! I will try to get on here at least a few times a week with answers and updates.

All of the components in our kit are designed and tested in all kinds of weather. The STS filter shield was designed to protect the filter during all typical driving conditions. A undercarriage car wash can cause problems with all types of aftermarket modifications. If the filters are exposed, regardless of location, they will be susceptible to water being sprayed directly at them. We do not consider this to be a “typical driving condition”. It is really a case of knowing your car. If you have an aftermarket/custom air intake that is exposed through undercarriage or through the radiator opening you know not to spray water directly at it. The shield should protect the filter from the undercarriage spray and deflect most of the water, however, there is a LOT of pressure and quantity of water that comes out of those undercarriage sprayers so we recommend that you stop the car when the spray hits the rear tires so that you are not spraying water & soap directly at the filter shield.

We are currently not in any stage of development on a twin turbo system. We offer numerous upgrades that will give our customers the ability to meet/exceed their HP goals with the single turbo setup. If there is a real demand for a twin turbo system we would be more than happy to develop a kit that would allow you to upgrade from the single system to the twin. Anyone interested in shipping their car to STS? :D

On that note we are also looking for an auto transmission car for an update.

All of the STS turbo systems are designed and tested on completely stock vehicles. We take pride in the fact that there are NO additional modifications or parts needed to complete the install or to achieve your HP goals. We custom build all of our turbo systems based on the customers goals.

The ceramic coating is standard on all of the STS turbo systems. The resonators are optional. I will modify the first post so that it includes some of our pricing on the base kit and some of the optional upgrades.

The gauge is a PLX Devices DM-100 with the vacuum/boost & AFR modules. We carry the PLX gauge setups in house and install them all the time. It’s probably one of the cleanest gauge setups out there. We modified a autometer universal gauge cup to house both the gauge and our methanol lights.

We sell the kit in "Tuner" form for guys who have access to their own tuning and fuel system upgrades. We also offer our tuning package which comes with an Uprev cable, injectors, fuel pump with complete install kit & an STS base tune.

The radiator still has adequate airflow even with the STS intercooler. We have not had any issues with coolant temp on the street or on the dyno.

As most people know by now the 370Z is susceptible to very high oil temperatures when driven hard in stock form. We carry the Z1 Motorsports oil cooler kit in house and recommend on all high performance 370z applications. It fits perfectly with the STS intercooler and intake pipes. The kit consists of a 34 row Setrab core, oil filter adapter plate and large application specific lines for a clean, easy install.

What is the exhaust piping diameter? I was wondering how beneficial is it to increase the size of the exhaust piping between the turbo and engine?
