STS 370Z Single Turbo System

tower74

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. Old age=memory loss

kosstick

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 . 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.

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

tower74

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?

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?

pyrrhus17

Has anybody with a sts system tracked their car and what were their experiences ?

tower74

I've put about 2500 miles on mine. Other than some tuning issues no true problems. Still pulls like a SOB.

SharpByCoop

This would be helpful. Not there yet.

Thanks!

Jim

I meant taking the car to a track and running her for several laps ,pushing hard .There is a consensus that the 370z with FI is not trackable 9 do to temp issues , brake overheating etc Thanks . This is something sts should really do they would get alot of buisness if you could mod and track this car . I think its one of the main reasons people are dumping the 370z for other cars IMHO.

How is the power under 3k RPM when you hit the gas? Similar to stock? Less or more power?
