bigger pipping = more turbo lag. More velocity(smaller piping) = more spool, which in turn =

Since the downpipe is basically the exhaust there is no backpressure issues. My only concern with the kit is the distance the air needs to travel to and from the turbo. Good numbers, I've seen these kits on a number of different cars and they make good power. It's all up to the individual owner in the end!

The system is designed for that distance. I've never had an issue with the system or the "lag" everyone seems to think will happen with that distance.
The turbo kicks in the same time as a front mounted turbo.

They wouldn't be in business if the system didn't work. Innovation is the only way to stand out in the crowd and making the same and better power than everyone else can and for a cheaper price. Now you got a company that is going somewhere.

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

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!!!

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.

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.

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.

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.

I really like that gauge he has who makes it?

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.

This would be helpful. Not there yet.

Thanks!

Would be cool if they did a twin mid mount or a single mid mount kit.

I think with the way the turbo is designed it wouldn't work at peek performance if it was anywhere else..I could be wrong.

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