STS Systems

motoextreme · 11-02-2009, 08:37 PM

Anyone heard of STS systems and how functional they are? I did a search but nothing came up on the forum however I did find their site.

The idea has some merit to it, put the turbo's under the rear bumper and keep the heat away from the motor but seems a bit out of the norm to me, I mean exhausts are pretty air tight for the most part but I'd have to think it would lose some power from the joints?

There was a Vette on the show I was watching a week or so ago, car was crazy fast and the system is supposed to be in the $5-6K range so its reasonable. Lists a 350Z as an application so I have to assume they will have something for a 370 before too long.

There has been some discussion on these before, with some people saying rear-mounted turbo systems are terrible, some saying they are wonderful, blah blah...

The theory is that a rear-mounted option decreases installation cost and removes the ambient heat generation of the engine bay. They offer a kit for the non-NR motor 350Z, and I believe it is a single turbo solution.

One thing is for sure, they sound sick as hell with the turbo replacing the muffler

Edit: Also worth noting, as long as you size the piping right, long intake tracts shouldn't be that big of a deal.

I'm with you, sounds like a jet and it really does make sense. I'll keep looking for that thread as I'm really interested in it. The Vette they show had two turbo's and I thought I recall a two unit option on the Z as well.

I see a bunch of threads about the engine bay being too hot etc, I ran K24s on my porsche Turbo for a full year and drove it every day. Figure the venting on a 996 Turbo with the motor in the rear can't be any better then a Z car in the front, I'm not as worried about heat as long as the motor can hold up to the extra strain. On the other hand if STS can do for $5-6 grand what others want 9 grand for plus exhaust then STS may be the way to go...

damn that would sound so sick on a 370z. When it comes time to TT my car i might look into this some more.

Zguy · 11-03-2009, 05:08 PM

Been there and done that in a 350z.... It wasnt an STS kit but we built our own kit for my friends 05 Z. Its still running strong as hell... The only problems he ran into was boost leaks. Once we were able to find them all and make sure everything was tight he never had any problems. He was putting down something in the neighborhood of 390whp and has been for about a year and a half.

People talk about the lag because its so far away from the engine bay but I didnt really notice much more lag than would be on any other single turbo setup. I think he hits full boost right around 32-3500... The car feels sick as hell.... I put down 426 on my Vortech and he beat me in the 8th mile, I was running between 8.3 and 8.5 consistantly... he was in the high 7's..... made me sad so I sold it all lol hopefully soon ill be grabbing up a 370 Roadster

motoextreme · 11-03-2009, 08:06 PM

Can't beat the prices, that's for sure. Other systems are coming back at $11K or so. I'll keep checking the board but sounding better and better the more I look. Thanks!

Mike · 11-04-2009, 11:07 PM

From what I have read, the tradeoff with lag from the length of piping is cancelled out by the fact that the air temps are within 5% of ambient temp by the time it gets back to the intake manifold.

Pointman · 11-04-2009, 11:20 PM

They require lot's of plumbing, front to rear, and back.

Brazilbro · 11-04-2009, 11:40 PM

I'm also thinking about doing something like this, for under 4k you could be boosted or Less with used parts.. Keeps heat and weight out of the engine bay

motoextreme · 11-05-2009, 12:19 AM

I watched some of the Youtube video's, they eliminate the mufflers so some of the weight is balanced out there but more important, things seem crazy loud! I like hearing the turbo's but I really wish I could see/hear them in person.

GingaBreadMan · 11-05-2009, 11:58 AM

I have heard about this system for a few years now and because of this post have started researching it. At that price you can't beat it. I think it might be the best kept secret.

A friend of mine has an sts system in his Mustang GT. It's not loud at all...Actually it's very quiet. But when you hit boost and that wastegate opens up; all hell breaks loose.

Oh I forgot to mention how quick it spools up too. It's really, REALLY quick.

KingDavid · 11-05-2009, 12:12 PM

IIRC, there's a universal system as well.

KingDavid · 11-05-2009, 12:17 PM

Oh there is.

Squires Turbo Systems - Universal

$1695 for a single kit and $2745 for a twin kit. Holy hell that's cheap, lol.

I would love to see someone fab one of these kits up on a 370. There are several out there on 350s with varying degrees of success.
