As would I. Pretty cool stuff.

I wonder what it would cost to get a shop (aam/jbm/forged/someone notable) to fab up the piping and install this on the z

I think an exhaust shop can do that.

Just finish speaking to the guys at STS hoping to talk them into making a kit for us. We spoke for about 30 minutes and after the R&D guys come back from SEMA they will discuss it. I have a feeling this kit will be available for us.

I would definitely consider an STS system. I hope they go through with it.

Is there room clearnce for it on our cars? We know the aftermarket mufflers stick out so will the trubos stick out too. Id hate to scrap one of them.

The mufflers are replaced by the turbos so that shouldn't be a concern. The other advantage of this system is there is no need for a aftermarket exhaust. The stock exhaust is used to aid in back pressure for the TT's. Less restrictive aftermarket exhaust would not be beneficial for this setup.

what turbo would be good for a single setup? you think a 35R would get it done or would a 37r or 40 be better?

Considering KindDavid's response I'm 100% in! Thank you GingaB.., I sent them an email but haven't had time to call. For this price I'm willing to give it a try. I bought the car last week with every intention of adding a turbo or two. I was ready to buy a Turbo Porsche as I love the feel but didn't want to spend the $ and wanted something I could build up a little myself. With a little reseach I'm just not ready to drop $14K or so for a new set, exhaust etc. I just dropped a few grand for a stereo and brakes are next on the list so 11-14K for some more HP is more then I can justify.

Anyway, I'm ready to give it a shot and hope they come through!!! Thanks again for looking into this

well if this happends ill defently do it when i complete my tour to afghanistan in 3-11. What im worried about is the safety inspections in my home town where i plan on moving back to in a few years, they are really strick. So im worried my car wont pass inspection if it has this kit on it.

There's your answer about lag.

Dont waste your time on an STS turbo system.


I would really steer away from them, don't own one but had to tune it and it just can't be properly tuned. I had to get it to the best aproximate safe tune.

- The turbos are tiny, tiny (twins) I would not expect upgradibility with such small things.
- The lag is just unbeliavable, this is my first time that I've ever had to do such long runs in the dyno so they could spool (dynapack dyno that you could apply 100% load as different than others), I even had to do the runs three times so the system would got to a level of temperature so the turbos would actually work.
- This is the lone FI car that when at WOT you would still measure vacuum for some time down low.
- To get it to a decent power level we had to replace the WG spring so it would make 8psi and get us into the 4xxTQ/HP range.
- They use quality stuff in their WG and BOV (Tial rebranded as STS) (or at least that is what it looked like)
- So they could get a CARB number they went thru the most incredibly complicated PCV control system that is a mess of wire and hoses in the engine bay. (A hobbs switch controlled purge valve to the intake)
- Everything sits pretty low, specially the piping that goes below the transaxle.

I would really look elsewhere for a turbo kit.

I don't believe passing inspection will be a issue. I wanna give thx to the OP. It resparked my interest in this system

I'll double check with my friend, but I don't recall him or his tuner having any issues at all. He has the same mustang as yours and it's been running perfect for over a year and a half. 490/470 and he hasn't had a single problem ever since. It spools up quick. Barely any lag. Installing and tuning wasn't a hassle either. He got it done at Mobile Mod Performance in south fl.

We don't have any carb issues to deal with since there's no inspections like that down here. But wow, first I've heard of this being a problem.

Oh but I'm not going to sit here and act like I installed it or something or I own his car. Sorry if I put it out there like that. Just a bit baffled, that's all. Maybe he got lucky? Or maybe you just got unlucky? Lol, I dunno. How long ago was this install?

Edit: So I just finished chatting with him. It's a little laggy but barely noticeable. Nothing bad at all. No issues with car whatsoever since having installed over a year ago. The install and tune went smooth with no problems. He is on a single kit. He still is making 490whp/470wtq with stock internals. We live in south florida where if it isn't sunny, it's raining...a LOT. No water damage, no cracked turbo, turbo was not mounted low. His car is lowered actually and everything has been ok thus far.
