STS - Turbo Kit for Pre-05

FalconGuy016 · May 16, 2006

I've seen a few STS threads crop up now and then and they always seem riddled with a bunch of doubt that the system could even work well, probably due to how unconventional it is. Personally, I have loved the idea since I found out it was actually in production (I actually thought of it myself but of course somebody has done it ). It's a relatively popular turbo system that actually mounts the turbos directly into the exhaust system - under the car. No custom headers, no relocations, no tight engine bay issues, all with an even cooler air charge than usual.

Common misconception: Turbo lag. Turbo lag is the result of a poorly designed system or a large turbo, generally, but the extra piping resulting from the unusual placement in these rear turbo setups does not create some massive wall of turbo lag. The difference is minimal. It does not take a lot of time for the "extra" air to pressurize - considering how fast the turbine actually spins. You can hear this and see this in their numerous videos online.

Anyways, being a turbo fan in the car world, I was hoping STS might consider the pre-05 crowd. It's a large base of enthusiasts, no doubt, and it would fill the hole we have for turbos. Really, our only options for turbos involve very extensive installs and typically involve new internals (I speak mainly for HP Twin Turbo at this point). But those obviously aren't for everybody.

I sent STS an email about it

Dear STS Turbo,

I was wondering if your company has considered previous generation Mustangs for an STS Turbo kit. I ask this because it seems like such a gigantic market with hardly any turbo applications due to the mounting issues involved. But since STS is rear mounted, this would be a real hit, especially with the ease of installation and no need of custom headers. For comparison, the most popular turbo kit for the Mustang is the HP Twin Turbo which starts at $6400 and up, but it is also a very involved and difficult installation. The next down is a kit by ProTurboKits at $5000, but that does not include a very expensive suspension change that is needed. A rear turbo setup, if possible, seems natural for this car. I was wondering if any thought has been made about a kit for these cars.

To which I got this response:

I agree it would be a real hit. Hopefully we have something out by the end of the year. Keep an eye on our site. Thanks

Thanks, Dave

This was very encouraging to me. I love the idea, and wanted to see what opinions you guys had about it. And if it's well recieved, the BEST way to have a company follow through on something is to show interest, by way of contact. Easiest way -> Email: sales@ststurbo.com A quick message does wonders, and it could really make the difference.

What do you guys think?

If I didn't already have a power adder...I would consider it! Especially if they had some sort of mid-turbo setup, perhaps puting the turbo(s) down by the trans, then you could run whatever catback you wanted heh.

I think it would be a sweet..There guy here that has a t-bird and has a set up like the STS it sounds so sweet when he gets on it..

Actually I would figure it would be incorporated into the mid pipe if fitment is allowed, just cause of the natural crossover point.

Edit: I remember somebody on the 94-95 forums making a home made rear turbo (may have been twin turbo even) from parts out of a Summit catalog, successfully, in only a few weekends too.

Also check the July issue of 5.0 Mustang Magazine.... It's on sale now... Pg 94..
For the street application the tough part is the lack of room in the back of our cars between the body and the gas tank.... I can tell you they are working on a solution and you're right, e-mails showing interest gives them motivation...

If STS came out with a direct bolt up kit (like their others) for a decent price I might start donating sperm to buy one, or at least sell my other ride...

Turbo all the way...

There is a company making a rear turbo kit already...
http://www.jmsproductsinc.com/
look for the Ironman sleeper turbo kit. website has a video and pics also.

Thanks for the info! Never seen that before, interesting stuff. I'd still like to STS come out with one though, nothing better than competition. I wish their video worked.

I saw that JMS kit a few months back in a MM&FF. The problems I see offhand are, it requires a rear seat delete, which hardly any daily driver people want, it doesn't use a filter over the inlet housing since it sits behind the pillar (ever thrown a stick in to a fan?), and actually requires you to drill and cut the side of the vehicle (read: don't ever plan on selling the car after that install.)

we used STS's universal kit and built it to fit our needs...

hotmustang331 · Jun 27, 2006

If all your wanting is 400ish RWHP and run a low PSI....than sure this will work. they run a small turbo with these setups and only 5PSI so spoolup doesnt take forever. But if you want to really push the power up to 500+ and turn up the boost, a few things will happen.

A. the supplied turbo will run out of steem up top and and probably wont even support 500HP.

B. Your going to need to get a bigger turbo, and lag time will get alot worse.

C. You will also need to turn up the boost...that will further increase lag time.

See turbos like heat....and the more heat they have, the faster they spool. They seem to be a great idea for a stock mustang to me.

(is it just me, or do the cars on the "freeway" seem kinda slow when they get on it???)

hotmustang331... Im one of those people who wouldnt mind running a smaller amount of boost, and hit smaller HP numbers. For me I know 5-6 psi would keep me happy for a long time, and be plenty powerful for me, while not being a huge stress on the engine.

The idea of a rear mounted turbo is awesome to me. Dont have to tear up the engine bay and whatnot, and the midpipe area of our cars seems like a great area to start one out.

hotmustang331 · Jun 28, 2006

Yea a regular turbo system is EXPENCIVE, and a SERIOUS pain if you want to do it yourself lol.
The STS setup is more affordable...just pointing that stuff out so people would know that these arent a great idea for BIG HP #s.

@5-6PSI an intercooler isnt needed at all...nor is meth.

400RWHP is alot, and this turbo setup would be good for up to that. Plenty to teach a mild bolton 03-04 cobra a lesson

I spoke with someone at STS yesterday and they said they are looking into developing a complete kit for the pre 05 Stangs.

BurningRubber · Jun 28, 2006

They can use my car as a donor...

I saw that and originally was wondering what methamphetamine had to do with making your car faster...

On a supercharged setup, you're correct. However, since turbos run off exhaust gas, they get a lot farking hotter, and the air has to be cooled down, unlike a supercharger where it's just an optional benefit to have an intercooler.

Ernad · Jun 28, 2006

if you want only 400rwhp, just get an S/C. I'm thinking that would be much easier, safer, and proven.

No, my statement was directed to the STS turbo setup. They dont experiance the heat that normal turbo setups see....thats why I said that .

But reguardless compressed air makes heat...even turbos right on the exhaust wont put out heat thats ALOT hotter then what an S/C puts out. Especially like mine, where all the exhaust pipes, and the hot side will be heat wrapped.
