STS Turbos for V6

[CM boyd]

I emailed STS Turbochargers concerning the application of a LS1/LT1 kit modified for our
V6 Firebirds and Camaros. The instructed me that
they were currently not interested in this product but were mainly focused on V8s. All that is needed is a turbo that will fit on a V6 like the one used for the Tacoma 6 cylinder truck and
a different hose and connector for our style of
throttlebody! They still wanted to sell me a kit
or make me a distributor for their products. I could put together (and I have) everything that they sell at 1/3 the cost of their base kit or
less. I got a turbo off a GN (.48 exhaust A/R)
hoses, clamps, connectors, blowoff valve, piping,
and electronics to support my own unit for about
$1000. I wll be integrating this into my bird this
weekend. Let's see how well she runs. I hope that she will still perform well and pass inspection also (not knocking anyone else kit).
Several people have already made remote units for
V8 F-bodies with good results also! Why not us?

Oh by the way, anybody want a parts/price list
from me just respond to this post!

Me and another person on this board were researching this extensively a while ago, but i sorta lost interest in puttin FI on my car, and he is still looking into it i think. I would LOVE to see hwo this turns out.

Me too, I already have headers, MAF Spark Translator, Spiral Max inserts, CAI, Boost a Pump,
FMU, JET ECU, Walrboro 255lph pump, Accel coils/
300 Race Wire, TB spacer, Wp pulley, ground wires, torque converter, and alot of other stuff that makes the car fast. I am trying to go 0-60
in about 5.5 seconds. This is my real goal with
6lbs of boost. I will let everyone know.

"integrating" ? Wow, that's the wildest word I've ever heard about installing a turbocharger. Enjoy the welding.

BTW, there's no good reason, other than exhaust gas volume, that an STS kit wouldn't bolt right up, other than a bit of underhood cold-side modification due to the few inch difference in TB location.

[Tyler]

it was me and ian looking into it. I have came to conclusion that it will very inefficient on our v6's due to the fact that our cars done push exhaust at the rate the v8's do. even if i went from the 3 inch pipe to 2inch pipe to the turbo it would still be ehh as far as spool time. That and i lost interest in building that type of kit.

i have since then came up with a nice custom design that i will not be discussing until all the piping is made.. which will be AFTER im done taking my welding classes. heh

STS doesnt work very well on the V8 cars IMO, for reasons I could type forever on...... The V8 cars can get away with it because they move so much air. Dont waste your time doing this to a V6 car, the performance will be horrible. STS=JUNK

[Teufel Hunden]

STS equipped V8 cars have proven over and over again to be dyno queens. Even the poster child STS car, with a built 396 LS1 only ran 12s. To put a system like that on a V6 car would be a joke. You have MORE than enough room up front to build a REAL kit, so the thought of doing a rear mount doesn't make a whole lot of sense.

I think I will work, I will be finished with my remote mount kit in two days. I have a garret t3 from an SVO mustang welded up and the exhaust side hooked up, tommarrow we will finish running the intake side then saturday we are setting up the FMU, running oil lines, and hooking up all the gauges, then we will really see how inefficent and a bad idea it is. oh and here my proof and what made my mind up about building this kind of kit http://www.thirdgen.org/techbb2/show...hreadid=238864

2.8l 89 cavalier
best na-low 16s
first time out with turbo 6 psi-14.798@94.19 mph 2.33 60 ft
best run- 10 psi 13.96@98.72 mph 2.09 60 ft

all these times are on a completly stock (exept the turbo) 2.8l cavalier with 178K miles on it

You cannot defy the laws of physics.... simple as that.


Compared to a good kit, STS will have a significantly higher boost threshold, and more lag.

There's a reason every car manufacturer puts the turbo as close to the manifold as possible.

[yellowfbod]

I'm not saying that it is as efficent as a standerd kit, only an idiot would say that, as you said the law of physics prove that. I just don't think it as much as a waste of time as you guys think and that was my proof. for half the cost you can put this together and still be fast, granted I will never see anymore than 6-10 psi but I got into this knowing that and planing on adding 100 shot after I finish my forged rebuild, but my point is that it effectivly works, be that slightly less efficent, but it works

[John_D.]

I'm interested to see how it works out. [img]smile.gif[/img]

Someone asked me about running a supercharger all the way back there? Same problems I assume. I think that STS should do more research as to correct compressor, a/r ratios, etc for thier kits. They just pluck a turbo off teh shelf and expect great nummbers.

It would be much harder to run a supercharger back there, as they are driven from the crank. You would have to rig up quite a complicated drive system to do that.

Hey, you guys are great. I really appreciate the feedback. I feel the most important thing to me is the attempt to try this set up! I took half the day off and went to Three Star Muffler where they did all the primary installation of the remote mount kit. Honestly, for those who think it is a joke I started the engine, adjusted the wastegate, and instantly got blasted by compressed air from the compressor outlet. Although the compressor is not fully plumbed into the intake (time constraint) I can hear the spool around 2500 RPM up to 5500. It really sounds impressive. I just wish I had time to complete the assembly. I know that it will work perfectly because I am using a smaller exhaust turbine (.48 AR). These are about the same for the Tacomas in the expensive STS kits! It looks impressive,but we will see
how it performs tomorrow when I finish. I think it will be fair to say that the "joke" is anybody
who pays $3K-$5K for something like this or a front mount that cannot pass an emissions test. Regardless, functionality, reliability, and performance are the deciding factors for turbocharger systems. This is clearly subjective to the owner/ tuner who has a specific goal in mind. Its not fair to pass judgement on any setup as long as it works!!
