Default STS Turbo Kit

For those of you who do not no the STS kit, it is a rear mouted turbo.
There are a lot of people who do not agree with this kit, but i beg to differ.
the Kit is installed in 4 hours, retured back to stock in 1 hour ,for those of you who are attached to your headers you get to keep them (no turbo manifolds)
maybe not an ideal kit for the big guys who want 700rwhp and to run 9's or 10's but its an ideal kit for 450 to 500 rwhp fun streetable car. Someone(Rick at STS)has finally made an affordable turbo kit for the ls1 with easy installation runing a safe 5psi out of the box on the stock motor.
This is a great kit for those want to enjoy the thrill of turbo in a cheap manor.
Thank you Rick for building an affordable kit.

the kit is real, the gains they have seem to be real.

only time will tell how it performs in the real world.

they have g-tec times at high altitude...

right. thats whats got me kinda of skeptical is that g-tech crap. ls1 motorsports is advertising right near 500 ponies at 7 psi. psi is psi isn't it? so with this kit at 7 psi there might be a little more lag but should be near the same right? thanks

how do you fiqure 6000 cheaper? more like 1500-2000 cheaper. also your getting alot of custom fabbing and intercooler with qmp kit. im not trying to bash but i can see the difference in cost. also with the ls1 kit not out yet, how much different is the lt1 kit? all i can imagine is the tubing to the intake.

I saw the LT1 car dyno. It made very good power, especially considering it still has the stock fuel system. The G-tech times are prolly off quite abit, but I have no doubt the car has a mid-high 11 in it.

I am going to race the turbo camaro in about 2 weeks, and my set-up should be capable of mid 11's at 5000 ft, so it should be a good comparison.

The STS Kit uses methinol injection for there intercooler system they tryed to put a intercooler on but the lost 3psi when the did, and sence rob is installing all of his kits now,
7000+1500install= 8500 then say 500 for tuning
9000 STS evrything with the methinal system is going to be around 3500 because they had to add a sfc with the kit so about 5500 diff.
Not bashing Rob's kit because thats been my dream kit sence i saw it but i have to face reality 9000 is way out of my buget. STS Kit if I trap 120 with it just bolt on ill be more than happy

do you have to use methinol? is that something you have to constantly refill? im sorry im a noob at this. cant the psi drop through a cooler be compisated by uping the boost? his site says the turbo in the kit can support up to 15 psi so if you run a 7-9 psi boost cant you just slap an intercooler in and turn up the boost allittle to compensate? i need to find some reading like turbo for dummies or something! thanks

no but it is advised to use methanol it only kicks in at full boost 6.5 gallons of 50/50 mix water methanol it last 24 min of full boost that a long time

sounds like a poor intercooler design. turning up the boost to compensate isnt a good solution because youre trying to cover up the problem and not fix it, plus youll be introducing more heat into the system and heat in the intake is bad.

^poor intercooler design?

it has no intercooler nor does it need it.

it does 5 psi with stock EVERYTHING, they offer water and/or methanol injection.

if i'm not incorrect they were doing 14psi with this same methanol kit.

u can put an intercooler if u please, that + the methanol injection is a great combination

Also as far as lag, it's no more than aregular properly sized turbo..

Garret designed this to work from the "rear" ONLY..it would probably lag if mounted on the front.

that is the ONLY kit on the market that can be bolted on my regular joes, in minimal time.

and as far as introducing heat..well u forget u don't have a turbo in your engine bay so it's much less heat to begin with.

the righ water/alky injection will negate the need for a 35 pound intercooler that some of these kits put on our ALREADY nose heavy cars.

u can have this in your car and ready to go under 4000 bucks. nuff said

they can also fab up a CUSTOM TURBO for u, in case u do want some more serious power.

If it lost 3 psi across an intercooler @ 5psi of boost then I think that qualifies as a poor intercooler selection. That doesn't mean that the kit is bad, "needs" an intercooler, etc - it just means that that particular test wasn't really representative of what you would see in a real world application, and not a fair comparison.

Re lag: The lag would have to be greater - will it be "bad" - no, not with proper sizing, etc. - but simply because the gas transport distance to the turbo is longer it will have to be a little "laggier". Of course the turbo selection is going to have a bigger effect on this than most anything else.

It looks like an interesting setup, I still have a few question on it though

What scavenger pump (oil) is being used, and what type of MTBF does it typically have?
From what I understand additional fueling is provided by the methanol injection system? How is this calibrated - does it add extra fuel based on pressure, etc?

If I had computer tuning done would I need the Methanol Injection??

Also does anyone know what is so different about the Turbo's they use than a convential say T3/T4 .60A/R ??

I am very interested in this kit , I want to make sure they are using Quality parts .

Been ripped off in the past by Companies and there false claims ... Want to make sure it is worth it .... Any one on here have there kit ??

Thanks

I have to think you are not including tuning in this. I don't care where your turbo is, you cant get 30 degrees of timing with 5 psi of boost.

For the money it is a pretty good deal, but my buddy just picked up a LS6 Head/Cam package from TSP (with no core) for something like $2300. Even installed (add another $1000), these two kits would be comparable. I think the benchmark will be if it can beat a head cam car or not. That has yet to be proven on an LS1.
