What do you guys think of the rear mounted turbos that sts has I just need some input becase Im seriously considering this option. http://www.ststurbo.com/ls1_camaro_dyno

They seem to be good..........there was an article in either Camaro Performers or Chevy High Tech Performance bout it. Forgot what exactly was said about it but i'll find it and tell u what it says........maybe they have the story at the STS website. Gotta go for now though but i'll get back to this.

seems to be a good kit, not the best but pretty cheap. I hope they drop the price a little bit to compete with the other kits coming out. The other ones can be had for a grand more or less. There is a performance shop out by me that can get me 410-420 rwhp passing California emissions with heads/cam combo. They told me the price for parts and labor would be around 3 grand depending on how much I get done at once. This is a very good number for the power produced and much more reliable since forced induction is more prone to needing a rebuild sooner than later. Of course the STS will soon be able to pass emissions, which is something I don't think the other turbo companies can do. Also for the 4 grand price its still a good price for FI as a Powerdyne is 4 grand and many superchargers are over 5. The one good thing about this kit is you can install it yourself, although it will need a tune. The bad thing is it can be stolen easy, and if the cats break than it can ruin the turbo. Some guys say this won't hapen, but I had a car NA that blew the cat through the muffler than blew a hole in the muffler cause that got clogged. Maybe htere is a way to protect the turbo from any debris, I don't know so this is a concern of mine. I am looking at this kit as well, but am waiting to see how those eaton superchargers come out and the price of course. They have instant boost and no oil lines and no oil changes for 100,000 miles(in the units themselves) Anyway How much power are you wanting? 400rwhp is a good amount for most cars which can be had NA if you want 500rwhp than i'd go FI

Im looking for something upwards of 400rwhp and since you mention it I live in california, would I have a problem with emissions. Im also concerned about reliability would I be better off with a supercharger. Also where is this shop in CA youre talking about sounds like a good price.

thisis the place http://www.superiorautomotive.com/ located in Anihiem. I only talked with them on the phone and they wanted me to come down to talk real numbers for price and power. the 3 grand they told me sounds real cheap as well, and I'm sure a trip down there might lead to a higher price.

you shouldn't have any problems with emissions, you could take the turbo off and they couldn't say anything to you. But STS is looking to get CARB certified and in the process from what I hear, they should be able to pass since thy don't move the cats only hte muffler and thats not going to stop a CARB badge. Far as reliable, if you keep the boost down on the street you'll be OK. the STS owner told me to run water injection on the 5 psi when daily driving and methonol for higher boost, and with a boost switch you can turn the boost off or set it to any psi you want. FI cars are more prone to detonate because the pistons are more britle and will break, crack, or blow a hole right through the piston. This can happen to NA as well, Its happened to me! Mine broke into about 4 pieces. Its much safer to run NA unless your bottom end can support it. With that said water injection and low boost should last some time as long as you have a good tune. I personally want the cheapest route possible, I know there are some vendors for the STS that are below 4k, of course upgrades such as the injection might bring that up past the 4k mark.
For emissions concerns I'd rather go FI since its much easier to get high horse numbers and keep drivability and gas mileage and not have to cut cats off and all that other stuff NA guys do. I'm not a huge fan of the centrifugal superchargers since you don't get max boost until redline, and each gear it must build, with turbos you hit full boost much earlier on, some say the STS is slow at doing this compared to other turbos, but its still better than the superchargers. From what I keep reading full boost hits about 3k, as compared to the chargers 6k or so. the superchargers you must worry about belt slipage and squeezing it into the engine bay, I haven't installed either but the STS looks much easier to do. Also since superchargers run off of the belt they suck more power so a turbo will make more power per boost in general

there's a shop in jersey that can hook you up...3 grand for a turbo. but, i guarantee you'll be coming back for a rebuild. once you put the boost down, you'll want to put down more. any way, they will custom build your headers, either twin or single...whatever you want. they are called Suttons speed. they had the purple ws6 that smoked the gsxr on the net somewhere around here...i have it at the home pc, but not at work. any way, that setup costed, but they did an engine rebuild, headwork, tune, turbo install, suspension, rear end, driveshaft, tranny, intercooler, rollcage, seats....and tons of other crap all at the same time. i've seen that car on the turnpike, i wouldnt dare mess with it.

any way, the 3g mark for a turbo can easily be had, you find the parts cheap, bring them to a reputable shop, have them make your headers/flanges and put it all together. i was quoted at right around 1150 for lt1 turbo headers, that didnt include the other parts required, but it was for the hardest to come by

Also remember that just because a shop can fab a turbo setup it doesn't mean that it will perform well. As far as the STS, I still haven't seen any track numbers worth a **** out of it. As far as detonation you really shouldn't have to worry about that if your tuner is good. If he sucks you'll know real soon. Worry more about over boost, get a good boost controller, wastegate, and gauge. Iv'e been running 11psi on a stock lower end on 93 octane for 2 years now.

Car Craft or GMHTP did an article on the STS. They got over 400 rwhp w/5lbs boost on a totally stock f-body. When they stepped up to the optional higher boost set up w/ alcohol injextion they got IIRC 50 more rwhp.

There is a place in the DFW area that built a remote mount system that got IIRC 488 rwhp and over 500 ft/lb.http://www.ls2.com/forums/showthread...&highlight=sts

When i read the article in a magizine i was pretty impressed with it. I thought it was pretty cool. I did think of one thing that would be pretty cool with it.

if before the turbo you could add an electronic cutout you would be able to run it through that or u could have the option of running through the turbo.

By doing this you could turn your turbo on or off. you then wouldnt have to have pressurized air running to the engine all the time and wouldnt wear the engine down as fast.

And since the article said with the turbo the car was actually quieter than stock you would have the option of having a louder exhaust.

i didnt really think through this too much so i dont know how feasible the whole idea is. just something to consider if you do do it. n e comments on this would be kinda nice too.

I noticed the STS turbo setup in a magazine I think it was chevy high performance or one of those magazines. I was impressed with the numbers it put down and I liked the fact that it came in a complete kit(except the tune).
Does anyone know of a good place to get a tune near Fresno,CA or Bakersfield,CA even in LA. What exactly is water injenction im not to familiar with that.

If you're located in Frenso then I would just make the drive up to Synergy Motorsports in Fremont, Ca. 510-796-3749.

They are the Norcal Auth. STS Retailer and have done enough systems to know how to tune them properly which IMO is the biggest issue with turbos.

My truck runs great with the STS kit and my mods. My truck is heavy as hell and yet I still ran low 12s.

Also, 400rwhp N/A is TOTALLY different from 400rwhp with a turbo.

anyone know if there is a southern cali dealer?
F8L Z71 I know the torque numbers will be higher with the turbo than NA, but what are some other reasons for a turbo feeling different than NA giving both engines the same power output such as 400rwhp? I'm guessing hte turbo would be more fun on the street since its not like a high RPM heads/cam combo.

they feel different because an NA combo is very linear, you dont feel the acceleration as much. A turbo might feel faster because when the turbo hits there is a sudden rush of power, and you can feel a sudden change in acceleration.

I'm saying that you could possibly hit higher #s sooner with a turbo than N/A. With full boost by 3500rpm or so you could easily see higher #s with a turbo at 3k-5k than you would on a similar cube N/A car. For example an N/A car may max at 400rwhp at 6k rpm. A turbo car may max at 400rpm at 6k but from 4.5k-6.5k it could still be at 400rpm where as the N/A car might only be at 320rwhp at 4.5k and 380rwhp at 6.5k... It's an exageration but my idea is the same.
