what i'm taking about is an after-cat turbo, which STS claims they are the only one to do so far. anyone else heard of or used one?

I made a remote mount turbo system for my daily driven Z24. I have over 20,000 miles on the system and it has gone a best of 12.5 at 115mph. There is a video of it on streetfire walking over a nitrous'd 5.0 Mustang.

so they do last for quite some time then? and you got a cavalier to do 12s?? what could i expect with my LB9(215hp 5.0 with TPI is LB9 right?) until i can get a decent 350, 383, or 400 under the hood?

My z24 also has a 3400 V6 swapped in from an '02 Venture van and the car only weighs 3000lbs with me in it. I drive it every day in rain, snow or sunshine. Its a very fun daily driver. Check out my website, www.khturbo.net.

I don't know what you can get with the 5.0 liter TPI. There are a lot of variables, but I think a mid-high 12 will be very possible if you have everything set up right (depending on how hard you want to push it, you could probably go even faster with the stock LB9). A remote mount turbo system is easier to build, but you still need to have a good understanding of how a turbo system works to make a successful system. Also note the complexity of the oiling system and make sure you understand how that works on RMT applications (the scavenge system isn't really that expensive or complicated, but must be thought out a little before you dive in).

You know I was looking at there site and I see they really jacked up there prices ouch!! Probably better off making a kit yourself like 89JYturbo did if you want something like this.

STS is very pricey. Their kits are selling very well from what I hear. They can't keep there shelves stocked, so I guess they figured why not hike the prices.

Surprised no other company has jumped on this.

STS probably got the idea patented or somthing, so any one else trying to sell it would have to pay royalties

I am in process of building my motor right now, when I am done I am expecting to be around 450-500hp, then I was going to go with STS myself or even build my own. I emailed STS and they do not have a kit for thirdgens, you have to buy the LT1 version and some of the piping changes around the rearend area....according to what they told me in the email. They also said they know of one other person who bought their kit and used it on a thirdgen, they were going to get info from this person and pics for me, but I have not seen them yet. But I am thinking this is the way to go on our cars.

yea, the engine bay it so cramped, and doing it this way you should be able to keep things, like AC and crusie control (not that mine works that well any way..)

acutally quite the contrary... they are doing very poorly.. they dont keep things in stock because they make everything to order, in order to cut down on costs of keeping stock... and the cost of materials.

Their oil return pumps are acutally re-stickered BOAT BILDGE PUMPS.. not even rated to carry oil.. just sea water.. their pipes are crush bends.. not mandrels.. their turbo's are bushing and not ball bearing... they use the cheapest things on the market and charge the highest prices for them..

most turbos are not BB

I agree with you on the fact that they use some cheapo parts and they charge too much. However, I'm not sure where you got your info on the poor sales. My turbo supplier (Blouch Turbo in Lebanon, PA) personally knows the Garrett performance distributor that sell to STS, and this distributor claims STS buys so many turbos that they are having trouble keeping up. I'm not trying to support STS or anything, but I'm good friends with Bob Blouch and he talks to me a lot about remote mount turbos because I run one on my Z24. He has my remote mount turboed Z24 featured on his website, www.blouchturbo.com.

I really doubt they are doing poorly.
I used to be a dealer and installer for them and they kept me busy constantly. I had so much work I couldn't keep up at my day job.

they actually have a new ceo who happens to be "J" in JE pistons.

they don't really do much of the f body kits anymore, all their business comes from corvettes and gm trucks.

While I agree with you and 89JY… that they use cheap parts, just about everything else that you said is either a bit “so what” or the same as with anyone else. I’d bet that less than 2% of the turbos out there in the world are BB turbos, and those things you’re calling bushings are technically fully floating sleeve bearings (check out some of the cool patents for those in turbo assemblies… really more to them then you expect), so I have no idea why you’d bitch about that, and things like “crush bent” pipes… I never understood why people bitch about things like that if they are not only sufficient but you’d be hard pressed to show a performance difference between them and mandrel’s in the application that you’re complaining about.

As far as I can tell, STS is doing well enough that none of their distributors can keep up with them and are making big showings at all the trade shows…
