I was looking at some pictures of the STS kit and then walked out to the garage and looked under the hood of my car. In the picures, it appears the after turbo pipe runs up along side the driver's header collector and primaries before bending around to the throttle bottle.
Is there room for this when you have headers? The pictures were of a stock manifold car with stock y-pipe, but with my AS&M's I have a hard enough time getting my girly arm past the headers let alone a 2.5-3" intake pipe.
I suppose if I was buying the kit I could reinstall the stock manifolds but that would defeat the purpose (easier installation) of buying the kit in my opinion.

 

On an LT1 car, any header besides shorties will require the LS1 STS kit. The LS1 kit runs along the drivers side inplace of a SFC and runs under the Kmember. I have been running the stock manifolds for 3 years now. Just got a deal on SLP shorty headers so I might be giving them a try soon.

Well then, this leads me to another question. If they run in place of a SFC, dow that mean my double diamond sfc will be in the way of the LS1 kit?

 

Yeah if you have headers on your lt1 kit then you will need the ls1 kit like I had to buy. It will fit the lt1 perfectly it's just routed differently up front and runs along the drivers side subframe connector. Which became another problem for me since I already have subframes on the car welded on. I needed to have a custom pipe made to clear that drivers side subframe. But I guess now your supposed to tell STS about your subframes and the will give you the pipes to clear it. STS states that there pipes act like a subframe. But I would not trust a hollow piece of pipe over a solid steel subframe. - Mike

 

thanks for the replies.
Detroit,
on the ls1 kit, rather than running the pipe up by the headers, does it route further frontwards and then come up between the fans and engine?

 

Yeah the lt1 kits - the pipes route from the throttle body towards - Along side the drivers side exhuast manifold. The ls1 kits - route a little differently up front they route somewhat exactly like how our air filter assembly is routed. www.jlturbo.com or www.ststurbo.com -- Check the lt1 kits and ls1 kits out - they show pictures. So you will get a better understanding of how they route. These kits are amazing thow. I can drive my car all day in the summer and it will not get past 190. I drive it normally with out running boost and when I want to run boost I just basically push the pedal harder. Then you hold on.

 

I was going to just pm or email you with further questions but if you don't mind answering them, I believe it will benefit others too who are curious about this STS kit if we talk in this thread.
Basically, I was just wondering the details of your setup with this turbo, power numbers if you have them, track times if you have them, and why not gas mileage info if you have calculated? I have really stepped up my research on the turbo set ups in the past couple weeks but would like some first hand info from a man who has actually done it

 

I had my car dyno tuned at 400/408rwtq on meth at 7psi . That was on a stock lt1 engine with hot cam. My numbers would have been higher except of the 4:10 gears that does not put a load on the turbo and the unfriendly lt4hot cam. I currently upgraded to a moser 9" with 350 gears and it's a day/night difference. Pulls even stronger. I also have the upgraded t-67 turbocharger. Gas mileage is very good -unless you get into boost. Depends on how you drive the car. STS claims it will increase your gas mileage. I defently love the system. It's different from others. Dont have to worry about the car overheating. I dont drive my car in the rain thow. It's only a summer time car. Only drivin on nice summer days. So I really cannot tell you how it drives in the rain. I defently would recommend STS. Just make sure you upgrade the fuel system, fuel injectors and have the car tuned. You will be okay. But other then that STS is a awesome kit.
