STS Turbo?
STS Turbo? I know its been talked about alot but here we go. I have a 98 camaro ss m6. Just has lid, pulley,and cutout. It is my weekend and nice day street car. I want more power out of it with drivability of a stock car like it is now. Seems the sts rear mount is the best way to go. I mean, 450+ hp with 6 pounds of boost on a stock motor seems badass to me. How much more worse is the turbo lag. Also, can I get away with buying the stage 1 system for 3800 or will I need anythig else. What other parts will I need to upgrade. I have stock manifolds and y-pipe. Would it be worth anything getting some highflow cats? Fuel pump......Springs...? Let me know guys, This sytem just seems to be badas for the price and power it makes. I dont have 6k to soend of a differnt system or a blower but I can pretty sure afford the sts system. 
So, what are your opinions of this system for a street car. I dont care about super crazy power but 450+ would be good enough for me

sts turbo is a great kit, the power is a lot more efficient because with a supercharger you need power to make power unlike a turbo where the exhaust is always there. You will want to upgrade your fuel pump and go with bigger injectors but as for the stock manifolds, cats and y-pipe you can leave them because with a turbo you do not want any exhaust leaks what so ever. I gutted my cats and only got another 8hp out of it. As for the turbo lag im fully boosted at 10psi @ 3,000 RPMs and you'll want to keep your stock gear ratio, 3:42s? the more of a load you can out on your motor the sooner- the faster you'll boost.

A D-1SC can make 500 rear wheel with the proper fuel mixture, conservatively. As for drivability, the efficiency of a D-1SC is much greater than an STS kit. 5psi STS < 9psi D-1SC. 9 psi being conservative assuming stock bottom end. With forged internals, the ProCharger can push 12-14 psi. Its going to take the STS kit much longer to spool, not to mention the train lengths of plumbing that are needed to run the air back up to the front of the car.
Actually you are incorrect.
The STS kit DOES indeed require bigger injectors. The claim that they don't is essentially false. Almost EVERY properly tuned car I have seen running even 5psi is already maxing out injectors. I'd be as bold as to say that the STS kit can match peak #s of a D1 lb for lb and have better midrange. The D1 will require headers and exhaust mods to usually reach the 500rwhp mark just as much as the STS kit will require additional mods to the fuel system to do the same. Why are you comparinf 5psi of STS to 9psi of ATI??? The STS kit is going to be used with a meth injection kit or an intercooler for anything above 5psi anyway.
"With forged internals the Procharger can PUSH 12-14psi?" What does this mean?
The STS kit may or may not take longer to see 1psi than the Procharger depending on the head units you are comparing but the STS kit will see FULL boost sooner which is why it has a higher AVG. HP than a typical centrifugal. Again if everything is equal.
Centrifugals are great and have their place. I've owned 2 on my Mustang. But make sure you have the facts straight.

I have had my STS kit on my truck for 8 months and it has performed flawlessly. Only mods I have made to the engine are a tune and 30lb injectors. I am running 8lbs of boost with no intercooler or meth and making 400hp and 429 tq. I will be putting an intercooler on it this weekend so I can run 10lbs of boost or more. This kit is awesome. Dont listen to all the people that tell you they arent as efficient because they dont know what they are talking about. They dont know the facts and they dont have the kit. IF you want facts only talk to the people that have them because they have the facts. Before you take anybodies advice. Dig up all the info from people that have turbo kits, supercharger kits, and whatever direction you may want to go with your car. Only ask them about what they know about the specific kit they have then make your own decision based on the info you have recieved and get what is best for you. Anyone of the applications would be great. As long as its what you want. Not what someone says is what you need. I have run everyone of these applications at one time or the other and they are all good for what certain people are looking for. Get what is best for you and what will please you.
