Hello, I have a 1998 C5 Corvette. I'm looking to get a lot more out of my car, and I'm stuck between a twin turbo kit from STS or a supercharger. I've already talked to the guys from STS. They were really easy to talk to. I really have not looked into a supercharger yet. But right now I'm kinda leaning toward the STS kit. I like the fact that it's a low boost kit... the only downfall is the turbo lag, which this kit seems to have a lot of.

But I guess what I'm looking for from anyone reading this is.. what's your opinion?

STS Turbo- Good or bad?

Supercharger VS Twin Turbos?

Overall opinion

I'm interested in the reply's you receive but you might want to post your question in the FI/Nitrous section

Just from "cool" factor, I would think that the twin turbo set up would be the ticket, but I don't know and will be watching this thread for other input from those who do know!!!!! I do know that turbo set ups are way impressive visually, if that means anything!!

I think it depends on how you want it to behave. Quick launch drags? Forced induction blower! Running laps you might be better off with the turbos...both are really depends on where and when you need the power. I think the blower is much cheaper and less involved install as well. ..Better experts than me will chime in I'm sure

To much unknown here. (1st) do you do alot of your work here. (2nd)how deep is your pockets. The most power for the money here is A/A or ECS. These will get you into the 750 too 900 plus rwhp. But if you like the T/turbo,s set up a diff set of problems altogether. If you go turbo,s hope you have deep pockets... Robert

I dont know much about the turbo system you are talking about, but I can say the ECS supercharger is awesome. I had one installed by Them recently, and love it. The guys at ECS are very cool, and easy to work with. Either way you go, turbo or supercharger, your going to have a lot of fun when its finished.

SC's are easier to install and a lot cheaper. The STS system is in the rear of the car which brings up a whole other set of issues.

I'd go with SC if you plan to drive the car a lot. Also watch how much boost you run or you will be looking at a new motor.

Another nice thing about the STS kit is that it's right around 9-10 grand.. including having the guys at STS install it. How much would the ECS SC run me?

A lot of you seem to be saying that if i get the turbos.. i'd need deep pockets... which kinda implies that i'll be running into a lot of problems. I'm kinda looking for minimal problems as well haha (as is everyone).

Do some research, the STS system has an oil pump in the rear to lube the turbos, if it fails or you have leaks, etc ...

The tubing runs down your inner rockers for the charge pipes and you would not be able to have catalytic converters on you car, becuase if they ever break up they'll take out your turbos.

The STS kit will be loud as the only muffler will be the turbos.

The SC's don't have any of the issues. Easy install and linear power control.

I believe supercharges are more reliable. Cheaper and easier to install too. And some are completely emissions compliant.
OP mentioned liking low boost. Both the turbo and supercharger are going to push low boost on a stock engine. It revolves around what the engine can handle, not what the kits are capable of.

vendors in here selling and install and tune for 6199.00A ton of guys in here able to put what ever on your car. Then a ton less that are a true tuner of a car. If on east side of the world go ECS on west go A/A man will not go wrong with one are the other.. Robert

I'm located near Green Bay, WI. I've heard a lot about Speed Inc... they're not all that far away from here. Would they be a good selection to have install it?

Get out your DVR and look for the last two episodes of "Two Guys Garage". They put in the STS turbo kit for a Wounded Warrior.

Basically, here's the pro-con brakedown:

Supercharger:
PROS
- relatively easy to install
- instant throttle response (no spool time)
- typically less expensive than turbos
- Much less plumbing involved (air and oil)
- Can be used with Common aftermarket exhaust systems and headers
- Easier to tune
- More reliable due to less to go wrong
- More consistent power curve since it's directly linked to the engine.

Cons:
- Lack of tuning options
- boost levels is fixed based on pulley size
- Allegedly less efficient than turbos.
- relatively linear power curve


Turbos:
PROS:
- gives you a lot of options for both boost and tuning
- boost can be adjusted on the fly
- Supposedly more efficient at making boost than SC units
- Has a steadily increasing power curve: the bigger the "bang" in the cylinder, the more it pushes the turbo and the faster the turbo spins resulting in that feeling of being "launched" after the turbos spool

Cons:
- LOTS of plumbing required.
- Typically a lot of modification to the exhaust system on non-DIY kits
- Significantly more expensive than most SC kits
- More difficult to control if you're not used to it
- Poor boost-throttle response without a specially designed cam

Look up are give Mike Norris a p.m. Which ever way you want to go I know he can tune it and put it on your car.

Neither,,,go with the TTi Kit...best on the market!

Turbo is arguably better in most respects, but it comes at a high cost.

S/C is much cheaper and easier, and its less complicated, both in the install and the way the car drives.

From the sounds of your posts, I think S/C is right for you (this coming from a turbo guy!)

So if I were to have a local shop do it, could I still have it done for that price? Or something close to that?
