STS Twin Turbos Or Supercharger??????
 

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 :cool: 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 :cheers:

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.:cool:

:iagree:

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 6199.00:thumbs::thumbs:A 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. :thumbs: 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.

Little closer to you is Late Model Throttle:cheers:

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. :thumbs:

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

The Big Dog

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!)

:thumbs:

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?

By the way, thank you everyone. I'm leaning more toward a SC now. Granted the TT kit would have more of a fun factor to it... my pockets aren't quite deep enough haha

Neither.
Spend the money on Kinsler fuel injection or a stroker. NA is the way to go.

ECS has an iinstaller registery, shops that are certified to install ECS kits. They've also solved the "can't go bigger unless a pulley swap is done" years ago with a restrictor plate. DIGIVET is over 1000rwhp and is a regular (took 1st place this year) at the ECS challange in Englishtown. Give them a call, 609.752.8391. or visit www.eastcoastsupercharging.com

I had the same debate with myself, did a lot of research, and went with the STS. I wouldnt hesitate to do it again. But yes, it does get expensive - no matter which way you go. My advice is to find local people with each and go for a ride and see what you like better. If youre in FL, I can hook you up.
Ive always been partial to turbos myself- especially with a small whiff of nitrous.
What are your ultimate goals for the car?

The Turbo system itself may have more parts that can fail, but a properly system should eliminate most of that...I'm thinking about going turbo too, but mostly becuase turbos are much easier on the cars drivetrain and engine than an SC in the long run, so in many ways, a properly designed and installed turbo kit is probably more reliable overall than an SC system in my opinion....but it costs a bit more to do it right

the guy who said NA is the way to go probably called it right though....for about the same money you can get as much power as your looking from a bigger engine swap.

I researched turbo systems and liked TTi and the Hinson single turbo system, the latter becuase it seems to have the best overall cooling system, which is very important for reliability on any Forced Induction system...Hinson seems to have the best designed cooling of any FI system that I have researched....its water to air and has its own reservoir tank, run alot of water through the sytem amd not only cools the FI system, but keeps the whole engine cooler, which means better overall longevity for the car.

If anyone has the Hinson system installed I'd personally like to hear some feedback.

A&A and ECS are hands down the best SC systems out there IMHO

Do a search in the forced induction section. I've heard a lot of complaints about the sts system but have no personal experience with it. I went with the ecs kit and I have no complaints so far,the car is a beast! Also to the people suggesting N/A there's nothing wrong with it but I don't see to many N/A guys running 700-800rwhp.

I went twin turbos with forum vendor UPP. 8 psi I'm making 635hp and 650tq and I'm super happy! Regardless what you go with plan for a new clutch. Because it will go out at the higher than stock hp levels

Get a A&A or ECS kit and call it a day all will be good:rock:

:iagree::thumbs::thumbs: You will not look back man.. Unless you are wanting to get into the low to mid 8,s race car then BIG TURBO,S..

How is the STS running today? You still have the car?

Yes I do still have it. Have not been able to drive it recently due to 2 hip sugerys this year and some severe complications.

I have been looking at the UPP turbo system, running 635hp did you go through the bottom end of the block or are you running on a all stock block? I heard time and time again that you dont want to push the stock internals past 600hp.

Not to hijack the OP's thread, but I'd like to hear some thoughts on a Magnuson SC. I know it doesn't fit under a stock hood, but how does it stack up against the other SC that have been mentioned.

stock internals:rock:

EDIT: I didn't see any mention of trans if auto you better start there if boosting FLT or rosler perhaps add boost and you'll be buying a trans in short order

I put the radix on my 2001 gmc short bed truck @ 10 psi 3.2" pulley it didn't take long for the 4L60E to live up to it's reputation for being vunerable. 3 weeks later it grenaded well it didn't break anything, but it smoked the band, clutches looked ok

I bought it from magnuson direct easy to deal with if you're looking for 80-100 hp it's a decent route

wanna ball with the big boys turbo is the way to go but you'll break stuff @600 horsepower

If you are not an experienced driver, turbos probably won’t have a more “fun factor”. Install the A&A or ECS kit, go on and get a cam and nice exhaust, and run E85. Once you smash 650+whp for the first, and you don’t die, you will understand the “fun factor” much much better. Lmao!!!!

Bro...this thread is OLD. :gramps:
Pretty sure they made their decision a long time ago.

LOL!!! Didn’t even realize this.
