DO we lose our mufflers with sts kit? How can we stay street legal with sts kit or can we not? I would prefer to try and stay street legal if possible. I have a nice corsa exhaust and would like to keep that and add the sts kit. Is that possible?

 

Do a search and just read up on the kit.
BTW...you will lose it. I suppose if you really wanted to, you could fab a bullet style muffler before the turbo, but I dont really see a point in doing so.

 

also if you do put a muffler before the turbo what do you think would happen if the muffler comes apart internally the turbo will quiet the car down alot the only thing that will make it loud is the wastegate.

I was told it just sounds like a performance muffler...

 

Mine sounds really good with a nice deep sound. I currently have my CATs on still so my car will pass smog. I am not sure if they can say anything about having a turbo instead of a muffler but having all of your smog stuff should make you legal??

Sell the Corsa and put the $$ towards the kit The STS with front mount intercooler will give you around 500rwhp on pump gas on your stock motor.

And Mike,I'm also a STS dealer

 

Don next year sometime You WILL be hooking me up right? I can plan on going that route. I would RATHER do that than Nitrous. Heads are still on order from felber racing. I just gotta pick a cam. I WILL go the sts route, but I'm worried how fitment will be (I'm a poor *** and have to do labor myself.) Will someone quickly look at my mods and see if ANYTHING will interfere? HEre they are:

Also do you guys have sound clips of sts turbo kit? I live in FL and there's no emissions here, but if there ever are, I would like to be able to pass them. Thanks.

PS: I am sure everyone already knows this, but you all are GREAT for the wealth of information you provide. I admit I'm a bit of an idiot when it comes to racing/building cars, but I've been learning a LOT from all of you over the years. Thank you.

Don, if you think the sts turbo is good, that's good enough for me. I KNOW you know your **** and trust you 100%. I'll never forget when my ASR light wouldn't go out and you knew it was the pulled wire from dynoeing. You tha man!!!

 

Michael,

Read your tuning FAQ for beginners at Hptuners - Very Good Stuff. I'm learning to love my HPtuners, too. Attached are my thoughts....

You'll have to take the Corsa exhaust off at the muffler. You may not need to cut it, if it's attached at the muffler with a clamp rather than joined with a weld. If you want to keep the entire cat-back system to sell, you could get stock exhaust from the junkyard and E-bay the Corsa.

No muffler does not make the car illegal. All of the emissions systems remain intact. My car, with an LS6 cam is not very loud at idle or driving around, but the wastegate is really loud at WOT. I've even thought about putting a bell on mine so it shreiks like a banshee and scares ricers even more....

All of your gear looked ok to me, but you'll probably have to lose the driver's side subframe connector - this is where your charge pipe goes. The charge pipe and bracket are very, very stiff. Some people say it's BS saying it fills the same function, but mine felt as rigid as a bolt-on connector, at least.

I went with an LS6 cam because of idle quality and the excellent lobe separation for a turbo application. Not to mention you can find the things for less then $150, with valve springs. If I would have gone with a larger duration setup, I've heard good things about the reverse-split turbo cam Synergy developed. (think he's a sponsor)

Only other thing I'd add is that from your FAQ, it looks like you're a Speed Density guy. I run a MAF sensor and will at least until HPTuners ver 1.6 and support for 3-bar MAP sensors and boost enrichment. I'll also be running a wideband O2. Bad, bad things can happen really fast under boost without being certain on A/F.

 

If you mean legal as in noise polution, I think you'll be fine, these kits are quiteter than a loud flowmaster setup.
If you mean legal as in smog, it's coming soon. CARB approved!

sfc's and cut out have to go. the cut out will not seal well enough for boost.
My car is stock with cats and everything and it is not loud at all.

 

Aren't SFC'S good for our cars? Isn't there a better route to go than losing your SFC? Can you custom fab something or even weld that big pipe to current SLP SFC?

 

You would have to cut out the SLP subframe.The STS one that takes it's place is very strong.

 

so you weld in a sts pipe as a subframe? Looks to me almost like a botch job. Kinda scary. Wouldn't look uniform to have a SLP sub frame on pass side, and piece of pipe welded on drivers side.

 

That piece of "pipe" has flanges just like a sfc; thick flanges that squeeze the frame and a flange that the lower control arm bolt goes through. If you had sfc's that were smaller, it would match better since the slp's are large.

 

I think with the mods you already have, a supercharger might be a better buy. I picked an STS setup myself, but with the longtubes, catback, and cutout, a supercharger should work pretty well.

 

But Supercharger is a lot more money. Like 2k more. Or am I misinformed?

 

you have slp, you already have a botched job Look I have 4130 wolfe tubular subframes and there the best, I lost one for the STS, theres zero difference.

 

slowhawks selling my d1 with 8 rib upgrade and about 1k in extras, its got 3k miles on it apporximately. I will let it go with the SC cam I ran with it for 4400. I made 630 rwhp and 546tq at 10 psi. I used patriot 6.0l heads.

 

would you take payments? If so I can start paying $100 every 2 weeks as of right now, and as funds avail. large chunks. I would take that in a heartbeat but do not have the cash this second. Please PM me if we can work something out.

 

PM'd you
