Red03SillSS Posted February 19, 2007 Report Share Posted February 19, 2007 I cam across a HELL OF A DEAL on a g67 complete sts kit w/ 8,000 miles on it. How would this perform on my truck? Abd how much boost could I run. Also how would my tranny hold up? Current mods to it are trango shift kit, 2800 fuddle converter, and corvette servo. Thanks in Advance Daniel Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted February 19, 2007 Report Share Posted February 19, 2007 (edited) If you are getting it for half off...yes...if not no. Tranny will hold up abotu a smuch as a super charger. Off the shelf, STS's run about 6psi of boost. You will need an intercooler to run more. Anything over 10psi will require meth and the stock blocks have issues it seems over 10psi. Gains at 6psi are not that impressive. In my opinion, if you are going to end up spending $4-5k, you should just buy one of the used radix's in the for sale section or buy a new blower for about $5k and be done with it. Side note...STS kits are not cheap as they the base kit is lacking essentials like a tune, injectors (theres almost a grand right there), fuel system upgrades like pump, and you will definetly want to upgrade the boost controller, etc. So be sure of what is included in the used price, you might realize its not as killer of a deal as you thought.

Red03SillSS Posted February 19, 2007 Author Report Share Posted February 19, 2007 It comes with an intercoolers and my tuner said he will tune it. As for the price i am getting it for, I am doing some work trade off, I am doing a complete custom paint job on his truck and hes giving/installing the STS. The truck will take me abou a month of hard work to get it complete, but I will have an STS when I get done. Should I do this or not? Kit might even have a bigger fuel pump. I comes with a ton of stuff. Quote Link to comment Share on other sites More sharing options...
Chevrolet SS Posted February 19, 2007 Report Share Posted February 19, 2007 I love work trade off's I would be all over it sounds pretty complete and your not paying install. plus no out of pocket money Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted February 19, 2007 Report Share Posted February 19, 2007 I would go for it in that case. I've done work trade offs myself. Jus tbe careful because his item is tangible and yours is not. Make sure he isnt too picky with your work no matter how good of a job you do. But thats between you and him.

ShakinLM7 Posted February 19, 2007 Report Share Posted February 19, 2007 Just to let you know I am by no means experienced or very knowledgeable when it comes to hands on experience with forced induction. I have been reading as much as I can find and I hope to decide on my first set up and install it on my truck soon. There was an STS Turbo for sale locally so I went to check it out. It was installed on a 2003 SS , the guy said it was running 5lb's of boost. He had the intercooler upgrade, the GT65 Turbo upgrade, and a programmer ( I believe it was a predator ) After going for a ride I was not impressed! I was expecting to find myself pined back in the seat. That was not the case.... I honestly think my truck would be pretty well matched with his. I have a short bed, 2x, regular cab, internally stock 5.3 lm7, 4l60e, K&N, functional shaker hood, (Recently gutted Cats) with Cat Back Borla duel exhaust, and a hyperteck 3 power programmer. Maybe his truck is just worn out and tired but he had receipts showing that the kit was only 6 months old. I personally hope that his set up just wasn't tuned correctly because I really like the idea of being able to pop the hood and have no sign of F/I.

Black2003SS Posted February 19, 2007 Report Share Posted February 19, 2007 Thats the point about the STS...the numbers are all over the board. One guy runs 14.0 with a base kit, another runs 13.0...someone put on an intercooler and lost .3 tenths...tuning issues...the list goes on and on...they are very tempermental. Its not like a radix where you slap it on and go run 13.0 like everyone else with similar mods. Just make sure he gets it right. I think STS's have huge potential, but have yet to be 100% proven. Some over on performancetrucks.net have alot of experience with them, but they arent doing anything more special than any blower out there. You might want to ask over there as mroe of them use the STS than here. Quote Link to comment Share on other sites More sharing options...
haynss Posted February 19, 2007 Report Share Posted February 19, 2007 good luck it will get a little bothersome because just as mentioned above #s are all over the place. I have a 12# spring in right now but never see more than 7.5#s. Im a little baffled by this but for what it is not there is a lot of power when she kicks in.

Do you have the base model kit other than the 12# spring or do you have upgrades? Quote Link to comment Share on other sites More sharing options...
chpspecial Posted February 19, 2007 Report Share Posted February 19, 2007 The Gt67 should boost up to 7.5# with no problem,, at least mine did. When I put the intercooler I did loose about 1.5 pounds but I picked them back up with teh cam I installed. With a proper converter you can boost off of the line an run just as good as teh radix people. Tuning is a big thing and if they are not tunned right it will cause them to not run right, hence they wont pinn you to yoour seat. My truck does AWD drifts and burn outs if I hit it hard enough.

SSThunder Posted February 19, 2007 Report Share Posted February 19, 2007 Sounds like a good deal since no money out of your pocket. I'm a radix fan myself since I first rode in a radix powered LQ4. It had much more than the basic kit but it did throw me back in the seat. I just installed my radix last week and I pretty much love it. It's the stock 3.3 pulley(5lbs boost) but it runs good. I've got a shift kit and Trailblazer torque conveter(2600 stall) so it takes off like crazy. Feels like the front end comes up a little. I'm still running the stock tune so I know it will get better. I say go for it, just cover your @ss enough in the work you do for the guy. Have a friend with you when you 2 agree on the terms or have it in writting. Good luck Quote Link to comment Share on other sites More sharing options...
Red03SillSS Posted February 19, 2007 Author Report Share Posted February 19, 2007 Did even better. Haha I had 2 friends with me. Quote Link to comment Share on other sites More sharing options...
twistedsnails Posted February 20, 2007 Report Share Posted February 20, 2007 I don't have an sts but it sounds like a good deal depending on what your time is worth...if the kits got the intercooler, I'd run 10lbs with 60 pounders and the 255l pump and make sure you've got it tuned right or you will be re-building your motor, cuz you will be rebuilding your transmission either way guarenteed..

Red03SillSS Posted February 22, 2007 Author Report Share Posted February 22, 2007 It has the intercooler. Not the fuel pump or injectors. If I run on say 6# of boost, do you thin kmy tranny would be ok? givin my current mods. Quote Link to comment Share on other sites More sharing options...
