naplesZ Posted February 10, 2005 Share Posted February 10, 2005 I was looking in a truck magazine a while back and they did a install of a new turbo kit that mounted the turbo in the back of a trunk by the muffler. Has anyone heard of this and what's your opinion. Quote Link to comment Share on other sites More sharing options...
Guest Magnum Rockwilder Posted February 10, 2005 Share Posted February 10, 2005 Squires Turbo Systems, STS. You should be able to find their website with video clips via Yahoo search. I have no opinion about the mounting position. Quote Link to comment Share on other sites More sharing options...
jvanen Posted February 10, 2005 Share Posted February 10, 2005 Actually met the guy who does some of those out in utah. Currently doing a Supercharged Henassy Viper that is currently cranking 800 and change on Hp. Which is just frickin sick! I heard he won some award down at sema for like best new product.... or something like that. when it comes to mounting the turbo in the back by the Axel they say an intercooler isn't needed with all the cooling properties of the Air and oil lines going back to it..... which makes you go hmmm....... My question is, mount it in the trans tunnel or near/above that rearend? Quote Link to comment Share on other sites More sharing options...
Kazuya1274 Posted February 11, 2005 Share Posted February 11, 2005 This brings back some memories! Memories of a turbo kit for a 4th gen. Z28 or Trans Am... That mounted the turbo in the rear. The claim of not needing an intercooler because of the long turbo pipe was also there. Try doing a search for Squires Turbo. It was discussed pretty thoroughly, as most controversial topics are.

Clifton Posted February 12, 2005 Share Posted February 12, 2005 I think it would be good ONLY if there was no posible way to fit the turbo in the engine compartment. An intercooler would still be needed if you want cooler air. Tubing does little to disipate heated air moving at 300 ft/sec. Quote Link to comment Share on other sites More sharing options...
Len Posted February 12, 2005 Share Posted February 12, 2005 Reason they don't use an I/C is basically same reason they didn't install one on our Z's....they don't run very much boost since it is basically built for a stock engine...on the TA or Camaro I believe they are running 3 to 5lbs. of boost. Higher than that I/C are available. Quote Link to comment Share on other sites More sharing options...
tannji Posted February 12, 2005 Share Posted February 12, 2005 As Kazuya noted, the STS system got a lot of air-time, very controversial for a while. It is not the best setup for a 1/4 mile car, but like most any other setup, with a mix of accessories and technique, it performs decently.... just doesn not have the best 60 around. There are a LOT of F-body, Y-body and Chevy/GMC trucks running it with some rather amazing track times. (for trucks) While it is designed to run at low PSI with no additional cooling, the dramatic difference in intake temps with an IC would make me go with an IC unless the car just had no room at all for it. The thing that impresses me is that I have yet to hear from an owner who doesnt like it. Some will admit that there are better setups for the track, but that seems to be its worst criticism. It is at its best in a vehicle that needs a little (or a lot, lol) of oomph, but also needs to keep its manners in day to day driving. One owner has his F-body with STS in the 700 to 800hp range, and it is every bit as scary as that level of power suggests.... apparently he tested it for the first time with his wife in the car.... and she doesnt like it all that much.... apparently had somethign to do with dramatic and sudden loss of traction at 80 mph...... In a Z, we have the room to do a standard turbo install on a V8, but the STS in stock configuration would be a little cheaper and a lot easier to install, right up until you get around to routing the exhaust and intake plumbing. I dont believe you could do it on a stock chassis. For those of us planning on some extensive mods, like 240SX rear suspensions, fuel cells, ect... it could work. One of the things I like about it the most is a simplified engine bay, and a lot less heat under the hood. Quote Link to comment Share on other sites More sharing options...
tannji Posted February 12, 2005 Share Posted February 12, 2005 Little update, this guy with a 94 chevy truck (6000+ pounds) just ran a 1.7sec 60, and 11.99 @110mph, on the STS with 5 pounds boost. He is going to put on some taller, stickier tires, and install IC, and go do some 10 pound runs. Oh, that 1.7sec 60 was with the truck trying to go sideways.... lol.... imagine trying to launch that setup in a Z. Quote Link to comment Share on other sites More sharing options...
Len Posted February 12, 2005 Share Posted February 12, 2005 If I remember right the setup for a Camaro runs around $3,800....part of the reason why people like it so much is because its so user friendly. The package you get...you could install in an afternoon....Try that with just running I/C piping on our Z's.... Quote Link to comment Share on other sites More sharing options...

savageskaterkid Posted February 13, 2005 Share Posted February 13, 2005 i check this site all the time- its http://www.ststurbo.com- the coolest thing about it is that u don't need to run a muffler-so u get all the cool sounds of having a turbo and BOV. and its COMPLETLY street legal.

olie05 Posted February 13, 2005 Share Posted February 13, 2005 I saw some of the install pictures on their website and noticed how low to the ground the turbo is... and more importantly the air filter. What happens when you go through a big puddle? -Oliver Quote Link to comment Share on other sites More sharing options...
tannji Posted February 13, 2005 Share Posted February 13, 2005 it hasnt caused much of a problem for anyone yet, but they have some sort of filter that help prevent any damage, not to mention fabbing a shield for it. Quote Link to comment Share on other sites More sharing options...
savageskaterkid Posted February 14, 2005 Share Posted February 14, 2005 i've put much thought into that kit, and i think im gonna do it-im gonna make a skid-plate type thing for the turbo and filter so that way rocks won't mess with it 100 posts!!!!!!!

tannji Posted March 16, 2005 Share Posted March 16, 2005 A 2004 GTO just ran 10.6 on a STS kit, not bad for a 4000 pound car. Quote Link to comment Share on other sites More sharing options...
Guest 73LT1Z Posted March 17, 2005 Share Posted March 17, 2005 I'm in the process of adding this type of setup to my '95 Trans Am solely due to lack of engine bay room. I had an ATI in there, but the loss of cooling capacity sunk me. It amazes me how "controversial" this layout is- there are people on the other forums I belong to that go out of their way to knock STS- and they don't even have a blower or turbo!

caen fred Posted March 18, 2005 Share Posted March 18, 2005 How do you route the oil line on such a set-up? Is there enough pression to run back the oil? Quote Link to comment Share on other sites More sharing options...
Guest 73LT1Z Posted March 18, 2005 Share Posted March 18, 2005 The oil feed is taken from a 1/8 pipe fitting above the oil filter (same place the supercharger guys get it) and run back to the turbo. I'm using braided stainless steel hose on each end of 3/8" aluminum tubing for the feed, and hose on each end of 1/2" aluminum tubing for the return. An electric pump takes the drain oil from the turbo & pushes it back to either the valve cover (STS setup) or the oil pan (I had a fitting here from my supercharger install).

caen fred Posted March 18, 2005 Share Posted March 18, 2005 What kind of spec does your pump have? Do you monitor the pressure? Quote Link to comment Share on other sites More sharing options...
Guest 73LT1Z Posted March 19, 2005 Share Posted March 19, 2005 What kind of spec does your pump have? Do you monitor the pressure? It is a Melling #10555 high volume pump, ? as to the specs exactly (believe a stock SBC pump is rated at 7 GPH). I have not completed the install but do not plan on installing a pressure gauge for the oil feed line. Quote Link to comment Share on other sites More sharing options...
