STS Turbo System

[RaceLegend79]

OK, so I cant afford it yet but if you knew me youd know that I always plan ahead and get as much info as possible. You should see me at election time. Anyway I have seen these Squires systems and really seem to like them. My only draw back that I can see is that it seems that a lot of people have blown motors after installing these systems. Since I am trying to do this next year I wonder if anyone thinks that before we have forced induction on our cars that they have forged internals first? BC if that is the case I have to do that first then the following year get FI. I know it is better to build a motor and do the FI at the same time but there is no way my wife will allow that. Any help would be appreciated. Thanks all.

get a 03 cobra motor.............like me

[Todd]

Not a requirement but would help if you are going to crank the power up at all. I blew my motor on what I thought was relatively low power.

But if you can put on one of the factory kits and not jack with the boost you should be fine as long as your tune is right.

Are the Cobra internals different than ours?

[VAmarauder03]

Ditch the cobra shortblock and follow todds footsteps and get an MMR short block....They build the shortblock according to how you want to make power(turbo, blower, nitrous,N/A) and their StreetMod 900 block will hold 900hp and it only cost 2800$, now im not 100% on what you guys are paying for a 03 cobra shortblock but that sounds hard to beat....

we have a MACH I engine not a cobra engine...MACH I engines have no forged internals, the 03 Cobra has a forged interals and is capable of holding very high boost and hp numbers, where as the MACH I engine doesnt handle it quit so well

[sicilianmarquis]

^ ditto thats y i say, but im going to look into this MMR you guys are talking about, i do getemployer discounts from ford so thats why im so keen on it, and plus for s bone stock motor they can hold up to like 900 horses, on all stock internals( look at youtube "turbo cobras" videos" its been done before

[MarauderSM]

03-04 Cobra engines are said to be safe up to 1100hp. This was in 5.0 Mustangs and Muscle Muscle Mustangs. 1100hp on a all stock internal engine is pretty amazing but I can believe it. The modular motor was built to handle forced induction power adders. This is the same thing I wondered whether to purchase a Cobra long block or aftermarket engine. Cobra long blocks are pretty pricey I think $9k. Look on karkraft.com

I've heard of two people using this system. One is SlickVik03? He has a single STS kit on a 2V motor and is making decent power. Aonther car I've heard of was a DOHC transplant into a vic. He had a lot of trouble with the boost blowing apart the tubes. Search around and you should find both of thier stories. SlickVic can be found on hardcore50.com in the power adder section.

tubes?witch tubes? if it was his tubes from his setup- then thats just ****ty craftsmenship or bad silicone connectors

Yes I did research and the one that kept blowing up tubes is what concerned me, that was the one that had the 4v. But what confused me was that the 05 Mustang GT worked just fine. Does it not have 4v also?

please trust me when i tell you that 900 hp turbo stang on "stock shortblock" either wasnt truely on a stock shortblock, or it didnt last terribly long...ford put a bad ass engine in these but i have a hard time seeing it hold 900hp for any amount of time...besides ive seen them blow at much lower numbers than that...

the new mustang have a 3 valve engine

[MarauderSM]

They couldn't have been talking about the cobra block blowing at 900. There has to be hundreds of people using that block with at least 700 at wheels. I still stand by 1100 on this block.
Also you can check on crownvic.net on the turbo vic. I think he know switched over to a 5.4l.

[VAmarauder03]

block and shortblock are two diferent things....ive seen it first hand...at the same time dont get me wrong...ive seen them hold 700hp to the wheels also but for how long is the real question...some blow up and some hold it, just like some of us get the factory freaks that run 13's with little mods and some run 14's with more mods...i unfortunately fall under the slower category lol

[RaceLegend79]

Now there I can at least say Im lucky bc mine did run a 14.2 but it was redlighted so I had to estimate time based on car that ran with and beat me by little less than quarter car(Pat's MM) ran 13.9. Mods= K&N drop in, FM 40s, & high flow cats.

Legend,

Our short blocks are good to 450 HP and something like 6500 RPM. If you drop a SC or Turbo on a stock motor, you will be making all your power below the motor's redline, and as long as you don't crank it up too much, should not be above the power limit for the powdered metal rods.

TALK TO LIDIO. He has put so many hard miles on stock bottom ends, they do not brake as a rule, UNLESS YOUR TUNE IS TOO AGGRESSIVE. If you spark knock one of these motors WITH a power adder, you are asking for trouble. Folks who use NOS seem most likely to have issues like this.

It's just not a problem if you do it right. RPMs are WAY MORE DESTRUCTIVE than HP on a bottom end. You will make peak power at 5500 RPM. You have nothing to worry about as long as you have conservative ignition timing and a mixture that is a little bit rich.

Put the Turbo or SC on, and ENJOY!:beer:

You have a Marauder engine. We were first with this design. I have this arguement with Mach 1 owners all the time. What was first, the chicken or the egg. The O3 Cobra motor has more then just forged interanls. I think Mike is pushing over 500 rwhp with a piston and rod change only to the stock Marauder short block.

any more details???as i would like to know the diference so when i try to explain this to someone that i dont look like a jackass...could you not be pushing over 500rwhp in a mach 1 with rods and pistons? hopefully i dont come across sounding like a jerk i am just trying to learn somethin new

Vehicles using the aluminum 32-valve DOHC 4.6 include the following:

1993-1998 Lincoln Mark VIII, 280 hp (209 kW) and 285 ft·lbff (386 N·m)
1995-1998 Lincoln Continental, 260 hp (194 kW)
1997-1998 Lincoln Mark VIII LSC, 290 hp (216 kW)
1999-2002 Lincoln Continental, 275 hp (205 kW)
2003-2004 Mercury Marauder, 302 hp (225 kW) and 318 ft·lbff (431 N·m)
1996-1998 Ford Mustang, Cobra, 305 hp (227 kW) and 300 ft·lbff (407 N·m)
1999/2001 Ford Mustang, Cobra, 320 hp (239 kW) and 317 ft·lbff (430 N·m)
2003 Ford Mustang, Mach 1, 305 hp (227 kW) and 320 ft·lbff (434 N·m)
2004 Ford Mustang, Mach 1, 310 hp (231 kW) and 335 ft·lbff (454 N·m)
2003-2004 Ford Mustang, Cobra, Supercharged, 390 hp (291 kW) and 390 ft·lbff (528 N·m)
2003-2005 Lincoln Aviator, 302 hp (225 kW) and 318 ft·lbff (431 N·m)

While there are LOTS of 4.6L 32v motors out there, there are only a couple that are directly related to Marauder.

03/04 Mach1 Long Block - Cams are a different grind, Upper/lower intakes are different, and pulley assy is different.

and...

The Lincoln Aviator... Again, Cams are a different grid, upper/lower intakes are different, and the pulley assy is different.

The aluminum 01 Cobra motors and earlier are different blocks and to my understanding not the same castings.

For those considering using the Marauder motor or trying to replace a blown one, that's pretty much the relevant info...

Back in mid 2002, when the Aviator and Mach I (which share our engine) were scheduled for release, they were held up at STAP for a correction related to the cylinder heads. Early MMs did not get this correction, but all Aviators and Mach I's did. Exactly what that correction was, I don't have at my finger tips, but there was a splash about it at the Blue Oval News site, and it was valve/head related.

03-04 Cobras have an iron block. I think about 40lbs heavier but able to withstand a lot more power due to the strength of the iron. A seriously blown Maruder should use a iron block.

[Bradley G]

The Marauder block is not keeping you under these thresholds safely.
It is the rotating assembly that is the weak link.
Our Marauder block is much lighter than the 03-04 cobra blocks, by 70-80 pounds.

For those of us in Texas I found a shop that has put these systems on cars and said that they wouldnt charge me an arm and leg to install and they can upgrade the bottom end of the motor with a tune on the install. But I have never heard of it and I used to hang out with a bunch of Mustang friends when I was closer to Houston. The name is Lightning Force Performance.com. so if you know of them I would definatly be intrested on info or any other input thanks.

FYI: shipping weight of an aluminum block is 134 lbs.
Iron block shipping eight is 178

[Bradley G]

The weight difference between iron versus aluminum is noticeable while driving.
Some of the "shipping weight" difference could be from packaging.
