Re: Eaton Swap.....
I ran a 3" upper and stock lower on a stage 4 Steggy ported Eaton. I made just over 12 psi of boost. It was good for 498 rwhp.

I'm probably going to put a stock upper on until I get the tune figured out then. |

1) I have a 2.93 upper on my 04 with the stock power. I've seen 12psi according to my Aeroforce gauge. That's with stock manifolds, Bassani catted X, and Stingers. Also my compression is only 8.5:1. Your higher compression might affect it as well. 2) I tuned my 04 myself. It's not really that hard. I've tuned a couple other cars as well. |

I'm hoping the tune won't be to hard to figure out. I'm using factory Cobra injectors & MAF, the only aftermarket parts are a CAI and cattless H pipe. I have the Lasota book and will be getting a base tune from Lasota. I'm still a few weeks out from the tune. |
Re: Eaton Swap.....
Opinions on whether you kind folks think it'd still be worth it to swap an Eaton into a low-mileage Mach 1?
I know parts and install cost plays a factor but seeing as how the regular '18 GT now makes 460 hp at the crank and the Hellcat, ZR1, ZL1, Demon and new GT500 all make 600-800hp, is achieving ~500 at the crank in an 03-04 Mach 1 still worth the price of admission? Just looking for a friendly discussion and opinion. I have a low-mileage Mach and am wondering whether an Eaton swap on an otherwise stock bottom end producing 450rwhp is even relevant or worth it anymore, especially when comparing it to the cars noted above. Thanks in advance. |

This intrigues me. I figured that the limit of what an Eaton swapped stock block Mach 1 can do would only barely tread water when compared to the powerful cars of today. I guess our cars being significantly lighter than some of those cars listed helps? |

First way - Eaton swapped my 40k mile 2003 Red Mach 1. Make over 470rwhp thru an automatic. With 4.10 rear gears, it was super fun to drive and would put bus-lengths on most "fast" cars from stoplight to stoplight. Cost came in under $5,500 for everything including Eaton parts, heat exchanger, return fuel system upgrade, full exhaust system, etc. Second way - I did a complete Terminator Cobra drivetrain swap on my 2003 Azure Blue Mach 1. Pulled the tired and knocking original Mach engine and dropped in a 50K mile Cobra engine, T56 transmission, IRS rear, and eventually put a Kennebell 2.6 supercharger and E85 return fuel system on it. It makes 700rwhp today. Cost came in around $10k for everything. Good luck. It's worth it.

Re: Eaton Swap.....
I very much appreciate you guys for responding - Thanks. I wouldn't have thought that an Eaton swapped Mach would be able to stay with the cars you mentioned nor achieve what you've appeared to have achieved with that setup. I appreciate the insightful responses and always love seeing pics of a Mach 1 :COOL:
I have also been told that the Eaton is both the best way to go as well as the worst way to go for supercharging. Two different shops in my area had very different opinions. One shop swore by going with a Vortech or Procharger and another says an Eaton is what I want as long as I'm not looking to produce huge numbers. Both shops are well respected and I have no doubt both do good work so I will not discredit either shop - it's just interesting to hear peoples opinions on the matter. :yeh: |
Re: Eaton Swap.....
My 498whp Eaton swapped Mach1 engine(in a GT) with 3.73 gears was enough to beat up on my buddy's 2012 GT with a 2.3TVS and another buddy's 2.2 KB 2004 Cobra. The newer cars are nicer, ride smoother, have more creature comforts but it comes at a price. They are quite a bit bigger and a lot heavier.
Since Eaton swapping mine, I went full tilt and now have a Whipple 3.4 on my built/forged 4V with a built 4r75w auto behind it. It makes 800+ to the tire and surprises a lot of "fast cars". To top it off, I love the look of the new edge Mustangs so I am sticking with mine for a long time. |

I'll say this...my father's last car was a Terminator with a VMP swap and supporting mods that was putting down 700+ on our local dyno, and I saw a Procharged Mach 1 pass it like it was tied to a tree one night. :??: I wouldn't have believe it if I hadn't seen it myself. With the Mach factory compression ratio and a well tuned centrifugal kit, you can pretty much wipe the floor with Hellkittens, ZL1s, whatever you want. |

So, Eaton it is. Now, I'm just hoping I can get to that conservative ~450rwhp mark. :eyebrows: |
Re: Eaton Swap.....
The Eaton that I'll be running is from a Cobra that had it ported/polished - with a stock bottom end in my Mach, what benefit if any will I be able to see in having this? Also, I'd like to know if most of you are running the stock sized upper/lower pulley's or what you've done with your setups.
Thanks in advance. |

Re: Eaton Swap.....
Bump from the dead. Just read most of this thread and I'm frothing at the mouth for 450rwhp.
I just picked up an 04 Oxford White 5-speed, 70k miles. Really wanting to do this swap. Being its almost 15 years since these cars came out, would it be ill-advised to begin this trek? Are some parts completely 100% impossible to find? |

If the car has already been modded and you just want to go further, keep in mind not only the initial costs and aggravations of what you're doing, the cost of supporting mods that need to be done to take good advantage of the new power, and the inevitable costs that will come as a result of the added power. For example- my transmission is making some pretty cool noises these days and will need attention. Probably sooner rather than later. You will find yourself on a never ending path of modding, maintaining, repairing etc. If these things sit ok with you, then by all means the eaton swap can be done and will be stupid fun. The parts are becoming more difficult to find and the install is much more involved than a centri setup. An eaton swapped Mach 1 will also be much more difficult to return to stock if you ever sold the car and needed to get more of your money back, unlike with a centri that can be taken off in just hours. How good you are at working on cars will be something to consider as well. What happens if you get in over your head? Are there shops near you that you can trust to save the day? Expect things to happen. They will. I would not advise going into something as serious as supercharging with a tight budget and without other means of reliable transportation. |

Of course as mentioned by user 311-420, your total expense and money dropped into the car is going to go up, but if making the car your-own is important and you plan to keep it, then go for it. That's just what I did! Haha! I can say I probably have the most expensive Mach1 with 114k miles on it. LOL. Ryan |
Re: Eaton Swap.....
Some parts are very hard to come by like the intercooler mounting brackets, oil cooler, and good caged lower pulleys but they can be found. If not, there are alternatives to use.
Like others have said, if you are comfortable with working on the car and are willing to take the time to find and install the right supporting/mods, go for it. The added power is like a drug and can lead to the never ending desire for more. Be aware, adding more power is a quick way to find the weakest component in the drivetrain or driver seat. |
Re: Eaton Swap.....
I did my eaton swap while ago, i used a stock size pulley and im pushing 426 rwhp and 396 ftlb tq. Everyone seems to be getting better numbers and im wondering if the guy that tuned it did a bad job because after the tune it was running lean so i installed a new h/o fuel pump and he tuned it with the iac valve disconnected. Am missing something? I have stock headers with a catback exhaust and just a drop in air filter. Maybe thats why?
|
Re: Eaton Swap.....
Dyno numbers are really only good for letting the tuner know whether or not the changes he's making are working or not. Having said that, your numbers sound right on to me considering the stock exhaust and (I'm assuming) a 91 octane tune.
Not sure why he wouldn't want to tune with the iac hooked up. Is it hooked up now? Did you switch to the cobra iac when you 'swapped? |
Re: Eaton Swap.....
Im not sure why he did that either, after hooking up the iac the pinging lessened quite a bit too so idk. and yes im running 91. My next mods are going to be headers and a cold air intake throttle body and another tune. Does anyone know of someone out here in southern california that is good?
