Re: Eaton Swap.....
 

I am currently collecting parts to start my eaton swap and I ran into an 03-04cobra ecu and was wondering if any of you guys run the cobra computer or if it doesn't really matter what you use.

Re: Eaton Swap.....
 

most run the stock with a tune

Re: Eaton Swap.....
 

Can anyone clarify something for me about the alternator wiring. I thought I did it right but read something earlier that has me questioning it.

I took the factory plug and the new plug and basically oriented them so that the clip was on the top (the release clip) and then swapped over the two outside wires.

In one of the write ups it was stated they should be reversed. Of course the pigtail from Ford is all black wiring so it's not like I could even attempt to match wires from the two.

Also what did everyone do for the return spring on the throttle body? From what I could see most left it off.

I finally got the last few things I needed. I have to still take care of the IAT2 plug, figure out the vacuum lines (without EGR and related sensors), build my dual FPDM harness and drop in the GT pumps.

The guy at the dealer told me to just cut my plug and extend it. He said it was the same plug.

Re: Eaton Swap.....
 

started mine up today after loading the new tune,but things did not go well my gt pumps were wired in reverse so tank had to come back out,fixed that got tank back in after checking everything started up and run fine till i had to shut it down,my brand new 3.2" alt pully went to pieces,center hole in the pully is about an 1" big now,order a new 1 and sent the old 1 to the machineshopto be fixed,might get it back tomorrow fingers crossed:anger:

Re: Eaton Swap.....
 

Actually they are reversed.

Re: Eaton Swap.....
 

ok thanks, where did everyone get the EGR Delete cap that gos on the exhaust? made a plate but need the cap now.

Re: Eaton Swap.....
 

cut tube off pinch it off ,then weld the tube where it is pinched

Re: Eaton Swap.....
 

where are you guys hooking up the water pump for the intercooler? also i read that you need to use the mach 1 gasket for the oil cooler but ive found that the mach and cobra have the same part #. needless to say i have a horrible leak. any ideas?

Re: Eaton Swap.....
 

Get the cap right from your local Ford dealer.
You mean the intercooler pump? I have mine wired so it comes on when the ignition is on.

ya. what did you wire it to though. i tried using the wiring for the egr crap that i deleted but couldnt find anything with enough voltage. keep blowing out fuses.

Re: Eaton Swap.....
 

i ordered it from lethal performance.

Re: Eaton Swap.....

Re: Eaton Swap.....

Waiting on a friend to help me bleed the brakes tomorrow then it's just a few lose ends. I'm hoping to drive it to work Wednesday. I have a base tune in it so I can drive it but it's going to need to hit the dyno before I take it WOT and work out the idle (it's at 1k in the video) and turn off the EGR.

Re: Eaton Swap.....
 

sounds great hope you get it there soon,can,t wait to get mine dialed in ,to see what it can really do

Re: Eaton Swap.....
 

I got to drive mine for the past few days and so far no problems. I still need to get it tuned, should be one night this coming week. Now I'm wrapping up the little things. Since I nearly got stuck in the rain without the shaker back on I made brackets and got it mounted.

What I basically did was remove the bottom pan since it would have to be cut up to really clear the blower pulley. I made a new lower pan from a thin piece of 12"x18" aluminum, then mounted some aluminum rails on it and some 1/8" x 1" aluminum flat stock mounting tabs for the sides and front. Once I got it right I cleaned it up, cut out a few holes to push air down on the Eaton and painted it black hammer tone. I'm not too worried about the rain that actually makes it into the shaker.

Re: Eaton Swap.....
 

Wow, nicely done! Cool bracket you made up there. Looks great!

Re: Eaton Swap.....
 

I know this has probably been asking a million times, and may even be in this thread. But could somone give me a ballpark estimate of what it would cost to S/C a mach, and have a built motor to handle the boost and hp. Is about 9k close?

Re: Eaton Swap.....
 

less than that if you buy a complete cobra motor,more if you want to go overboard

Re: Eaton Swap.....
 

If you are budget minded, take your time, buy some parts used you can do the eaton swap and build an engine for $5-6k. However if you are paying labor $9k easy and that price you might just be better off looking for a stock Cobra engine and sell your stock Mach engine to offset the cost.

Re: Eaton Swap.....
 

No the only labor I have to actully pay is if I wanted build a motor, I know how it works, and I know enough to get me out of trouble or help someone. But I would pay the labor to have a pro. build me a motor. But I was thinking aswell that I could find a used Cobra motor and drop it in, then do a KB swap or such. I can do all of the myself, my only labor $'s like I said will be if I have to go build a motor. And If I go that route, from just glancly reading about Cobra's, the 04 motors are the best ones right, and it should be a direct swap into my car I assume, except I may need a wiring harness?

I know there a KB and Whipple thread, but If I got my hands on a good running cobra motor, what kind of prices is it to swap on a KB or whippe, another 2-3k?

Thank you!

Re: Eaton Swap.....
 

I pick up a 98 Mark 8 motor and i was lookin over some of the parts and i noticed the IAC Valve looked the same as the cobra and the part number looks to be the same. The IAC Valve only has 9f715 on it and thats the same as the cobra so could anyone tell me if it will work?

Re: Eaton Swap.....
 

anyone?

Re: Eaton Swap.....
 

yes

Re: Eaton Swap.....
 

9F715 is the "base" number. All that tells you is that it's an IAC valve. You need the numbers in front of and after it to verify it's the same part.

Should look like F78A 9F715 AB

That's the engineering number. With that a dealership can cross the number over to a Ford part number.
