Whats the difference between an suv 4.6 and a mustang 4.6?

[SilverBullet00]

I happend to notice a website selling a 4.6 SUV motor w/ 600 miles on it for a good price. I know it has an aluminum block and puts out 232 hp, 290 ft lbs of torque. What makes that motor have less power than the mustang? Is it all in the cams? I was possibly thinking about picking it up and sticking my stage 1 cams in it with an aftermarket intake and long tubes, but would I be loosing power? or is there some other modifications I need to do to the motor to give it more power?

is it a pre 1999 or after? If it is 99 and up it will have the PI heads (good) The only differance I know of is different cams and different ECU both optimized for better low end. Mechanically, they are the same.

explorer?

I believe the only differance is the intake on it (its set up for more torque then HP rating)... cams should be the same, i know the F150 engine that i got had the same cams in it, the crown vic also has the same cams..

 

[SilverBullet00]

Crap, I guess its from an explorer- but i dont know what year it is. The intake looks the same as it does on the mustang....

If it's a PI engine then just swap the cams and intake from your car,and enjoy the 80 lbs less weight.

Just to get things strait......all 4.6L Explores are PI engines. On top of that, they've got the same cams and intake as the Mustangs does as well. The difference in horsepower comes from the single exhaust and tune of the ECU. The Explorer engine swap is very common among the T-Bird/Cougar crowd.

There it is- that helps out a lot! What about the ECU... What would work best with it? anything?

Then he should just bolt in his Stage 1 cams and go!!

It should work perfectly with your stock ECU. Just swap your parts over to that motor and it should be exactly the same powerwise and tune wise.

Can I pull the motor and reinstall the new motor with long tubes on? If I do this im also going to either repair my headers or go with a set of stainless steel headers.

I have never pulled a motor before, is it very hard?

Isn't the Explorer air filter on the opposite side? (I haven't looked at one in a while).

No, it's on the same side. Same motor, but I know my 04 explorer with the 4.6 in it is drive by wire. So you'd have to swap over the tb and linkage and stuff.

It depends on the kind of headers you've got. Some will come out with them on, others need to be removed from the head first. My Cougar was a real bitch to pull (twice ), but I was able to do it without removing the headers.....but they're Kooks mid-length though. The MN12's are notably tighter under the hood though.

 

[SilverBullet00]

well I have bbk long tubes, and I can tell you the heads wont pull out with the headers still attatched- tried to do that this summer when I was replacing a head gasket. I wish I would have just done this swap then. Anyways, does $1895 sound like a good price for the motor?

Their is also something different about the throttle body's
on the Explorer's that is different from the mustang.

 

[SilverBullet00]

yea, it might have the electronic throtle linkage on it, but I can swap those out with my current components.

Again, back to the computer- my computer will work even though this is a romeo motor and I have a windsor?

 

[1Bad96]

1895 sounds kinda high for a stock explorer motor

yes.

 

[Duke309]

what exactly is the benefit of doing this swap other than getting a lower mileage motor?
