Engine difference with PP?

[jbailer]

Looking at the Ford parts, I see there is some difference in engines if it has a Performance Pack. Anyone know what the difference is (other than price)?

Interior upgrade, mostly suspension pieces, different wheels/brakes and 3:55 gears.

No he is referring to the ford part numbers for the engines. The are different and the one that says with PP is about $100 more. I found that point interesting as well. Wonder what the differences are.

that is interesting since all the other parts are the same.

There is a difference they list two different pistons and two different sets of piston rings on that parts list. News to me.

Found this is Ford changing pistons on us? I wonder if the pistons can be linked to the problem?

• Manufacturer: Ford

• Part: PISTON
• Replaces: EJ7Z-6108-B, EJ7Z-6108-C
• Part Notes: MKC; STD GRADE 3; 2.3L

I know the performance package cars have a larger radiator but I don't think I've heard any differences with the actual engine

Standard size and oversize on the rings

Different grades on the pistons is for different size bores. The difference in size of the pistons is very minor but they need to have multiple sizes based on how the block comes out of machining.

This is standard practice in OEMs. Including Subaru and Nissan.

Link doesn't work.

Robs link above works.

Without performance package has a block heater fitting to have it installed, with performance package has a plug there.

This is my guess, not 100%.

The block and short block are same.
The complete engine shows difference and probably one reason is sensors by oil for PP gauge pack.

Thanks! That's where I saw the difference but I couldn't find the parts brake-down between the 2 to see exactly what is different. How did you see that?

I wonder if the PP gets better pistons and rings or what is different about them.

Thanks Adam, I don't quite understand. Are you saying the bore size is different between the PP and non and the pistons and rings are just slightly larger for the PP? I though the bore was the same? Actually, didn't someone that can see the detail say the block was the same?

No, the difference we are talking here are .0001". When a block is machined for ford not all cylinders are exactly the same size. So they have different grade pistons to fill the hole with the correct piston to wall clearance.


The difference on the motor I believe to be the oil filter housing for the gauge input for the oil pressure gauge, or the adapter for block heater.
