Stock Forged Pistons?

ktmfly1 · May 22, 2005

My friend was telling me that the stock 87-93 mustangs had forged pistons and other forged parts it it. Is that true?
thanks

87- Late model year '92 had forged. they then switched to hypereutectic pistons.

They do as well. He was just answering the question that was asked.

Agreed.

The 87-93 engines are otherwise all very similar.

You very, very well could be correct. I dont have experience with 4 eyes and only corrected the end point in the range that KTM posted (he started out with the aero foxes).

EDIT: oops - this will teach me to load a page and then feed the dog. I was just a little late in replying; everyone beat me to it.

I think I remember reading somewhere that if you had a Grey oil pan you had forged pistons and if it was Black oil pan you had the Hypers. Dont know how accurate that is though.

I believe I have seen the same thing -- but I do not know how accurate that is as well. Seems silly to just change the color of an oil pan for different pistons.

Daggar · May 23, 2005

Somebody once told me a great way to remember which color goes with which pistons. It seems that I've forgetten how to remember that. LOL

They may have been changing who was supplying parts to them at the same time and it just so happens that the oil pans changed around the same time the pistons did.

[wipes tear from eye, reminds himself that no one listens to him].

Dags, it might have been me. My mnemonic device for that is that Grey is good , and black is bad (relating to the color of oil pans).

That's it! Now... if I could only remember who it was that told it to me. Hmmmmmmmm......

So does this mean my 90 came with Forged pistons????

1Bdazzstang · May 24, 2005

I once read in one of the mustang magazines that if your mustang has a grey oil pan, it has the forged pistons. If the oil pan is any other color, they are hypereutectic.

Guyfoxbody · May 24, 2005

I have never heard of the oil pan color thing. From what I have been told is all '87-'92 5.0's have forged pistons. '93 hyper's. It was a cost cutting measure in '93 to turn more of a profit. I also think the '93 Cobra's had hypers too.

crunchie12268 · May 24, 2005

93's have hyper...... damn

In late model year '92, they switched to hypers. The switch to hypereutectic pistons was also for oil control and NVH.

Unless the owner had to change engines due to minor mishap and he swaped the original grey oil pan onto the hyper pistoned 93 engine.

Plus they cut costs!
