if it were a hyper the part # would be h4579p.

get some spiral wristpin retainers"thumbs up
or at least spin those wire retainers so that the gap is facing up or down not side-to-side like in picture one

still no idea as per what brand ?
it's from a 2.5 & the only # is the H579P

does the skirt look a little thicker than normal ?

doesn't look hyper too me, looks like a cast replacement

He gave you your answer. They are Hyper.

Looks to me like it's H579P (although the H looked like a 4 at first).

The "S" shield is for Silvolite, I think.

If you do research.. Silvolite is the KB brand FOR hyper-pistons. If its Silvolite, its Hyper. Hope this helps

Actually, Silvolite pistons are not all hypereutectic.

hypers=piece of junk for TDs,,I have about 3 broken sets in a box, 1 set was installed by an engine genuis, without me knowing, each set will last until you hammer it a few times..

any idea what the difference between the H4579P & the H579P is ? are these both Silvolite #'s ?

(I keep hoping these are NOT hyperutes, as that would mean I am in need of a set of 30 over 2.5 pistons)

FOR SALE: 4 matching ashtrays....:big grin:

You better start looking for new pistons, then, as they are indeed hypereutectic.

Might be Speed-Pro (Federal Mogul) instead of Silvolite, though.

153 89-92 ALL TURBO 2.5
FEDERAL MOGUL H579P

LAMETEC hit it nail on the Head
it's a federal mogal "speedPro" hence built by silvolite ..yes hyper piston and is JUNK in a none stock turbo car
