Much better than stock.



1. that seems awfully cheap.... actually so damn cheap i would run away from it... at that price i can't see them being anything but cast.


2. why am i under the impression that our OEM pistons are sinter forged.... or is that just the rods?


Hypereutectic - much better than stock, but no not forged.

They can support 400HP without a problem. That safely covers all but the baddest of the bad. It's also a significant upgrade over stock and for cheaper than stock. Price was an issue!

So go run away and leave them to the rest of us...

2. umm... That's just the rods. The Stock pistons (2.5L & 3L) are simple cast. Not hypereutectic.
The SVT pistons may be hypereutectic??? Anyone know for certain?



OK, not to drag this up from the dead......

BUT ( ), I have a balanced 3L with 90mm Speed Pro pistons w/ about 9.75:1 CR, stock rods, upgraded tri-metal bearings, accusump, ect. With War pushing for the limits on OEM pistons, what is a reasonable target for my 3L as far as boost? (I have a Garrett T3/T04E .57/.63 BTW)

I'm breaking in @ 3.63 psi now, but once I'm able to crank up the boost..... is 12 psi within reason for my street tune?

(I realise this is more of a FI question, but this was already in the database and is in need of updating some of the info within)
