i HAVE A SPARE JDM VTEC RESIVOIR PM ME

Dang, that blows. Gotta hate it when you run out of VTEC fluid. You should try to get that JDM reservoir from DonkeyPunch, I heard they hold more fluid than the POS USDM one.

ok so i gotta queston what is the main difference between forged pistons and hypereutectic type pistons i have googled it and still dont understand the main difference besides the way they are made (sorry if i am ranting still waking up)

Hijacker

hypereutectic is just talking about the alloy that pistons are made of. Aluminum expands faster than iron when heated up, so most companies add silicon to the alloy composition to better restrict the expansion and prevent binding in the cylinder bore.

Forging is a procedure to make pistons. Just know that forging is better than casting and can usually tolerate more abuse.

Hypereutectic pistons are an alloy with higher silicon content than standard cast pistons. They're stronger and lower thermal expansion than standard cast pistons. Forged pistons are stronger, and more expensive. For what you're doing, there really isn't any reason to spend money on forged pistons because you'll never need the strength.

If you're just doing a mild rebuild, why aren't you reusing the stock pistons?

i niced a slight crack in the number 3 piston and i dont want it to get worse so i thought it would be a good idea to replace them all while im this far into it.

Hijacker

There's only one way to keep a crack in the piston from getting worse. The trash heap.

If you want stock performance, toss in a set of OE pistons and call it a day.

Fabrik8

There are huge amounts of used stock pistons out there for cheap for single cam engines, so try that route before buying new ones. Unless you're planning on changing compression ratio or bore size, etc...

or stop messing with shitty hondas.

alright i was just curious on the differrences

this just be a daily i got a 1998 f150 that is the projectt
