I just interested in what type of pistons are in my engine if eneyone knows? are the turbo pistons? like different from normally aspirated engines or that hyperdermics or whatever (4g63bt engine) please help a bro.

i think the turbo ones are stronger i think the whole motor is stronger not %100 but i am pretty confident

when taking my gsl engine out, i found my pistons have a very raised top on them. Come up almost a 1/4 inch fromwhat i rememebr. Being a 1.8 engine, what are the chances of gettign them into a 4g62? obviously valve clearence will need to be checked etc. Those raised top style pistons give hgiher compression dont they?

the type of pistons in your engine are the standard ones

why do you want to know, you arnt puttin GSL pistons in a GSR are you.


Hypereutectic piston
From Wikipedia, the free encyclopedia

Hypereutectic pistons are cast internal combustion engine pistons made from aluminum with over 16% silicon content for strength and durability. The term 'hypereutectic' comes from eutectic. Special melting processes are necessary to ‘supersaturate’ the aluminum with additional silicon content. Special molds, casting and cooling techniques are required to obtain finely and uniformly dispersed silicon particles throughout the material. This produces pistons that are very hard, thus brittle. They have proven to be un-forgiving with engine knocking. For this reason they are great in naturally-aspirated engines, but should be used with caution for 'nitrous', super- or turbochargers. Generally speaking, forged pistons are a better choice for high boost.

Hypereutectic pistons are used in many original equipment engines. They are favored because of reduced scuffing, improved power, fuel economy and emissions. The reduced thermal expansion rate allows the piston to be run with reduced clearance, which reduces losses due to gases escaping past the sealing rings.

I want to know because I know my car is a turbo but if my pistons are standard are they like specifacally made for a turbo car like different and much more stronger then a normaly aspirated engines pistons?

i think they r stronger out ov a gsr turbo

if your car is turbo it has fuggin turbo pistons in then, i would say they are diffrent to gsl ones, are trying to be dodgy and put n/a pistons in there

yeh... I wouldn't go putting in GSL pistons if you don't know! Why does it matter anyway??? Usually you can simply change the rings on your current pistons, unless you've stuffed a conrod or something... You should have Turbo Pistons from the factory!
