I know the size is the same as far as the diameter goes but has anyone actually tried to build an engine with the 3000GT Pistons?

ENGINETECH P45476

MAHLE/CLEVITE 224-2375

Looks like the quest compression height is 1.385" vs the 3k of 1.256"
I'm not doing the math, but I'd say it's low on compression for a 2.6.

Ok awesome, I don't have enough experience with engine internals to do the math, are those the turbo 6g72 pistons?

the NA is

with a compression height of 1.26. still way low.
I love Rockauto for the plethora of information it contains.

I don't have the data to calculate that, but I'd guess under 5:1.
