I use wiseco as well cop ratio 8:1 , 81,5 bore.
make sure you have enough space for the oilsquirters.
I had to bend my for clearence
otherwise good quality.

I would never use those pistons. It´s not the manufacture, it´s the style. These pistons are for non turbo engines.
I would never use "slipper" pistons on a turbo.
Bearing problems are the simplest you will get.

Just my 2cents.

can you elaborate on this.

Be interested to know the pros and cons. I get the general idea but fancy delving a bit deeper.

They look good to me they have accumulator grooves in them as well

they dont look like the wiseco's i got for FI for the 16v and i would have expected them to be about the same. mine were skirted a lot more.

im no expert on pistons though.

ok, I´ll try it.

Forged pistons uses a bigger bore. The piston has also a bigger gap to the left/right. This gap is responsible for grinding the rod bearing on the left and right side. I saw a lot of engines with this problem, ´cause the force on top of the piston will also push the piston to both sides. You can prevent this problem by pistons with a a bigger piston skirt. This will control the sway in the bore and a equal strength to the rod bearing.
Second way is to change the rod bearings every 5000km. The bearing look is horrible, trust me.
