Hi,

i will bulid my H22 (N/A) with Skunk2 Pro 1`s but i´m not sure about if i should use Mahle Gold Series with stock frm or Wiseco 88mm with iron sleeves?

Are the frm strong enough to handle the power and a rpm limit of 8200?
Or will i kill my engine?

 

u'll be fine with frm.

if u use the wiseco 88 mm...piston has a coating but it's still frm.

just make sure the machine shop u use if familar with frm

with being in germany..you should be fine..since porsche uses frm.

i have mahle 87.25 11:5 pistons in mine with pro1s and a (direct port) shot. not running yet..it'll move when done
