Is anyone using mahle pistons and rods in a ej257? thinking of getting some for my new build. having a md321t and hoping around the 450/450 mark.
are these up to the job?

 

we have mahl pistons and manley rods in a 2.5
its recently been mapped by JGM and was found to have a weak wastgate actuator and would loose boost, we made 430 and JGM says with a new actuator we will see approx 480 MAHL=no problems its a well known piston manufacturer

 

Mahle are a good make.
