These pistons are tried and tested by some serious engine builders pushing the limits of reliability and have reached over 750 bhp with this exact EJ20 turbo piston.

The Mahle brand piston is well known for its piston technology and in this case they have used their knowledge from Formula 1 engine technology to produce a piston with some unique features.
Forged from a low silicon 2618 alloy

Very light weight

Low friction wasted skirt and coated for high rpm reliability

Pressure balance groove below top ring designed to balance the pressure on the top compression ring and there for restricting blow by and power loss

Very resistant to ring land problems unlike the standard factory piston

Forced gudgeon pin lubrication via the oil ring drain holes so keeping the pin well oiled and cooled--this is essential for major bhp

These forged Mahle pistons will support 800 bhp depending on the crank-rods and head bolts used and more important the fueling and ignition timing etc

If you want 4 forged pistons with rings and pins that are ready to fit to standard length rods and standard stroke crankshaft then these are perfect
