Con'rod is the weak point of 4B11 engine. Upgrading of con'rod is required for performance enhancement.

HKS developed "Forged I-Beam" connecting rod, which is "Strong" and "Affordable".


POINT-1
"Strong and affordable" is the concept of the "Forged I-Beam" Con'rod
  • I-Beam was selected for 4B11. It is strong and affordable with "high grade chromium molybdenum steel", "carburizing heat treatment" and "fracture splitting manufacturing for the big end".
  • Although it looks like stock part, it is strong enough for high performance tuning vehicles.
H-Beam connecting rod
  • Although it is strong against torsion, it is hard to absorb torsion.
  • Lighter weight than I-Beam for the same strength level.
  • Shaving process is more and expensive. (For high performance vehicles.)
 
I-Beam connecting rod
  • Although it is used for mass production vehicles, even Formula 1 engines use this shape.
  • Although it is weak against torsion, I-Beam absorbs it.
  • It is heavier than H-Beam. Easier production.
  • As explained above, H-Beam and I-Beam have their own merits and demerits.
POINT-2
Fracture splitting manufacturing method, which has high connection rigidity, for the big end
  • Fracture splitting has higher connection rigidity than normal knock pin type as the contact surfaces are more since they are uneven.
  • Although the looking is not good, since they are connected with uneven surfaces, it has great rigidity as shown in the pictures below.
POINT-3 Strength for more than 500ps
  • Tested on an engine bench with GT3240 Full Turbine Kit without any problem.
  • HKS Forged Piston (21003-AM003) is recommended.
