JUN Machine Shop has added some engine parts for Honda K20A engine. We added a Hyper Piston Kit, I-Beam Connecting rods, and Billet Crank shaft. Now they are on sale.

This Hyper Piston Kit could much reduce piston weight by reconsidering piston profile. Reducing weight of piston effects response improvement of engine. And, a load to the bearing is reduced.

We prepared two kind of piston, a Hyper Piston Kit, and a Hyper Piston Kit EX which is light weight more. We believe you can get more good feeling on the NA engine by these pistons.

The JUN connecting rod is made by shaving in order to pursue lightness and strength, this form has no futility. The material of a connecting rod is used SCM440. And connecting rod bolts are made by ARP. If big end is transformed at the time of high rotation, a metal will burn. In order to prevent the phenomenon, it was made the form which distributes stress.

This crank shaft is an excellent product in the strength balance rate, same as our stroker kit which is big popularity in the world.
