Magnus Billet Honda K series K20/K24 Engine Block



The Magnus Dry Block and Billet RWD Pan can be seen in action on the Lucimar Racing Honda that is Currently Quickest RWD Honda in the world @ 6.19 sec @ 224 MP


The Honda K series block was originally designed to handle 300hp in Naturally aspirated format. Magnus developed the billet K series block to handle over 1700+ hp.

Originally developed for No water applications, but now available with water jackets for water cooling.

Magnus designed, and completely machined in house.  We start with a 6061 block that is machined to near finish size, then our rough block is heat treated and hardness tested to make sure it material has maintained T6 condition.  Once it is cleared the block is goes through a thermal stabilization process, we finish machine the external surfaces, finish machine for sleeves, install the Billet 7075 main cap and then precision line bore.  Internal grinding and clearance is not required to run aluminum rods up to 106mm crank with our aluminum perfect for All motor applications (up to 2.8L allowing less reciprocating weight on large stroke engines)

Block can be had in water jacketed applications, Lightweight or solid no coolant.  Finished solid no water block weighs 72 lbs roughly double the weight of a standard K and over 10 times torsional strength.  We specifically designed it to be heavy for use in RWD chassis cars and Sport FWD race cars, where weight on the nose of the vehicle is a priority.
