Getting the Most From 91 Octane Pump Gas with a Honda K Motor, Part Three

Drag Cartel, accept no substitutes!

The ARP ground washers are placed over the studs and the nut side is lubricated with ARP assembly lube before the nut is added.

The nuts are torqued down in sequence in three steps up to the factory torque value.

Next, the Drag Cartel Stage IV cams are readied for installation.  They have been WPC treated for long life and low friction.

The rocker assembly is coated in pre-lube and set in place on the head.

Additional pre-lube is added to the cam journals.


  1. I am relieved You didn’t use the ARP main studs mentioned in Part One of this build.
    That would’ve been total overkill on that power level.

    In my previous life, I used to work for a motorsport shop that built rally, rallycross and circuit racing K-series engines among other things.
    On NA builds with limited budget (which most of them were), we reused OEM Honda main studs up to 4 times, even head studs were reused up to 3 times.

    Only difference was, they were always torqued to a specific value with a certain type of lubricant.

    And not one time did we have a problem with bolts backing out or losing tension. If a headgasket did blow, it was always due to severe knock or overheating.

  2. This looks like it’s going to be a fun package! What kind of power and torque is expected? Will engine speeds remain about stock?

  3. Using WPC on the camshaft is beneficial on a Honda’s B series as well since these engines don’t have a bearing on the followers like the K series.

    Looking forward to seeing what Motoiq does with the transmission of the RSX!
