Lead Photo By Aaron Bonk

If you don’t already have Part 1 of this guide go pick up the latest Honda Tuning on newsstands now. In Part 1, our office coworkers gave you a guide of K-Series swap parts, so you could drop a K20 or K24 in just about any Honda. With the swap out of the way, we are here to supply you with Part 2, a guide that takes it a step further and helps you build up your K-Series. We didn’t forget about you guys who already have cars with K-Series engines either. You obviously don’t need Part 1, but Part 2 is going to get everyone’s K-Series going balls the wall.

01 Full-Race ProStreet Turbo Kit

Based around Full-Race’s legendary turbo manifold design, this kit is engineered to offer the ultimate in performance and reliability. Full-Race uses proprietary robotically welded stainless steel along with low entry angle merge collectors to create a free flowing and highly efficient exhaust path into the turbocharger. The K-Series ProStreet turbo kit can support power levels from 300 whp up to an over 700 whp monster while retaining all accessories, such as P/S and A/C. This kit comes standard with a 44mm Tial wastegate and 50mm Tial BOV. Every turbo kit is hand-fabricated in the United States from forged eight-gauge stainless steel, robotically TIG welded, and comes with a limited lifetime warranty.

04 Skunk2 Pro Series Intake Manifolds

Skunk2’s Pro Series intake manifolds for Honda’s K-Series engines feature larger plenums and shorter, oversized runners when compared to the RBC, and are cast with thicker wall material, leaving room for further porting for high-horsepower applications. Pro Series manifolds were designed for the “street enthusiast” who wants more power, but doesn’t want to sacrifice midrange performance to get it. The results are improved airflow, an enhanced venturi effect, and both midrange and top end power gains. Skunk2 offers applications for all K-Series engines, which are compatible with OEM throttle bodies as well as those as large as 76mm.

06 TODA Racing Anti G-Force Oil Pan

Toda Racing’s Anti G-Force pan was designed to help prevent oil from moving around under extreme conditions, which could cause a drop in engine oil pressure. The Toda oil pan’s design also keeps air from mixing with the oil, and for ease of serviceability, the main baffle plate is removable, making it easy to clean when overhauling. An extra service hole is provided to simply install an additional oil temp sensor and more.

07 BluePrint Racing K-Series Oiling Modification Kit

The BPR cam cap oiling modification kit eliminates oil starvation and camshaft seizure by routing oil externally to the number four and five cam towers. Seizure has been known to occur on stock engines due to lack of proper oiling and is becoming more common with use of aftermarket valvesprings with greater seat pressure or engines that see high rpm use.

23 BluePrint Racing Oil Pan Baffle

The BPR oil pan baffle was designed with the benefits of trapdoor baffling at a fraction of the cost of a complete oil pan. The BP oil pan baffle extends deep inside the oil pan, essentially dividing the pan into thirds, keeping oil from moving from one side of the pan to the other during hard corning. The larger of the two cells is centered around the oil pump pickup, keeping it fully submerged during hard cornering and/or aggressive driving.

29 Jun Auto Valveguides

Tuned engines can get hotter and have a much higher mechanical load over stock valveguides due to high rotations possibly damaging the valveguides. The Jun Auto racing valveguides are manufactured with a raw material, phosphorus-bronze, for increased strength and heat conduction to avoid any damages from the high rotation of tuned engines.

32 Okada Projects’ Plasma Direct

The Plasma Direct ignition coil has a high-power amplifier built into it. These produce four times more spark energy than stock coils and also generate an ultrafast multi-spark discharge of up to 10 sparks at higher rpm. Ignition spark amperage is increased 100 percent, therefore accelerating the ignition and combustion process. This is extremely important in forced-induction applications, but also improves the performance of normally aspirated engines.

39 Quaife Torque Biasing Differential

The Quaife Torque Biasing Differential was designed to improve traction in front-wheel-drive drag-race applications by reducing the torque bias ratio, or the side-to-side torque “difference” between the two axles. By design, the Quaife will never fully lock, making it advantageous for putting equal power to the ground through both axles, which reduces torque steer and speed scrubbing corrections. The Quaife differential uses helical-cut gears, so you can still run it on the street without issue, and is made from high-quality billet gear steel, making it maintenance free, and it’s backed with a lifetime warranty.
