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.

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.

Application: Honda/Acura K-Series
MSRP: $60 shipped anywhere in the continental United States
Contact: / 240.490.7173

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.

Application: Honda/Acura: K-Series
MSRP: $328

Application: Honda/Acura K20/K24
MSRP: $850
Contact: / 510.440.1605

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.

Application: Honda/Acura K-Series
