The low-compression sibling to HKS's stroker range, this 1.75L L-Comp Step 3 full kit is built for big-turbo, high-boost GR Corolla engines. A billet full-counter crank stretches the stroke to 95.7mm for 1,746cc, while the lower-compression 88mm forged pistons give the headroom to run serious boost safely. It ships as a complete, balanced bottom end with crank, rods, forged pistons, rings, and pins.
