HKS has expanded its lineup of G16E engine components with the release of the new G16E 1.75L LOW-COMP STEP3 CLOSED-DECK short block for the G16E-GTS engine.
The assembled short block features HKS’ BCD Piston Full Kit G16E 1.75L LOW-COMP STEP3 and adopts a closed-deck design to help minimize cylinder deformation under high combustion pressure. To compensate for changes in cooling water flow created by the closed-deck layout, HKS machines the water jackets for optimized coolant flow and adds an additional cooling water jacket around cylinder No. 2 for use with the company’s Grommet Head Gasket SUPER COOLING Pro.
HKS also machines the deck surface to improve flatness, performs cylinder boring to improve cylindricity, and thoroughly cleans the main oil gallery after machining to help reduce the risk of engine trouble.
The short block uses HKS machined low-compression BCD pistons, STEP3 high-strength machined I-beam connecting rods, and a machined chrome steel full-counter crankshaft. According to HKS, the connecting rods provide a 25 percent increase in strength over the OEM components while improving torque capacity.
The assembly also uses ACL main and connecting rod bearings, with HKS specifying the main bearings for excellent load capacity.
Displacement increases from the factory 1,618 cc to 1,746 cc through an 88.0 mm bore and 95.7 mm stroke. HKS notes that the factory balance shafts cannot be used with this setup and recommends HKS Racing Pro 10W50 engine oil.
HKS also recommends pairing the short block with its Grommet Head Gasket SUPER COOLING Pro and HEAD STUDS KIT Pro when building a complete engine package.
