This page brings together the cylinder head parts listed for the HONDA 1.8 16V R18Z1 of the Civic X FC6. All four references are SUPERTECH and share the same 5.5mm stem diameter. The valve stem seals are sold in sets of 8, separately for the intake (VS-H5.5I-8) and for the exhaust (VS-H5.5E-8), so only the side being worked on needs replacing. Valve collets complete the range, in kits of 16 or 32 depending on how many valves are removed. No pistons, connecting rods or head gasket are listed on this page.
The parts gathered here cover the HONDA 1.8 16V R18Z1 of the Civic X iVTEC FK5. SUPERTECH is the only brand listed, across four references with a 5.5mm stem diameter. The valve collets come in two pack sizes: a kit of 16 pieces for eight valves and a kit of 32 pieces for sixteen valves, that is a full cylinder head. Valve stem seals are available alongside them, in sets of 8, in an intake version and an exhaust version. This page carries no bottom end parts and no uprated studs or bolts.
This page brings together the engine parts listed for the HONDA 1.5 turbo L15B7 of the Civic X Coupe 170HP. The bottom end is its core: forged pistons are offered in two bores, 73mm and 73.5mm, and in five compression ratios from 9:1 to 12.5:1, from JE PISTONS, WÖSSNER and WISECO. The low ratio suits a build running high boost pressure, the high ratio a lightly tuned engine. ACL RACE and KING RACING thrust washers complete the bottom end, while cylinder head parts and uprated studs and bolts are also listed here.
The HONDA 1.5 turbo L15B7 of the Civic X Coupe 177HP is served here by a full cylinder head range from SUPERTECH. The performance valves are sold in sets of 8, separately for the intake and the exhaust, with a 5.5mm stem diameter matched by the valve stem seals and the valve collets, the latter in kits of 16 or 32. Uprated valve springs come in sets of 16. Forged pistons in 73mm and 73.5mm, ARP studs and bolts, and crankshaft thrust washers are also listed on this page.
For the HONDA 1.5 turbo L15B7 of the Civic X Coupe Si FC1 205HP, uprated ARP fasteners take first place: head studs and con rod bolts, the two parts that govern how a boosted engine holds together before any increase in boost pressure. Crankshaft thrust washers are available from ACL RACE and KING RACING. The page also carries forged pistons from JE PISTONS, WÖSSNER and WISECO in 73mm and 73.5mm, along with the SUPERTECH cylinder head range. Forged connecting rods, however, are not listed here.
The HONDA 2.0 turbo K20C1 of the Civic X Type-R 306HP is served here by two families of parts. Forged connecting rods are offered by BOOSTLINE, whose three-pocket I-beam saves weight without losing stiffness, and by WÖSSNER, whose version uses a conventional I-beam. The choice comes down to the power target and the budget, both ranges being supplied complete with their bolts. ACL RACE and KING RACING thrust washers complete the page. No forged pistons are listed here.
This page covers the HONDA 2.0 turbo K20C1 of the Civic X Type-R FK8 310HP. What separates the two BOOSTLINE forged connecting rods offered here is not the beam, identical three-pocket I-beams, but their bolts: the standard version uses ARP2000 bolts, the uprated version CA625+ bolts, reserved for the most extreme builds. WÖSSNER completes the offer with an I-beam fitted with ARP2000 bolts. ACL RACE and KING RACING thrust washers are also available on this page.
For the HONDA 2.0 turbo K20C1 of the Civic X Type-R FK8 320HP, crankshaft thrust washers are offered in two brands, ACL RACE and KING RACING, both without surface coating: they take up the crankshaft end float and are replaced every time the bottom end is opened. BOOSTLINE and WÖSSNER forged connecting rods complete the page. No forged pistons, no head gasket and no head studs are listed for this version.
