The 616.16 category holds the only active reference for the air-cooled flat-four of the Porsche 356 SC Coupe and Cabriolet (95bhp, 1964-1965): the WOSSNER K9015DA forged piston kit. A single listing, offered in three bore sizes, 82.5mm, 83.0mm and 83.5mm, matching three compression ratios, 9.5:1, 9.6:1 and 9.7:1, with a 22mm gudgeon pin and a 27.10mm pin height. This narrow range covers the usual rebore steps of the 616/16 engine without multiplying part numbers: a straightforward choice between standard and two oversizes, for a rebuild faithful to the original 356 engine.
The 901 2.0L category brings together the three bottom-end families for Porsche's very first flat-six, fitted to the 911, 911T, 911L, 911E and 911S from 1964 to 1969. The JE PISTONS and WOSSNER forged piston kit, rated for standard and oversize bores, 22mm gudgeon pin, 33.90mm pin height; the ACL RACE 6B2452H tri-metal big end bearings, shared with the 901 2.0 and the 911 2.2; and the ARP-204-4206 reinforced head studs, also rated for the 930 3.0/3.2 Turbo and the 964. This original 1964-1969 displacement does not yet have the MAHLE replacement cylinder, which only appears from the 2.2 engine onward.
The 2.2L 12V category gathers the bottom-end parts for the step up from the 901 2.0 to the 2.2 flat-six of the Porsche 911 (1970-1971), engine code 911/2.2. The JE PISTONS and WOSSNER JE-353223 forged piston kit, rated from 84mm to 89mm bore, 22mm gudgeon pin, about 34mm pin height, CR 8.5 to 10.7:1; the ACL RACE 6B2452H tri-metal big end bearings, shared with the 901 2.0 and the 911 2.2; and the ARP-204-4206 reinforced head studs, also rated for the 930 3.0/3.2 Turbo and the 964. A MAHLE 503WR1900 replacement cylinder is listed on this page: it is rated for the 2.4, 2.7 and 930 3.0 engines, not for the 2.2, so keep it for a rebore toward those displacements.
The 2.4L 12V category is the best-equipped air-cooled flat-six page in the family: six active references cover all four bottom-end families. ARP-204-6001 reinforced rod bolts (kit of 12) for the 911 2.4L/2.7L and 930 3.0L/3.0L Turbo; JE PISTONS and WOSSNER forged pistons for the 911 (1972-1973), engine code 911/51/52/53/57, 84mm bore, 22mm gudgeon pin, standard CR 7.5 to 8.5:1; ACL RACE 6B2455H tri-metal big end bearings in several sizes; CARRILLO forged connecting rods, H-section, WMC material. Also listed: a MAHLE 503WR1900 replacement cylinder and ARP-204-4206 head studs. The only page in the family where a full bottom-end rebuild stays possible without leaving the category.
The 2.5L 8v - M44 category gathers the parts for the Porsche 944, 924S and 944 Turbo 8v four-cylinder. The technical point specific to this page: two block natures, sleeved and Alusil, which dictate the piston choice. The 159161 forged piston kit (WOSSNER, WISECO and JE PISTONS) for the sleeved block, 100mm to 101mm bore, 24mm gudgeon pin, 40.80mm pin height, CR 7.5 to 10.8:1; and the 169845 kit (WOSSNER) for the Alusil block, same base bore sizes. Also listed: the ARP-204-4211 head studs and two COMETIC reinforced head gaskets, WC4272 at 100.5mm and WC4273 at 103mm. Against the 2.5 16v, which shares the studs and gaskets, this page stands out for its 8-valve head and the block choice.
The 2.5L 16v - M44/40 category gathers the parts for the 16-valve head of the Porsche 944 S (1987-1988, 190bhp EU / 187bhp US), engine code M44/40. The WOSSNER forged piston kit 160032 is dedicated to this engine: 100/100.5/101mm bore, 24mm gudgeon pin, 40.6mm pin height, 11.4/11.5/11.6:1 CR. Also listed: ARP-204-4211 head studs (944 2.5 8V/16V M44). Note: the COMETIC WC4272 (100.5mm) and WC4273 (103mm) reinforced head gaskets are coded for the 944 Turbo M44.50/M44.51/M44.52, an 8-valve engine. Against the 2.5 8v (M44), this page stands out for its 16-valve head and dedicated piston.
The 2.5L 24v - M96 category carries Porsche's first M96, the Boxster 986 (1996-1999, 204bhp EU / 201bhp US), engine code M96.20, and the switch from air to water cooling. A single active reference: the WOSSNER forged piston kit 169805, 85.5mm bore, 11:1 CR, 22mm gudgeon pin, 35.3mm pin height. Within this family's M96/M97 group, this page holds the smallest capacity, the only 2.5L, while the other pages carry the 2.7L.
The 2.7L 12V - 911 category carries the last evolution of the atmospheric 911 flat-six before the Turbo, engines 911/81/82/92/93/83 (T/E/S) from 1974 to 1977. Five active references: JE PISTONS and WOSSNER forged pistons 159473, 90mm bore, 22mm gudgeon pin, 8.0 to 8.5:1 CR; ARP-204-6001 reinforced rod bolts (kit of 12); ACL RACE 6B2455H tri-metal big end bearings in several sizes; CARRILLO forged connecting rods, H-section, WMC material; ARP-204-4206 reinforced head studs. Against the 2.4L (1972-1973), covered in block 1, this page stands out for its 2.7L capacity, the 1974-1977 end of series, and the absence of the MAHLE replacement cylinder.
The 2.7L 24v - M96 category carries the M96.22/M96.23 generation of Porsche's 2.7L, the Boxster 986 (2000-2002, 220bhp, then 2003-2004, 228bhp), before the switch to the M97. A single active reference: the WOSSNER forged piston kit K9569DA (169806), 85.5mm bore, 11:1 CR, 22mm gudgeon pin, 32.3mm compression height. The kit's own datasheet also covers the M97.20, but this page stays built on the M96, the original block of the 986 and the first-phase 987. Against the 2.7L 24v - M97, which carries the same reference, the distinction lies in the engine generation, M96 versus M97, not in different wording.
The 2.7L 24v - M97 category carries the M97.20 generation of Porsche's 2.7L, the one in the Boxster 987 (2005-2008, 240 to 245bhp) and the Cayman 987 (2006-2008, 245bhp), which succeeds the M96. A single active reference: the same WOSSNER forged piston kit K9569DA (169806) as the 2.7L 24v - M96 category, 85.5mm bore, 11:1 CR, 22mm gudgeon pin, 32.3mm compression height. The kit's datasheet also covers the M96.22/M96.23, but this page stays built on the M97, the evolution fitted to the Boxster 987 and the Cayman 987. Against the 2.7L 24v - M96, the distinction lies in the engine generation and the original vehicles, never in different wording.

For forged pistons for the 993, whose M64 engine is shared with the 964, see the dedicated engine code category: 3.6L 12v - M64.
The PORSCHE 911 type 996 category gathers engine parts for the first water-cooled 911 flat-six. It is the best-covered page in the group: it carries two specific ARP head stud kits, the ARP-204-4707 for the 3.4 naturally aspirated engine (M96) and the ARP-204-4210 for the 3.6 Turbo (M96 Turbo). It also lists the generic ARP-204-4206 kit, rated for the air-cooled flat-six engines (901, 930 3.0/3.2, 964 3.6), not for the 996. ARP is the only established brand on this page.
The PORSCHE 911 type 997 category covers the water-cooled generation that followed the 996, spanning two successive engine families, the M96 then the M97. It carries a single active reference: the reinforced ARP-204-4206 head studs, rated for the 901, 930 3.0/3.2 and 964 3.6 engines, but not for the 997. ARP is the only established brand on this page. For forged pistons for the 997, see the dedicated engine code categories: 3.6L 24v - M97, 3.6L 24v - M97 Turbo and 3.8L 24v - M97.
The PORSCHE 944 category is the best-covered vehicle page in the whole PORSCHE range, with four active references. The reinforced ARP-204-4211 head studs fit the 2.5 8V and 2.5 16V (M44) engines. Three reinforced COMETIC head gaskets complete the range, each rated for a specific bore: the WC4272 at 100.5mm for the 944 Turbo M44.50/M44.51/M44.52 (1985-1991), the WC4273 at 103mm for the same Turbo generation, and the WC4274 at 106mm for the 944 2.7 M44.11/M44.12 and 3.0 S2 M44.41. It is also the only four-cylinder vehicle page in the whole PORSCHE range. Each reference is available in several thicknesses.
