The naturally aspirated 2.4 16v 4G64 is a common long-stroke build, pairing a 94mm crankshaft with 156mm or 162mm connecting rods. This category covers the forged pistons machined for that combination, by WISECO, WOSSNER and JE PISTONS, plus the OEM-size tri-metal bearings: ACL Race Series for the crankshaft and connecting rods, KING RACE for the crankshaft, connecting rods and thrust washers.
The 2.5 8v 4G54B is a niche naturally aspirated block: this page carries a single active reference, a forged piston by WISECO built for this engine. There is no wide range here, unlike the 4G63 or 4G64 blocks in the same family: that is simply the real state of this less common engine. No big end bearing or head gasket reference is listed yet for this block at NSB Concept. Check the exact bore and specification before ordering.
The 3.0 24v twin-turbo V6 6G72T is covered here on two fronts. On the cylinder head, 7 valve references: 5 by SUPERTECH (Inconel and black nitrided stainless, intake 35.50 or 36 x 6.57 x 106.35mm, exhaust 31.50 or 32.50 x 6.54 x 105.5mm) and 2 by FERREA stainless +1mm. On the bottom end, OEM-size ACL Race Series tri-metal bearings for the crankshaft and connecting rods, forged pistons, and a reinforced ATHENA head gasket.
The naturally aspirated 3.8 24v V6 6G75 is a niche page: only one active reference is listed, a forged piston built by WISECO for this block. Unlike the twin-turbo 6G72T in the same family, which carries seven valve references and several bearing brands, the 6G75 has no bearing, connecting rod or head gasket reference yet at NSB Concept. Check the exact specification before ordering this reference.
The 3000 GT is Mitsubishi's twin-turbo, all-wheel-drive GT coupe, built around the 6G72T V6. This page carries the same engine parts stock as the 6G72T engine-code page, minus the forged pistons: SUPERTECH and FERREA valves for the cylinder head, ACL Race Series tri-metal bearings for the crankshaft and connecting rods, and a reinforced ATHENA head gasket, for rebuilding or reinforcing this generation's top and bottom end.
The Mitsubishi Lancer Evolution IV (CN9A chassis, 1996-1998) was the first Evo to receive the 4G63T engine in its 7-bolt execution, kept through to the Evo IX. This page groups the bottom end for that block: KING RACE tri-metal main and big end bearings, OEM size, thrust washers, in both 4G63 and 4G64 (long-stroke build) specification, plus forged 7-bolt connecting rods available from several brands (MANLEY, ZRP, BOOSTLINE, WOSSNER). Stock is shared with the 4G63 7-bolt engine code page.
The Mitsubishi Lancer Evolution V (CP9A chassis, 1998-1999) widened the cylinder head ports of the 4G63T 7-bolt block inherited from the Evo IV. This page groups the cylinder head: SUPERTECH black nitrided stainless steel intake valves in four diameters (34.00 / 34.50 / 35 / 36 x 6.57 x 109.6mm) and a SUPERTECH INCONEL sodium exhaust valve, 31.50 x 6.54 x 109.6mm, plus KING RACE bearings and thrust washers in 4G64 size for a long-stroke build. Forged 7-bolt connecting rods, shared across several Evo generations, complete the rotating assembly.
The Mitsubishi Lancer Evolution VI (CP9A phase 2 chassis, 1999-2001) keeps the 4G63T 7-bolt block from the Evo V. This page groups the rotating assembly and head sealing: ARP cylinder head studs for 4G63 from 1994, ARP Hi-Perf 8740 connecting rod bolts, an ATHENA reinforced head gasket for 4G63T, KING RACE bearings and thrust washers in 4G64 size, plus forged 7-bolt connecting rods shared across several Evo generations, available from several brands (MANLEY, ZRP, BOOSTLINE, WOSSNER).
The Mitsubishi Lancer Evolution VII (CT9A chassis, 2001-2003) received a new body and chassis while keeping the 4G63T 7-bolt block. This page groups reliability parts for sustained use: KING RACE main bearings and thrust washers in 4G64 size, an ATHENA reinforced head gasket, ARP cylinder head studs for the 4G63, 2002-2006, SUPERTECH intake and exhaust valves, and forged 7-bolt connecting rods shared across several Evo generations.
The Lancer Evo 8 (CT9A) carries over the 7-bolt 4G63T block from earlier Evo generations. Only 5 active references here: forged connecting rods for forged pistons in MANLEY, ZRP, BOOSTLINE and WOSSNER, KING RACE crankshaft main bearings and thrust washers at OEM size (catalogued 4G64 Evo V-IX), and an ATHENA reinforced head gasket for the 4G63T. A narrow range, most of it shared with the other 7-bolt Evo generations.
The Lancer Evo 9 (CT9A MIVEC) carries the same 7-bolt 4G63T core: forged connecting rods in MANLEY, ZRP, BOOSTLINE and WOSSNER, KING RACE crankshaft main bearings and thrust washers at OEM size (catalogued 4G64 Evo V-IX). It adds an ATHENA reinforced head gasket and a pair of CATCAMS 48-tooth adjustable cam pulleys, specific to the Evo IX. 6 active references, mostly shared with the neighbouring Evo pages.
The Lancer Evo 10 marks a generational break: the CZ4A chassis drops the cast-iron 4G63 of the Evo 4-9 for the all-aluminium 4B11T. This page groups the valvetrain and bottom end of that new block: SUPERTECH valves (black nitrided stainless intake, INCONEL exhaust) and mechanical cam follower, ACL Race Series and KING RACE bearings at OEM size, and ARP fasteners (main bearing bolts, head studs, flywheel bolts, con rod bolts). Its stock is that of the 4B11T engine-code page.
The 4G15 is the 1.5L 16v turbo fitted to the Mitsubishi Colt CZT and its Ralliart versions. This page carries a single active reference: ZRP forged connecting rods for forged pistons, available with ARP2000 or L19 bolts depending on the build. Forging gives the rod its fatigue strength under sustained boost, where the OEM part is the usual failure point. A niche page, with a catalogue narrowed to this one product because the 4G15 covers a single, small-capacity model in our range.

Q: What's the difference between a 6-bolt and 7-bolt 4G63 for a high-performance build? A: The 6-bolt (Evo I-III) has a stronger crankshaft, ideal for 600hp+. The 7-bolt requires reinforced MANLEY H-beam connecting rods and 85.5mm WISECO pistons. For both versions, ARP L19 studs and ACL Race bearings are essential beyond 450hp.
Q: How do you prepare a 4B11T (Evo X) for a reliable 500hp daily driver? A: Optimal setup: forged JE PISTONS 86mm pistons, ZRP Pro I-beam connecting rods, SUPERTECH dual springs, 0.8mm COMETIC gaskets and KING XPG bearings. This base handles a constant 1.8 bar with a matching turbo and remap, ideal for mixed road/track use.
Q: Is the 3000GT's 6G72T V6 worth investing in forged parts for? A: Absolutely. With low-compression WÖSSNER pistons, MANLEY connecting rods and CATCAMS camshafts, this twin-turbo V6 easily exceeds 600hp. The robust cast-iron block architecture handles extreme power levels, making the 3000GT an ideal base for ambitious projects.
