Evo 123 - CP Pistons - 4G63 Forged Piston & Ring Set (85.0mm / Standard) - 6-Bolt
CP-Carrillo forged pistons and rings, 85.0mm standard bore — 6-bolt 4G63
The standard-bore set: 85.0mm, the same dimension the 4G63 was built with. Order this one when the machinist has measured the block and confirmed the cylinders are still within spec, so you get forged strength without sending the block out to be bored. It is the most direct route to a built bottom end, and it keeps every oversize step your block has left in reserve for a future rebuild. The pistons are forged from 2618 aluminium and machined for forced induction, with the ring pack, wrist pins and locks included so the set is ready to hand straight to your engine builder.
- Bore: 85.0mm — the standard 4G63 bore, no overbore required
- Forged 2618 aluminium alloy
- CNC machined and balanced, with custom skirt and barrel profile
- Accumulator grooves and double pin oilers for forced-induction durability
- Includes CP-Carrillo high-performance ring set, wrist pins and locks
Fits:
- Mitsubishi Lancer Evolution I (CD9A, 1992–1994)
- Mitsubishi Lancer Evolution II (CE9A, 1994–1995)
- Mitsubishi Lancer Evolution III (CE9A, 1995–1996)
Cut for a 6-bolt 4G63 with a 21mm wrist pin. That is the swapped short block used in a lot of early Evo builds; if yours is the factory 7-bolt, this is not the set you want.
