2.5L 16v - EJ25 DOHC
The EJ25 DOHC is the only page in this branch where the cylinder head and the bottom end are prepared side by side. The head comes first: a Supertech black nitrided stainless intake valve, 36x5.96x105.9mm, given for the EJ25 2.5L and WRX, a Supertech inconel exhaust valve, 33x5.96x121.70mm, which its maker designates for the naturally aspirated EJ25 99-05, and the Ferrea Racing KT4019 kit of valve springs and retainers for EJ20 and EJ25 from 2001 to 2018. ARP M11x1.25mm head studs hold it down. Its own forged piston carries three names, JE Pistons, Wössner and Wiseco, in 99.5 to 100.5mm bores from 8:1 to 11.5:1, above KING Race and ACL bearings and ZRP, Boostline and Manley rods.
