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.
