This page gathers the uprated engine parts we stock for the M54B25 straight six of the BMW Z4 2.5i E85, 192hp, built from 2002 to 2005.
ZRP forged connecting rods in 4340 steel with an H beam, as a set of six or individually, ARP 2000 or ARP L19 bolts included. On the cylinder head: ATHENA or COMETIC uprated head gasket, SUPERTECH and FERREA intake and exhaust valves, SUPERTECH guides, valve stem seals and collets in 6mm, SUPERTECH or CATCAMS valve springs. For the bottom end, ACL Race and King Racing tri-metal big end and main bearings, in standard size or oversize. The VIBRA-TECHNICS engine mount and the M22x1.50 oil cooler adaptor complete the range.
This is the best stocked page of the naturally aspirated M54 range: the M54B30 straight six of the BMW Z4 3.0i E85, 231hp, built from 2002 to 2005.

This page covers the N52B30 straight six of the BMW Z4 3.0 E85, 265hp, built from 2006 to 2008.
It is deliberately short: two references only, but the two parts that give up first once power goes up. The ZRP forged connecting rods in 4340 steel replace the standard rods, as a set of six, with ARP 2000 or ARP L19 bolts of your choice; the same set covers the 130i E81, 128i E82, 328i E90 and 530i E60, which share this block. The VIBRA-TECHNICS uprated engine mount, designed for the Z4 E85 and E86, removes unwanted movement of the drivetrain. No other part family is listed for this engine code to date.
The best stocked page of the whole Z4 range: the S54B32 of the BMW Z4M E85, 343hp, built from 2006 to 2008.
