BMW 525i E34 192hp M50B25TU (with VANOS) 1992-1996

Uprated engine parts for the M50B25TU of the BMW 525i E34, the VANOS version built from 1992 to 1996. Two figures separate it from the earlier block: the ZRP forged rods measure 140mm centre to centre instead of 135mm, and the forged pistons are WISECO only, from 84 to 85mm at 8.8:1 or 11:1. The VANOS timing takes its own CATCAMS camshafts and cam followers, and this page also carries uprated valve springs in SUPERTECH and CATCAMS. The head shares the rest with its sister page: SUPERTECH and FERREA valves, guides, 6mm stem seals and collets, COMETIC or ATHENA gaskets and ARP fasteners.
