Performance engine parts for the BMW 523i E39 2.5 24V M52B25, single VANOS, built from 1995 to 1998.
This is the only Series 5 E39 page carrying the 2.5 rotating assembly: WISECO forged pistons from 84.0 to 85.0mm at an 8.8:1 compression ratio with a 22mm gudgeon pin, and ZRP forged connecting rods with an I-beam and a 140mm centre to centre length, with ARP 2000 or L19 hardware. It is also the only one with ARP main studs, fourteen pieces in 8740 steel. The single VANOS head brings together CATCAMS Sport camshafts and cam followers, SUPERTECH and FERREA valves, SUPERTECH guides, valve stem seals and collets in 6mm, and an ATHENA O-ring or COMETIC MLS head gasket.
Performance engine parts for the BMW 523i E39 2.5 24V M52B25TU, double VANOS, built from 1998 to 2000.
The head is complete: CATCAMS Sport camshafts 1304402, 1304405 and 1304406 for the double VANOS M52, SUPERTECH and FERREA valves, SUPERTECH guides, valve stem seals, collets and springs in 6mm. The bottom end is limited to ACL RACE and KING RACING tri-metal bearings. The ZRP forged connecting rods on this page have a 135mm centre to centre length and are listed for the M20B25, M50B25, M52B28, M54B30 and S52B32: the 140mm length of the M52B25 sits on the single VANOS 523i page. No forged piston and no head gasket are listed here.
Performance engine parts for the BMW 525i E39 2.5 24V M54B25, built from 2000 to 2004.
The ZRP forged connecting rods for the M54B25 use an H-beam in 4340 steel, as a set of six or as a single rod, with ARP 2000 or L19 hardware: that is what sets them apart from the I-beam rods of the M52 blocks. The ATHENA and COMETIC head gasket covers the M54B25 and M54B30 in 85.0mm MLS, from 0.69 to 1.52mm thick. The head is complete: SUPERTECH and FERREA valves, SUPERTECH guides, valve stem seals and collets, SUPERTECH and CATCAMS springs in 6mm, with ACL RACE and KING RACING tri-metal bearings. No forged piston and no camshaft here.
Performance engine parts for the BMW 528i E39 2.8 24V M52B28, single VANOS, built from 1995 to 1998.
This is the best stocked page of the Series 5 E39: WISECO forged pistons from 84.0 to 85.0mm at 8:1 and 9:1 compression ratios, ZRP forged connecting rods with an I-beam and a 135mm centre to centre length, a set of twelve ARP con rod bolts and fourteen ARP main studs in 8740 steel. The single VANOS head takes CATCAMS Sport camshafts and twenty-four cam followers, SUPERTECH and FERREA valves, SUPERTECH guides, valve stem seals and collets in 6mm. The ATHENA and COMETIC head gasket is listed for the M52B28 without TU.
Performance engine parts for the BMW 528i E39 2.8 24V M52B28TU, double VANOS, built 1998 to 2000.
The rotating assembly is complete: WISECO forged pistons from 84.0 to 85.0mm at 8:1 and 9:1 compression ratios with a 22mm gudgeon pin, ZRP forged connecting rods with an I-beam and a 135mm centre to centre length, and a set of twelve ARP con rod bolts shared with the M54B30. The double VANOS head takes CATCAMS Sport camshafts 1304402, 1304405 and 1304406, SUPERTECH and FERREA valves, SUPERTECH guides, valve stem seals, collets and springs in 6mm, with ACL RACE and KING RACING tri-metal bearings. The uprated 2.8 head gasket is listed non-TU and does not fit this block.
Performance engine parts for the BMW 530i E39 3.0 24V M54B30, built from 2000 to 2003.
The three litre takes WISECO forged pistons from 84.0 to 84.5mm at 9:1 and 11:1 compression ratios, with a compression height of 28.32 to 30.32mm, ZRP forged connecting rods with an I-beam and a 135mm centre to centre length, and the ARP con rod bolt kit it shares with the M52B28. The CATCAMS Sport camshafts 1304501 and 1304504 are specific to it, and the ATHENA and COMETIC head gasket covers the M54B25 and M54B30. SUPERTECH and FERREA head parts in 6mm, ACL RACE and KING RACING tri-metal bearings in standard, +0.025, +0.25 and +0.50mm.
The M62B44 is the 4.4 litre V8 of the BMW 540i E39, built from 1996 to 2003, and our selection for it comes down to four parts.
The JE forged pistons open the build: a 92mm bore, an 8.5:1 compression ratio, a 22mm gudgeon pin, and a fitment table that also covers the 740i and X5 4.4i. The set of sixteen ARP con rod bolts and the uprated ATHENA head gasket, references 330026R and 330027R, close the bottom end and the head seal. Valve timing goes to the CATCAMS Sport camshafts 1303702. Let us also say what this page does not carry: no forged connecting rod, no bearing and no valve is listed for this block to date.
Parts for the S62B50, the 5.0 32V V8 of the BMW M5 E39 built from 1998 to 2003.
Two parts only, and both of them aim at the connecting rod. The ZRP forged rods use an H-beam in 4340 steel, in a set of eight, with ARP 2000 or ARP L19 hardware; they are listed for the M5 E39 and for the Z8 E52, which share this block. The ACL RACE and KING RACING tri-metal big end bearings come in standard size, in standard with HX clearance and in +0.25mm. This page carries no forged piston, no head gasket and no valve to date: if you are building an S62B50 and need a part that is missing, ask us for it.
