3.0L 12v - RB30 with RB25DET cylinder head

The RB30 with an RB25DET cylinder head is not a factory engine but a well-known build: the tall 3.0L 12-valve block takes the 24-valve RB25 head, gaining stroke without losing breathing.

Two active references here, and we would rather say so than pad the page. The WOSSNER forged pistons cover 86, 86.5 and 87mm bore at 7:1 and 7.1:1 compression ratio, sized for boost. The MANLEY forged connecting rods come as H-Beam and I-Beam Heavy Duty, with ARP2000 or ARP8740 bolts, listed for the RB30 of the Skyline R31.
