B8 exhaust ports...
Posted: October 21st, 2008, 10:20 am
Someone has got to know this... I'm trying to see if the B8 16 valve SOHC has the same exhaust ports as the BP DOHC... Found some information that suggest this is true, and from looking at varius websites pictures of exhaust mani gaskets, it seems they are the same.
Straight from wiki:
B8
The 1.8 L (1839 cc) B8 is not just a bored and stroked B6. Rather, a new block with widened cylinder spacing. The bore is 83 mm and the stroke is 85 mm. This SOHC engine was used in various Australian Mazda 323s and the American 1990-1994 Mazda Protege. It came in both 8 (B8-E) and 16-valve variants (B8-ME).
The B8ME is also found in Canadian variants of the 323 hatchback.
BP
The 1.8 L (1839 cc) BP is a dual-overhead variant of the B8. It was first found in the 1989 Mazda Familia and American-market 1990 Mazda Protege LX. This engine was dubbed BP-ZE and featured a forged crankshaft, piston oil squirters, an aluminum baffled oil pan, and Variable Inertia Charging System (VICS). This particular variant can be found in the following vehicles:
