Does this engine is real bp from a 91-94 or is the OBDII from 95-98 with internal coil for the ignition?

Didn't the mazda bp 91-94 had a black valve cover, OBD-I, and external coil for the ignition?

looks like a 95+ BP

yeah! thats what I was thinking! Any other comments? Please HELP!

That looks like a newer BP (95up) But if it has a b6 stamp on it then its a b6 because I have a b6 and it looks like that, but then again the newer bp and dohc b6 look alike so check the block stamp!!!!

yes! I told the seller to send me a photo of the engine stamp! If it is 95+ the swap to my 1.6 DOHC will be more dificult?

If you have the DOHC this newer bp can be swapped fairly easily check out this link this is the only documented 95bp into DOHC b6 mx3 swap (IT is automatic so a little different plus he had a whole protege donor car) Definetly can be done http://www.mx-3.com/phpbb2/viewtopic.php?t=54032

I can't find anything on wikipedia!

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 VICS. This particular variant can be found in the following vehicles:

1989-1994 Mazda Familia GT (European & Australian Market)
1989-1994 Ford Laser TX3 (Australian Market)
1990-1994 Mazda Protege LX (with VICS)
1990-1994 Mazda Protege GT (Canadian Market)
1990-1993 Mazda 323 (European Market)
1992-1993 Ford Escort LX-E
1991-1996 Ford Escort GT
1991-1996 Mercury Tracer LTS
1994-1997 Kia Sephia GS
1994-1998 Mazda Familia (Japanese Market)
1994-1997 Mazda MX-5/Miata (this did not have VICS until 1999)


There is also a non-performance version that is most easily recognized by its black stamped-steel oil pan. It also features a cast crankshaft, no oil squirters, a plastic oil pickup tube and less aggressive camshafts. It is found in the 1995-1998 Mazda Protege ES.

B6D
1.6 L B6D - 1597 cc (78x83.6 mm) - The same strengthened and fuel-injected 16-valve DOHC B6 but with higher compression, no turbo, and the first Mazda engine to feature VICS (Variable Inertia Charge System). Most commonly found in the 1985-1988 Japanese market Familias, Etudes and Lasers, this engine was updated in 1989 with revised compression, heads and intake system (in a similar vein to the B5 DOHC) for the 1989-1991 Familia and Laser, then further refined for the 1991-1994 Mercury Capri and 1994-1996 2nd Generation Mazda MX-3 RS. The third generation B6D features a silver cam cover.
