Well, a couple things. I found out there are a couple different types of BPs.
Production 1998–2005
Engine 1.6-liter B6-ZE I4 (Europe/Japan)
1.8-liter BP-4W I4
1.8-liter BP-Z3 I4
1.8-liter turbocharged BPT I4 (Mazdaspeed)
BP-4W
The 1999 Miata uses a modified BP, the BP-4W, which replaces the old Hall Effect Cam Angle Sensor with a magnetic unit at the front and has an improved intake system. The United States 2004-2005 Mazdaspeed MX-5 turbo is based on this engine rather than the newer BP-Z3 and produces 178 hp (133 kW) and 166 ft·lbf (225 N·m) with slightly-reduced compression.
Applications:
1998-2000 Mazda MX-5/Miata
2004-2005 Mazdaspeed MX-5 (turbo)
BP-Z3
In 2001, Mazda introduced the BP-Z3 (also called BP-VE) variant of the BP engine with S-VT variable valve timing on the intake side, no more VICS, now replaced with the Variable Tumble Control System (VTCS), a similar torque enhancing set of partial butterflys that increases velocity. This was found in the 2001+ Miata. The Z family is an evolution of this engine.
In Australia, a turbocharged version of this engine produced 201 hp (150 kW) and 206 ft·lbf (280 N·m) in the Mazda MX-5 SP. The United States 2004-2005 Mazdaspeed MX-5 turbo is a BP-4W, not a BP-Z3.
Applications:
2001-2005 Mazda MX-5/Miata
Mazda MX-5 SP (Australian turbo)
Were you all aware of this, and hiding it from me? I found this out because I was trying to research the Turbo Kits for the Miata. They are for the BP. So why couldnt we buy these and install them into our Proteges/323s? Not enough room in the bay? I dont know, I havent found out yet. Any light on the subject greatly appreciated!
