For those of you who converted already, what was the original car you got the engin from?




I heard that Mazda MX-5 used B8 until 2005 model. After 2006, it started using Z engines

http://en.wikipedia.org/wiki/Mazda_MX-5

I think 2005 MX-5 should have super low mileage and engines will still be new..

What do you guys think?
 
BP-4W

The 1999 Miata uses a modified BP, the BP-4W, which replaces the old http://wikicars.org/wiki/en/index.php?title=Hall_Effect&action=edit http://wikicars.org/wiki/en/index.php?title=Cam_Angle_Sensor&action=edit with a http://wikicars.org/wiki/en/index.php?title=Magnetic&action=edit unit at the front and has an improved http://wikicars.org/wiki/en/index.php?title=Intake_manifold&action=edit system. The United States 2004-2005 http://wikicars.org/wiki/en/index.php?title=Mazdaspeed_MX-5&action=edit 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 http://wikicars.org/wiki/en/index.php?title=Mazdaspeed_MX-5&action=edit (turbo)

BP-Z3

In 2001, Mazda introduced the BP-Z3 (also called BP-VE) variant of the BP engine with http://wikicars.org/wiki/en/index.php?title=S-VT&action=edit variable valve timing on the http://wikicars.org/wiki/en/index.php?title=Intake_manifold&action=edit side, no more http://wikicars.org/wiki/en/index.php?title=VICS&action=edit, 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 http://wikicars.org/wiki/en/index.php?title=Mazda_Z_engine&action=edit 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 http://wikicars.org/wiki/en/index.php?title=Mazdaspeed_MX-5&action=edit turbo is a BP-4W, not a BP-Z3.

Guys,

BP-4W and BP-Z3 are new improved and better evolution of old BPs..

Anyone converted to these?
