In 2011, I had Louis build this motor from a Mazda crate motor that had 1 season on it.  A year later debris got inside the motor and destroyed 2 pistons.  He rebuilt both the head and bottom end, doing a 10-overbore (15 lb penalty in SM, but more HP/Torque).   The motor was built as a 100% SCCA and NASA legal engine.  Fully legal.

I ran the motor in the car for 3 years and finished strong at all events, including the SCCA Runoffs in Monterey (18th of 45, and 3rd fastest 1.6 powered SM) and won SoCal NASA Regional SM Championship in 2013 using this motor.

Before the last race I had Louis dyno the motor on his chassis dyno.  Made 125 HP and 112 ft lbs torque, which is was 1 and 1 less than it had when it was new, meaning this is a very strong and competitive motor.  

Well maintained.   The oil changed every other race weekend.  Schaeffer synthetic.  Water changed 1 time per year, as well as fuel filter.

Includes balanced ACT clutch and complete motor as you see in the photos.  Injectors rebuilt a couple years ago.  New coil and cam sensor a couple years ago. 

I removed the motor from the car (also for sale), and am selling the motor separately.  Spent about well over 15K on this motor over the years and it is as strong as it was when it was new.  Asking $3K. 

Call Dave at 619-944-2002 if you have any questions.

Local pickup preferred, but I can send by truck just about anywhere in the USA.  I suspect the cost is near $400, including a $100 crate fee.
