I have four motors for sale. These were all installed in my racecar and have varying levels of mileage on them:
1. PWC spec 2.5L – 0.020” overbore, 12:1 compression. Long block. Makes massive torque. Faster than an E46 S54 is NASA ST4 spec. Break-in on dyno + 1 race. Not used since NASA Champs in 2018.
2. Stock 2.5L – purchased as a crate motor from Mazda. Short block. Ran only 2 seasons (15 race weekends). Won NASA Champs PTD in 2015 & and PTC in 2016
3. Stock 2.0L – purchased as a crate more from Mazda. Short block. Ran only ½ season before switching to the 2.5L. 2nd in NASA Champs PTD 2014
4. MX-5 Cup sealed 2.0L – Came with the car when purchased in 2012. Short block. Won NASA Champs PTD 2012; 2nd in 2013. Blown head gasket in mid-2014 from a cracked coolant reservoir.
I also have a set of 2.5L 12:1 compression ratio pistons. They are designed for the standard 2.5L bore. Let me know if you need any other race parts or spares. There's a good chance that I have them...
