Thank you. You have rated this product.

BRAND NEW 2.5 Mazda Factory Motor for TORQUE like you have never felt in your MX5 Miata before! Same motor used in our Project Blue 2006, see our forum for lots of additional pictures and materials. You bring us your 2006-2014 MX5 and legendary Miata Guru Rocky "Miatomotive" will use the crank pulley and oil pan from your old 2.0 to fit a brand new 2.5 motor into your MX5, including porting the intake manifold from your 2.0 to mate neatly with the NEW Mazda L5Y0 2.5 motor (note that if your old motor had rod failure then likely need new oil pan).

This price does not include the labor for install and you need our $799 ECU reflash package also available on this site.

Other options to consider are our upgraded engine mounts, headers, radiator, and clutch (all are easier to do if done at the same time as the motor transplant). Or, skip all the extras except the reflash and for about the same money as forced induction kits you get your extra power and torque INSTALLED! And you get it without a big jump in extra weight on the front of the car, extra belts and complications, just pure smooth BIGGER factory motor torque everywhere from start to redline!

Low line is original best stock run on this car (lucky to hit 140 range on this dyno AT THE WHEELS), middle line is with RoadsterSport header, midpipe and RSII exhaust (upper 160s range)....and high pair of overlapping lines are with 2.5 conversion with 200 HP at the WHEELS using our NEW MAX POWER 1.8 inch primary header, Helmholtz Midpipe and SuperQ muffler, with 195 Ft/lbs of Torque!

BRIAN's APPLICATION NOTES: If you have a car with blown motor towed to us for this conversion, please make sure trans is NOT in gear during the tow or you may be needing a trans too! INSTALLED HERE BY ROCKY MIATAMOTIVE, the installation side of the shop, under the same roof.

Good morning Brian, I finally got a chance to put the exhaust on, great advice, it's just loud enough, solid product. I'm running without the baffles, sounds great in power band. Take care, you have all my future upgrade business.........regards.
