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. Labor typically about two grand because a number of things off the 2.0 need to be machined to fit the 2.5, including intake manifold.

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 Max Power 1.6 Inch Header, RoadsterSport 2.5 inch Midpipe and RoadsterSport 2.5 inch muffler (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, RoadsterSport Helmholtz 2.5 Midpipe, and SuperQ muffler, with 195 Ft/lbs of Torque! The stock exhaust can be used but results will be choked by at least 30 hp!

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. Sorry, we do NOT ship motors.

REVIEWS

Hey Brian, Recieved my Borla Dual Muffler Sport today from Fedex, and installed it in about 30-45 minutes. An Outstanding product with absolutely no drone throughout the power band, it sounds powerful, not at all like one of the ricey "fart tubes" that can be found elsewhere online. It has perfect like OEM fitment. Great prices, and great products. Product was shipped promptly and arrived as ordered. Would buy again!

Just wanted to thank you guys for the great stuff and great work done on my MX5 club yesterday. I could feel the difference in sound and performance right away! It drives and corners awesome now. Can't wait to tell my friends about you guys. I'll be keeping an eye on your web site for other goodies and events as well. Can't wait to try my new suspension out on a auto cross. Will definitely be trying it on some twisty roads this weekend. Just can't wipe that smile off my face when driving this car. Thanks again guys!
