Good-Win Racing 2.5 Conversion!

DESCRIPTION

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 2006-2015 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). Note we do NOT ship motors!

This price does not include the labor for install and you need ECU reflash package also available from Mike XERO Limit. 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 (roughly 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! 95 octane! The stock exhaust can be used but results will be choked by at least 30 hp!

BRIAN's APPLICATION NOTES: Note our recommended 1.8 inch primary header shown attached to the motor in these pictures is SO BIG that you cannot lower the motor with drop mounts or lowering mounts because this header is already using ALL AVAILABLE SPACE. We do suggest our RoadsterSport MX-5 Competition Motor Mounts with any 2.5 conversion.
