EVIL GENIUS RACING's standard labor charge for rebuilding a Mazda (Miata or non-turbo RX7) 5-speed is $350.00. Parts are additional. EGR charges $390 for Miata and RX8 6 speeds and $460 for Turbo RX7s. EGR also rebuilds almost all types of manual transmissions and transaxles, Porsche, T5, T56, BMW, ZF, Getrag, Toyota, Honda and others. We even built a transaxle for a '65 Corvair that survived the 2008 Carrera Panamerica!

An average (somewhat worn) Spec Miata transmission will require 3rd and 4th gear syncro rings, a 3/4 shift fork, a tailshaft bushing and all the seals and gaskets. These parts run about $150.00. A more seriously abused transmission will also need 1st and 2nd syncros, 1/2 shift fork and some or all of the bearings. Mazda RX-7 transmissions are more variable, but will always need a tailshaft bushing, some syncros and a bearing or two. EGR stocks most of the parts needed for Mazda transmissions. Customers can also supply their own parts. For example, if you're a racer registered with Mazda Comp, EGR can e-mail you a parts list after teardown of your transmission and you can order the parts using your account and have them shipped directly to EGR - just tell them to send the parts to "John at EGR"... they have our address! This can save you quite a bit of dough. EGR also has a decent stock of used parts to help you save $.

EGR can also put Miata gears into an RX-7 case, affording a closer ratio transmission without spending a ton of money. This requires a donor Miata trans and some minor machining. The price for this service is $375.00 plus $100 for machine work.

Need a higher 5th gear for your Miata? Tired of buzzing the engine on the freeway? EGR can install a taller 5th gear. Call or e-mail for details. Typical turnaround time for most transmission work is 3 business days.
