Performance Parts Zone

For those that don’t know me, I love the rotary motor, ive owned 2, a Mazda RX7 and a Mazda RX8.  There is just something about them that makes you fall in love with it as soon as you get behind the wheel.  With my RX8, there was never a dull moment in the car, every second behind the wheel was fun.  These cars handle unbelievably well, and while a little underpowered, they still feel quick. 

Todays Ride of the Day owner, Justin Terramagra, took care of the underpowered aspect of the car with a host of performance parts, including the Greddy Turbo Kit.  In addition to the Turbo kit, a Greddy Type RS BOV, Mazdaspeed Exhaust, Greddy Oil Pan and Catch tank were added to round things out.  An Interceptor EMS and Greddy Profec E01 was employed to fine tune everything and get the most out of the turbo setup. 

The outside of the car remains mostly stock to suprise unsuspecting kids that think they are fast.  The addition of clear side markers and some window tint give the car subtle touches that take an already great looking car and make it that much better.

While we dont have a definitive plan for the RX8 just yet, we went ahead and ordered some of the parts we know we will need during this build. Today we focused on ordering parts to help keep the car running cool no matter the circumstances or performance modifications, i.e. Turbo or Nitrous.  

Its common knowledge that the Rotary motors found in the Mazda RX line of cars, run hotter than most any car on the market.  To keep heat from becoming a factor while tuning we ordered some necessary updgrades to the cooling system today. 

  We started by ordering a Koyo Radiator to keep the coolant temps down.  Not only is the Koyo Radiator built to OE specs, but the all aluminum radiator should be easy to install and reduce engine temps by 20 ro 30 percent.   Next we ordered a set of Agency Power Silicone Radiatior Hoses, not that they reduce heat, but they do increase coolant flow and we dont have to worry about busting a radiatior hose during tuning if we boost the 13B.  To top off the cooling parts list, we ordered the Greddy Air Diffuser Panel and Greddy Oil Pan.  The Air Diffuser Panel should help the cooling process by diverting air directly across the radiator core.  The Greddy Oil Pan not only increases cooling by holding another qt of oil, but its aluminum construction has cooling fins built around the entire oil pan.  Any air coming across the bottom of the car should keep the oil cool.

  I think with the above modifications, we will not run hot not matter what we decide to do to the Mazda.  Hopefully ill have all these parts in stock and on the car with in the next week or two and ill update you then. Im going to avg the cars running temp now for the next two weeks and then avg it again after the parts are installed.  I may even do a before and after run on the dyno to see if the decreased temperatures had any effect on performance at all.
