1. Always keep up with routine maintenance schedules as outlined in the owner’s manual.

2. Upgrade chassis and engine grounding points.

 3. Replace cooling system plastic air separator (A.S.T.), well known for splitting in half with no warning causing massive coolant loss and overheating.

4. Replace that dirty fuel filter!!!  Countless premature engine failures are caused by a dirty fuel filters. Don’t let this happen to you.  Poor fuel quality also contributes to engine failures ALWAYS USE PREMIUM FUEL!!!

5. Install a turbo boost gauge!  This is the only way to be sure the turbos are working properly.  All are easy to install, and come pre‑wired with detailed instructions. 

6.Use fuel lubricant.  This has been proven to extend engine life at least 30%.  

7. Get a Fire Extinguisher!!  A must have for any vehicle...that way you will never need it!

8. Most RX7’s benefit from cooler operating temperatures. Replace the stock 210f fan temp switch with a 185f switch. As the Rx7 gets older its common to see 225f before the fans kick on. As we all know cooler running improves longevity for the engine as well as all under hood components.

9. Whenever possible open the oven door (hood) this stops the baking process and improves longevity for all under hood components. We have many customers that have proven this works; their cars continue to perform flawlessly year after year. 

10. Take your time and always install upgrades in logical stages and only one at a time, this allows you to evaluate changes in vehicle dynamics made by each modification, and if any problems arise, you only have to go back one step to find the cause.
