AE86 Timing

Back in January I had my race at Motorsport Ranch Houston. The last race, I was in 2nd place, but coming out of diamonds edge, my car started to blog all of a sudden. Felt like it was low on power, and wouldn’t rev past 4k.

The car ran, but just terrible. I had to pit in and loose my spot for the race. The good thing, is the car ran, and no smoke or obvious serious issues.


After the race I get back to shop and started to figure out why it was running like crap. The motor was getting fuel, spark and air. But still ran like crap, I was thinking if the timing was off. Sure enough the timing was off! The timing marks didn’t line up. Thankfully the motor is non interference, and the internals was spared from damage


As I was resting the timing, I noticed a tear on the timing belt. Then I found out the culprit. A bolt for the rear timing cover came loose during the race, and cause the timing to slip! My adjustable cam gears also went out of timing.


To avoid future issues, I went to back to stock cam gears, replaced the timing belt, and added MRP N2 timing tensioner. This made the belt more secure to the constant redline.


To avoid this issue from happening again. I added loctite to the treads, and marked the bolts. This makes it easy for me to tell if the bolts are starting to get loose. Lessons learned in racing. But thankful it was worse. Thanks for reading!
