Hey, my name is Chris, and I'm pretty new to the RX world. I've always been interested in them but rotary motors absolutely fascinate me now, and I had the chance to get one a few months back.
I was wondering if a N/A 88 rx7 could hold any boost stock. Someone told me that its a must to rebuild it before boosting it unless I want my car to be down after 2 weeks, due to weak factory apex seals. Just wondering if someone knew anything deeper on that subject.
The only thing done to my car is bolt on exhaust from the middle back. What are some of the first things I can do to make my car more solid?
Also, I've seen ppl do something with their headlights in videos. They somehow rig up their lights where they stay on while down. I know if your headlights are down and you pull the high beam lever the lights come on, but are there any ways to make the headlights stay down and completely come on like normal?
