Question about 1987 Mazda RX-7
Hey i have a 87 rx 7 and it runs great untill you hit 4000 rpm then it starts to cut out. any idea?
Sounds like plugged up pre cats, my NA had the same problem I got a Racing Beat header that eliminated the pre cats and it went away. I've also seen them on eBay for cheaper. Either way you can't lose the stock header is like a cast iron stove attached to the engine it's heavy and massive.
