I just recently bought a 1986 rx7 13B with 175,000 miles, well the seals inside the engine are screwed and I am blowing grey smoke. It will last longer and cost less to drop in a 13B turbo, I need to know what parts are different and where I can buy the midsection pipe that fits between the front and main cat converters (because I found where to buy them) for the turbo exhaust or if you could suggest a better exhaust alternative that will pass emissions. I also need to know anything that’s different like hoses, brackets, ect.


Much appreciated,
Sean
