Miata Turbo Forum - Boost cars, acquire cats.

Hello from Washington. So I bought a 90 miata from a guy who had swapped in a 93 engine and advanced the timing. Since buying it I have put on a cold air intake and a suspension consisting of tokico struts and springs. I am planning on buying a tsudo exhaust within a month, and then when the car maintenance is done I will be moving on to the really fun part of the turbo. My buddy put on the Begi S kit and I am in love with the car, but don't want to spend quite that much money unless I have to. I am thinking about the Begi Shanghai kit, and installing it myself will definitely help keep costs down. I am open to any suggestions though.
