so i bought a 1983 280zx turbo for 200$ and it sat for 14 years before i got it. ive replaced the fuel pump, injectors, most vacuum lines, spark plugs and wires, distributor cap and rotor, brake master cylinder, slave cylinder, clutch master cylinder and it runs and drives okish. between 2800-3200 rpm it has a real rough spot where it struggles to contine reving. my dad says its just the turbo having bad bearings or at least clogged ones because we took it out and it spun freely and felt like a almost 40 year old turbo. the car also has a issue with starting because it floods itself. could this be because the car isint sucking as much air as it should be and the computer is sending the correct amount of fuel as if the turbo was spinning as fast as it should be and drawing the correct amount of air? i have no idea and if i cant fix these problems im gonna have to let the car go and i really dont want to do that so any suggestions on how to fix it or whats wrong that i dont know about?
