how do i hook up water-meth injection on a 1982 sigma turbo

I am not familiar with this particular car, but if it's setup like most turbocharged cars, install the injector in the pipe that runs from the intercooler to the throttle body spraying in the direction of the intake manifold, which goes to the spark plugs and fuel injector area. Make sure the seal is air tight so you don't develop a boost leak. Other than that, you will love the effect of WI with methanol. It's so awesome on my Dodge SRT-4!
