does anyone know of a turbo kit for a 93 escort gt? would the cosworth versions turbo bolt up to mine?

The cossie wont even come close, but thats ok because it would cost a lot to get a turbo and mani from a cossie.
You motor is made by Mazda, so none of the ford based motor parts are compatible with your 1.8 GT.
Your motor is a good motor for boost, and there are turbo parts avalible.
