i have try'd searching the site for relative topics but was unsuccessful. I have several ca18 turbo motors siting in my shed all without wiring looms and turbos . I was wondering about the compatabilty of the 4 speed gear box bell housing bolt pattern is the same as a ca18 as is to the ca20. i conld go take some time and inspect the rear of the both motors but im sure there is somebody on here may have had experience with this type of conversion.

cheers for any input
