Looking for the easiest most cost effective way of: A/ Fitting the pre '90 DE(T) intake plenum onto the post '90 DE(TT)? B/ Fitting the required idle control. Being either pre '90 stepper or post '90 solenoid? I have both engines. However the DE(T) requires crank bearings and I am not 100% sure whether it was turbo or not at this stage. I was intending on fabricating CNC adapter plates either way: My main concern is that if I opt to use the pre '90 DE(T) lower intake manifold there will be added expense of converting the fuel injectors otherwise I would have to run the ancient and perhaps impractical quad rail injectors with resistors. :vomit::vomit::vomit: Regards
