what can i look for under the hood of an 86 5kt to ensure the motor is of the MC variety (code, numbers, etc)? is there a major difference between the MCs in 86 and 88? Does anyone want to give me a 20v turbo motor?? Also... what's the deal with turbocharging a 20v 91CQ? Different motor all together, or can a turbo from one of those good ones be adapted? tanks, dave
