ok please bear with me all i realy know is i love my 92 sc400!!! its not a stoplight sprinter but it is borderline erotic on the highway. i guess i am coming from the nemisiss 4 cilinder turbo class. my last faveret was a saab 900 turbo!!! sorry guys but she will allways hold a place in my hart! but now i have the best in reliability with a 8cilinder platform. my biggest obstical is money.i am disabled and raise 4 kids off a small pension. my question is what "all" is involved in turbocharging this car?and can you set up two small turbos one off each side? my car has 300+km will this motor take the upgrade with out a rebuild? i welcome all positive comments or critsisom thank you for your time
