If it doesn't come with the car (GNX) how is it worth more money then a GN drive train? Because the turbo has a "ceramic" wheel? Who cares, it's old technology! I apologize if I sound condescending but one must be realistic. I have my stock motor and my stock tranny (BRF) I'll take 4k for them any day! ANY DAY..... I'll even hand deliver them. I just took them out and they're both sitting in a trailer. Probably have to pay someone to take the tranny and the motor I'm going to rebuild it because it's worth nothing as it sits right now. But if someone out there wants to give me 4k for them I'll be more then happy to take your money. God knows I need it... I'm so poor I can't pay attention.... Used to be able to get a brand new short block thru GM for $1,500.
