ok so i have a few questions, to start off i have a swap in mind that i'm sure no one has done yet. i currently own a 1981 toyota celica gt, a small 4 cyl liftback that i have plans of building into a diesel. now i do know that a om60x series mbz diesel will with and be legal here in the people's republic of california. my main question is could i shoe-horn a 4bd1t into my little car and keep it legal? ill call the BAR office and see if it is even possible. i do know the engine is heavy due to the fact it was for the npr trucks, im also sure it wont be cheap to find or make fit. i just want to see where everything falls before i start. thanks for all the help.
