Im low on cash and im thinkin of gettin a ealry 90's 240sx but converting it to a silvia. There some things i need to know. First how much does the swap cost including engine wiring, ecu, and transmission. Second i live in Cali where smogging a car is difficult, how people smog there silvias here? Third is the swap reliable or will i break down everywhere. Fourth Do i need to get bigger brakes or fuel management or anything to make the car run the best? Fifth Will the engine be certified if i get it from a respectable place. And thats about it. I keep on askin the people in the silvia room but know one answers the questions. I dont know if there isnt that many people in that forum or what. But in this forum they always get answered.
