350Z LS swap
A typical 350Z LS swap runs about $15,000–$20,000 in parts ($12,000 on a budget), and the big decision is where the engine sits: the engine crossmember has to come down from the rails to get the pan past the steering rack.

4 options · $80–$1,724.97Why you need it: An LS needs its own bellhousing or adapter and the right flexplate or flywheel, and an electronic transmission needs a computer to shift it.
