240SX LS swap
A typical 240SX LS swap runs about $12,000–$18,000 in parts ($8,268 on a budget), and the big decision is where the engine sits: S13 and S14 use different holes in the ISR bracket, and CX's kit is automatic-only.

Oil pan
3 options · $654.99–$783.96Why you need it: The pan has to clear the crossmember, the ground and, on a 4x4, the front differential. S13/S14 swaps use a front-sump pan; the aluminum swap pans hang low and crack on a hard hit. More: oil pan guide.

Steering
1 option so far · $145.99Why you need it: The engine and headers have to clear the steering shaft and box, and some swaps need a new shaft or box to make room. Kit headers clear the left-hand-drive shaft, and a line kit mates the LS pump to the Nissan rack. More: steering shaft and box clearance.

Most run a T56, Magnum or TR6060; a CD009 takes an adapter plate, and the stock bellhousing has to be cut off. More: transmission guide.

Cooling
2 options · $345–$486.20Why you need it: LS water pumps put both hoses on the passenger side and the engine needs a steam line, so the radiator needs LS-style ports or an adapter.
