LS vs 2JZ: which swap is better?

A proposed comparison from published figures:

	LS (LS1/LS3)	Toyota 2JZ
Layout	90° V8, cam-in-block	Inline-6, DOHC
Height	28 in	28.5 in
Length / width	29.5 in long, 24 in wide	Speedway lists 26 in long and 30.7 in wide (unusual for an inline-six; verify for your application)
Weight	415–460 lb (aluminum LS)	Not in our sources yet
Cost	Plentiful, affordable; 475 hp 5.3 crate ≈$5k+	Speedway: "highly sought after… can be quite expensive"
Strengths	Compact, light, cheap, huge aftermarket; bolt-in kits for most popular chassis	Iron block and forged internals (2JZ-GTE) take big boost; 1,000+ hp builds are common
Swap work	Bolt-in mounts, pans and headers exist for most swaps	Often custom mounts; transmission choices like the Nissan CD009 or GM T56/Tremec Magnum; standalone ECU common

Bottom line (Speedway): the LS is the easy, affordable, well-supported swap. The 2JZ is the "legend" choice for high-boost builds, but costs more to buy and usually needs more custom fabrication. The 2JZ is typically chosen for its character and its reputation for handling big boost.
