I recently bought a 1992 ls400 and am wanting to do some engine modifications. Cams, injectors, piston heads, etc. If anyone could point me in the direction of some websites that would be great

 

Cliff notes: parts are few and far between, the 1uz (while growing in popularity) isn't an especially common platform for modification. Hard parts (forged internals) are available, as are camshafts and injectors, but not exactly in a bolt-on affair at all.

long version: http://lmgtfy.com/?q=ls400+performance+modifications and search the forum. Lextreme is a good place to look for resources but you're asking far too general a question.

 

Ive noticed haha. Thank you for your help
