Will it fit on the USDM KA24de? ('96) I've heard its 5 lbs lighter.

Um... aren't those Nissan parts? This is a Honda forum, try a different section, someone might know the answer there.

Nissan doesnt have its own JDM engine/parts forum. Im guessing this one serves for all the japanese manufacturers.

This is a Honda and Acura forum, hence the progression of links across the top and bottom of each page.
