Hey guys,

I've been looking to buying a 2001 frontier for cheap. I also have the bottom block of a 1991 240sx KA24DE just laying around.

The motor on the frontier is basically gone so I've been researching and trying to find more info on the differences in the blocks.

This what I found:

Differences in the Japanese block to Mexican are also present. The Mexico blocks (all DEs except those found in the S series) implemented a distributor and oil pump drive more similar to the L series; from the crank nose. They also used a single row chain for the upper timing assembly with no valve cover mounted guide. In addition to this, they removed the rearmost cam journal in the Mexico head. The crank rides on individually capped bearings with a slightly smaller diameter than the Japanese block, with shorter, slightly lower compression pistons in cylinders who have thicker walls than the Japanese DE. They retained the knock sensor and piston oilers.

I wanted to know if anyone had actually used the 240 engine in the frontier or had any experience or know how if anyone actually did it. I know there are some differences but am I able to use the bottom block (just the bottom) and transfer everything else from the frontier engine to the bottom block of the 240 bottom block.

IIRC, the Mexican DE blocks are essentially the same bottom end as a KA24E, but with the DE head. Can't confirm this though.
