sure they are low mile engine out of JAPAN. ( read there how we test it page first)
just be sure of warranty.
and how much it costs to send engine back, if no good. (some hide price ,say free ship)
that is bunk ,it aint free. but effectively hides the return price ( tricky dogs huh?)
keep eyes wide open.
lets say you check compression sitting on a pallet. ( i'd do that for sure)
and it had a dead cyl. ( one person reported that here)
I use a spare bell housing off s 5speed to mount the starter to a pelleted engine.
bingo , full Compr.test. with out and then with. 1 teaspoon of oil in cyl.
I also check oil pressure , sparks out, spinning engine at full starter speed.
cheers.
id find a local wrecking yard, that has a good warranty.

or get a rebuilt short block ,or rebuild yours. (many cross country , google them)
then do a valve job (not expensive when you consider total costs)
ask the local machine shop how much to rebuild your , dropped off block.
worse case (assuming no freeze damage) you might need another used crank or one that was rebuilt.
the JDM can be be the fastest fix, if it's any good, if not?, its longer. and more expensive , with shipping.
just a crap shoot. as anything used is.
cheers.
there are always 3 choices. rebuild yours, used, new.
it think suz still sells short blocks.
finding good used parts is more art than science. (adding tests, helps)
