B20 Block, $100

#1 cylnder threw a main bearing(felt the bearing, its loose and wooply, rest are all snug), walls seem fine, 50,xxx on engine, missing water pump/flywheel

What should I look for before I buy this engine?
what do you all think?

going to run a b16head/b20block on my 00 civic si with this setup, built and tuned ~200whp

Is that rust? I dont know anything about buying an engine, but I wouldnt buy one with rust on the inside.

i have no idea what kinda engine that is, but if it spun a main bearing, probably the crank is shot.

you are going to have a complete machineing and blueprint of said engine i assume ?

just because the cylinder walls "seem fine", that doesn't tell you much, like how round they are, the actual dimension of the bore.

i would have your machinist/engine builder check it out before buying.

in this picture i see some obvious piston and deck damage i have highlighted.

im worried about the crank, I think im going to get it all worked on at a machine shop,


as for the area you highlighted I remember that, its a big carbon chunk on the piston, I flakes away, I dont think anything is wrong with that there

all depends what do you want to keep from that engine.but in total it is not good.

Normally you could have the block magnifluxed if it was an iron block...but since it's aluminum you can have it pressure checked for integrity. The crank can more than likely be turned .010 or .020 and polished and good as new. Machining the crank is usually cheaper, and they'll balance it for you. Check the main caps for scoring where the bearing failed. Seems like you said you were going to build it up which means all new internals so your main concern is the block. I highly doubt the seller will let you pressure check it because it won't come back in the same condition you picked it up. The rust is nothing, from the pics it doesnt' look like it's pitted rust so a .010 bore and hone will completely clean it up and ensure the cylinders are true.

I would agree with chevy, But if your going to build it up you should just replace the crank rather than machine the old one, but than again, it depends on what you consider (building up). The pics look good. Good luck!
