Finally Found a motor!

After many weeks of looking for a replacement motor with many deals not working out i was searching for a b18b (1.8 liter) but then found the b18c for a super deal and bought that, its basically 10x cooler. it is a VTEC motor and is rated 170 hp and 130 ft/lbs here is an explanation of how VTEC works it's pretty cool it's a way to put two cams in one motor.  It came out of a GS-R Integra.
The plan is to send it off to the machine shop and have all the machine work done and all parts in the block and head will be replaced.


This is the motor after it was brought home. it took two hispanic's to lift it in and some how took 3 1/2 white boys to get it out. and my dad kept saying to whole time "this is a bad idea" well it went perfectly except he thought we needed 8 hands to do it so he throught out his back.

Some new Mods

So I was at the junkyard getting some misc. hardware and saw some fat 'ol rotors and calipers and decided to swap em in for mine. and i polished the calipers and am planning on brushing or sand blasting the suspension parts and repainting them, as they are super ugly. the calipers have bigger pots and the rotors are about a inch bigger in diameter and are slotted. I have comparison pictures, but not right now.

Plans for the car

The motor has been out a while and this gives me many opportunities to improve things and clean up. I did some extensive cleaning and gutting of the bay to find some surface rust i need to take car of. So there are a few things left but the whole bay is going to get a coat of paint. Another thing popular to modding these cars is custom wiring, mostly just to hide it and make working on the motor easier. I'm still debating it but i might re-wire the whole bay and motor,
here is a more recent picture of the cars state...

Engine Tear Down

The motor that came in the car must have had a really horrible previous owner that didn't know what oil is. Because the car spun a rod bearing, when a rod bearing fails it means that oil couldn't get to it and the rod starts to wear directly on the crankshaft and the causes tremendous friction and the bearing eventually seizes to crank and spin around ruining that crank. So I dismantled the motor and found which one it was by doing a simple test where you tap the rods with a hammer and the sound is distinct when the bearings are bad. and i inspected my oil and found some of the material the bearings are made out of, they are usually about 4-5 layers of different alloys for different purposes. I didn't filter my oil but i kind of want to now. There would be more pieces in there.




This is a piece of the bearing, i put the motor back together because it was taking up lots of room in pieces and then after i finished i realized i forgot to take pictures. 

      Some causes of a spun bearing are usually not changing the oil, a bad oil pump, or improper assembly, i don't know what it was, but it wasn't oil changes.
