I will be putting my car away for a while and tearing the motor out and rebuilding it. Motor is a B18B1, bone stock from what I can tell. The motor was previously boosted, and each cylinder is currently at about 140psi.

I will be putting new rings in it, and I was planning on getting a hone, but then my friend said to bore it out. I have no idea how many miles are on the motor, but it has definitely seen better days. It leaks quite a bit of oil, but doesn't burn any from what I can tell.

I am a college student on a budget, so I am trying to avoid getting new internals, which is why I am avoiding getting the cylinders bored. Any input is appreciated.

 

take it to a machine shop and have them check the block.

A min. I would hone it. you may need to bore/hone it. we can't tell you that.

 

What all would I need to get parts wise if I did have to bore it?

And should I be worried about any of the bearings on the crankshaft? The motor sounds pretty solid from what I can tell.

 

You would need new pistons.


Worried as far as what?

I would probualy replace them while I was in there. but i'm really **** when it comes to stuff like this.

 

I'd definitely replace the bearings if you're gonna rebuild it. OEM.

 

Your friend who said to bore it out knows about as much regarding your motor as we do: nothing. Take the motor to a machine shop, and have them tell you if it needs to be bored, or just honed. As long as it's not warped, you should be able to get away with a good hone job.

If you're ripping apart the bottom end, it's always a good idea to go ahead and replace your rings, bearings, and seals while you're down there. Might as well get it done now while the engine is out, instead of having to pull the motor again when an old wear item finally gives out later. It all comes down to this: spend a little more money now, or a lot more money later.

 

boring depends on how out of round your cylinders are. or tapered.

 

rebuild after the machine shop tells you if the block is fine to reuse.
Budget yes... but its your transportation.
