As I said before, I recommend that you replace your crank bearings. Depending on how many miles you have on your car and how hard those miles were, it may be a good idea to replace the rod bearings as well. It's pretty easy, but rather than taking instructions from a forum, you should use a service manual to walk you through. On some cars, the instructions come with the purchase of the rebuild kit (which includes gaskets, bearings, seals & rings IIRC).

I'm not an expert on rings, but since you're not honing the cylinders I would think you would want to replace them with stock rings.

 

Once you obtain the parts, I think I'd have a shop do the rebuild for you. I don't know what type of specialized tools might be needed but I'm sure there are at least a couple. By the time you figure out what is actually needed and the price of these tools, the cost of having someone r/r the engine might be the most econimical and almost definitly much less time consuming. If you count your time as money, why bother?

 

where do i get e rebuild kit from? doin all this in my garage with some help from people.

 

I don't know of a kit. When I did something like this, I just bought the parts from Honda. The bearing shells have to be matched to the block and the crank. You should have marked the shells when you disassembled the block so, they can go back to exactly the same spot they were before.

You MUST have a shop manual or you will F up this build. The shop manual shows you how to match bearings to the marks on the block and crank.

I don't see any specialized tools other than maybe a ring compressor. On a Type-R motor, the rod bolts have to be tightened with a bolt stretch gauge but, the F20 motor doesn't use that technique.

Read the manual. It will tell you everything you need to know. If you don't follow directions, you won't have good results.

Keep everything covered, all the time. I kept my engine in a bag other than when I was working on it. I'd so something, then rebag it when I was done. It's like doing surgery on a human, the cleaner you keep it, the better the results.

 

I have no idea if anyone has a rebuild kit for the AP1 engine. I would expect that you could buy kits for Civic & Accord engines. Major auto part chains should carry rebuild kits for many common engines, but I wouldn't bet money that a kit would exist for the AP1 engine.

EK9 makes some good points. Get a shop manual. After you have read what it takes, you can decide if you really want to do it yourself.

 

Any of u guys know how much it would cost to hot tank the block?

 

Are you in contact with a machine shop? They're the ones to ask. Make sure it's the right kind of tank. Last I'd heard some hot tanks can chemically melt the block.
