b18c5 built , need some advive

So i got this b18c5 that i bought from the fastest allmotor front wheel drive b-series here on my country(11sec/allmotor crx). They sold everything cause of a dropped valve so i bought it for a very good price
This engine was allready 1mm bore but where the valve dropped it damaged a little bit so a had to rebored it again , right now the block is 82.5mm bore. I want to know if that is safe? The block also have block guard and it is full arp with eagle rods. I ordered usdm itr spec piston but 82.5 , i got skunk pro series intake , headers, cai, tunable ecu(eCtune)
my head is stock , what do you guys think? is the block safe?

Safe for what goal? Why did you ask after you already ordered the pistons? I would go ahead and just get it sleeved then you can get whatever bore you want

I have read some where that the eagle rod wont fit on the itr piston? What is exaclty the problem or the difference can some one explain me and tell me exaclty what do i have to do for the fitting. When i bought the engine it had cp forged piston with a compr of 12 something , i still got the pins wouldn they fit?

When you go to have the rotating assembly balanced, you'll just have to grind some of rod at the wrist pin, instead of the side of the rod like normal. It's not a deal breaker, just a pain like @JDR said.

In a bit more detail. The Eagle rod is just a tiny bit to big for the wrist to move inside of the piston head properly. There are a few ways of fixing this issue. But this is the most common. Re-bore the piston head and rod wrist pin hole to match and either have the piston head or rod re-machined to make the fit better. Again, this can be done during the balancing phase.

BTW max safe bore on stock sleeves is 87mm, you have a long way to go before you have to worry about the piston punching through the sleeves.

BTW, do always confirm the sizes of all your parts before doing the mods to the piston and/or rod. Some piston manufactures take into account that most people will want to run Eagle rods or something and take care of the resizing while the part is being made.

82mm is about the max you would want to go on a stock sleeve B18c to be safe. There would be nothing safe about 87mm on stock sleeves.
