I have a 94 Civic with a block outta a 2000 its a D16Y8 and I was going to bore it 30 over but I cannot find the pistons anywhere. Can someone help me?

 

you can't find them because no one does that size. normal is .5mm or what would be a little smaller than 20 over.

 

where would be a good place to go and find the pistons and rings at when I decide how far to bore it?

 

All depend in what you want to build. i.e. stock or F.I. But you can start with this: (note the first one says specify the bore size at order).

wait, why do you have to bore it 30 over anyways

 

like kyden said, there's no 30 pistons off the shelf. He's need to go with 70mm or 75.5mm, if not is sleeved where other options are available.

 

I know I could not get away with just hone the block its way to far gone. I am eventually goin to boost the motor and sense I am going through the whole motor anyways while I am looking for the new head I wanna go ahead and bore the block I should be able to get away with 70mm. Just want to get all the machine work done at one time crank balanced and everything u know.

 

Then your going to need some custom pistions made

 

There's a reason you can't bore .030 over. There's not enough material between the cylinder walls. Check out your cylinders if they are not egged out there's not point in boring. But on high mileage cars it's common for the #1 cylinder to get egg shaped from oiling. At least 3 of them I've dealt with have. It's then you need to bore and only then... But if you need to go more than .020 time for a new block.

If you can get away with just honing the cylinder,,, That's exactly what I'd do... :cool: You aren't getting didly squat increase in displacement with a .020 increase in bore....
