My funds will dry up towards the end of this summer, so i'm trying to complete my engine by than. If not the (below mentioned route) i will save up over the course of the next few monthes and go with aftermarket rods/pistons.

For what seems like forever now, I have my skunk2 stage 2 cams, springs, retainers, PE belt, ITR manifold, and every single gasket and seal that can be replaced on the head...just sitting there.
In a few weeks I'm going to rip off the head and have a 3 angle valve job & a port & polish done.

But now my concerns are with compression. The motor is a B16A2, (10.2.1 ) and will have to run on 91 octane. So i thought something a higher, but not too high would do nicely for me.
If the head is off, should I consider throwing in some B16B pistons ? With a spoon gasket that would yield an 11.1 compression ratio, which would be just fine.

Without going overbore, just the stock size replacement, if i have some people that know how to do a re-install, do i HAVE to hone the block? And can this be done with the block still in the car? And what needs to be balanced ? In every search i've found, you have to hone the block, but I've talked to so many people that just drop the new pistons right in.

 

I`d go ahead and bump teh compression up. It`s cheap power.

I agree.

 

Its best to hone the cylinders because you will be installing new pistons, which means new rings. For the rings to seat properly, you should hone the block.

 

alright, i just wanted to verify it's needed.

So can this be done with head taken off, and the block in the car ?
thanks guys

 

Since you are taking the block out to get honed, you might as well go with Civic Type R oversized pistons. They are .25 overbored.

 

with the spoon gasket it will be closer to 11.5:1 but thats evenbetter.

 

dont spend money on a spoon gasket when uc an get a cometic for 80$...high comp
