Hello Hondatech this is the first thread I've ever started and I just want help
with one question. I'm currently building up cash to buy a B18C1 to work on
before I get back to school where I'll hopefully have a 96-00 civic ex coupe (ek
chassis i believe?) shell by then where I can drop it in. I wanna bore the block
out to 84 mm but I wanna get aftermarket sleeves to handle more horsepower
(I wanna go all out full rebuild with turbo 400+hp.) So here's the question, do I
have to buy the sleeves beforehand and bore them out while in the block or do
I get it bored bigger then put the sleeves in? I don't know if Im making any
sense but any answers to this question would be greatly appreciated since its
been picking at my mind for a while now.Thanks =]

just send the bare block to golden eagle, rs machine.....
they'll do all the work there.
is gonna cost you $900-$1200

Or Laskey Racing, just got my block back from them. Equally as awesome!

send the block out to where ruben19 said and have them bore it as well, or have a shop do when its assembled. or are you going to assemble it to yourself?

well i want it to be a learning experience as well so i wanna do as much work on my
own as i can. I just wanted to know how the cylinder sleeves worked because i never knew
exactly how that would work out i got the engine/car completely figured out to what i wanna do and what i want it to be. Its been my dream to get this car for a couple of years now and im finally getting close to getting it =]

well this is something you can't to by yourself. only machine shops have the proper equipment to get it done.

For the sake of learning, I'll answer the question. They install the sleeves and then bore them out because that insures the cylinder walls are all perfectly lined up with each other, then they surface the block to ensure flatness. If they bored them to the right size first, then they could end up slightly tilted.
When you send your block off to be sleeved, they normally ask for you to send in your pistons also so they can get the correct piston to wall clearances.

Not sure if it's required in your case since I'm not an expert on forced induction, but talk to your engine builder about o-ringing the block. Even if you don't need it, it's an interesting practice and it's relatively cheap insurance. Basicly they machine a small groove into the top of the sleeves where they meet the head and put copper wire in the groove. This makes a better seal and helps prevent head gasket failure.

If your goal is only 400 hp you do that on stock sleeves.

You say your going back to school.

Before you spend the money, that you may need for school, think about what your doing. Do you have the tools required ?

Are you going to school full time without a job ?

Think about all the stuff that has to happen, make a list, put prices next to the items.

If you want to do this, like they have said above, send the block, pistons and may be the crank I say crank because I don't know if your crank is from the same block, to either Rob Adkins Robert@goldeneaglemfg.com tell him I sent you or Mike Laskey at www.laskeyracing.com both are some of the best.

May be talk with them first before you spend your money.

All I'm saying is, make sure you have the money to do this before you get in over your head. Your young, you have time, school is more important.

yes you don't need aftermarket sleeves for that much power.. just go with lower cr pistons, some turbo tuff rods, and a fresh set of oem or acl bearings you're pretty much set..

For your power goals, the stock sleeves will work just fine...dont get ahead of yourself. As for the rest of the engine, you can go with a simple piston/rod setup. I'm in the same ballpark for power and went with 9.8:1 Arias pistons and Eagle rods on a stock bore 81mm LS. Sleeving adds a bit of security to the whole build, but it isn't necessary
