Hey all, I've just acquired a B18A motor/trans/ecu/etc., which I plan on building up and boosting in my crx that is currently D16Z6 powered. Where should I start on this block/head? I've done lots of motor swaps and external mods, but this will be my first true block buildup. I plan on having it bored to 2.0L, but is there anything that I need to treat with special care or keep in certain orders when I start tearing everything down?

Thanks in advance!

 

you should diffinetly start with the head, and work you way down to the block.lol.. it aint going to be cheap tho....Good Luck

 

if you want an over bore i would just sleeve it.

 

yeah, i know it's not going to be cheap, but I'm going to just do it real slow and take my time. I just want to make sure I do it right. How much of an overbore is a 2.0L? I didn't think it would be that much that it would need new sleeves.

 

over boring a cylinder makes the walls thinner which makes them weaker. Sleeving it using better materials will hold up to boost better.

I wouldnt bore it at all if u plan on turboing it. just up the psi by 2 to compensate

 

I would highly recommend getting a Helms manual. You can either buy the actual book ( http://www.helminc.com ) or sometimes you can find them in pdf format. I see you have a b18a. I have that manual in pdf. IM me if you want, I dont want to post a link to it in a public forum.

I believe in order to make a b18a/b/c into a 2.0 liter, it needs to be bored to about 84mm. You'd need to sleeve it to go that big.

 

good info! Thanks! What about the actual disassembly, anything to look for there?

 

There's a few things that need to have the bolts taken off in a sequence in order to prevent warpage (like the cylinder head, flywheel, etc). You'll find that info in the helms I gave you the link to.
