I just purchased a 2000 jdm B18c motor. Currently is has high compression which will be fun for a while until I can afford a turbo, etc. My question is what type of pistons should I get in order to lower my compression, as well as, what other components do i need to make this motor handle the turbo very well.

 

i am sorry i am no help but where did you get your motor from...was it purchased online??? i am just wondering becuase i am looking for a b18c1 motor...thanks..

 

I had the hardest time trying to find it, but I have a reputable contact if your interested PM me. I finally got it after 5 months of looking.

 

pm'ed you ;]

 

If you're going to be swapping the pistons out, you might as well go with some forged ones to lower the C/R. While you're at it, you might as well get some forged rods as well. JE, Wiseco, and Arias all make very nice forged pistons in a range of C/R's. Crower, Manley, and Pauter all make very strong rods, although they are a bit pricey. A cost-effective rod that is still many times stronger than stock would be the Eagle rods. They are also available with an ARP custom age rod bolt upgrade which ups the size of the rod bolts for extra strength.. In stock form, the Eagles come with ARP2000 bolts, which are fine for milder setups. Depend on how hard you'll be running the setup, you may want to get the block resleeved while you have it torn down. I would say anything over about 14-15lbs of boost, you should probably look into some new sleeves.

 

Thanks man. Thats eaxactly what I was looking for. I was looking to resleeve it as well:thumbup:

 

When you decide to build up your block for that turbo consider the cost and then look at importbuilders.com and look at their prices. My friend just got his 2.0L GSR engine back from them and had them dyno it too. The guy that invented Hondata tuned their car. 222whp! Those guys know how to build `em.

If you decide to do it don't forget to balance and blueprint that bottom end. Don't waste your time on knife edging the crank. Its not worth it. I would suggest sleeves definitely. How much would it suck to have the pistons and rods that can handle the boost, but then your sleeves can't. Since you'll have sleeves you might as well bore the engine out too. Get as much displacement as you can.

 

This is prob a dumb question, but if I do bore my engine for more displacement will that degrade the stregth of the block?

 

yes. to a point. if you take away metal from a block it will always degrade the stregth

 

No it won't degrade the strength of the block.

Here's how boring out works. You have your piston sleeves that the pistons slide through. When you bore out the sleeves are bored out to a larger diameter. If you keep stock sleeves then you shouldn't overbore more than .5mm (or .020"). However since you'll be putting in (for example) GE or Darton ductile iron sleeves then you can go from the stock bore of 81mm to 85mm! If you do that to a B16 you'll effectively change your engine from a 1.6L to a 1.8L!

So...boring out your future iron sleeves won't degrade the integrity of the block. Since they're iron sleeves they're SUPER strong. So boring them out won't weaken them.

BTW, I believe Darton and Eagle sell sleeves that come prebored out to 84mm (the stock B20 block bore). So then you can over bore those sleeves to 85mm (that's .040" over). This overboring principle/info will work with any B series engine.

Hope this helps.
