    Hi,

    I currently have a b16a and am trying to build it up for NA power. I have been offered a b16b shortblock, would it be possible to run my b16a head on this block, using b16b cams? Or is it going to be easier to add the cams, and put b16b pistons into my b16a?

    Also, what is the easiest way to run Hondata s200 on a PW0 ECU?

    thanks

    Dave

    No point switching blocks, B16A/B Blocks are the exact same. If you want the added comp. swap out the pistons, cams, and valvetrain off the B16B and throw 'em on your B16A. While you've got the head off, giving it a light PnP could be an idea as well. After all thats said and done, you've got yourself a B16B.

    i thought the block heights were different, so the 2 engines had different rod lengths?

    Cus isnt the b16b essentially a de-tuned b18c5, they run the same block, because you can put the b18 crank and rods in the b16b.

    no, it is essentially a tuned b16, higher domed pistons = higher compression with dual valvesprings with more agressive cams, with a better intake manifold, with a better stock header

    for the price of a b16b, you could build a motor that would put out better numbers but if your just looking to get reliable power out of the box you could get a b18c5/R motor for a little more than that of a b16b with more stock power.

    the b16b is a nice motor if you want to say that hey i have a civic type R b16b motor in my car. Other than that there are better swaps for the same money

    No, they are not. The B18C ITR and the B16B blocks are the same. The CTR is a destroked ITR block.

    If you install the B16A head on the B16B block, you'll be a porting and valve job away from a CTR.


    *this is why the B16B stroker kits tell you that it can not be used in a B16A.

    My bad. No wonder that engine sold so terribly....why not just buy an ITR?

    But nevertheless, I figure a straight up B16A with CTR pistons, cams, and valvetrain will put down about the same power as a B16B, for cheaper. De-tuned ITR block or not, it would be the same displacement, same compression ratio, and same cam profile. Just port the IM, throw on a JDM ITR 4-1 header, and chip your ecu to handle a 8600-8700RPM redline, and you should be there.

    I dunno, just my 0.02

    Just get the b16b block, and put your b16 head on it you, will be happy with it. Plus down the line you can put a gsr/type r/LS crank and rods in it and have a 1.8.

    Yip, and probably be cheaper too. But if the B16B block is cheap enough, hell why not.

    Dammit John, I was SO about to come unglued on this mofo....


    Bah!



    But yeah. A B16B is pretty much a destroked B18CR. The blocks are exactly the same.

    Us three, actually. That's one of the rarely discussed tidbits of information I've completely memorized. :p

    actually the compression ratio would be 11.4:1 because ctr pistons on b16a rods in a b16a block come slightly out of the hole while ctr pistons in a b16b block are like .050" into the hole.

    Interesting. That's actually a little tidbit that gets discussed around me quite a bit. Oh well.

    haha I've seen it discussed on this board 3 times in the past two years. But hell if I was around you more I'd discuss damn near anything so I could soak up some information.
