Just wondering about this
B16A2 + CTR Cams + CTR Pistons = B16B?

or is there more to it?

thanks,
mike

 

There is more to it. The B16B is a taller block with longer rods. CTR pistons do not drop right into a B16A2 without some modifications.

thanks! appreciate the info!

 

b16a with ctr cams,ctr intake manifold,ctr throttle body, and if you fit the ctr pistons in it you have a poor mans ctr

 

not quite so, i have a b16A , and just put in CTR pistons. i mounted them on b16A rods though, but they worked perfectly.

 

sweet! so i can just order the pistons? and use the CTR pistons and wrist pins with my b16a rods? sweet..

i have heard this will up my compression.
is it a worthwhile hp mod for the $$??

thanks,
mike

 

Perhaps the B16A and B16A2 rods are different? I have not personally done this mod, but a friend of mine did it on his B16A2 (2000 Civic Si) and he had to have the rod machined slightly to get the CTR piston to fit.

I am going through the same with my b17a right now. (Has the same pr3 cylnd head and the(edit&gtB17a block is the same as b16a {except for crank and rods=1678cc's as uposed to the b16's 1595cc's}
Katman had a built b17a before. He mailed me a picture of the rod mod neccessary for adding ctr's .> http://tiiite.ghettoracer.com/Specs/B16+17rodmod_1.jpg
Hopefully that helps. But also... you forgot a few semi important factors . Ctr has a good rod ratio because of deck height, crank, rods , pistons w/ domes. Its basically a 1.8L block destroked to 1.6L for High reving. I guess honda did that because if they left it at 1.8L ..it would destroy a itr becuase of its lighter weight.
Yes it should up compression a bit! In my motor ...ctr's supposedly make ~ 11.5:1
Stock compression figures for the Type R motors are as follows: (usdm itr=10.6:1, Jdm itr =11:1 Ctr =10.8:1 ,

a lot of people on this board are quick to forget:

a b16b block is not a b16a block.

a b16b block is a b18c type R or gs-R block basically destroked to 1.6 liters.

To make a b16b u start with one of those two.and follow with the appropriate internals, crank, pistons, rods, etc etc.

edit: didnt read through clearly . spoon fanatic covered this

Also... I strongly suggest ...You don't waste any time trying to build a Ctr by destroking a b18c1... (if you had any weird notion of trying) it would be an absolute waste unless your sleeving to 84mm or building the head and motor to make power above 8500K!
Dude for the money, it is not that bad if you could sell your b16 block w/ internals and get a b18c1 block... You could press the pistons right onto the c1's rods and you will have good midrange displacement + more Compression!

 

well everyone basically answered your question...which is no, it's not a B16B but rather a poorman's B16B setup. Personally, I think its a better setup than a B16B engine. All you're missing out on is these few things:

- CTR crank -- which is counter-weight balanced and treated just like an ITR crank, no biggy though, B16A cranks are indestructable

- Rod ratio -- the rod ratio is a little better on a B16B **woopty doo*** though. B16A's have excellent rodratio to begin with.....so you're not losing out much in that department.

- Type-R head+Intake manifold -- this is the only thing you'd be missing out on that really counts, since it has tuned valvetrain, intake valves, and its ported, not to mention the R manifold which you can easily buy and use on any B16A/PR3 head.

You got it though, all you really need is B16B pistons, cams, and Intake manifold and you'll virtually have a B16B engine. If you come up on an ITR/CTR head...you're that much closer to mimicking the torqueless beast...


PS: don't forget to do the B16A rodmod before applying any 'R' piston or else an 'R' piston will NOT fit on a B16A rod.
