Will this work? Will a b18c rods be able to bolt to a b16a crank? It's just that I already have the b16a, and I can pick up the b18c block for cheap. I'm aiming for a heavily N/A, so I figured a b16b would be the way to go, but I want to do it without shelling out 4k for the swap.

 

you would need the ctr crank and ctr rods...

cause if you do the b16a crank with integra b18c rods in the b18c block it wont be right...

also whats so bad about the b18c block with stock internals that you want to do this?

 

Im thinking about it ,,could you use a standard B16a crank with B16b rods in the B18c motor? or is the B16a and B16b cranks different in size?

Yes, this will work but why?

CTR rods are hard to come by.

Why not B18C components?

If you want high torque numbers and high hp numbers, I would just get an ITR crank and ITR connecting rods for the B18C. Makes more sense then staying 1.6L, and ITR cranks are pretty common to come buy, and are not too pricy (for what they are) from Honda.

 

I'm putting it into an 88 hf, and I figured a car that light won't exactly need the extra torque, but rather, like a bike, would use high revs to make power. I figured the r/s ratio of the b16b was my best friend in this situation. Just a theory I had... Anyways I plan on building the entire head, bottom end... to make power up high. The reason I posted this is becuase I heard that b18c rods would not bolt into the b16a crank, becuase they were too narrow, but I have no way of finding out if that's true or not.

bump

 

Maybe think about investing in a stroker kit??

 

you CANT run B18C rods on a B16A crank...they are different withs

B16A and B16B cranks are DIFFERENT...i KNOW this for a 100% fact... https://honda-tech.com/zerothread?id=1469575 <~proof.. i have had them side by side...

CTR rods are LONGER than any other B-series rods...they dont interchange with anything...

B16B = SUPER HIGH REVS and yes its true no torque

B18/20 = torque... high revs = broken parts and fucked bearings

true like i said. and as for everyone elses opinions (B18/20), fuckem i like your theory personally. with a light car a B16B would be a awsome choice. with a light *** car you wont be needing all that torque and the topend revs and hp would really help out your car....just dont be a ***** an not rev it!

if your planning on building the motor there are also a couple other things to consider:
pistons will have to be CUSTOM...the CTR piston is taller, any shelf piston will give you LOWER compression
rods will have to be custom made also...same reason as above, they are longer.


&lt;~B16B crank and rods sitting under bed waiting for the want to build an NA motor lol

 

isnt there a thread that talks about the b17a crank in the b18c block, its pretty much a b16b

 

That would make it a 1.7L. Not a 1.6. The only way you can make a B16B, is with CTR cams, CTR pistons and a 1.6L crank, and any B block. But you would need the CTR head (or ITR, same head) as it flows better then older gens, (B16a-2-3/B18C1) I beleive.

 

you cant use "any" B-series block, it would have to be a P72 block (B18C1, B18C5/6, B18C, B16B) you cant use a B16A block because it has a shorter deck hieght...

ITR and CTR heads are different....but pretty close...both PR3 heads with factory porting, same sized valves, and same springs im pretty sure...but the CTR uses a diff valve grind, there are several posts on this if you search...

 

wow, I read your thread, and I'm trying the same build. Very informative. Where did you find a b16b crank??? I've looked all over for one, but can't seem to find one.

 

ebay....

you might be able to talk me out of mine...
