I just disassembled the rest of my B16B CTR block last night to notice the rods were all stamped "P72" on them. Are they the same rods found in the ITR B18C5. I am wondering if its just the crankshaft and pistons that only make up the difference between the CTR and ITR blocks?

 

I think the block height is different too

 

deck height for the B16B is the same as the ITR/GSR block.

I believe the pistons don't make up the deck difference, I thought they used a unique rod that was longer than normal GSR/ITR rods to make up the difference in stroke.

B16B is something of a mystery still, in terms of rod length. Everyone says something different.

 

You could measure them and compare, since you have them in your hand anyway. I have a type r rod to measure too, if the lenghts aren't easy to find.

 

I think i'll have to measure them, but i can tell you that because of the P72 stamping, it makes me think they are the same.

the fact that they are stamped P72 would lead me to believe that as well. However, a ITR rod with the B16 crankshaft wouldn't be long enough to reach the top of the deck, even with massive pistons like CTR's.

No, the B18C1, B18C5, B16B, and B18C all used the exact same block!

 

If you have p72 rods, its probably a 1.8 crank. Spoon sells a 1.8 strokers kit for b16b which is just itr crank,rods, and pistons. As mentions aboved b16b is just a 1.8 block destroked to a 1.6.

 

that would be most unfortunate, since you probably didn't buy a b16B for its displacement, but for its unique traits and rarity.

I hope this is not the case. The stoke of the crank SHOULD be 77mm.

Let us know.

 

B16B pistons infact ARE longer than B18C/C1/C5 rods. They're actually the longest B-series rod.

Sounds like your B16B was stroked to 1.8L.

He meant B16b Rods

 

so you are saying that if i had a b16b blcok and put itr rods, gsr crankshaft, and itr pistons, i would have an itr motor?

sounds like a lame *** question, but if its true, why not just do that to all of the b16b motors to make them 1.8 liters?

 

because that defeats the purpose of the b16b: rev really high without exploding onto the street

very correct.

Stroking B16B's is a rather popular thing to do in japan.

They always try to sell me stupid b16b crankshafts

 

Its funny, it never occured to me that the bottom end may have been stroked out. I guess the only other thing to do is identify the crankshaft. Its there some type of marking on it that makes it easy to distingwish between B18C5 and B16B?

 

I measured the type r rod today, 7" end to end, 5" from center to center of each hole.

mmm, how did you measure that?
they sound very off.that would mean they are shorter than a b16 rod...

 

JDM Super Tape Measure Type R. And maybe they should be shorter, as the stroke increased from 77.4 to 87.2 while the block height increases from 263 to 270. I don't know if the wrist pin is in a different place though.

hehe, tape measure is no good.wrist pin is same size on all b's (21mm)
b16 rod lenght= 134mm
b18c= 137.9
why are you comparing b16 and b18 blocks. dont you have a b18 height block with a 77mm crank?

 

I don't have a B16B crank image handy, but here's how you can compare ITR & GSR cranks, which you can reference against your CTR crank (if you have one)...

i just opened up MY b16b and found P72 rods also!!!

anyone actually have a picture of a B16B rod?

how about a crank?

 

b16b rods are longer than b18c5's. A b16b uses a b16 crank, therefore needs a longer rod. Ending up with a 1.74 rod/stroke ratio. When I removed my rods they were also stamped with p72, along with many other parts on my motor.

 

so, are we saying that:

1. B16B rods have "P72" stamped on them?

2. they are not the same P72 rods found in a G18C1

3. is there some unique stamp to differentiate these from a 18C1 rod?

trying to do this without opening up my engine.


DOES ANYONE HAVE DETAILED PICTURES OF THESE RODS????!!!???
