ive hear the b16b is just a destroked b18c5 and all you need to do is replace it with a b18 crank..which b18 crank do I need??c1?c5??thanks alot

 

either one or an ls crank as long as you use coresponding rods.
b16b rods will be too long

 

nope. they are two separate things.

look at this site: http://www.c-speedracing.com

go to the how to, then the compression calculator...you'll see even with a stock headgasket that the cr comes quite high. not bad high, but you'll need custom rods to run the c5 crank. otherwise you'll have some clearance issues.

 

an ls crank and gsr\iTR is different...

the b16b is a destroked b18c motor... replace the cank and rods with b18c's and you'll have a 1.8 with the 1.6 stamp

 

ok this is new to me.

so let me ask u guys a few questions.

so b16a, ctr pistons, ctr cams, new valvetrain. (what i plan to get)

then i would buy a b18c crank, and b18c rods? and i will now have a 1.8L?

what about compression? timing? do i need a new ecu?

i am very interested. will all this work?

gus, you are a n00b... displacement is related to bore, but not directly.

stroking is another way to get displacement. Heard of a stroker kit? Basically you gain displacement with a crank that has a larger distance frlom the center to where the rods mount. I'll explain all of this to you in person, much easier.

peace,
ryan

no they are talking about a b16b. you have a b16a. they have diffrent deck heights.

would it make a difference in my set up? maybe not 1.8L but still would i get some more displacment?

and would all that work together?

 

your pistons would hit your head. you can use a b17 craink and rods to make it a 1.7ltr though.

ls crank is different but you can use it in a b16b as long as you use ls rods.

I hope you do a better job explaining it in person than here. Bore size not directly related to displacement??? HAHAHA! Who is the n00b now?

Displacement = Bore^2/4 * Stroke * Pi * Number of Cylinders you have

This is in mm^3. Divide by 1000 to get cc's.

This is math, not voodoo magic.

 

Search.... this topic is covered like 3 times a week.

B16b= same deck height as b18a/b/c. Which means technically you can use a B18C crank/rods to make a 1.8 or a b18a/b crank/rods to make a 1.8.

B16a= 7mm (I believe)shorter deck height than others. Same as B17 which means you can use a b17 crank and rods in a B16a.

Bore is related to displacement, so is stroke.

Heres a little pic I threw together for one of the threads I posted on a while back since both blocks were outta my car.

Just crank and rods? Everything else left alone?

.... sounds like a good compromise to me, shouldn't even be too expensive, hmmmm....
