b18c crank in b16a?????

[xixtony]

Hey sup guys ok this is my situation i have a jdm b16a but i blew but i messed up the head i wanted to rebuild this motor with some good internals. I was told that the gsr crank can handle a good power but i wasnt sure if i can put this crankshaft on the b16 since that crank is a b18. I also wanted to get some eagle rods or any good brand will do and some ctr pistons for high compression. A stock head , take out the dual springs and titanium retainers from the b16 head get a good set of valves (please tell me what brand of valves are good) and a set of skunk2 stage 2 cams If all this goes on with no problem tell me and if it dosent tell me if what can i do or what other part can i get to replace it need this car to run lol thanks i also want atlest 220hp or around there i wanna get the head port and polished but please help me out i wanna know if this setup will work or if i need any machine work thanks

its hard enough getting a b16 to 200whp and you want to go 220. idk it will be really hard. also the b16 crank is just as strong as the gsr crank, would you still want to use it. if you do i can calculate the length rod you would need

yea man thanks that would be great if u did that 4 me i sill just use the b16 crank get some good rods and the ctr pistons but if u can calculate that that would be great thanks

You won't make 220 WHP naturally aspirated in a street motor using a B16 crank, period. 200 WHP is damned lofty for a pump gas B16, nevermind 10% higher than that.

A GSR crank is an upgrade in a B16 because it has a longer stroke, which means more displacement. The B16 has a shorter deck height, so to use that crank in your B16 you need to run a set of custom rods or a set of custom pistons. Custom rods are a lot more money and time than custom pistons, so I would run a set of custom pistons. Since you more than likely have no clue what I'm talking about and have never done anything like this before I'd recommend a stock B16 with some stock rods and maybe some CTR pistons, a stock head with stock valves, some portflow springs/retainers, skunk2 pro1 cams, a skunk2 intake manifold, hondata, a good tune, and whatever exhaust setup you want.

ok this is for a gsr crank into a b16

b16 crank: 3.047/2= 1.523
b16 rods: 134/25.4= 5.276
aded together = 6.799
subtract gsr crank 3.433/2= 1.717
total new rod length = 5.082" rod
which gives you a r/s ratio of 1.48

If you're going to run a GSR or an LS crank in a B16 block, run GSR or LS rods and a custom piston. Custom pistons from CP are about 100 dollars more than a shelf stock piece, and take anywhere from 3 days to a week extra to make. Custom rods from Eagle are around 400 dollars, or double, the price of a shelf stock rod, and take anywhere from 4-6 weeks extra to make. For the price of his short rod, stock piston monstrosity he could almost have the LS/GSR crank with a set of eagle titanium rods and the custom pistons, it just doesn't make sense.

if they make a piston that can cover the shorter length needed then that would be good too

ok ummmmmmmmmmmmm it all comes down to what???? the gsr crank with b16 rods and ctr pistons??? "b16 crank: 3.047/2= 1.523
b16 rods: 134/25.4= 5.276
aded together = 6.799
subtract gsr crank 3.433/2= 1.717
total new rod length = 5.082" rod
which gives you a r/s ratio of 1.48"
Is this the rod legth with the gsr crank?? which setup would i see the most hp?? and which one would be the cheapest??

[xixtony]

***** ment to say b16 crank b16 rods and ctr pistons ???

[turboEKhatch]

You cannot run a GSR crank with B16 rods and CTR pistons. If you run B16 rods you need custom pistons.

The most power would be an LS crank. The least power would be a B16 crank. The easiest and only realistic option for you is the B16 crank.

[civickiller]

my numbers are for a gsr crank into a b16, but i agree with turboekhatch, that you should run the b16 crank and just keep it to internals, dont mess with custom rod lengths and stuff

[Kven]

to everything turboEKhatch said.

the b16 parts with the CTR pistons sounds good, go for it. Its much cheaper and easier than to stroke

btw; if you want to stroke, Omniman/Tech43 sells a piston kit for B16s that bring the displacment to about 1.9L(requires a 82mm bore though) by using a LS crankshaft, LS rods, and custom strutted pistons. You can search on Honda-tech for more info on it.

yea thats coo that what i was leaning towards to the b16 internals with the ctr pistons. about the ls crank wouldnt it hit the oil squirters on the bottom of the cylinder???

[civickiller]

i dont think it would

Never tried it in a B16 block, but it hits the oil squirters in GSR blocks so I have no reason to believe it wouldn't hit the squirters in a B16 block. Not a big deal, I ditched mine.
