its seems to be a trend lately to do this but balance that thing so you can rev high like a gsr

Ls crank in the GSR block would give you some good potential. Just make sure you get the oil squirters out of the way.

P.S. caps lock, turn it off.

I'm currently trying to do that setup in my b18c1 too. And the on 2nd and 4th cylinder the piston, and the crank counter weights sandwiches the oil squirts. Can anyone tell me how to bend this correctly, or how to prevent it from getting slap around? Expert advice???

AHHHH!!! what are you peeps thinking? just because you blance your rotating mass doesnt mean you can buzz the motor to the moon. you have to consier rod stroke, AND the fact that the stock rod bolts suck *** on ls motors (even if you replace them with arp's it doesnt make it that much stronger). ok... rod stroke broken down

b18b
137mm rod
89mm stroke
8mm rod bolt

137/89 =1.5393 r/s ratio

stock rev limit = 6900rpm

b18c
138mm rod
87.5mm stroke
9mm rod bolt

138/87.5 = 1.5771 r/s ratio

stock rev limit = 8200 rpm

b16
134.4mm rod
77.4mm crank
8mm rod bolt? (not sure)

1.7364 r/s ratio

stock rev = 8200 rpm

now... your probably wondering, if the b16 has such a badass r/s why cant you rev forever? well, you can (hehe, almost), but the problem is, the stock cylinder head cannot flow enough air.

anyways, i just thought i'd let you know some of that info. but if you have some theory on why the ls crank is so great (other that that measly few ft lbs) please explain it to me.

Yes. Lift up the crankshaft, and strategically place it on top of the the selected block.

bend them however you can, just dont break them, it'll work.

i rev my ITR with an Ls crank to 8700 when i race. and thats just because i want it to last. it makes power farther than that. we pull to 9+ on the dyno and its fine. bearings are great.leakdown #s are great, cylinder walls looked good as of 4000miles on the motor. if you build it correctly, you can get the benefit of the "measly few ft lbs" without the cons you are referring to.

as for the oil squirters, just make sure you have enough clearance between them and the crank. bend them enough out of the cranks way. and then either bend them again, or cut the skirt of the piston to clear the piston.

i dont calculate rev limits, there are too many factors

the rev limits i stated b4 are factory honda rev limits

i never said you can't rev to 9k or even 10k for that matter. its a matter of reliability. my friend revved his built ls-v to 9.5 all day. how long did it last? less than 4 months. this was with crower rods.

Are you the kind of person who reads some **** on the internet and thinks he knows it all? There are more benefits than just "a few measly lb. ft.". I'd explain it to you, but I'm lazy.

to answer your question. yes you can. and if you have the ls crank, then do it! i've heard that the oil squirters get in the way so i would do some research on that. but i wouldnt want to put those ls pistons in, they will lower you compression ratio. I'm sure you could find a deal on some OEM pistons

What happened to it, why did it only last 4 months, I'm curious. If you could be a little more specific...

quick question:
I had allways thought that the B18A/B block was 1mm taller than the B18C, so when you put the B18A/B crank in rods in the B18C the piston stuck out 1mm more?
Am i wrong? is the B18B and the B18C block identical (except for oil squirters/girdle/oil cooler/etc.)? so in theory can I put GSR crank and rods in a LS and have it work the same?

b20, b18a/b/c and b16b blocks are from what i know are the same height the b16a and b17a blocks are the short ones

what happens to all of those who overrev b18a/b?

rod through the block

im not sure if the deck heights are the same, but either way it will work. here is why:

gsr stroke = 87.5mm
gsr rod = 138mm
(87.5+138)

ls stroke = 89mm
ls rod = 137mm
(89+137=226)

now the only other factor i can think of that will affect you piston to deck clearance is piston height (that is measured from the center of the wrist pin to the top of the piston [no, the top of the piston is not the top of the dome]) Now dont quote me, but i think it would be safe to assume that they would have identical piston heights, but someone please correct me if i am wrong.

look man, this sight is about spreading knowledge, not bashing. now if your going to call me out and say that i'm misinformed, please back yourself up. if you arent going to do that, than please dont say anything at all. it's people like you that have ruined what HT used to be.

No they don't. Specific information is readily available here on Honda-Tech.

The rod/stroke ratio isn't really a good indicator of how high a motor can rev. A smaller rod/stroke ratio means more lateral stress on the cylinder walls which causes weaker engines to lose stability and do nasty, evil things. Lack of balance also causes instability which leads to similar nasty, evil things. By correctly balancing/blueprinting the rotating assembly and replacing the stock sleeves with stronger, more stable ones, you'll have problems in the head well before the bottom end has reached it's limits.
