I’m looking for a crankshaft for a B18C/C6. Journals have to be good with no scoring etc, if a crank pulley is also available then that would be good as I’ll be needing one of those too.
Would also possibly take a complete bottom end if the price is right
Thanks!
 
Would it have to be a C/C6 crank or C4 possible too? I don't have 1 I'm afraid, just out of interest :) I know C6 cranks can go for a fair bit more than C4 since they differ. You building up your bottom end :nice:
 
I’ve been told there is a slight difference between C6 and C4, so would rather a C6 one if possible!
Aye the bottom end is away to be built, got a call off my engine builder telling me the crank wasn’t spinning as freely as it should, also has uneven wear on the timing belt side mean bearing, it’s sftually worn unevenly across that one bearing which points to a very slight bend at the nose of the crank
I could get the balance of it checked but I feel it would be a waste of money after seeing the issues the engine has. Strange cause it drove totally fine with no noises

Yh the c6 is slightly different with larger or heavier counterweights I believe, couple of forum threads out there on it. I'm guessing he's measured up the journals. Oooh slight bend! Hmm interesting, yh is bit strange and unfortunate. Wonder what would've caused that.
 
Pm’d you Irf
Yeah that’s what I’d heard too Pete, a C4 one would do the job, but I was told C6 ones cope with higher revs better, don’t know how much truth is in that though!
Yeah it’s very strange, my builder has seen it happen once before on a B18. Hard to say what’s caused it, he’s said the engine just seems to have had its day, I wonder if there’s been a bit of imbalance in th crank pulley though, just cause the issue is right at the end of the crank, is perfect across the rest of the length of it!
 
Hi, I have a JDM B18C DC2 Type R Spec 96 (with 34K only) crankpulley complete with the bolts and D-belt hardware (tensioner and spring are sold):
