question:

if i put a ls crankshaft in a b18c5 block will it stroke it any ???

 

in short terms...minorly.... yes...

stroke of b18c1 and b18c5- 87.2mm
compared to
stroke of b18b crank- 89.0mm
difference 1.7mm...lower r/s ratio of

but...
Rule!!!! Any B series rod will fit any B series crank, EXCEPT the B18C's and B16B (CTR) ( etc.... "R" family: ITR, GSR, CTR).
so have fun trying to machine th c5 rods to that crank....

also learn this formula- Block Deck Height = (Stroke/2) + Rod Length + Compression Height + Stock Deck Clearance

 

yes it'll be like a ls/vtec but better.
89mm stroke.

 

ok then another question who has done this and do they think the benifited from it?
and what was involved?

 

Don't bother. Stick with the ITR crank.

 

Basically it would be an LS/VTEC with oil squirters and the oil passages in the correct locations. You may have to bend the oil squirters since the crank has a longer stroke and may tap them a bit.

 

back up because search ****ING SUCKS and i cant find enough info on this.


so.... i would need to use aftermarket or LS rods on this setup?
and is it even worth the extra torque?
