Hey H-T,

I'm looking to get some clarification on two cranks I have. I have been looking for the past few days on how to identify the cranks, but I have come up with nothing. If you guys could point me in the right direction or if you happen to know what these cranks are that would be great.

Here are the pictures of the cranks:

Crank #1









Crank #2









I appreciate the help!

Thanks
Billy

Any input??

you need to measure the stroke, the distance the rod part moves vertically. 89mm is ls/b20. 87.2mm is gsr, and there's a b20 prelude with a 92mm stroke, and there's something shorter for the b16. The width of the rod journal differs between a couple cranks but that basically differentiates vtec and non-vtec I believe.

Honda Crankshaft Identification

The AERA Technical Committee offers the following information on crankshaft identification for Honda four cylinder engines. Generally, there are no reliable casting numbers on Honda crankshaft and physical identification is required if the engine family is not known. In some instances, there may be a difference in crankshafts for the same engine family. Refer to the chart below to assist in
crankshaft identification, all dimensions are given in inches.

Total Length Flange Bolts
Nose Dia. Counterweights
