Buildin myself an LSVtec got 2 cranks for the B18b block. Was told one was a GSR and the other an LS. How can I tell which one is which, are there any visual distinctions that I can find. Thanks in advance

 

ok here are your current issues.

First off the are the same piece. They have the same part # and im guessing they cost the same but knowing honda the gsr unit is probably more.
Second, you have 2 used cranks that you dont know the condition or what block they came from. I would highly recomend before droping it in with new bearings and bolting it down to take some very important measurements. If you dont have the capabilities to do this either have a shop, the dealer, or a machine shop mic out the crank to see which is within if not both are within tolerences. This can be done by yourself if you are compotnent reading a mic and dont mind takeing time with it. This is important because you could installed a bent crankshaft or have journals that need to be machined down to clean them up. Also, in doing this you would not be using standard bearings in order to make up for the machining work.

Again, verify either yourself or someone else that the parts are well within tolerances.

 

both are good i know that....the only thing is i bought a b18b block that was using a b18c crank in it...and then i got the b18b crank on side. now i just wanted to make sure that the guy didnt mistake having the b18c crank in the block for the b18b. i know they are good for two reason...when the block came out it was still running up until the day it was pulled... now along with that. i can make measurements and such no prob i have the time but still wanted to know if there were any numbers on the crank or visuals that would differentiate the two so i can make sure that one is the ls and one is the gsr. thanks

 

wrong...

LS has a longer stroke. LS crank's rod journals are also wider. Easiest way to tell would be measure the width of the rod journals on the crank.

Would you be interested in selling the crank that you don't use?

LS rods are weaker than Gsr rods....

 

babydaddy thanks for the input ill go measure them today i knew there would be something that would be an easy differentiation. and yes i am going to be selling the gsr one if you are interested. let me know. thanks again

 

thanks for the input, but can you verify this in anyway? From what i saw on acuracarland.com it appeared that they were looking and had the same number on both cranks. I have no problem at all standing corrected, just want to be sure that our buddy gets the correct info

 

 

trust me... i know...



but that is a shame that someone is listing it as the same part #. someone needs to tell them what's up!!!!

baby,
thanks for the feedback, i really appriciate the educated info. Again, i was just quoting someone. Nice machineing setup. IM glad to see someone can actually store a crank correctly. I have seen one too many laying on the ground or even stood up in a corner.

Again, thanks for the info.

 

it's all good

i can feel where your coming from. these boards are starting to become the mis-information superhighway.

just a side note:

that's not storing a crank in the first pic. it's hooked-up to a harmonic balancer. notice the tiny shaft on the left hand side? that's all hooked into that box on the top which does all the brain work. but i also feel ya on the cranks laying in the floor and stood-up in the corner.

i could tell you were about to spin it, wasn't sure if it was for testing purposes, balancing or what. I didnt see any cutting tools so i didnt think you were about to do any kind of machining.

 

We're talking about crankshafts, not connecting rods. And do you have any evidence whatsoever that "LS rods are weaker than Gsr rods....", or are we just supposed to trust someone who thinks that cranks and rods are the same thing?

This is Honda-Tech.com, not Honda-Misinformation.com

 

Just an FYI. Here are the part numbers for the crankshafts.

VTEC engine (GS-R): 13310-P72-000

non-VTEC engine (RS/LS/SE): 13310-PR4-A00
