Hi I have a blacktop sr20det engine and i need a crankshaft for it. I went to junkyard and found a sr20 engine. I bought the crankshaft. And the part number is on the crankhaft is 60j45, I know sr20 uses 60j00 and 60j10. Is anyone know that is this cranksaft usable or not?
I have never heard 60j45.
I have made a research about this cranksahft but found nothing.
Any ideas?

60j45 is a fwd sr20de crankshaft of some sort. Fwd and rwd cranks are the same. I'm pretty sure the number itself is in reference to the oem bearing clearances.

It's best to use OEM bearings as they have more sizes to better suit your desired tolerances. Have the machine shop measure what size bearings you need and go from there.

You should be able to go to nissan with the part number from the crank and get whatever bearing sizes came on it originally.

Thanks a lot guys for your help. Tomorrow i will go to Nissan and ask for the bearings .
Now i have two options
1) micro polishing the 60j00 crankshaft and using acl 0.05 or 0.025 bearings
2) using 60j45 crankshaft ( never polished and original specs.) with oem bearings
Which option is the best and durable for track days?
Are the bearings for "60j45(fwd sr20de)" and "60j00/10 (rwd sr20det)" has the same strenght or not?
Sorry about my bad English

Today i went to Nissan to ask bearings for 60j45 and he couldnt find anything about it. He told me that "i need chasis number of the car which uses 60j45 then i will found bearings for it". I am so confused.

Mics are the best way to do this although you can fetch similar results per fsm... You need to look for the numbers of journal and rod grades stamped on your crankshaft, and correlate them to the numbers stamped on your block. (numbers on block are for mains only, use rod numbers off crank. Rod races are identical for all 4,) This cross-reference/ decoding procedure is covered in the FSM. Following this method will result tight oem clearance. Go a grade or two lower if you want some added clearance.
