Identifying main journal bearings - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I'm having a problem finding out the numbers for my main journal bearings. I can't seem the find the numbers stamped on the block anywhere. Does anyone know where exactly it is stamped on the block? The other set of numbers that I have are stamped on the crank. The top numbers say 12123 and the bottom numbers say 1111. What do the bottom numbers represent? After I find all the numbers, how do I calculate what color bearings I need? I just want to buy the original bearings that were on before cuz the motor has low mileage and I'm just refreshing the motor. Will the s14 sr20 fsm have the same method as mine? That's all I have right now.

Btw, I have a s13 blacktop sr20det motor.

Thanks

Due to the number of questions we got on this - I went ahead and put together something on our site to help. Check it out here -

S13 Redtop/Blacktop and S14 Blacktop are identical calculations and location.

That's awesome thanks! I found the numbers on my block. So here are the numbers on the block: 22212, and the numbers on the crank are 12123. So the numbers for the bearings will be 34335. Does this mean the original bearing colors were yellow, blue, yellow, yellow, pink? Just need a confirmation.

Thanks for your help.
