All that's needed is a new crank signal plate, that's it. It's a drop in replacement.

Crankshaft: 12201-JA03A
Crank Signal Plate: 12314-6N20A
Bolts for Crank Signal Plate: 12315-EN200
Will the signal plate that is on the 02-05 crank bolt on to the 07+ crank? If not, where do I find a plate to bolt onto the 07+?

hopefully this will clear things up....

The wheel on the left is a first generation crank signal wheel, the wheel on the right is a second generation wheel and is made to work with the NEW ECUs. The wheel you want is a combination of the Gen I TOOTH pattern with a Gen II bolt pattern and center hole.

I have pics of the CORRECT wheel somewhere in my photo bucket but I have to head out to work so I can;t look for it.

The correct part number has been listed in this thread and it is also listed in Nissan Sport Magazine.

Nice my man, cant get any clearer than that. Would be nice tho if you could track down that pic...O and you wouldn't by chance know what ft/lb the bolts that hold on that plate are supposed to be torqued at, do ya?

Ok, I got another question...the two keys (I guess thats what you call them) that are on the snout of the old crank, can they be removed and installed on the new crank? My new crank did not come with any. :thinking:

12201-ET80A is the crank for 6MT.

you're correct in saying the 12201-JA03A is for AUTOMATIC trans and is not the fully counterweighted version

So I should order the 6mt crank correct? Or is the auto crank is forged and not the 6mt cranks in the 07 specv? Thanks In advance

get new ones.

1. they're cheap ( don't be a cheapass here )
2. they're a pain in the ass to remove from the old crank, you'll probably scratch it all up as well


might have to heat up the end of the crank slightly to make them easier to install, they're kind of tight.
