OEM VS. Aftermarket Bearings

DSMDUDE-The factory 4g63 CAST crank can be reground just fine. Re-nitriting is recommended, and the cast should work just fine. I have had personal experience with a few renitrated cranks that have been undercut and they work just fine.
Is a factory crank that isn't undercut nice? Yes, is it required, not always when on a budget.

how much does the regrind cost with the nitrate? a good used crank is like 50 bucks wouldn't this be cheaper than the undercut?

i could see doing it possibly with the 2.4l as it is getting harder to find the 2.4 blocks and cranks.

i would do it more for piece of mind. even if it did cost a little more at least that is 1 less thing the machine shop has the possibility of screwing up. curious- how much does the grind job usually go for?

[niterydr]

Typically grinding runs about $90 bucks, I think the nitrating is $100-200ish (I am thinking $100, but it could be more, not sure)...so you are looking at roughly $200 into the crank. Sometimes its cost effective, sometimes not, just depends upon the availability of cranks. Compared to a good used crank, not cost effective, compared to a new crank from mitsubishi at list price? yes its cheaper.

Me thinks the Swanster should check again, as the 4G63 cranks are forged, not cast. Almost all import cranks are forged, most american cranks are cast though.

Uhh..Jet, I am not sure what you put in your motor, maybe an Eagle forged crank or something, but I am pretty damm sure they are cast. Actually I KNOW they are cast. They are a good casting, but they are cast. Go look at the casting marks on a crank and tell me that is from forging. The 1993+ 3000gt vr4 cranks are forged. I don't remember about other cars from the top of my head.
I dunno, I've only delt with about a hundred 4g63/4g64 cranks, maybe I've just missed all the forged ones. :)
Just giving ya shit buddy, everyone makes mistakes.
Back to on topic:
Did you ever figure out your bearing situation Mike?

I thought the 4g63 cranks were cast, and I have looked all over the net, Only to find ither they are cast or forged. There are a number of people saying both for the 4g63/4g64, ither forged or cast. I hit a cast crank(spare 3/s crank we know is cast, and a spare DSM crank) lightly with a hammer and they sound almost the same. Then we tried Ryans forged 3/s crank and that was a higher pitch ring. Also the casting or parting line in the crank is another way to tell. A cast crank has a thin or "sharp" ridge to it and a forged crank has a flat and wide parting line. So ither way the DSM crank is good for all the power the block can handle, if its forged or not.
