Super eta crank.

[slammed_e30]

My question is can a healthy super eta block handle the I head, Manly the crank?

[Bill 84 318i]

Yeah, it'll be fine.

TD crank

[peerless]

Kinda curious about this myself. The 85' 325e used a cast crank, the 318 had a forged steel crank. Is there a M20 Forged steel crank lurking in a different model?

But then again if your where going that far, do the M50 swap. Although I don't have specs
on that crank but I assume its forged.

Anyone got specifics on this :?:

the eta crank is fine up to around 6500 rpm's.... you're fine

The eta and super eta crank are the same cast cranks
The i crank is also cast...
I use a eta crank in my stroker with Nitrous and i have had no problems reving it up to 7000 rpm....

Just loving it.....

thank you for the info!

You can get away with the eta crank, but if you can scrounge the $$ then try to go with the forged TD.
