Hey sorry to bump an old thread,
But what prep work should be done to a used oem 100mm crank before going into the build?
I thought I read somewhere turning them in a no-no. Maybe I'm wrong?

I put about 10K miles on my 2.3L build. It's a new 100mm MItsu crank. Lots of boost. It feels as it the motor is making more power smoothen out the last few thousand miles. I don't know what the WHP number is but Ted.B tuned it. It makes boosted/sprayed V8s play catch up a lot, too!

I've got a 2.4 oem crank that i can either:
(a): send out and have it balanced and turned, ($300?) or
(b): replace with a manley forged race series ($550)
Can anyone recommend a shop to work the crank?
Also, if I could definitively confirm the Manley crank is better than oem, I'd rather just order it and be done with it.
ugh.

You would THINK the manley would be better, but for $550, it makes you wonder

OEM here. Never had a question about the reliability of the stockers. Thought they were as bullet proof as it got.
Of course my car hasn't started yet so I can't personally quote reliability/longevity

I ended up with getting a Manley Forged.
I've heard horror stores of turned cranks spinning bearings. Unless I had a local machine shop i could trust, I just couldn't justify spending nearly as much as a new manley unit, especially since i'm looking more for longevity than shear strength.
Plus, fathouse said he traps 150mph on the manley forged so it'll certainly handle what i'm asking. (between 550 and 600 dynojet whp)
