PLEASE dont turn the crank, honda cranks are soo unreliable once you turn them. just find another one forl ike 20 dollars.

hmm

Engine Designation D16Z6 w/ Neck Diameter of Crank at .865" (22mm)
Engine Designation D16Z6 w/ Neck Diameter of Crank at .944" (24mm)

where is this measured?

Re: tore down my Z6 today...pics...thumbnails
 

I've seen a couple big power builds using 0.010" under cranks and King Alecular bearings.

The-o-rectally, as long as you have oil pressure, surface hardening doesn't mean so much. Unless you detonate, which shoves the rod down hard enough to displace oil film + contact bearing with crank; this is what causes upper bearing shell wear.

Given the average lifespan of a turbo D16 at 200+ whp, turning or replacing the crank is probably a non-issue... do whatever is cheapest.

id love to get a few more opinions on this

Re: tore down my Z6 today...pics...thumbnails
 

its cheaper to get another crank anyway. The bigger the journal, the more surface area. Not like its that much of a reduction but id just get another crank for the peace of mind. That and not having to deal with getting the machine work and custom bearings etc

Re: tore down my Z6 today...pics...thumbnails
 

Id just get it turned and run it.For a modest D16 who cares.But if a crank is cheaper to get then go for it.

who's to say the new crank isnt fucked up?

Re: tore down my Z6 today...pics...thumbnails
 

a crank i buy would have likely been turned
turning it wont cost me anything
im shooting for ~20 psi and ~300 hp
