They ground the crank 0.25 (0.010)
Heres what journals spec out to Mains 54.75mm/(2.1555in) Rods 44.75m /(1.7620in) Wanted to make sure that ACL race bearings (0.010)/0.25mm would indeed be correct size

I ran duraglide oem spec bearings in my current gsr, but new build is gonna be 82mm Cp 11.0.1 c/r b18c1 eagle h-beam rods, acl race bearings, fully built port & polished p72 head ITR valvetrain Crower titanium retainers, Skunk2 Tuner 2 cams, Undecided if Im gonna run cam gears I have brand new skunk2s but car Is gonna be tunned by Churches again or Do it dyno I like the look of the greddy/toda blue timing belts cut valve covers & exposed cam gears, but this is my daily & I live in the worst state for owning a hopped up Honda CA anyways also have portmatched 68mm skunk2 t/b & intake manifold, 01 H22 injectors,Aem FPR/rail Hondata heatshield, walbro 255, Act streelite / flywheel hd pressure plate & disc 96 spec ITR tranny hasport axles, innovative billet mounts all wrapped up in a 1 owner 99 dc2 aiming for 225 on dynapack made 208 last dyno non-ported head, 60mm exh, apexi intake, new set-up. 2.5" mandrel bent cat back magnaflow resonator/muffler, custome 3" tube courtesy of K&N BPI velocity stack w/K&N 98 ITR header/JDM CAT. Only reason for build car uses oil smokes a lil either piston rings or valve guides either way, have these parts readily avail so ya back to the bearings much input greatly appreciated I dont have an oem repair manual that has specs

Did you get the crank nitrided after the grinding?

If not I would get a used crank and use OEM bearings according to the colour chart. Green all the way across usually doesn't cut it.

It was a very mild grind why would they consider doing the job for me if it will not be reliable ? Why does it need to be re-nitrided if the bearings is what takes the abuse ? Why would they sell.25 bearings as well ?

just fyi, honda crank has a special coating they put on the crank for reliability/longevity, if that coating has been taken off by grinding, ur crank will still work but will not last as long as a crank that has the coating. get a use crank thats still good u will save yourself some headache for doing that.

You guys say get another crank lightly I just spent $105.00 on acl bearings $187 on machine work & balance cant afford to just **** can the crank, it wasnt really bad before the grind just wanted it perfect, cant I just get it coated or something feel like they dont make -0.25 bearings for a reason

Ask the people that ground ur crank if they recoated if after grinding it

you must not know anytihng about a N/a engine.

Jack the compression yo and be mad fast!@!!

his compression is perfect for n/a.

as far as the crank goes, the heat treating honda does only goes so far into the surface. one removed it needs to be retreated and recoated.

Gregsteggy

Well he has everything needed to be fasted by raing the copmpress

Wasnt raised by much I have jdm b18c gsr in the car which yields at 10.6.1 I believe & now its 11.0.1 will help but port & polished head should make a difference along with my fresh intake & exhaust set up, before the exh was bottlenecked & filter was a little small the pleats wernt that big on the apexi intake
