hi all,
who does ion gas nitriding of crankshafts on the west coast that can be trusted to do a superior job? I will need to send my crank out for my tr4 2289cc engine build. It would be nice to find someone that can grind(1st under),balance,blue-print,nitride,final grind my crank at one shop. I have not found anyone reliable in vancouver canada to do this (nitriding)(i might not have found them) so i am looking for suggestions. I am looking for close to 1/10th thou accuracy.

Havenít used them myself but Castillo's Crankshaft Specialty here in SoCal has a good reputation.

Call David Anton at APT, he can help you out with a source.
As for the ion nitriting, you'll need to supply them with type steel they are nitriting, or get samples lab tested, David may also be a big help here as well. THe trick with ion nitriting when compared to salt bath nitriting is you don't have the warpage, but you have to have rack to mount the crank in, in a manner that does not streess it and basiclly lets the part dangle.
