Any updates on this?
May 17th:
Member on honda-tech sent me 6 factory bolts for the d16 flywheel so the machine shop could use them to plug the stock holes, shave off, then machine down that end of the crank so the rear main seal fits. The bolts were needed because they'll be machining down into them and then pressing a 'repair sleve' on as they call it so it is a smooth surface to prevent the seal from being possibly eaten.
Unsure if they machined the repaired rod journal down yet, but besides that, everything else is good to go! I'll post an update when everything is back in my hands along with hopefully a price breakdown... have a feeling I'm going to need to put another $800 into it bringing it up to a total of near $1,800 between top end and bottom end machine work total.
New oil pump is here along with timing kit. Experimenting with an adjustable Honda F22 cam gear if it measures up the same when it comes in. Going to get the shop to make an adaptor piece to make it bolt to the cam.
ANYBODY KNOW of an adjustable cam gear that will just bolt on just incase this $30 one won't work?

Cam gear is here, it's the correct tooth count and spacing, etc. Now to take it with me to the machine shop and see what they think about modding it to work.
I'll just use the notch

Talk to the shop about making a ring with keyway kinda like this to 'adapt' it.
