There is a "performance specialist" near me that recently moved even closer to me (15minutes away, now 10 minutes away), and I stopped there today and asked a few questions.
They specialize in Rotary's, but also do work on BP engines and headwork. Example: They have about 2 dozen RX7's there, but they had a Honda S2000 that they said they just redid the head on. I told the owner of the place that I plan on doing a block build possibly late fall / early winter. I said I'd pull everything and drop the complete block off with the head. I mentioned that I want the block honed and new rings installed. I think he said he could do it, and it would take brand new stock sized rings. Then I told him that I plan on going with a bigger turbo, and I would install new rods because rods are the BP's weak point. He said he'd have to send the pistons and the new rods out, because the wrist pins get pressed in. Is that a fact? I never had a 4 cyl Miata engine apart, but I assumed they had clips? As far as my cyl head, I stated that on a non VVT BP application, the '99 head is supposedly the way to go, but I want it to be gone over. He said they could port and polish it, and basically whatever else I'd need done.
So here's what I'm thinking:
Stock pistons on M-tuned rods...balanced everything
New bearings
Hone / re-ring
As far as head work, suggestions????

You could do all that yourself and save yourself a ton of money. I let the machine shop put my pistons/rods together for $5 each since they were already doing an overbore
Edit: Porting the head isnt' all that bad either since you're not actually porting anything just smoothing all the casting flaws. I had alot of fun doing mine and I'm about to do another for a member here
