Sav -
Sorry to hear about the loss.
Have already sourced a replacement block or are you hoping all the damage is internal and reusing the current block?
Like Hustler, I built the motor and sized the turbo to exceed my power requirements. As long as I don't get stupid with the tune or have cooling issues, it should hold together for whatever abuse I put it through.
As soon as the budget allows, I'll start tracking the car and see how well the theory holds up...

Epic carnage update:
Pretty cut and dry case of number 4 rod failure. Popped the rod, snapped it into 3 clean pieces, punched a nice neat hole in the block. The piston came up to the head, just barely tapped it (nearly no damage to the head), but it did blow the head gasket when it came up, which quickly joined the oil and coolant passages and spun all the rod and main bearings in short order.
These motors are ******* TANKS, though. I drove this motor 1 mile at 55mph with 3 rods intact. It ran, albeit roughly, until I shut it down myself. It even kept oil pressure until the end.

4, 3, 2, 1. The rest of the rods actually look straight.

I think the head is salvageable, provided the cam bearing caps are good (doubt it). The bottom end is a throwaway.

Purchased.
This thread is now about what I need to purchase to get the '99 motor swapped into my '94 chassis. I will keep my '94 alternator, purchase a longer oil feed line, and use my COP setup, but what am I missing?

And may or may not have already purchased it....![eek5](https://www.miataturbo.net/images/smilies/eek5.gif)
Edit: Crap, too late.
Anyways, what about controlling the VCIS?

****. It's within the VIN range, but it was an auto motor and only a few of the cars in the range were affected. I'll check the endplay when I throw it in, but I don't think it will be an issue that needs immediate involvement.
