speedo, easy...
water temp, easy...
oil pressure/temp, easy...
fuel level, not so easy, the ohm range is not like anything aftermarket... i guess changing the fuel sender unit or measuring the ohm readout and making a control box for it will be in order...
afr + egt, haven't seen a production car to ever have those... those are tuning tools only (wouldn't expect a factory car to go out of tune and expect the customer to tune it).

Key is proper fueling/ignition under boost. I'm willing to bet the stock MB pistons and rods are good to go. hp
speaking of aluminum blocks, those yes all have aluminum pistons ? this is my first car with a aluminum block but my previous iron block cars had cast steel pistons ... how were the iron blocked first generation miatas ?

For us, the biggest issue is finding a proper donor vehicle at a reasonable cost.

are we talking about finding a theft recovery or something so you don't hack apart a new car ?
either way, good luck, you're the first person to come across this place that has mentioned doing this that i do not fear for. :-P you have a shop and the time and experience to do it ...
