The block is the same as the stock Miata block. From the first one in 1990, they were all overengineered for NA and turbo very well. Strong cylinder walls, low compression, oil squirters on the bottoms of the pistons... a guy in our Miata group has been running 15psi on his daily driver/track 1.6 for several years, and the only thing that failed is the thing that fails on all turboed 1.6s - the differential. The 1.8 diffs can take it.
