Hi,
I have for sale a 2001 Miata (1.8) main bearing support plate with the required crankshaft main bearing caps.
Parts are in good used condition.

Just FYI, I'm pretty sure that every Miata engine has caps that will accept an MBSP already. The caps are machined with the block, and you cannot interchange caps between blocks without having some rather expensive machine work performed.
$125 is a good price for the MBSP and the oil pan, but those caps should stay with the block they came from

Was not aware they all had that. the caps are spares I had to include for those who may or may not have threaded mains.
A line hone would solve the issues with caps that aren't from the engine. expense depends on your builder.
