I'm suprised there's not a denomination for the low and high compression versions....Originally Posted by Wingman0
I have the high comp. version (99-05 Miata), i was thinking about using the lower comp. block with my head, but i've always been a fan of high comp. low boost engine.. but i guess 12psi isnt very "low boost" for 10:1 compression lol.... probably should switch to the 9.5:1 block from the 94-97 Miata's.
