Un paio di citazini da miata.net giusto per fare un pò chiarezza:
Tale Smokey che ha blocco 2.5 + testa 2.0 dice "I got about 20hp and 30 lb/ft increase from my 2.0. The midrange torque is great!"
E alla domanda su quale rapporto di compressione sia venuto fuori alla fine risponde:
"I used stock 2.5 pistons, net CR is 9.8:1 with 2.0 head, a bit lower than I wanted but I found a CR calculator and the difference between 9.8 and 10.8 (what I wanted) was 4hp max. Not worth the expense of new pistons/rings etc. At least it will be safer for high RPM on pump gas."
