hey iam new here and iam planning to do a d15z1 mini with a Y8 head and going turbo with a si tranny, yea i kno its gonna drop my compression down to 8:4 or some were in the 7s but my question is that is this a good idea to boost the crap out of it with that low of CR or should i use the d16 pistons with forged rods in the d15 to bump the CR then boost it, as of now i have all of these minus the forged rods

it would drop it to 8:1 over on zeal auto, would work well ok but there really wouldnt be an advantage having stock ringlands and low CR, i would mill the head and bump the CR up a bit to have more pickup.

it would work and wouldnt be anything great out of boost
