so this is abit of a noobish question but since i didnt see a noob section im rebuilding my d16y8 and i found that the d15z1 head would boost up the compression like crazy and im wondering how many people have used this setup if its possible and any other info would be great

D.T.P

The d15z1 is vtec-e head. As i recall it only has 2 cam lobes per cylinder vs the d16y8 which has 3. The vtec-e motors were designed to be more gas efficient rather than performance in mind. So if you want to raise compression or gain more power, keep the y8 head and get some new pistons.

FYI check this out: Compression Calculator

You're better to go mini-me (D16Z6 (or A6) block with D16Y8 head), D16A6 or A1 pistons and a D16Y8 or Z6 head gasket. 10.5-11:1 CR

if you want to keep your Y8 block get one of the following pistons to boost compression:
PM6 (D16A6)
PM7/P29 (JDM ZC/USDM D16A1)
PG6 (D16A1)

D.T.P

Jamie, instead of tripple posting with some nonsense and misinformation, next time think about what you are saying?
Minime with z6 or a6? Z6 is vtec.

jamie1985

d16A6 block with Z6 head is a minime

My mistake. Too many number/letter combos! haha All other information is correct and accurate though.

i think ill probly go with the P29 D16a pistons
