so i purchased a car a while back that wosent running right so instead of messing with it swapped my z6 in it..finnaly looking at the motor its a d15b7 with a vtec head thus fore makeing it a mni-me? the heas is stamped with a po8-4(or p08-3) thats is the z6 head if im not mistaken...many people said it was a jdm d15.but wint that make it a mini still. also it has writeing on the intake manifold like a chalky yellow writeing that say d16z6 iwas wondering how much of a power gain will i be looking at..i read Bauleyscivic writeup and it only had time slips posted

 

bump need to know what the difference between p08-3 and p08-4 heads
