will a d15b7 with a d16z6 head run good/well/alright with boost? im installing a greddy kit (partial) on my car it currently has a d16y7 that i borrowed from a friend. dont know whether its mine or his or what, but i might give it back and throw in the d15 with the z6 head and boost that. will it be safe or will the compression rise significantly from the mini-me conversion???

 

please???
