Okay so my d15b7 is puffin black smoke so i am thinking its time for a new motor. I am thinking the 92-95 ZC and i know that this is not reccomended but i have all ready have a budget turbo setup on my d15b7 and that would make it pretty much make it interchangable. Oh and i am gonna be ordering the motor from nippon motors if I purchase the ZC. Now my questions are: Will the ZC run well on my stock P06 for the time being before i bolt up my turbo setup on it? For a transmission just to clarify, the ZC only bolts up to an ex/si tranny? If you had the choice would you rather a d15b or the ZC? I ask this because my friend has a d15b for sale at a comprable price to the ZC. Thanks!
