hey im a little confused here. I have a d16z6 block i am building up, and i took the stock rotating assembly out of it. I also have a d16a6 with a rod knock. Now in the meantime i want to get my hatch running, and im going to put the rotating assembly from the z6 in the a6, and i was wondering if that was gona drop my compression? My logic behind that is if you put a z6 head on an a6 block, (mini me) you get a boost in compression, up to a theoretical 11:1 C/R. But that same head on the z6 block gives you a c/r of 9.2:1 or similar. So what happens when you put the a6 head onto a z6? Will i have a c/r of 8:1 or will it be stock 9.1:1 of the a6? I want to test out my turbo (RHB52) and i dont really care about this engine since i got the a6 for free (with a header too!). But the lower compression ratio would help my engine run for a longer time. Im running the RHB52 turbo, ford intercooler (a little smaller than the radiator, fits right next to it) 2.25" i/c piping, 330cc injectors, 2.5" downpipe, missing link, stock cx exaust and ecu. Would it be a good move to put the z6 rotating assembly in the a6, or should i just replace the rod/crank and keep the a6 pistons in the a6 block? Thanks for any info you can throw my way.
