Okay I have a problem. I know that you need a vast amount of air to make substantial power with a turbo but my problem is I fully built this ZC and I was trying to used the 50mm D16Z6 throttle body because the ZC throttle body is like 1,1/4” but there is a gap at the bottom of it. I am aware that I can get it welded and I spoke to the guy already but I want to see if there is another way around it (for now) and yes I did search and yes there is only one company that makes a aftermarket TB for the ZC (for $600). So the 1st question is how much power am I going to loose using the ZC throttle body? If you don’t understand how small the throttle body is you can literally take the d16 throttle body and fit the ZC’s in it…so again the question is how much power will I be loosing with the smaller ZC throttle body. I was trying to make at least 270 the most with my setup. I have a fully built bottom end, blockguard, honed, line bored, forged rods, low compression pistons, new bearings, the head is pretty much stock with the ports opened up a little, with a T3/T4 50 trim, 3” all the way back, MSD 6A, Digital AFC , basically new everything . The 2nd question, is there any way I will be able to make at least above that amount with that TB? Can I raise the boost to compensate for the size of the TB to make up for that power loss?
