ok so i recently installed an engine into my crx a d16a6 but this ones weird its like i barely step on the gas and u can hear the intake roaring a little already and from the past 2 engines that i had like this one they didnt do that what could it be is something adjusted wrong

 

you are going to really have to explain it better then little roaring.

 

i had that happen to me once, turned out it was a litte gremlin stuck in my intake!! dam japanese!! j/k can you describe the "roaring" for us?

 

Was this a A6 for A6 swap? What did you have before this latest A6 swap?
