I just put my apexi intake on over the weekend, and since then ive noticed a strange sound. When i lift off the throttle when im in boost, the car makes a fluttering sound coming from the intake. So my questions are: Does a CA18 have a factory BOV? Is that compressor surge? Or are my turbo bearings on the way out? And out of curiosity,what would be involved to put a t28 for a S14 on a stock CA if the turbo is done? Thanks for any help ---

Compressor surge if it’s a new sound ---

Compressor surge. And CA’s don’t have a stock recirc valve. At least my buddies 180 didn’t have one, we even looked at every piece of charge pipe and didn’t find shit. ---

SO if thats compressor surge than would a BOV not remedy that? My 180 has a BOV and I still get that fluttering sound. ---

OK so wat u guys r saying is im not in need of a new turbo right now? Cause im poor ☹ But if all it is is compressor surge, im happy thats easy to fix. ---

there should be a screw that you can adjust. i know with my old sard you had to take the whole thing apart ---

Well I just went out and started lossening off my BOV and I have it all the way down to where it releases at 2000RPM and I’m still getting compressor surge. Is there anything else I can try, it seems like if I go any looser on the adjusting screw it’ll fall out. ---

Maybe it’s not the compressor surge that’s making the fluttering. If the fluttering is coming from your intake then it’s most likely compressor surge, some bovs make a fluttering sound. ---

Its definatly comming from the intake. Just with the way things have been goin for me, i cant be too careful.
