this is for my 2.4 built ld9 for my cavalier(street car) NO-ONE makes any downpipe for this car so it will be custom and the turbo im using is a gt3582 that will lag until 4k to 4.5 with a rev limiter of 7k but from my 44mm wastegate should i recirculate it or screamer pipe(keep in mind that its a street car still)?

 

im using the same turbo on my 06 cobakt 2.2. spools at around 4500 rpm. recirculate the wastegate. keep our planet clean and noise free

 

ok thanks again by the way how does "our" turbo sound in boost or spool up (anti surge ports)?

 

sounds good. you know when its coming since its laggy. i dont have the anti surge ports.

 

oh ok
