What size turbine are you running? T4 P trim? T3 Stage 3? T3 Stage V? I run a .77 A/R Stage V T3 turbine on my 3.5L 350Z. I would recommend at least a Stage V .63 A/R with the 62-1 compressor. You could also give the sales staff a call at 805-581-0333 and they can spec out the exact turbo that would best suit your needs...

Are you sure its not a result of backpressure from your downpipe and exhaust system?

My personal opinion you should switch to a P trim with a .63 A/R if you are going to switch compressors to a 62-1. But like I said, call the sales staff at 805-581-0333 and they can spec out the exact turbo that would suit your needs...
