Hey guys, I have a R33 gtst and after emptying out my cat last week, I realized that when I put my foot down, the boost will rise to 16psi which is what it's set at, hover there for a sec, then continue to rise over 20psi. I'm aware that this is due to the decatting and the wastegate can't keep up with the flow. However what I need help on is what to do next, I was planning to upgrade my turbo soon anyway, would that be the best bet ? If so, what turbo do you all recommend ? Or any other options ? It's a daily driver so I'd prefer a mix between response and power. Following are the mods on the car;
-PFC
-FMIC
-KLS power spirit turbo, .63 A/R
-550cc denso injectors
-Z32 AFM
-3'' turbo back exhaust (empty cat)
-splitfire coil packs
-walbro fuel pump
Possibly more from what I recall
Thanks for any feed back guys, will be greatly appreciated
