Hi guys. I need your knowledge and opinions on a turbo upgrade. I am looking forward for a better turbo replacement since my current turbo is old school and i believe is worth having something more modern in my baby. At the moment my gt4088 hit 430whp at 1.3 bar and 470whp at 1.5 bar. The power is instant with very best power curve. Fresh rebuild 13b rew engine with large intake and exhaust ports and ra black super seals. I am using hks short t4 devided with 60mm trust 4bolt wg and 46mm greddy bov on custom vmount setup . Which do you think will be a better replacement regarding better spool with higher hp evel at lower boost and more safe (breathe better) for my engine between g35 g40 efr series. I am looking for psr g40 900 t4 devided with 1.06 ar at the moment but i am open for suggestions and i really need you opinions on this. Thanks
