Hello guys just got an 2003 evo 8 have been doing a lot of research on what to do I want to get around 360 whp out of it heard it's pretty safe I need help. It has a crappy obxr eBay turbo in it and it's going out. Has shaft play and burning a lot of oil. So I figured might as well upgrade to a bigger/better turbo. Heard the evo 9 Td05hr-16g6-10.5t turbos are very good. But someone is selling an maperformance ef4 turbo and I don't know which one to get. Heard the ef4 spools pretty late around 4-4.5 k rpm

Planning to get HKS cams 264 intake and 272 exhaust cams found some for very cheap good condition.

Has already a bigger intercooler not sure what kind
Full Exhaust
Ingen full cold air intake setup
Stock injectors (do I need bigger injectors)
255 walbaro fuel pump

Just really looking for some input here what to do and what mods to add.
