Hi everyone... help me choose ef4 maperformance or evo 9 turbo

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.

Stay away from the MAPerformance turbos. They are junk.


A 9 turbo, those cams, and good pump gas (92 or 93 octane) will make around 350-360whp with an O2 dump.

DO NOT BUY A MAP TURBO. Ever.
