I recently acquired a TD05 from a GC8 body STI and am wanting to install it on my GF8 WRX wagon(EJ20G). Anyway, what I was wondering is, am I going to need to upgrade my injectors to keep up with the new turbo? Will an ECU reflash be required? I am also going to be installing a set of headers on this puppy so I just want to get all my ducks in a row before I follow through with my plan. Thanks for any help.

Just swapping the turbo probably won't require you to do anything, however if you start upping the boost, which is usually what most people do when they put a bigger/better turbo on, then you will probably need to look at larger injectors.

 

Are you just running stock boost levels? What boost levels do you plan to run with the TD05?
