I have an 03 wrx here's my mod list
3 inch turbo back exhaust
Sti pink injectors
Perrin Fmic
Stage 3 clutch and flywheel
255lph fuel pump
Stock turbo at 18psi
Cobb stage 2 tuning

My question is. I have a 20g turbo at home I can install would I be able to install it without having to take it to a dyno and just load a new map from Cobb onto the ecu and have no problems. Are my supporting mods efficient?

Your injectors are not sufficient for the 20G. Cobb does not make a map for a 20G turbo, so unless a tuner sends you a custom map, no.

Ok thanks for the input guys. Any suggestions on a sufficient turbo upgrade
