Hi all looking at upgrading the turbo on my wrx but not sure
how to go about it my car is standard (stock internals and sta has done 10kun engine and gearbox rebuild car is stock apart from 3" turbo back exaust and a computer chip (14.5psi no speedcut) anyway i have a few questions. Will i need to change anything else when i change turbo or should i? Is a td05 with a 20g wheel to big for my car and will i have to change anything? What are the 18g turbos like compared to the 20s also what are the subaru td05s like
