Well decided I'm going to put my new CT-26 with a Turbonectics T4 upgrade on this '90 turbo we just got and I'll take her stock worn out ct26 and have it upgraded to a 60-1:evil2: for my mk2. Q is, what kind of other mods will I need to do? mainly in the fuel? Don't plan on uping the boost off the bat with it. like i said, right now her '90 T is bone stock with 88K.
