Now since I've decided to go with the turbo, C4 trans and the manual valve body from early posts. What do I need to convert from a t5 trans. What can I keep, what do I have to get. Will the C4 bolt directly to a 88 GT. I'm going to stay under 11lbs of boost with the 67mm turbo. What size torque converter should I use I'm waiting on my Turbo kit so I'm trying to get my trans together.
